An important amendment, it appears that copper grease that I have used on the new glow plug threads may interact with the aluminium body of the engine. One could use lithium grease in that case, but I have not seen a problem with the copper grease.
What was the reason for you to replace the glow plugs? I have a smoke at a cold start from my 1.6 hdi and diagnostic shows a glow plug fault. Checking with a mechanic he seems to believe it is the glow plugs problem and says that they need to switch on at any temperature. Did your smoke in the morning reduce after changing them?
Many thanks for the video it was very much appreciated. This is a nightmare of a job, even if all does go well. Doing it with a torch and camera could not have been easy! I would recommend anyone watching the whole video though, for me, I particularly liked you showing us the problem you had getting the plug out after it was fully loose. They just don’t tell you about problems like this in manuals and it is problems like this that terrifies me most! I have a Peugeot 307 1.6hdi (dv6ted4a) and the Peugeot garage told me that this job would “initially” cost a few hundred pounds. When I asked them what they meant by “initial” they said that a plug might break when they try to take it out. In which case the head would have to come off. I hate cars, though your videos help a lot. Many thanks.
Thank you, much appreciated. It was not too easy to position the camera and the torch in a way that all is visible, it is just too tight. I was also quite apprehensive to do this, hearing all sorts of stories with glow plug tips breaking in the head. Having done it once, I would say that it is not too difficult and I am no mechanic in any shape or form. As for the breaking of tips, I am not too sure what to say. I am sure it is possible, but these glow plugs are tough. I had a few attempts to break them with pliers (end of video) and did not really manage to do anything apart from scraping the metal. If I were you I would replace them myself, they are pretty cheap and certainly not few hundred pounds. I am also certain that I would be a lot more careful doing the job than the mechanics would. Take your time and it should be ok. Good luck
Nightmare job? Try changing the pipes that go from water pump to thermostat... That SURE is a nightmare! I had to replace them cause i riped one while removing egr valve. I really had a bad time doing this... HORRIBLE! but 30€ for the used part worth it!
@@moremoleculesYeah I was paranoid about doing it, hearing tales of the plugs breaking but there's nothing fragile about them. Gave them some bashes against concrete and it didn't do a thing to them. 🤷🏻♂️
Thank you Chris, although looking at it now it could have been filmed better. It was one of my first videos, so less light and position of camera might have been better ;-)
I have just managed to replace mine .... 3 were swollen tips. I took some advice from the mechanic that did my MOT that really helped. Here it is Unscrew the plugs as in the video with a torque wrench, when they feel like they are sticking spray some WD40 or decarbonizer onto the thread ,, leave for 15 Wind the plug back down ,,, wind it back up ... try and avoid completely unthreading it as that will put on the lateral force you don't want spray and repeat as long as your patience level allows The winding up and down wears off the carbon on the tip but it must have lubricant so allow time for it to penetrate down the shaft
I have changed mine about a week ago. One of the glow plugs didn't come out easily. Screwing back and forth didn't help much. I was able to even pull it out about 5mm before it was getting stuck. So, what I did is just spray wd40 and turn while pulling it. It took a long time but managed to get it out.
Great info, I've the feeling someone has broken the tip of the glow plug in the cylinder head on a car I've just bought, but theirs a noise just started in the back of the engine like an exhaust blowout, from what I've read some people will just drive the car and the compression in the cylinder head blows the tip out, again great information and patience's.
Hi David, yes a broken tip will be rather unfortunate. There are drill kits for broken injectors, although I am not too sure if they will be any good for just the tip. Yes, that is a possibility for the compression of the cylinder to blow it out. If that does not work out, the head needs to come off unfortunately, but good luck, hope it works out.
My 2007 307 HDI with 170.000 , once the engine starts, I notice a rough idle and misfiring, only with cold engine. The engine struggle to run smoothly until it warms up and then it’s ok. Do you think it could be the glow plugs ? The dashboard glow plugs light never comes on ! Could be the relay ? Thaaank you !
Yeah, mine has done that for quite some time now and it is not the glow plugs or thr relay (I have changed both). I suspect it is a little bit of slippage of oil from the turbo and burning oil is not really smooth for the engine. Have a look at the exhaust fumes when this happens and most likely you will see a bit of puff of blue-ish smoke, once that clears the running is smooth.
@@moremolecules thank you i will look the fumes. I was wondering if I need to take it to the mechanic for having a look or not. I was fancy to change the glow plugs but not sure as you say if it’s the cause of the problem , in addition there is the risk to break the plug inside the block … Once the engine is warm it runs perfectly fine , it’s just the cold start that sounds and vibrates ugly.
@@bernatcarnerbonet3251 Yeah, forgot to say that the 1.6HDi does not really need the glow plugs, unless the temperature is really low, say 5C they do not switch on. The 1.6HDi are not like the older 1.9D where they light up every single time, so that is why you do not see them on. Difficult to say, should you give it to a mechanic. I have not yet traced the problem, but if you take it to a mechanic and it get fixed, let me know😁
@@moremolecules thank you for your advice. I have sent videos and explained the issue to my experienced local mechanic who deals with my cars except for for 307 which is my school car for practicing , so he told me some points I’m going to to translate and summarise for you. He already told me it’s not the glow plugs. I live in Barcelona and temps are around 20C now when cold !
When it breaks , it break the tip of glow, but dont worry ! With an steel rod hammer tip in to the cilinder then take of injector and with an 6mm magnetic extractor u take tip from cilinder through injector hole! No need to take off cilinder head!!!
That is a good tip! Although, it maybe be difficult to get the injector out. I tried hammering the tip with pliers, but I could not break it. They more frequently break at the thread.
many thanks for the video, I have seen it before, but now it looks as if I am going to have to change one, might be a good idea to put a set in, thanks again, very helpful ... in spite of all the criticism of the 206 during the 12 years we have had ours it has done well really.
Many thanks indeed for the good words, hopefully it will be easy to get them out. I think that the 1.6HDi gets too bad reviews everywhere, but all in all I think it is extremely reliable engine if consumables are changed on a regular basis. Good luck
Hey. i've just finish changing my glow plugs. the went out without any problem. it is not easy to break heating tip but VERY easy to bent part of plug where you connect it. bend 2 old ones when trying to get them out. have c4 grand picasso and access is just terrible, all work done using mirror and torch.
Hi done my glow plugs today as this is same as 1.4dtci ford fiesta thank you so much ? Can you tell me on the fuel filter the out let at front that goes to injectors when you disconnect this ouoe and turn the engine over is fuel serpose to come out or not thanks
Hi Philip, fuel should not come out of anywhere! Nevertheless, if you disconnect one of the lines from the fuel filter and turn the engine on, I suppose fuel will come out, the fuel pump will push fuel. You do not want to be doing that though, air will come into the system in places that are hard to clear afterwards. This is only an assumption though, I have not done it before in this way
That was well told. One thing I have a Ford Fiesta mk7 1.4 tdci all the same at the back of engine can you tell me when you are undoing the nuts holding the egr pipe to the engine what else is it letting you move that make the removal off the plugs
Hi Philip, not too sure I understand your question. The plastic connectors on the glow plugs are just push fit, so just pulling them out. Your model might be slightly different, as some are with nut on top that needs to be unscrewed. The EGR pipe is a bit different, as it has the intercooler, the EGR itself and the EGR pipe that goes on top of the engine. Can you re-phrase and I will be more than happy to answer
Ahh, yes, the nut and bolt hold the plastic piece that the filter airbox sits on. The problem was that the EGR intercooler is screwed onto this plastic. So, in order to remove this plastic one needs to remove the EGR intercooler, which would have been too much of effort for me. Happy New Year to you too!
Thank you the reason I took the out let pipe of was to see if the fuel was coming out of filter as car won't start I no pump is working but if no fuel comes out it won't go to injectors to start car what do you think
Hi Philip, check all cables and pipes if they are connected. Make sure the two lines to the fuel filter are not swapped. You have to prime the priming pump/bulb until hard, to clear air. If everything is in order plug it to a diagnostic such as PP2000/DIagbox or Lexia if it is Citroen and see if there are any error codes that can help trace the non-starter. Good luck.
in the past ive had the end part left in the head so removed the injector then tapped the end part of glow plug into the cylinder and fished it out with a magnet via the injector hole
Many thanks fr the advice, appreciate it. One needs to remove the injector which in itself might bring other problems, but probably one of the few ways to remove the broken tip.
Hi Ppp, the heater plug relay is screwed on the metal behind the left-hand side headlight. It is very well hidden and as difficult to replace. It is on the metal towards the engine. Apologies, not too easy to explain the position. It is also difficult to reach there and feel, but if you can, it has several metal/alluminium fins and it is held by one bolt.
Did it have any codes like a P1351? My neighbor's partner has that code and cranks but won't start. Wondering if it's the fuel heater in the fuel filter box or the glow plugs or their relay...
There probably was a P1351, but your neighbour's problem is not related to this, if the car is 1.6HDi. The glow plugs and the relay would not prevet the car to start, they are there to make it easier. It will start without working glow plugs. It is most likely fuel related, check for fuel line leaks or purge the air in the fuel system. It could be of course something else.
@@moremolecules Yeah, it has bad compression in one cylinder. It had been starting and running really poorly before, and then after changing the EGR it refuses to start at all. Has a P0405 which I can't clear. Apparently the new EGR fried the ECU because the two pins which control the solenoid both show ground... Verified with an ECU repair shop that one of the pins is supposed to be B+. I was just trying to figure out what to advise him as far as weather to scrap it or try to fix it, but with a bad ECU, bad EGR, blown head gasket, injectors that need cleaning / or replacing and apparently needing glow plugs as well it just seems like this vehicle has been too abused and poorly maintained to keep investing in it... I didn't even list everything I suspect of being wrong with it... You can see the virtual compression test I did on the vehicle here if you're interested... ua-cam.com/video/LZ0f-Z--i3M/v-deo.html
@@sailorbob74133 Fried ECU is probably the biggest problem, but with so many problems it is probably not worth keeping it or trying to resurect it unfortunately. I will check the video, looks like a good thing.
Hi, thanks so much for your Videos. Could you please tell me how to remove the air scoop, so that I can get my head over the back of the engine, so I can see the glow plugs. Thanks
Hi i have 1.6 peugeout expert 2007 model..i have this egr problem nearly 2/3 years van have bo power smoking when first start then ok..mechanic tested it only his machine shoved glow plug..some one said glow plug..not sure what to do..?engine has very litle noise now i can hear 1- is it worth repair? 2- if i get it repaired (change glow plug or change egr)would it be ok?thanks for good video
Hi Ertan, If I were you I would clean the EGR in the first place and see if that helps. Difficult start could be EGR. Glow plugs are only needed when it is really cold (< 0C), otherwise they do not operate.
@@moremolecules actually didnt start at all fee time after that its ok..engine light come on then gone..now always starts first time nearly 6 month..but no power and smells bad
Hi first ape, the closest to the gearbox in numbered 1 or the closest to the timing belt is 4. From left to right (looking at the front of the engine), 4321.
@@moremolecules ua-cam.com/video/cjVDHsvVNtk/v-deo.html I just watched your other video, you said that one with more fuel was No.2 which would mean 1234 ... ? Thanks
Apologies, the actual numbers are 4321 (left to right), it was my mistake that I said N 2. I only meant like number 2 from left to right, rather than the actual cylinder numbers. So, in the video, I should have said injector number 3
Hi Philip, it does not quite work like that. Once you remove the bulb air will come straight in. As far as I understand (not too familiar with the mk7) it is self priming, i.e. with cranking the fuel pump will bleed itself and remove air. Crank it for a bit and see if it starts. It may need a bit of cranking. Careful not to flatten the battery. If it does not work try some sort of EOBD scanner to see if there are any errors.
@@chatchatty2155 I have not seen this before, but it seems to be relatively common in ford. It seems that it maybe a fried ECU or disconnected wire from on of the injectors. Check all wires from injectors if they are broken. You may also test for continuity between the wires and a negative on the body somewhere or the negative terminal of the battery, apparently should be ~200K ohms. See if that helps somehow. If it is a fried ECU, that maybe problematic, as you need new ECU and re-flash.
Thanks so much for this video. It shows what in incredibly stupid design this engine is. Something which took 10 minutes on my last car and didnt require half the engine to be disassembled!
Hi Colin, thank you for the encouragement! There are a few other things that should have been done better, but then again it is one of the most popular engines around with other manufacturers. Some of the surrounding stuff (airbox, crankcase breather, etc.), imho, are better accomplished by ford, although the 1.6TDCi is the same as the 1.6HDi.
Just a note, when putting anti-seize on things like spark plugs or glow plugs it changes the torque spec - I don't remember off the top of my head if it lowers it or raises it - you might want to check into that...
No, only petrol engines have ignition coil packs. There are no spark plugs in diesels, so no ignition coil packs to provide electricity for the spark of fuel. It is all based on pressure, hence the HDi or high pressure direct injection, no spark
@@philipmaguire9209 Extremely unlikely. The glow plugs in the HDi only operate when the temperature is rather low, say ~3C. Even without a single working lgow plug, the HDi will start, although a bit more difficult. In 2-3min it will warm up and the glow plugs are no longer needed. If you suspect misfire, plug in OBDII scanner and see if there are any errors, otherwise it is a bit of a guessing game.
@@philipmaguire9209 EGR stays high? I do not understand what that means. I meant to check for any error codes. It should be open/close rather than high.
Hi CSR ALN, works both ways as a normal wrench (small bit to twist to switch ways), anticlockwise (unscrew) and clockwise (screw). The torque bit is the screwing only, but that is probably obvious. Maybe I did not get the question right.
@@moremolecules That's right. I'm looking for a torque wrench than can operate counter-clockwise but I haven't found it yet. I'm planning to set the torque to 16Nm or so to avoid glow plug breakout when unscrewing it. At the moment I can't even pull the caps out, they must have a safety lock or something.
@@csraln6748 I am not too sure, I will have to test it with mine, but I think if you set the torque wrench to say 8Nm and then undo the glow plugs, it will not go past that. Anyway I would set it to 8Nm, 16 is too much. Overall the torque setting for these is 10-12Nm, 16Nm will be too much. I tried with 8Nm and it worked.
@@moremolecules Here's a guide for NGK glow plug replacement. For M8 thread they recommend max 20Nm when unscrewing and 8.5Nm when screwing. ua-cam.com/video/W9lzWWGj8LM/v-deo.html I'm actually working on a Peugeot 308 1.6 hdi. I finally got the glow plug connectors out by pulling sideways with a pair of pliers. Then I slightly unscrewed the glow plugs and poured a bit of motor oil on each of them. Hopefully that will lubricate the thread day on day until the replacement.
What is your opinion about EGR delete? I've got a Ford Fiesta Mk8 that has a different EGR cooler than the pre-2013 engines, and I see that it's a lot more difficult to install an EGR plate, not to mention the EGR fault codes that these engines pull up when you fit an EGR blocking plate. So, I found a second EGR cooler with the valve, and I'm thinking to connect the EGR cable to the spare EGR valve, so to trick the ECU thinking that it controls the valve, but the real engine EGR valve is closed. It's a one year old engine and I don't want to mess with reprogramming the ECU in case I void my warranty.
Hi Aris, well, I am not really for removing/delete the EGR valve. With regular cleaning it is that big of a deal. The problem is the NO oxides without an EGR valve ot with an EGR delete. I do not want to give advice, but personally I would keep my EGR valve, less NO oxides, less pollution.
0.03 ohms is good, but it is not the best method. They might be working, but rather slow to heat up anything. It could be the relay as the computer cannot distinguish between the relay and the glowplugs.
@@badrijan9704 There might be ways, but I have not heard of something easy to be done. You could simply replace it, relatively cheap, but access behind the headlight is difficult.
Nice video! FYI; If the engine was/is running lumpy and your Glow Plugs were fine, you have a problem with 1 or more Injectors that are leaking from the Nozzles. It's very common. Does the Anti Polution warning come on when it's cold starting?
Dude GREAT video....I'm going to attempt the removal / replacement this weekend.....what i have 4 you is a MUST HAVE headlight ....it's called (Nightbuddy)...that aside, in the mean time DPF REMOVED straight pipe EGR delete... different response much les shifting gear and beter powerband in low RPM... ps.volvo v50 1.6 tdci. 335.000km.

Thanks. I'm not too sure actually. The weather is much warmer now, so the glow plugs would not operate. I think the new glow plugs may have helped a bit, as it is not as lumpy as before, but have to wait for cold weather to know for sure.
@@markoknezevic2712 Unfortunately, the glow plugs did not help with the cold, lumpy start, still the same. I think one of the injectors might be slightly leaking and potentially contributing to the cold lumpy start. A potential cause is old seals on the turbo cartridge and leaking of bit of oil in the intercooler, then on the first start blowing the oil with the air in the cylinders and somewhat blueish smoke + lumpy start. Will address these eventually.
@@moremolecules I have exactly the same symptoms and the glow plugs are not working also. The wierd thig is that sometimes the car starts and doesn't smoke at all, and at other times it starts but idle's roughly and you can smell unburnt diesel from exhaust. The engine is not very well designed, the new 8 valve engines are much better and have fewer problems as they age.
Hi Joao, Generally the hear is to have differential expansion of the materials. It is really good question though, generally metal and other materials are more pliable with heat, i.e. less difficult to break or shatter.
Hi Mate.. Thanks for this video very thorough. I've got a Citroen c4 picasso with a P1351 fault code. It's got about 85000 miles on the clock. The car starts and runs OK even in winter so I did not bother changing the glow plugs till now. Sometimes I feel the car won't accelerate as it should its a bit slow to respond. Will changing the glow plugs fix this issue or do they only effect the cold starts. Thanks
I have a P1351 now as well but it's the middle of summer so i'll ignore it a bit. But an answer to the acceleration problem you wrote of (even if it may be a bit late for you): I had such problems, getting worse and worse until the car almost stalled while accelerating - in my case it was the diesel filter, seems like this wants to get changed more frequently. Still though mine is idling roughly from time to time, haven't found that one.
Yes, it is about the same as the tightening torque. It was probably a bit misleading in the video as my torque wrench does not do reverse torque. So in effect it did not matter how much I put it on. There are torque wrenches with reverse torque, but I have not found one that is affordable.
I do not think changing the glow plugs cured the rough idle. Currently, the weather is much warmer and there is no rough idle, so hard to tell. I suspect the turbo seal on the compressor side might be seeping a bit of oil and the oil is causing the rough idle and a dash of blue smoke at cold start.
I had a 1351 code. All my glowplugs were dead. Took all the precautions to get them out in one piece. Due to the carbon build up of not burning and having a larger diameter at the end, all of them snapped off at the tip. No way getting them out without special tools. I made a guide to hammer the tips into the cylinders and then removed the injectors in order to get the tips out with a flexible magnet. This is quite a drama. You need a camera with light wich is not bigger than 7mm diameter in order to locate the tip. The magnethead should be no larger than 4mm in order to make the angle because the pistons have a highest point in the middle.
They were all sheared off at the same spot,at the beginning at the black thin tip. The thread was no problem. Not the pulling makes them snap but the turning, makes a horrible clicking noise. WD40 or penatration oil, hot engine didn’t work.
@@moremolecules First of all, thank you very much for your early reply. When you say behind the left headlight, there are two green roles in a square box. You are talking about them.
I also wonder that when I first turn the ignition of the vehicle, the glow plugs do not need to have energy for a short time, I turn on the contact, there is no electricity, don't look at the spark plug cable
@@salihcolak677 For the 1.6HDi it is kind of silver with fins. The fins and top part are aluminium. It is really stuffed just behind the left headlight and it is hidden a bit. If one if looking from the front is on the right on the left side, behind the headlight.
@@salihcolak677 On 1.6HDi, the glow plugs do not get heated/operated unless the outside/coolant temperature is really low. It has to be ~0C in order the glowplugs to operate. If the coolant is warmer than 7C you will get nothing, no glowplugs, they are not needed.
For the glow plugs, I suspect it depends on where you live and how often they were required to operate. The EGR will probably have clogged on the closed position, otherwise you would have noticed the rough idle on cold start. I would do the EGR and test the glow plugs

I am not too sure about all the errors. Try disconnecting the MAF sensor and see if it behaves the same. Disconnecting the MAF will make it go into a restricted mapping. If it improves you may need to replace the MAF.
@@moremolecules Thats the problem mate the MAF sensor is plugged in already and when unplugged theres no change in behavior ive done a live data reading on the car with the MAF plugged in and the values show 0.000 :(
Hi Carlo, it depends on the outside temperature really. The HDIs do not need the glow plugs unless the temperature is really low, say ~0 C. If the outside temperature is >5 C you would not see the glow plugs illuminating at all.
On these specific glowplugs the unscrewing torque is ~8Nm and tightening is 10Nm. Hope this helps, but if buying new ones check the torque recommendations on the box.
One trick by NGK! If your torque is not able to unscreew them put sone oil around glow plugs and drive for 6 more days and then try again... ofc possible if at least one is working so there is not limp mode
Brilliant video Bro thank you France cars soo hard change to everything well done. For example if 2nd glow plug does not work can l replacement number 2 or need all glow plugs and my car is citroen c4 l have code p1351 it is mean glow plug preheater relay socket is not working or glow plugs not working . car is normal working no any problem.
It is not a problem to replace only one glow plug. You do not need to replace all of them. At least try to make sure it is the same make, to minimise differential heating. You could test them with a multimeter to see if there is resistance between the head of the glow plug and the body of the engine. It could be the relay that it is faulty.
Can I ask anyone on here if there hdi chucks or is hesitant in 4th or 5th gear with faulty glow plugs? Mine definitely has a rough idle when cold but it is also hesitant in 4th and 5th gear when accelerating up hill or overtaking.
Some of your problems have nothing to do with the glow plugs. The glow plugs only work below certain temperature (depending on the model, say below 0C ) to heat the block and aid starting up. On the HDi they do not operate while driving and completely stop working after a few minutes starting from cold (
Hi. How many km did the Partner run bevore the change of the glow plugs? I have a C4 Picasso 2012 @70.000km and have to do the EGR valve. So it is one work to change the glow plugs.
@@moremolecules I am an electronic specialist. So I know/belive, if the motore is hot, the glow plug is hot. So the resistance is higher. The glow plug is an PTC. The funktion ist very good, it's mor to clean them and use of copper paste like you. But I want to use ceramic grease, so not 3 different metal.
@@Eagle71_Tirol I agree, there will be some variance in the measurement of the resistant in relationship to the temperature. I was only talking about if it is completely broken, i.e. resistance is sky high/infinite vs. some fairly low resistance. If it is anything below 2ohms, it is most likely good.

I used work in ford and the guy was over us used all ways tell us take the car for a drive and get it up to operating temp and then remove glow plugs he said it makes it easier how true this is I don’t know
Hi Dylan, yes, because they are different metals they would expand with different rates and it may be easier to take out. My problem was that the engine was hot to begin with, but by the time I started taking them out, it was already cold.
customers dont want that then manufacturers made it delibaratelly hard accesibly that most of peoples will go to mechanic repair shops and pay for service@@moremolecules
My diagnostics shows pre heat relay and glow plugs and my accelerator is heavy and gets clogged up no cleaner addictive work also steering is heavy and break pwrmoance is work don't know weather it's injectors or pump
Not too sure what you mean by heavy accelerator, but generally the glow plugs and associated relay will give difficult starting in lower temperatures, perhaps smoke. Once the engine is up to operating temperature, the glow plugs do not operate. The heavy steering is probably from the pump. Check if you have enough fluid
Wish me luck I sprayed them with WD40 New glow plugs will come after two days maybe and when they come fun will begin P.s I'm never buying a french car again no offense but I think the mechanic sleep with the engineer's wife
An important amendment, it appears that copper grease that I have used on the new glow plug threads may interact with the aluminium body of the engine. One could use lithium grease in that case, but I have not seen a problem with the copper grease.

I have just managed to replace mine .... 3 were swollen tips. I took some advice from the mechanic that did my MOT that really helped. Here it is
Unscrew the plugs as in the video with a torque wrench, when they feel like they are sticking spray some WD40 or decarbonizer onto the thread ,, leave for 15
Wind the plug back down ,,, wind it back up ... try and avoid completely unthreading it as that will put on the lateral force you don't want
spray and repeat as long as your patience level allows
The winding up and down wears off the carbon on the tip but it must have lubricant so allow time for it to penetrate down the shaft
You need to be in a good calm mood and have plenty of time ... so take it easy and slow
Good advice 🙂
I have changed mine about a week ago. One of the glow plugs didn't come out easily. Screwing back and forth didn't help much. I was able to even pull it out about 5mm before it was getting stuck. So, what I did is just spray wd40 and turn while pulling it. It took a long time but managed to get it out.
Thank you so much for the video! I noticed my glow plugs went bad i decided to sell the car.. too much hassle these glow plugs 😃
Man, you've done a really god job and even a better video of it. Thank you very much for that!
Thanks Wojciech, really appreciated for the heads up.

Great video thanks for taking the time to produce it for UA-cam 👌
Your videos are just brilliant !
I hope my plugs come out as easy as yours did. nice video man.
Good luck, fingers crossed.
Great info, I've the feeling someone has broken the tip of the glow plug in the cylinder head on a car I've just bought, but theirs a noise just started in the back of the engine like an exhaust blowout, from what I've read some people will just drive the car and the compression in the cylinder head blows the tip out, again great information and patience's.
Hi David, yes a broken tip will be rather unfortunate. There are drill kits for broken injectors, although I am not too sure if they will be any good for just the tip. Yes, that is a possibility for the compression of the cylinder to blow it out. If that does not work out, the head needs to come off unfortunately, but good luck, hope it works out.
very very good video , nice to see one so clear and you can under stand it thanks very much for doing it
Many thanks indeed derek for the kind words.
My 2007 307 HDI with 170.000 , once the engine starts, I notice a rough idle and misfiring, only with cold engine. The engine struggle to run smoothly until it warms up and then it’s ok. Do you think it could be the glow plugs ? The dashboard glow plugs light never comes on ! Could be the relay ? Thaaank you !
Yeah, mine has done that for quite some time now and it is not the glow plugs or thr relay (I have changed both). I suspect it is a little bit of slippage of oil from the turbo and burning oil is not really smooth for the engine. Have a look at the exhaust fumes when this happens and most likely you will see a bit of puff of blue-ish smoke, once that clears the running is smooth.
@@moremolecules thank you i will look the fumes. I was wondering if I need to take it to the mechanic for having a look or not. I was fancy to change the glow plugs but not sure as you say if it’s the cause of the problem , in addition there is the risk to break the plug inside the block … Once the engine is warm it runs perfectly fine , it’s just the cold start that sounds and vibrates ugly.
@@bernatcarnerbonet3251 Yeah, forgot to say that the 1.6HDi does not really need the glow plugs, unless the temperature is really low, say 5C they do not switch on. The 1.6HDi are not like the older 1.9D where they light up every single time, so that is why you do not see them on. Difficult to say, should you give it to a mechanic. I have not yet traced the problem, but if you take it to a mechanic and it get fixed, let me know😁
@@moremolecules thank you for your advice. I have sent videos and explained the issue to my experienced local mechanic who deals with my cars except for for 307 which is my school car for practicing , so he told me some points I’m going to to translate and summarise for you. He already told me it’s not the glow plugs. I live in Barcelona and temps are around 20C now when cold !
When it breaks , it break the tip of glow, but dont worry ! With an steel rod hammer tip in to the cilinder then take of injector and with an 6mm magnetic extractor u take tip from cilinder through injector hole! No need to take off cilinder head!!!
That is a good tip! Although, it maybe be difficult to get the injector out. I tried hammering the tip with pliers, but I could not break it. They more frequently break at the thread.
many thanks for the video, I have seen it before, but now it looks as if I am going to have to change one, might be a good idea to put a set in, thanks again, very helpful ... in spite of all the criticism of the 206 during the 12 years we have had ours it has done well really.
Many thanks indeed for the good words, hopefully it will be easy to get them out. I think that the 1.6HDi gets too bad reviews everywhere, but all in all I think it is extremely reliable engine if consumables are changed on a regular basis. Good luck
Thanks for a supervideo on howe to change glowplugs
Great video with lots of detail, thank you very much.
Thanks for posting this. It's convinced me not to try it on my '07 Citroen C5, where there's very little space between the engine and the scuttle.
It's not that bad though. I agree that on yours it is a bit more difficult with the limited access, but still doable
Hey. i've just finish changing my glow plugs. the went out without any problem. it is not easy to break heating tip but VERY easy to bent part of plug where you connect it. bend 2 old ones when trying to get them out. have c4 grand picasso and access is just terrible, all work done using mirror and torch.
Yes, they can break at the top and well done with the limited access on the C4, great work
Thanks for showing it was really helpful👍👍
Hi done my glow plugs today as this is same as 1.4dtci ford fiesta thank you so much ? Can you tell me on the fuel filter the out let at front that goes to injectors when you disconnect this ouoe and turn the engine over is fuel serpose to come out or not thanks
Hi Philip, fuel should not come out of anywhere! Nevertheless, if you disconnect one of the lines from the fuel filter and turn the engine on, I suppose fuel will come out, the fuel pump will push fuel. You do not want to be doing that though, air will come into the system in places that are hard to clear afterwards. This is only an assumption though, I have not done it before in this way
That was well told. One thing I have a Ford Fiesta mk7 1.4 tdci all the same at the back of engine can you tell me when you are undoing the nuts holding the egr pipe to the engine what else is it letting you move that make the removal off the plugs
Hi Philip, not too sure I understand your question. The plastic connectors on the glow plugs are just push fit, so just pulling them out. Your model might be slightly different, as some are with nut on top that needs to be unscrewed. The EGR pipe is a bit different, as it has the intercooler, the EGR itself and the EGR pipe that goes on top of the engine.
Can you re-phrase and I will be more than happy to answer
What I ment was the nut and bolt you took of at back of engine what did it release thanks happy new year to you
Ahh, yes, the nut and bolt hold the plastic piece that the filter airbox sits on. The problem was that the EGR intercooler is screwed onto this plastic. So, in order to remove this plastic one needs to remove the EGR intercooler, which would have been too much of effort for me.
Happy New Year to you too!
Thank you the reason I took the out let pipe of was to see if the fuel was coming out of filter as car won't start I no pump is working but if no fuel comes out it won't go to injectors to start car what do you think
Hi Philip, check all cables and pipes if they are connected. Make sure the two lines to the fuel filter are not swapped. You have to prime the priming pump/bulb until hard, to clear air. If everything is in order plug it to a diagnostic such as PP2000/DIagbox or Lexia if it is Citroen and see if there are any error codes that can help trace the non-starter. Good luck.
in the past ive had the end part left in the head so removed the injector then tapped the end part of glow plug into the cylinder and fished it out with a magnet via the injector hole
Many thanks fr the advice, appreciate it. One needs to remove the injector which in itself might bring other problems, but probably one of the few ways to remove the broken tip.
Do u know where heater plug relay is I have a 1351code on my Peugeot partner 1.6 Origin 2008
Hi Ppp, the heater plug relay is screwed on the metal behind the left-hand side headlight. It is very well hidden and as difficult to replace. It is on the metal towards the engine. Apologies, not too easy to explain the position. It is also difficult to reach there and feel, but if you can, it has several metal/alluminium fins and it is held by one bolt.
1351 code is 99% more likely the glow plugs not the relay
Did it have any codes like a P1351? My neighbor's partner has that code and cranks but won't start. Wondering if it's the fuel heater in the fuel filter box or the glow plugs or their relay...
There probably was a P1351, but your neighbour's problem is not related to this, if the car is 1.6HDi. The glow plugs and the relay would not prevet the car to start, they are there to make it easier. It will start without working glow plugs. It is most likely fuel related, check for fuel line leaks or purge the air in the fuel system. It could be of course something else.
@@moremolecules Yeah, it has bad compression in one cylinder. It had been starting and running really poorly before, and then after changing the EGR it refuses to start at all. Has a P0405 which I can't clear. Apparently the new EGR fried the ECU because the two pins which control the solenoid both show ground... Verified with an ECU repair shop that one of the pins is supposed to be B+. I was just trying to figure out what to advise him as far as weather to scrap it or try to fix it, but with a bad ECU, bad EGR, blown head gasket, injectors that need cleaning / or replacing and apparently needing glow plugs as well it just seems like this vehicle has been too abused and poorly maintained to keep investing in it... I didn't even list everything I suspect of being wrong with it... You can see the virtual compression test I did on the vehicle here if you're interested... ua-cam.com/video/LZ0f-Z--i3M/v-deo.html
@@sailorbob74133 Fried ECU is probably the biggest problem, but with so many problems it is probably not worth keeping it or trying to resurect it unfortunately. I will check the video, looks like a good thing.
Hi, thanks so much for your Videos. Could you please tell me how to remove the air scoop, so that I can get my head over the back of the engine, so I can see the glow plugs. Thanks
Which engine is that? Mine does not have an eir scope, but it is on the old side of things.
Hi i have 1.6 peugeout expert 2007 model..i have this egr problem nearly 2/3 years van have bo power smoking when first start then ok..mechanic tested it only his machine shoved glow plug..some one said glow plug..not sure what to do..?engine has very litle noise now i can hear
1- is it worth repair?
2- if i get it repaired (change glow plug or change egr)would it be ok?thanks for good video
Hi Ertan, If I were you I would clean the EGR in the first place and see if that helps. Difficult start could be EGR. Glow plugs are only needed when it is really cold (< 0C), otherwise they do not operate.
@@moremolecules actually didnt start at all fee time after that its ok..engine light come on then gone..now always starts first time nearly 6 month..but no power and smells bad

My car is ford fiesta mk7 don't have the priming bulb but if I buy one shale I just connect it to out let on filter and pump till I see some fuel
Hi Philip, it does not quite work like that. Once you remove the bulb air will come straight in. As far as I understand (not too familiar with the mk7) it is self priming, i.e. with cranking the fuel pump will bleed itself and remove air. Crank it for a bit and see if it starts. It may need a bit of cranking. Careful not to flatten the battery. If it does not work try some sort of EOBD scanner to see if there are any errors.
@@moremolecules ok thanks I will try that if I plug in a a hand held scanner I have a foxwell scanner nt310 will that help me
@@chatchatty2155 yes, the foxwell scanner will help, but try cranking for a bit, it should start once it clears the air.

@@chatchatty2155 I have not seen this before, but it seems to be relatively common in ford. It seems that it maybe a fried ECU or disconnected wire from on of the injectors. Check all wires from injectors if they are broken. You may also test for continuity between the wires and a negative on the body somewhere or the negative terminal of the battery, apparently should be ~200K ohms. See if that helps somehow. If it is a fried ECU, that maybe problematic, as you need new ECU and re-flash.
Thanks so much for this video. It shows what in incredibly stupid design this engine is. Something which took 10 minutes on my last car and didnt require half the engine to be disassembled!
Hi Colin, thank you for the encouragement! There are a few other things that should have been done better, but then again it is one of the most popular engines around with other manufacturers. Some of the surrounding stuff (airbox, crankcase breather, etc.), imho, are better accomplished by ford, although the 1.6TDCi is the same as the 1.6HDi.
Just a note, when putting anti-seize on things like spark plugs or glow plugs it changes the torque spec - I don't remember off the top of my head if it lowers it or raises it - you might want to check into that...
Yeah, it's ~20% increased torque when there is copper grease.
Do peugeot 307 hdi 1.y estate have coil packs,?
No, only petrol engines have ignition coil packs. There are no spark plugs in diesels, so no ignition coil packs to provide electricity for the spark of fuel. It is all based on pressure, hence the HDi or high pressure direct injection, no spark
@@moremolecules Thanks mate got issue with misfiring in neutral only might need need glow plugs perhaps?.
@@philipmaguire9209 Extremely unlikely. The glow plugs in the HDi only operate when the temperature is rather low, say ~3C. Even without a single working lgow plug, the HDi will start, although a bit more difficult. In 2-3min it will warm up and the glow plugs are no longer needed. If you suspect misfire, plug in OBDII scanner and see if there are any errors, otherwise it is a bit of a guessing game.
@@moremolecules EGR says high ? OBD Says
@@philipmaguire9209 EGR stays high? I do not understand what that means. I meant to check for any error codes. It should be open/close rather than high.

Does that torque wrench work anticlockwise (unscrew) as well as clockwise(screw)?
Hi CSR ALN, works both ways as a normal wrench (small bit to twist to switch ways), anticlockwise (unscrew) and clockwise (screw). The torque bit is the screwing only, but that is probably obvious. Maybe I did not get the question right.
@@moremolecules That's right. I'm looking for a torque wrench than can operate counter-clockwise but I haven't found it yet. I'm planning to set the torque to 16Nm or so to avoid glow plug breakout when unscrewing it. At the moment I can't even pull the caps out, they must have a safety lock or something.
@@csraln6748 I am not too sure, I will have to test it with mine, but I think if you set the torque wrench to say 8Nm and then undo the glow plugs, it will not go past that.
Anyway I would set it to 8Nm, 16 is too much. Overall the torque setting for these is 10-12Nm, 16Nm will be too much. I tried with 8Nm and it worked.
Yes, it does not work as I said, no matter what torque setting it is, it will unscrew as needed, hmmm.
@@moremolecules Here's a guide for NGK glow plug replacement. For M8 thread they recommend max 20Nm when unscrewing and 8.5Nm when screwing.
ua-cam.com/video/W9lzWWGj8LM/v-deo.html
I'm actually working on a Peugeot 308 1.6 hdi. I finally got the glow plug connectors out by pulling sideways with a pair of pliers. Then I slightly unscrewed the glow plugs and poured a bit of motor oil on each of them. Hopefully that will lubricate the thread day on day until the replacement.
What is your opinion about EGR delete? I've got a Ford Fiesta Mk8 that has a different EGR cooler than the pre-2013 engines, and I see that it's a lot more difficult to install an EGR plate, not to mention the EGR fault codes that these engines pull up when you fit an EGR blocking plate. So, I found a second EGR cooler with the valve, and I'm thinking to connect the EGR cable to the spare EGR valve, so to trick the ECU thinking that it controls the valve, but the real engine EGR valve is closed. It's a one year old engine and I don't want to mess with reprogramming the ECU in case I void my warranty.
Hi Aris, well, I am not really for removing/delete the EGR valve. With regular cleaning it is that big of a deal. The problem is the NO oxides without an EGR valve ot with an EGR delete. I do not want to give advice, but personally I would keep my EGR valve, less NO oxides, less pollution.
I had 0.3 ohm on all 4 ,do you know it is ok?
Yes, 0.3ohms, should be alright for all of them
Hello, I tested the glow plugs with multimeter without removing them from the car and I had 0.03Ω
is that okay ? I have p1352 fault
0.03 ohms is good, but it is not the best method. They might be working, but rather slow to heat up anything. It could be the relay as the computer cannot distinguish between the relay and the glowplugs.
@@moremolecules any way to test the relay ? I tried testing it with the FAP app, there a section to test actioners and it said it was OK
@@badrijan9704 There might be ways, but I have not heard of something easy to be done. You could simply replace it, relatively cheap, but access behind the headlight is difficult.
@@moremolecules I have c4 ii it's on very easy location on my car, it's outside of the engines fusebox
@@badrijan9704 You could then replace it, but I would say that more than likely it is the glowplugs rather than the realy.
Nice video!
FYI; If the engine was/is running lumpy and your Glow Plugs were fine, you have a problem with 1 or more Injectors that are leaking from the Nozzles.
It's very common.
Does the Anti Polution warning come on when it's cold starting?
Yes, it is possible, although the glow plugs really only operate if the temperature is

Great video, did it cure the lumpy cold idle in the end?
Thanks. I'm not too sure actually. The weather is much warmer now, so the glow plugs would not operate. I think the new glow plugs may have helped a bit, as it is not as lumpy as before, but have to wait for cold weather to know for sure.
@@moremolecules Hi, what was the final result? :)
@@markoknezevic2712 Unfortunately, the glow plugs did not help with the cold, lumpy start, still the same. I think one of the injectors might be slightly leaking and potentially contributing to the cold lumpy start. A potential cause is old seals on the turbo cartridge and leaking of bit of oil in the intercooler, then on the first start blowing the oil with the air in the cylinders and somewhat blueish smoke + lumpy start. Will address these eventually.
@@moremolecules I have exactly the same symptoms and the glow plugs are not working also. The wierd thig is that sometimes the car starts and doesn't smoke at all, and at other times it starts but idle's roughly and you can smell unburnt diesel from exhaust. The engine is not very well designed, the new 8 valve engines are much better and have fewer problems as they age.
@@markoknezevic2712 I still think is a leaky injector, as I get a bit of vibration ~1500rpm
Hello,
Can i ask why you heat the engine before? You recommend to change the plugs in a warm state??
Hi Joao, Generally the hear is to have differential expansion of the materials. It is really good question though, generally metal and other materials are more pliable with heat, i.e. less difficult to break or shatter.
Hi Mate.. Thanks for this video very thorough. I've got a Citroen c4 picasso with a P1351 fault code. It's got about 85000 miles on the clock. The car starts and runs OK even in winter so I did not bother changing the glow plugs till now. Sometimes I feel the car won't accelerate as it should its a bit slow to respond. Will changing the glow plugs fix this issue or do they only effect the cold starts. Thanks
Hi Arul, no it will not fix the acceleration issue. The glow plugs are pretty much for very cold weather, for example
@@moremolecules Thank you very much for the clarification.. 👍
I have a P1351 now as well but it's the middle of summer so i'll ignore it a bit. But an answer to the acceleration problem you wrote of (even if it may be a bit late for you): I had such problems, getting worse and worse until the car almost stalled while accelerating - in my case it was the diesel filter, seems like this wants to get changed more frequently. Still though mine is idling roughly from time to time, haven't found that one.
great work. Are you sure the loosening torque is 8 newtons?
Yes, it is about the same as the tightening torque. It was probably a bit misleading in the video as my torque wrench does not do reverse torque. So in effect it did not matter how much I put it on. There are torque wrenches with reverse torque, but I have not found one that is affordable.
great work man well done!
Help me,position sensor camme+sensor giri peugeot 308 hdi 2008. Good biutiful video.
Not too sure what the question was about?
So did it cure the rough idle then ?
I do not think changing the glow plugs cured the rough idle. Currently, the weather is much warmer and there is no rough idle, so hard to tell. I suspect the turbo seal on the compressor side might be seeping a bit of oil and the oil is causing the rough idle and a dash of blue smoke at cold start.
the problem of the malfunction of the heaters is that it does not make the regenerations to the fap.
I had a 1351 code. All my glowplugs were dead. Took all the precautions to get them out in one piece. Due to the carbon build up of not burning and having a larger diameter at the end, all of them snapped off at the tip. No way getting them out without special tools. I made a guide to hammer the tips into the cylinders and then removed the injectors in order to get the tips out with a flexible magnet. This is quite a drama. You need a camera with light wich is not bigger than 7mm diameter in order to locate the tip. The magnethead should be no larger than 4mm in order to make the angle because the pistons have a highest point in the middle.
Hi Simon, Wow, that was quite a feat! Well done and for sharing, much appreciated. Where was the tip broken at? At the base or a smaller black piece?
They were all sheared off at the same spot,at the beginning at the black thin tip. The thread was no problem. Not the pulling makes them snap but the turning, makes a horrible clicking noise. WD40 or penatration oil, hot engine didn’t work.
By the way, white smoke at cold start is gone👍

Hi Salih, the glow plugs relay is behind the left headlight. It is really inside and very difficult to get to.
@@moremolecules First of all, thank you very much for your early reply. When you say behind the left headlight, there are two green roles in a square box. You are talking about them.

@@salihcolak677 For the 1.6HDi it is kind of silver with fins. The fins and top part are aluminium. It is really stuffed just behind the left headlight and it is hidden a bit. If one if looking from the front is on the right on the left side, behind the headlight.
@@salihcolak677 On 1.6HDi, the glow plugs do not get heated/operated unless the outside/coolant temperature is really low. It has to be ~0C in order the glowplugs to operate. If the coolant is warmer than 7C you will get nothing, no glowplugs, they are not needed.
Thanks for the idea it was really helpful. 👍
Hi. My cars is 263oookm and i never changed glow plugs or EGR valve. Maybe it is time soon to do this??--
For the glow plugs, I suspect it depends on where you live and how often they were required to operate. The EGR will probably have clogged on the closed position, otherwise you would have noticed the rough idle on cold start. I would do the EGR and test the glow plugs

Hi craig, can you be a little bit more specific why it was so painful to watch.
I have aproblem with glow plugs. They dont apear at the dash board at all but the engine starts..
Hi Carlo, it depends on the outside temperature really. The HDIs do not need the glow plugs unless the temperature is really low, say ~0 C. If the outside temperature is >5 C you would not see the glow plugs illuminating at all.
how much turned away and how much tight ,,in nm
On these specific glowplugs the unscrewing torque is ~8Nm and tightening is 10Nm. Hope this helps, but if buying new ones check the torque recommendations on the box.
One trick by NGK! If your torque is not able to unscreew them put sone oil around glow plugs and drive for 6 more days and then try again... ofc possible if at least one is working so there is not limp mode
@milek021 Good advice

car is normal working no any problem.
It is not a problem to replace only one glow plug. You do not need to replace all of them. At least try to make sure it is the same make, to minimise differential heating. You could test them with a multimeter to see if there is resistance between the head of the glow plug and the body of the engine. It could be the relay that it is faulty.
@@moremolecules thank you so much
Can I ask anyone on here if there hdi chucks or is hesitant in 4th or 5th gear with faulty glow plugs? Mine definitely has a rough idle when cold but it is also hesitant in 4th and 5th gear when accelerating up hill or overtaking.
Some of your problems have nothing to do with the glow plugs. The glow plugs only work below certain temperature (depending on the model, say below 0C ) to heat the block and aid starting up. On the HDi they do not operate while driving and completely stop working after a few minutes starting from cold (
Very useful Thank you
How many km does the car have btw
~90,000miles or ~145,000km at the time of replacing the glow plugs
Hi. How many km did the Partner run bevore the change of the glow plugs?
I have a C4 Picasso 2012 @70.000km and have to do the EGR valve.
So it is one work to change the glow plugs.
If they are good, i.e. ~1ohm resistance, you do not need to replace them. Mine was on ~88,000 miles.
@@moremolecules I am an electronic specialist. So I know/belive, if the motore is hot, the glow plug is hot. So the resistance is higher. The glow plug is an PTC.

@@Eagle71_Tirol I agree, there will be some variance in the measurement of the resistant in relationship to the temperature. I was only talking about if it is completely broken, i.e. resistance is sky high/infinite vs. some fairly low resistance. If it is anything below 2ohms, it is most likely good.
Thanks for the video..slightly too bright but never mind
It was the best I could do in the darkest corner of the engine.
'slighty too bright' 🤣🤣🤣 you didn't live up to this guys level of recording, go do it all again lol great video man, doing 1 and 4 on my c4 picasso tomorrow, fun times
I used work in ford and the guy was over us used all ways tell us take the car for a drive and get it up to operating temp and then remove glow plugs he said it makes it easier how true this is I don’t know
Hi Dylan, yes, because they are different metals they would expand with different rates and it may be easier to take out. My problem was that the engine was hot to begin with, but by the time I started taking them out, it was already cold.
Looks like a nightmare off a job.is it easier from under the car
Hi Tony, it's not as bad as it looks. There is no access from underneath, it can only be done from the top.
Mate there's plenty of room. Try a PSA 2.0 tdci on Ford Galaxy.
Hahah, I agree, I meant more the camera and light/torch and then it becomes a bit tight.
Has anyone P1352 ? 1.6 e-hdi 115
Thenks
its mission impossible on 207 unless you dont take all engine out
Yeah, they make them more and more difficult to work on. It is what the customer "wants".
customers dont want that then manufacturers made it delibaratelly hard accesibly that most of peoples will go to mechanic repair shops and pay for service@@moremolecules
My diagnostics shows pre heat relay and glow plugs and my accelerator is heavy and gets clogged up no cleaner addictive work also steering is heavy and break pwrmoance is work don't know weather it's injectors or pump
Not too sure what you mean by heavy accelerator, but generally the glow plugs and associated relay will give difficult starting in lower temperatures, perhaps smoke. Once the engine is up to operating temperature, the glow plugs do not operate. The heavy steering is probably from the pump. Check if you have enough fluid
Cheers
brilliant
Wish me luck I sprayed them with WD40
New glow plugs will come after two days maybe and when they come fun will begin
P.s
I'm never buying a french car again no offense but I think the mechanic sleep with the engineer's wife
And they are all out no problem engine was not hot even
@@kikopaterov6781 Well done, although sometimes they are stuck and all sorts of problems follow, but well done!
This is why you shouldn't buy french cars
Hahaha, they all are pretty much the same, once one has spent enough time to drive them tinker with them.
French are artist how to make things more complicated
There is a truth to that.😁
@moremolecules starter motor place in hdi is on pretty bad place
Thanks a lot for this great video!
