- Опубліковано 29 тра 2024
- In today’s video I explain how the Landcruiser VDJ200 series intercooler setup works, how to remove it and how to clean it out to maximise efficiency and performance. This easy and quick maintain tip is essential for those who own modern day turbo diesel vehicles.
I show how the air travels through the intake system of the Landcruiser V8 twin turbo diesel and why we need an intercooler mounted in our engine bay to increase performance.
I provide step by step instructions to remove your intercooler and the associated wiring and vacuum hoses safely and without damage.
We then put the intercooler through a thorough chemical degrease and clean to ensure all oil residue is removed, providing us with a clean and efficient intercooler that will lower intake temperatures and increase performance.
At the end of today’s video I test the vehicle using OBDII software and factory charged air intake temperature gauges to test against a base line reading to see exactly how much of a difference an intercooler clean actually makes to your 4WD turbo diesel.
The vehicle I was working on today is a 2014 Toyota Landcruiser 200 series Sahara. Engine - 4.5L V8 Twin turbo diesel.

Nice video! You wont make explaining of even obvious things to sound boring. I'm former mechanic, but just every minute was worth of watching and comparing the results was something I appreciate. 👌
Thanks mate, I really appreciate that. It's encouraging to get this type of feedback. Hopefully you'll enjoy the video's to come.
Cheers, Nathan.
Lol are you joking? It's 30 minutes of him banging on
Great and very informative segments, so glad I stumbled on to your channel, love your work and the supportive data you present 👍
Thanks mate, glad you have managed to find some value from the channel.
Cheers, Nathan.
I can barely nail two bits of wood together but I found this video really interesting. Thanks for sharing Nath !
Haha, thanks Jim 👍
Great little home project if your stuck with nothing to do.
Cheers, Nathan.
Another great video I don't have a Cruiser but your info is great for generally most diesel cars.
Thanks mate, I'm glad you were able to find this video helpful.
Cheers, Nathan.
Amazing video, I plan on cleaning my IC after seeing this video. Another point / benefit of having a top Mount is that it’s easier to take off. Mines a FMIC and you have to take the whole front bar off.
Thanks and love the outback looking scenery where you live, it’s beautiful
Awesome, all the best with your clean. I'm sure your engine will thank you for it.
It sure is a great area, although I have recently moved to a landscape very different. Great to move around and discover new places.
First time I've seen you. A masterclass in vid making. Consider me subscribed !
Thanks mate, I appreciate that feedback and glad to hear that you enjoyed the video.
Cheers, Nathan.
Great video mate. Thanks for making this one. I will be doing mine for sure.
Cheers mate, glad you enjoyed it.
Hopefully it can bring some benefit to your vehicle too.
Cheers, Nathan.
Excelente video todo muy claro, saludos desde Costa Rica.
Thankyou, I appreciate that.
@XploringOz thank you for your video.
Using your video I was able to clean my 150 Prado’s (1GD) intercooler while getting my EGR/EGR cooler and intake manifold cleaned.
The mechanic was amazed that I did a good job, thanks to your info.
Thanks mate, I'm glad to hear that you got some use from it and now you'll know it will make some difference.
How did you feel the car responded to having the EGR and intake manifold cleaned? Big difference?
@@XploringOz Nath to be really honest the difference on feel is minimal (you can tell it is there but it's not like day and light in my case)
However knowing the car breathing a little better and cleaning gives me peace of mind.
Also good for engine longevity anyway :)
@@andylo6845 Thanks for sharing. I will probably look at getting one next year sometime when I get around to some power upgrades on the engine. It definitely will help for overall economy and engine longevity.
Cheers.
I've just recently done my intake and throttle body and compared commercial EGR cleaners with a 75/25 mix of kerosene/white spirit. I found both to be equally efficient at dissolving EGR/PCV muck. From your go here it looks like kerosene was the most efficient. Maybe the optimal process would be a good soak in of kerosene with some agitation in the form of air bubbling or blasting followed up with a spirit rinse and air blasting for complete drainage.
Great video, gonna have to add this to the to do list
Cheers mate, all the best. Annoying job, but worth it in the long run.
Cheers, Nathan.
Clean my intercooler last 3 years ago.. then i pulled my intercooler last night to have it clean again.. to my surprise, my intercooler was super clean it had a little(almost dry) thin film of oil and pour in some degreaser and denatured alcohol to clean the internals, it was also clean.. Also drain my ebay modified catch can..
Car is a diesel fortuner 2.5kd-ftv
Awesome, can't complain with that result! Hopefully it stays this way for years to come 👍
I used petrol for mine on the Ranger because it was what I had on hand. Worked a treat.
The best treatment is the one you have. Glad to hear it worked for you and hopefully this video gives you some confidence it will make a difference.
Cheers, Nathan.
Excellent Video so clear and concise Thankyou
Thanks, glad you enjoyed it.
Cheers, Nathan.
Fair play, really enjoyed this thanks.
Excellent work and very helpful. You are awesome. My intercooler isn't so easy to remove though :-) . Many thanks for explaining so well
Thanks mate, appreciate the feedback and glad you got some value from it. All the best with your clean.
Cheers, Nathan.
Cool mate, but I would just use the kerosene.
That pink stuff u mixed with the water does bugger all (I have used the same stuff) and metholated spirits is pretty useless at removing diesel oil too. Also that pink stuff is caustic so if you don't get every drop of it out of the intercooler it has a chemical reaction with the aluminum which quickly corrodes & it will actually start blocking the cores withing an hour. I have been down that road too..
Another good thing about metholated spirits is that it will mix with water (or in this case absorb the water). Some people use it if they get water in their Gasoline because it absorbs the water droplets and then it mixes (without bubbles) with the fuel. Then the water and metolated spirits burns cleanly with the fuel.But it makes the fuel a weaker octane though.In this instance it does help remove the Kerosene quite well.
Cheers Nathan, another great informative video. Thanks for more tips and tricks on 200 series maintenance. These diesels definitely need a catch can to minimise oil ingress in the intake air system. 👍👍
Thanks mate. Glad your enjoying these videos.
They certainly do. I'll be switching over to a Provent Catch Can soon, replacing my current HPD. It will be interesting to see whether this makes any difference...
Cheers.
To be clear, oil in a diesel's intake has ZERO effect on performance and can actually help prevent valve recession. It's the carbon/ soot from the EGR when mixed with oil residue from blow by that causes the issue :) HOWEVER : If you have detected even a small amount of dusting ( Refer Nathan's other vid's ) cleaning out your intercooler internally and externally as per vid is recommended as it will also reduce the amount of grit already in your intake which will eventually end up in your engine. I have seen VDJ200 Intercoolers almost completely blocked externally from bugs etc and therefore spiking air intake temps.
Spot on MJHMech.
Great stuff! Lots of information
Thanks, glad it was helpful.
Cheers, Nathan.
Flush it with water. Then flush with hydrocarbons and drain it into a seperate container. Then save the dirty solvent and let it settle. You can salvage it and use it as starting cleaning fluid next time or if anything else you need to clean...bolts,parts ect
Thanks mate, didn't think about this. Appreciate it 👍
@@XploringOz no problem mate. I'm a spray Painter so seeing solvent going to waste saddens me haha
@@DarrenBoxhall Well I leant something new, so I'll give it a go. Cheers 👍
When cleaning oil and grease from concrete and parts I've found Shellite to be the most effective. Try Shellite on grease stains on concrete you won't go back to degreaser. I think you'll find it even more effective than Kero.
Cheers, I'll definitely have a look into it for the next cleaning
@@XploringOz Bunnings sell Shellite , I use it to clean injector nozzles; it’s the best
I haven't used anything but shellite in living memory.
Thanks well done. With your scrap meths fold a coffee filter paper into quarters place in a funnel pour in meths it will be strained n clean enough to reuse for cleaning
Great and informative video mate thankyou, i've been putting mine off must do it next service. BTW you dont have to pretend the hair dryer belonged to the missus, we wont judge. :D
Cheers mate, appreciate the feedback.
Haha, the truth comes out...
Hi,
Very much appreciated for 👍 explaining
Glad it was helpful!
Top video! Thank you for sharing.
Awesome, thanks 👍
That is just brilliant. Always looking for ways to maintain my Mahindra XUV 500 diesel myself and reduce mechanic costs. Yoshi
Thanks mate, glad this was helpful.
That's interesting, i have the cheetah too, pls tell me you have a yt channel it's goin to be relieve from the mechs because they don't treat our xuvs properly
Enter comments from Japan. My Suzuki is 660cc. That's why it's a very small intercooler. Your technique is wonderful. I was allowed to refer to it. I washed the intercooler with kerosene. Thank you.
Thank you very much! Glad you enjoyed the video.
Thanks, Nathan.
@@XploringOz I support your video from far away from Japan. I'm looking forward to the next video.

@@isachilcat Thanks Isao, I appreciate your support!
Great vid mate. Fully detailed. You're the guy ya want to buy a secondhand car off lol.
Haha, cheers mate. Too bad I won't be selling this vehicle anytime soon1
Great video Mate! Very well done and instructional, lots of tips, it will certainly come handy.
Would you be able to confirm if those sensors on the back of the intercooler are boost pressure and air intake temperature?
Thanks a lot
Thanks mate, appreciate the comments 👍
I haven’t seen any confirmation of these sensors, but given their style and placement it is highly likely one will be boost pressure and the other temperature. I can’t fond other sensors that would take these measurements elsewhere in the pressurised intake lines.
Max Germasi , yeah mate they are
G’day Nathan, good on you,... cleaning the pipes from inside. When the 2 fans on top the inter cooler will be installed? Video? Yep, we are very much interested in and it should be a small simple and easy job and nothing to break. Your tech vics are spot on and I will copy that after you finished... haha.. thanks and cheers
Thanks mate 👍
The other video will be a few weeks away yet due to other commitments, but I believe I have all the components ready to go, so it’s definitely happening. It should be a relatively straight forward job, just have to organise the wiring 👍
Hopefully it all works well and provides some extra performance to the vehicle.
Great video, with the software you had going is there any sensors for the fuel consumption? That would definitely cement the results further.
Cheers mate.
Between the software and the Ultra-gauge I would have access to the fuel consumption information, however I would have a guess that the test sample size would have to be very large to accurately capture any benefit. As I'm sure cleaner the intercooler would provide fuel benefits, I believe it would be minor and there would be so many other factors (environmental and vehicle) that could/would effect the results, making it very hard to determine if the clean was the reason for the change.
I'll definitely try to include as much data in my future video's as possible.
Cheers, Nathan.
i like the debugging
Nice Work Thanks.
Thanks mate, appreciate it.
Awesome video Nath! Thanks for the indepth review.What was the software you were using and was it difficult to get a hold of?
Thanks mate 👍
So the software is Toyota Techstream. It was a nightmare to install and get working. I spent about 8 hrs trying to get it to work before shipping the computer to my brother-in-law in IT to setup it up.
Unfortunately I can’t do a video on that setup due to my limited knowledge 🤦♂️
Cheers, Nathan.
Hi Greg! I recently bought this and it was provided with detailed install guide. You cant go wrong with this. ;) www.ebay.com/itm/TIS-Toyota-Techstream-GTS-2021-Ver-15-30-026-Lexus-Scion-Diagnostic-tool-kit-OBD/183981244532?ssPageName=STRK%3AMEBIDX%3AIT&_trksid=p2057872.m2749.l2649
Thanks and Well done.
Thanks for watching!
Did this clean today and everything went well until the blue and pink wire's came out of the MAP sensor plug resulting in a code P0107. So it turned into a bit of a mission on a Sunday arvo LOL, all sorted now. Thanks for the tutorial on the flush, intercooler is like new now.
I'm glad you managed to get it sorted in the end! Hopefully that intercooler clean is still providing some benefits for the engine!
Cheers, Nathan.
great video, just did the exact same procedure and it worked a treat a small but definite improvement in performance but i'm a little disappointed in the poor job catch cans are doing i didn't expected to see so much oil being stuck in there, even yours with a catch can after 25,000 kms seemed a lot of oil still getting thru
Thanks mate. There definitely is a small improvement there, small but noticeable. Anything we can do help the vehicle run a little cooler and more efficiently is definitely a win in my books.
Yeah, I don't think any catch can will work perfectly, I will have another video coming out soon enough where I switch the catch can to a different brand. It will be interesting to see whether that will make much, or any difference to the amount of oil captured over time.
Cheers, Nathan.
@Jim Barrows For sure. And I'm sure we'll see this when I compare the results between the two as well.
Your intercooler is the oil catch can. No worries. Its doing the job.
Great video.
Thanks!
Hi Nath, any chance you could give us some insight into toyota techstream? I know you can get an older version of the software from ebay? I got a 2009 LC200 so i not that fussed on having the latest software, but would love to hear your thoughts on it since you been using the software.
Hey mate, so yes. The TechStream software has been a great feature and advantage to see some data from my LC200, however it wasn't an easy process to install. I purchased the mini VCI cable on eBay, however downloaded my software from an online public forum (can't remember exactly which site).
Installing the software was a nightmare. I tried for hours and couldn't get it to work. This is because it requires a unique code from Toyota (which customers don't have access to) and this needs to be bypassed. I ended up sending my laptop to a family member in the IT business who managed to install some software that bypass' the need to enter the codes. I with I could provide more info, but I just don't know (not the most IT savvy).
I am definitely glad I have the software though. Able to see and diagnose fault codes, change settings (volume of lock/unlock beeps & remote window opening function etc.). It also has the ability to check all sorts of figures of the engine and supporting parts. Definitely recommend if you are able to get it working.
Cheers.
Will the pro vent 200 stop that oil ?
Nice video, very well explained. Just one question. The kerosine really cleaned and turned black. Why not do it twice until you see a lighter colour of the fluid indicating you flushed the black oil residues?
There's no reason you couldn't repeat this process until cleaned, however I just did it the once 👍
Top vid mate
Cheers mate 👍 appreciate it
Hey mate did you replace or check the Map Sensor just under the intercooler where the little black hose went to?
Hey mate, negative. There was on indication that there was any fault with the existing system, so no replacement was necessary in this instance.
My Saab 9.3 convertible intercooler have to be clean. Good expertise to let me do the same. Thanks. N
Awesome, good news 👍
Thank you. Watched 1.5x playback speed. Here for general information due to owning different turbo diesel vehicle. Concept is same.
Glad this was helpful, thanks for the feedback 👍
Awesome video have you done a test with the fan intercoolers?
Still working on it, but it's definitely coming..
Cheers, Nathan
HI, Thanks for teh video, What is the Blue Liquid ?
Hey mate, so this is just Kerosene 👍
Be interesting to see a intercooler performance loss video on spot lights. So many say not to add and even some people had warranty issues stating that blocked the air flow to much.
For sure, there’s no doubt lights and bullbars will effect airflow into the radiator and intercooler. I haven’t included this into my testing at present, but I will be doing tests in relation to top mounted ‘pusher’ fans to see whether this increases air flow and performance.
Oh, yes, for definate. Anything you mount in front of the IC will cause an "air shadow" on the IC. Large spot lights would be particularly troublesome and I would expect any OE to reject any warranty claim as a result.
Lighting wise, bulbs are so 20th century!! Instead of large lights with halogen bulbs, consider getting some LED projectors and mount them in the bumper or the fog light positions. OR maybe a light bar mounted in front of the bumper. Basically, smaller lights and not in front of the IC.
@@CycloneCyd I have blue LED lights, I do to much driving in fog and dust. Love that my 200 still has old brown light in 3000k range.
My wife's car has LED low beams and fog lights 🤔🙈 it's like driving blind in fog or dust or smoke.
We both drive home once and she stopped to let me pass as couldn't see well. I was confused why till she told me... I forgot as I could see well still.
My 200 has 2 huge HID light force mounted in front of intake scoops for the intercooler.
Took them off one hot day and intercooler temps on 42c day dropped 15c after restarting even when pre temp was flat roads in the river land and post was the hill section of the start if borrosa.
Saving up and designing a mount for front of arb base rack to mount my fyerlights up with a second set of the same.
You can see roos easily double to triple the distance away as the brown light shows them up where blue led makes brown and green look the same washed out colour
Great video. Could you take the IC to a radiator shop and have it flushed?
Thanks mate. I guess you could, it wouldn't be hard to do so I'm sure someone would be willing. I haven't personally enquired though.
Cheers, Nathan.
Great video Nathan. Very informative. Just pulled the ic off my vdj79 for a look. Oily residue but not bad. Will do a clear per your video. Question. Would you use ct14 again? Or just kerosene and metho. Also, curious why you did a water wash when metho being hygroscopic would have absorbed the water, then evaporated off. Finally, did you need to remove the sensor connections off the back before cleaning.
Thanks mate. So if I was doing this again, I would only use Kerosene. This was by far the most effective method on the day.
So the reason I used water to flush out at the end was for two reason. After using the CT-14 there was a heap of soap suds remaining in the intercooler. Again, when I do it again, I wouldn't use CT-14, so this wouldn't be an issue. Further, I wanted to make sure there was no contaminants remaining within the intercooler. I didn't find this was too effective, so if I only used Kerosene, I probably wouldn't bother with the flush.
And, no, I didn't remove the sensors from the intercooler unit itself. Everything is still functioning properly months after the clean.
Cheers, Nathan.
Thanks Nathan. Appreciate the prompt reply too. Looking forward to the intercooler fan mods too.
@@haitch1980 cheers mate 👍 still working on the intercooler fan video, has taken a little longer than expected. But it is coming 👍
@@XploringOz I am looking at replacing the intercooler for either HPD or CrossCountry Ultimate. I have a problem with high egts when towing. Probably to do with having my DPchip wound up too far. Anyway, I note both these I/C's have bottom mount Fans which pull air through from top down. the alternative is top mounting the Fans as Berrima Diesel have done. I see some efficiency issues with top mounting as the fans and mountings may disrupt air flow. Obviously not the case with bottom mounting the fans. I note that Berrima Diesel run the fans full time, perhaps for that reason. sorry to hijack the thread.
Just thought it may be relevant to your investigations with fans.
@@haitch1980 I would guess that replacing the intercooler with a much larger unit, like one that you have mentioned would definitely have a much greater effect on turbo air temps then just adding fans.
I agree with the placement of the fans and this is what I am going to test out in this video. Because I will be trying to mount to fans on a budget, upgrading or replacing the intercooler is not an option. Leaving the factory intercooler where it is means that you are not able to mount the fans underneath, they're just simply isn't enough room.
I will be trying to compare the differences between the factory intercooler and factory intercooler with top mounted fans in various conditions, including high speed driving to see whether they are effective for all styles of driving.
Cheers.
I've done the same on my cruiser, before I saw your vid: you're doing it wrong, sorry.
The FIRST liquid you pour into it is lacquer thinners, not your water-based degreaser - because then the surface is water-coated hence will block the surface for access for any other non water-based liquid/hydrocarbons... like thinners is, similar like your kerosene.
Thinners however is more aggressive than kerosene (or turpentine or diesel) hence will clean best!
Flushing afterwards with Methylated Spirits (basically water-diluted alcohol) is a good idea, and I did this too, ditto for making sure the drying-out is done properly.
Nice vid, but only useful for those having installed an oil catch can!
Hi, would this cleaning method apply to an Intercooler on a truck? I’m guessing it would be. I like how you explain everything in detail, cheers.
Hey mate, I would see this working perfectly on a truck as well. I personally believe the kerosene was the most effective and you could probably get away just using this.
Appreciate the comments mate, hope you enjoy my other videos.
Thanks, Nathan.
@@XploringOz No worries Nathan cheers
Hi Nath
I would be careful using CT-!4 on an expensive aluminium intercooler. CT-14 contains Sodium Hydroxide which will attack aluminium. Check the safety data sheet for this product.
Thanks John, I appreciate the constructive criticism. Always learning, I'll be sure to look for something less corrosive.
What is the recommended or experienced Intercooler clean interval for a mixed driving experience where 30% os on all-weather roads?
Hey mate, it would depend on how often you are driving. But given the small benefit and time taken to build up contaminants, I clean my intercooler once every couple of years.
Wonder how often u have to do this
Put dual fans (kit from PWR) on, run to a manual switch. Using an auto meter dual air temp to measure effects pre and post cooler (even before install). Gauge also triggers fans at a set alarm point if I’m not paying attention. Immeasurable negative effects at highway speeds with fans off. But... HUGE difference around town, low speed off road and beach work, keeps the air flowing. If my engine could thank me, it would. Highly recommend fans
For sure. As I mentioned in the vid, I will be releasing a video building my own twin fan setup on the factory intercooler. I’ll be testing, high and low speeds, idle temps and temps under 4WD low as best I can. These types of vids take some time though. I’ll try have it out soon 👍
Cheers Nathan.
@@XploringOz I'll be waiting then. I do believe the fans are a massive upgrade to this engine but some more testing will confirm it. Thanks for your efforts and for sharing the outcome with us.
I reckon fans will also provide a reasonable increase in performance. There are a few people out there with doubts about air flow at highway speeds, but not facts to support it. I’m not sure what effect they’ll have at higher speeds, but hopefully I’ll find out 👍
XploringOz yep. I don’t do videos, so no one will believe me.
You need to measure hot and cold side of the cooler, PRE fan install and POST to prove the point though. Won’t get that on OBD. I welded in two bungs and run auto meter sensors.
Best of luck getting it sorted, and showing your results. I already have mine so I’m not bothered by the haters or the naysayers. Keep up the good work
when I changed the radiator on my p38 range rover it made sense to clean the intercooler at the same time, think I used paraffin at the time as I had it to hand, I was expecting to find quite a mess in there, but even after a couple of flushes it was pretty damn clean. I also installed a catch can.
The exhaust side of the turbo was a different matter as I found out a few weeks back 🙄
Nice, that's always good to know. Sounds like an efficient engine there!
You should also clean out the inlet and outlet pipes and hoses of the IC. the walls of the pipes will be oily and this affects the air flow.
For sure, this would also help. Just a whole lot more work 😂
Use some Nu-Calgon Special HD coil cleaner. Works great
Thanks for the tip!
I would have removed the air temp sensor. You may have knackered it with the solvents. Good video though
Good point, however fortunately this hasn't seem to be effected from this clean, but something others should take into consideration.
Cheers, Nathan.
After cleaningf, methylated spirit (alcohol) will remove any water, then use hot air to remove any remaining water,
Great video, however one problem... you flushed the intercooler while its upside down, so effectively speaking you only really cleaned the ceiling of the internals of the intercooler. would it be more beneficial to fill it with your cleaning products, then blank all entry points and then turn it upside down so you will be degreasing the area where the oil would actually be sitting?
You can, however it makes a huge mess as you can never really block the outlet/inlets 100%. Hence the shaking around trying to clean as much as possible 👍
Another thing you can use is straight petrol
Run it through a few times it'll get it squeaky clean
Yeah, I guess you could also do this. However you would want to make sure that all residue is removed from the intercooler prior to installation. Even the fumes may cause the engine to rev high on first start up.
Cheers.
One of the best things you can do to a modern diesel
For sure. I'll be switching over to a Provent Catch can soon, it will be interesting to see whether or not this makes much of a difference when compared to the current HPD can...
@@XploringOz i can confirm the provent are much better at catching oil, i wouldent have anything else on my hilux again. I had a non provent and it still blocked up my intake on my old hilux, ive checked the intake on my new one at 100k running a provent and its still virtually as clean as it was at new.
@@Ga7cun7sSUCK Good to hear. Have recently fitted my new Provent, looking forward to seeing some good results. Cheers, Nathan.
@@XploringOz good job. You wont be disapointed thats for sure. Its kind of sad for all the other manufactures because provent make a product so good no one wants anything else.
No harm in having a bit of moisture in the intercooler.
Water injection has no downsides
You won't want moisture inside the chamber though... Any moisture in they're is subject to be injected into the cylinder and diesels with their high compression figures can't tolerate moisture in the combustion chamber. Water works well outside the intercooler for quick temp reduction though.
@@XploringOz Provided you get all of standing water out, then no risk remains.
You should look into water injection (applicable for both petrol and diesel engines)
@@XploringOz normal air has water vapour; and water / meth injection has no adverse effects as a result of small amounts of H2O…
Do you think I’ll be fine to just use degreaser?
Yeah mate, that would be fine. However, my recommendation would be just using Kerosene, this was much more effective. 👍 Cheers, Nathan.
Is it normal to find oil in the intercooler? Thank you
It is with vehicles that are equiped with a CVS (Crankcase ventilation system) 👍
Nice video but the oil is actually a bad conductor heat. You said it retains the heat or something which is a bit of a weird theory. The oil just insulates the good conductor of heat- the aluminium- and stops it doing its job as a heat exchanger.
when replacing a turbo do I need to drain the intercooler?
Not required mate, can't hurt to clean it. But it's not necessary.
Cheers
What was the software you were using??
Hey mate, using Toyota Techstream. Absolutely pain to download and install, but once it's working, a very helpful tool.
Please do comparassion with intercooler sprayer
I might be able to do something like this in the future... Although it's probably not something that I would fit to my vehicle for the type of off-road touring that I do.
@@XploringOz yes thanks for proofing intercooler cleaning is not very much restoring engine power. I just bought an used Toyota Fortuner D4D 2.4 turbo diesel, i do the remap and changing the down and front pipes. before watching your video i thought i really need to clean the I/C.. Now i just adding DIY I/C sprayer.. I hope it will significant reducing the temperature because of extra boost from remap result.
@@rommyrasjid There is a good chance that intercooler sprayers will dramatically assist the intake temps. All the best with your setup!
Cheers.
Interesting results! It sure does show an improvement.
However, taking the 44°C vs. 40°C results, it's not a 10% decrease. That's because 0°C is not "zero" -- negative 273°C is. This is because -273°C is 0°K (Kelvin), which is absolute zero. Thus, the real percentage decrease is between 317°K and and 313°K, thus 4°K/317°K = 1.3%.
(and not trying to pile on and be an a-hole, but 44 to 40 isn't 10% anyhow, it's 9%)
Appreciate the correction in a polite and non-aggressive manner. As you can probably tell, I'm no scientist, but I appreciate the heads up and at least future viewers will be able to see your calculation.
Cheers, Nathan.
@@XploringOz You're welcome. Thanks for understanding my intent was to educate.
LOL the car or IC.... let along earth is never -273c 🤣
It's a 10% drop in the degrees C...
@@ausguy4385, tell me, if it went from 44°C to 0°C, would that be a 100% drop in temperature, then? If so, that would mean all of the heat was gone, and thus it couldn't get colder than that. That's clearly not true, as even you know, temperatures get colder than 0°C across many places on earth.
This is why Kelvin (or Rankine) temperatures have to be used, as they're an absolute scale, not a relative scale like Celsius (or Fahrenheit).
@@ShawnD1027 if you want to get scientific....
A intercooler will even if by magic could do the impossible would only cool to ambient temp at most...
So you missed the whole science of the video and the intercooler....
Want a more scientific measurement it would only be a percentage of cooling back to ambient.
Hi - can you do the clean and not use the water - just the degreaser, kero and meths. Don't like the water being in there, even after the hair dryer and leaving it in the sun . . I've got a Delica . .
For sure, personally having I would probably only use kero by itself. It's the most effective and is easy to clean and dry up.
@@XploringOz sweetas big feller. Thanks.
@@XploringOz kero overnight and lawn mower petrol this morning - 280k's worth of black tar diesel - really surprised by how bad it was. New turbo, catch can and now a sparkling intercooler should be good for 100 k . .
@@treborif Nice, sounds like a very thorough clean. All the best with the new components.
Ive bursted open 3 intercooler hoses in the same spot (middle, not seams) from my turbo diesel car now from normal use and considering the turbo isnt that big, ive been thinking of cleaning the intercooler to maybe reduce the pressure in those hoses? Hope anyone can comment on this as im not a mechanic but also wouldnt want to invest millions on underboost issues again.
Hey mate, so I can't see cleaning the intercooler making any difference to the boost pressure within that system. I'd be looking at the hose manufacturers or issues within the vehicles boost system as well. It won't hurt to clean it out though 👍
Do I need to clean my intercooler if I don’t have an EGR?
Your intercooler will still have oil present from the crankcase ventilation system (seperate system) however, it’s the mix of EGR and crankcase ventilation that causes a big issue. Cleaning the intercooler will slow it to operate at maximum efficiency 👍
Just as important as removing water from the core is making sure you don't have too much flammable liquid or fumes left inside like in your case the kero and the metho.
You'd be amazed what will burn in a diesel
Otherwise you may have a surprise when you start the engine.
You could have a little bit of uncontrolled fueling for a few seconds till the fuel load comes down.
At least there could be scary knocking noises .
For sure. You definitely want to make sure everything, including all the residue of those cleaning agents are well and truely removed from the intercooler prior to re-fitting.
Cheers, Nathan.
great video. But too much work for me for just 3 c difference. lol
Your warnings of excess mositure in the intercooler after cleaning are unwarranted, just send it
Well it's basically free water injection so you can run more boost until it's dry😂
Kerosene damage intercooler sensor ?
I've had no dramas so far. Looks good to me.
Is it okay to use gasoline instead?
Yes, this is another great cleaning agent 👍
TBH it was pretty clean in there
It wasn't too bad, but it looks like it still made a little difference 👍
Nice job and nice results demonstrating the benefit. On a normal saloon car I suggest cleaning the IC every 50,000 miles. More often if it's a diesel engine (40 or even 30 000 miles).
You might be interested to learn where this oily residue comes from. It's a result of blowby gasses and oil mist being recycled through the PCV system to be burned. You can virtually eliminate this oil by using a good catch can (which must be properly installed, most DIY jobs I've seen are not). If you use a cheap catch can use two in series.
Now that you have seen the oil residue in the IC, have you considered the turbo compressor and the throttle body? I've got a playlist with some info in. It's aimed at car owners but is relevant to 4x4s too.

Thanks mate, glad you enjoyed the video.
I am definitely keeping an eye on this system and will clean out periodically 👍 I do also have a Provent 200 catch can, which works well, however isn't perfect.
Thanks mate, I'll definitely check out your videos.
Cheers, Nathan.
If I install a catch can on my turbo car, will the remaining oil residue in the intake manifold just clear itself out over time or will it cook onto things since the catch can will prevent new oil residue from coating things?
Where is the before cleaning, hair dryer temperature test for comparison?
Unfortunately something that wasn't completed in this video.
@@XploringOz As liquid is more conductive to temperature variation than aluminium, perhaps the cooler actually works better with an oil coating inside, and is designed that way. Just periodically draining excess oil out may be sufficient maintenance. Now we will never know.
@@tg5834 Although technically possible, I don't think this is the case. My on-road tests would suggest otherwise and Toyota have designed the CVS to filter into the intake due to emissions restrictions, not performance benefits. I'm sure they would consider more liquid (oil) if this were to provide a benefit.
Cheers.
me I used acetone ie nail polish remover as it leaves nothing behind to damage the engine ok ..................
Thanks for sharing mate, another great idea that I might try out in the future.
Cheers, Nathan.
Why does it have to be completely dry? I don’t see have that little bit of water is going to damage anything, are you worrying about hydrolocking or what?
What if the concoction of chemicals caused an explosion
I'm fairly confident that it wouldn't in these circumstances.
You do realise that you didnt use enough in terms of volume to clean the channels on the top half and its not as if you can flip it over either
kero - best
Agreed 👍
Could have slipped in an EGR plate with 10mm hole while that intercooler was off.
Yeah, could have, but holding off on that for a little longer. Will be doing some more research in the future regarding this. Cheers.
@@XploringOz Word on the street is that it's best with the plate with the hole in it, smoother engine shutdown with that plate and much less E.G.R soot ingested, technically still an E.G.R system you can say to the magistrate. Rumour has it the full block off plate can throw up an engine fault code but that's probably a baseless rumour spread by magistrates with vested interests. Exhaust gas temps up a little but that would be due to more oxygen in the air/fuel mix, slightly better fuel economy, better low end throttle response and much less carbon into the motor & soot clogging your intake system.... So I am told.
@@dustyfarmer Would definitely be an interesting one to try. The only thing that gets me a little bit is that the blanking plate with the hole is still letting the gas recirculate, so eventually your going to end up in the same situation.
I reckon it would definitely help with the low end and low throttle input response.
I heard you an also limit the EGR's function via the ECU, not able to turn it off, however lower its usage.
@@XploringOz I think with the reduced size hole it also lowers the vacuum on the E.G.R so you don't pull anywhere near as much soot. E.G.R only operates around idle & just above I think. I'm doing the twin intercooler fan upgrade too, I'll take a look in the pipe when I have the intercooler off.
@@dustyfarmer That's right, the EGR is only circulating during idle and low throttle input. The circulation is stopped for full throttle to allow for maximum power and efficiency.
I'm just about to do some testing with the twin intercooler fan modification. Hopefully I'll have a video up in the next month or so with my findings. Will definitely be an interesting one to see the compromises.
if that was a Triton intercooler you would be pouring out crud that resembles Tar. They are the biggest oil spewers in the known universe. Honestly you would need triple the cleaning fluid & it would still be putrid when you have finished.Also mentholated spirits doesn't really dissolve oil but it will mix with any water that is still in there and get it out.
For sure, there are some models and manufactures out there that produce significantly more oil and EGR residue than others!
Just use petrol to clean.
12:20 lol :D wtf dude why would you do this?
Every little bit helps 👍
@@XploringOz well actually I recpect that upon some thinking. Cheers! Details matter.
and after all this, replace with a decent FMIC and ditch the stocker.
yes, a good option. But pricey 💰
hopefully you cleaned all the pipes when you had the intercooler off
Not in this case, however the length of pipe from the recirculating gases intake and the intercooler and again from the intercooler to the intake are minimal and would have little bearing on these results.
XploringOz I was talking about the outside of the pipes so it looks as shiny as the rest of the engine bay!
Haha, yeah. I try and keep the engine clean. If you’ve watched my engine bay clean video you’ll see how far I go 👍
Nothing is going to happen if theres water going in the intake. it'll actually probably clean the inside, lol
Not quite sure what you mean there mate?
