I have a Lexus CT, which is the same engine system as Prius. I was depressed with the engine vibration for the last couple of years. I brought the car to multiple dealers, and they replaced plugs, battery, tires, etc, charging me many $k. Then I found this video. I followed the instructions, and the vibration is gone. You saved my life!!
IMO nearly all regular service operations are simply and easily accomplished by the owner if so inspired. Mine needs an EGR cleaning right now, after 255k miles. Not too shabby !
@@BillyDenton-nx3oycleaning the EGR cooler itself is absolutely not something I would recommend an inexperienced person to attempt Especially without the correct tools, it’s very hard to get to some of the nuts without the right tools and small nimble hands
@@BillyDenton-nx3oy Is this the first time? I just got a 2013 Prius that has 170k miles and it drives great with no issues whatsoever. Do i need to do this now?

Mine is a quarter of millions miles, and is running like the first days, just oil changes, transmission and filters. Toyota Prius 2012 second generation.
@@mizudu4306you should really clean your Egr system. There is zero chance that it’s not clogged up. That being said, I’m glad you are enjoying your pwagon! Love mine
You have to also pull your intake and clean the 4 egr inlet holes that flow into the intake really good... You can instal brand new egr valve and cooler but if those 4 holes are blocked car will still not run correct
Just did it on my 2010 Prius (150K+ miles). A few notes: 1. There's no real need to unclip the plastic bracket, just move it out of the way. 2. Absolutely no need for a bronze brush and the drill. Blast that pipe with throttle body / carb cleaner, and it's shiny as new. 3. Wrap a piece of lint free cloth on a stick and saturate it with carb cleaner. Wipe the corresponding manifold & valve holes with it, rinsing with a stream of carb cleaner after each insertion. Basically same technique as removing the ear wax: don't push it in )
You probably won't read this since it's been 5 years but the bottle of carb cleaner I got said it's not recommended for Fuel injected vehicles...and unless I'm mistaken, the prius is a fuel injected car.
@Raj Nadar The instruction is for using it during running conditions. We use the carb cleaners offline so really it doesn't matter. Gumout brand is best it evaporates in 10 minutes. Gunk brand takes 4-5 hours to evaporate. For cooler and egr use 1 full bottle of Gumout.
Thanks for doing this video. Dealer wanted over $300 (estimate), followed your video and did it myself. Note: didn't remove the plastic tab next to left port/tube, just pushed it aside. Vehicle seems to run better after it was done. Thanks again. cr from Florida
Hey I’m bringing this thread back to life lol, but I have a check engine light for a EGR as well. Did you just clean the pipe and it went away or would I need to take out the whole assembly to clean out?
@@davidwollpert5276 gOOD news friend, i bought mine 2 weeks ago 2012 plug in with 204.000 m, the older guy took good care of it, he documented every record from toyota dealership, clean title , no accidents. i bought it for $5.400, do you think its a good price ? i was reading all these nightmares about head gaskets. But to be honest with i see a lot of people doesn't have this problem, and they around 300 k mark. You kind of made me feel better when you sad its 240 k and its running great, can you give me any advice ??? since im new to Prius. p.s. Im in love with this little car ) coming of 2005 lexus ex 330. thank you in advance
@@yevlyan4060 that’s an OK price. Have you cleaned the EGR pipe, like in this video. That’s related to head gasket problems. I would definitely do it if I were you. It’s quite easy.
@@davidwollpert5276 no I did not . But I will this following week. Pipe is easy, I was thinking about EGR coolant or something like this, this one is tricky, but hopefully I'll do this. My engine seems fine, coolant level stays on level. I'm in New York and when I start engine, for a few seconds I do have a little bit white smoke, but this one is clear and a little bit. I think its because its cold and humid. My friend brand new car 2023 lexus rx 350 does same with even more white clear smoke. So I think its normal.
Thank you so very much! I followed your video step by step and it resolved the issue and the engine warning light is now off and saved me time and $$. You're awesome!
Really helpful video, I had a noisy engine and juddering at idle on a Lexus CT (same engine). I did find in the end it was the spring on top of the EGR valve that was jammed open causing the problem, lubricated it and gave it a work up and down to free it off. But did give the pipe in the video a clean at the same time I had plenty of crap inside also.
I'm glad you have all these egr cleaning videos. I just bought a 2012 with 186k on it and I don't think the EGR has been cleaned out. Would be a very good idea to clean the cooler too while I'm at it. I'll probably soak it all in the sun to try and get it broken up.
@@NutzAboutBolts Yeah I was thinking about using something similar. Instead of leaving it overnight, I figured a decent az afternoon would do a good job of baking it
I did this on my 2010 Prius with 116k miles and I removed the intake manifold. I was glad I did because all 4 runners were gross. I highly recommend taking off the intake manifold. It wasn't that hard to do. I also installed a new PCV valve with it off and an oil catch can to keep it cleaner down the road.
I went beyond and took out the entire EGR assembly/cooler to clean. I used an extra reach 12 mm racheting wrench for the three nuts in the back and slowly reached the 4th HIDDEN 12 mm nut underneath the EGR cooler (with another tool). Used a Torx E8 socket for the two long bolts in the back of EGR cooler. Good video NAB!
Unfortunately, that won't clear a P0401 code, in most cases. However, it is helpful to clean the pipe out. Here's what I did to correct the restricted flow problem. When you pull he plastic cover off of the top of the engine, you'll see the round (nipple-like) cover to the EGR solenoid. Remove the two Phillips head screws and pull the cover off, no need to disconnect the wiring harness. Unscrew the cylindrical magnet with the bearing on top. The shaft will be exposed. If you put a washer over the shaft, just covering the round disk, then screw the magnet back on, this increases the throw of the plunger, and restores the flow. If you look inside the cover, you'll see a small plastic ridge, it's covered with grease. Look closely and you'll see that it's worn down and not letting the valve open like it should, or used to. This is what fixed mine, and I just wanted to save headaches for others. It will take three run cycles to clear the code. You just saved some cash...HAPPY DANCE ! ! !
If you could make a video explaining what you did and list links to the parts used in the description of that video (just like this video does), I would greatly appreciate it!
Thanks for the video. Did this on mine with 90k. It def needed it. A few notes for others. I was unable to get the mas connector off, but there's enough slack to move it out of the way safely. Second i didnt have a small opened end metic wrench set. But i was able to get my 1/4 10mm socket in between the harness wires to remove the front 2 bolts holding the pipe
2012 Prius with 295k, Toyota dealership quoted me $1700 for this along with cleaning the intake manifold, throttle body, and replacing spark plugs and gas cap. I’ll be doing it myself.
I haven't done this job, but it looks like if you passed a rope through the pipe/tube and pulled it back and forth with solvent on it, it could clean the middle of the pipe that you couldn't get to,
Next time try letting the pipe soak in parts cleaner for a while, if you're not in a hury. Also, use some vinyl gloves or something. Those chemicals are harsh. Good job.
Tips to PREVENT HEAD GASKET FAILURE: 231K - 2013 Prius. Just had head gasket replaced for $1,500. Could of prevented it if I cleaned/replaced EGR cooler around my second run of 80K or 90K miles? Maybe it happened to me a bit sooner because I cleaned my EGR cooler out about 90% +\- at 130k miles, + 1000 miles/week, 50K/yr. and maybe because of potentially more cold/heat cycles on the head gasket. Lots of people highly recommend 3rd gen prius owners clean or replace EGR cooler AT or BEFORE you hit every 100K miles. EGR cooler $178 new on ebay, $300 at toyota, part 25601-37010. Clean EGR pipe and valve with the intake manifold/throttle body. Replace PCV valve, optional oil catch can. X At 230K miles my EGR cooler was completely blocked up with soot (previous cleaning at 130K). My symptoms were brief misfire on #2 couple times every 100 miles and slow engine coolant leak into the engine. #2 spark plug and #2 set of 4 valves were pretty dirty. Head gasket and cylinder head was replaced with refurbished one. (6,000/3month warranty). Car runs great so far. 4th Gen Prius has improved this problem.
WOW, this is EXACTLY my current issue and I'm at about 209K miles. My mechanic wasn't sure exactly what the problem is (not a lot of Prius' here in the mountains) and now I have something to bring to him. How much did the EGR cooler cost you? Thanks!
@@ashleyryder6764 Hi. yes I think all of 3rd gen prius have this issue above the first 120k miles and every 100k +/-. Blame toyota I guess for not creating a better EGR flow system. goodbye 1500$ :-0 I knew of the problem before i bought the prius when researching and it still happened to me, i was even planning on cleaning it before it happened. As I said in my first post it cost me 170$ on ebay but that is out of country and shipping time consider. search the part # or pay toyota $300 w/tax or clean the part very good and replace or buy the part and keep your old cooler to have it cleaned for the next 100k miles cleaning. clean cooler, pipe, valve, intake, replace pcv valve, i have not put an oil catch can in but that is optional and may help. I followed youtuber "nutzaboutbolts" and did everything myself. Good luck.
@@ashleyryder6764 probably double check with trusted mechanic if they agree but if you have coolant loss and the coolant doesn't seem to be leaking anywhere except probably into the engine with the couple of misfires every hundred miles more or less than probably is failing head gasket especially at that mileage.
What made you clean this EGR pipe, engine is running poorly or some warning lights went on, or bc you have high mileage on the engine then decided to clean?
I have the same question. My ct200h does rattle here and there on a cold start. Not like crazy though... Did do crazy rattle few time over the three years maybe 3 /4 times. Mileage is around 60k to 70k.
after cleaning egr valve, cooler, pipe and intake manifold, gas mileage on my 2013 Auris TS dramatically increased. Especially egr cooler was full of black carbon that took several degreaser baths to wash away.
Great video; just bought a '13 with 67K miles. I will look into doing this. I like your other videos also. Already changed the CVT fluid to synthetic recommended by PriusChat. The original stuff looked dirty although the dealer said wait until 100K miles. Why wait? Preventative maintenance is the key to long life. The car seems to shift a bit better also. Keep up the good work!
On my 2010 prius when the battery is low and at low speed acceleration (10-15%) there is a rattling sound. This only occurs when the battery is low and the engine is running to charge the battery. I read online that this could be due to a dirty EGR. What do you think? Dealer says its a bad hybrid battery and to trade the car in. I really don't think it's the actual battery.
I've never experience that type of problem before, if there's no check engine light, I would check if there's anything loose... you can also post your questions on PriusChat to see if anyone else has experience the same thing you're having.
This is exactly the problem I am experiencing now, with check engine light on, and I just brought my car to the dealer today and they diagnosed it as EGR valve. The solution they suggested was replacing the entire EGR kit, at a mere $900.
1compaqedr8 did you find a solution to this problem? I had the EGR and EGR cooler replaced and still experience the same problem. The car runs absolutely perfect unless it is at low battery. It rectifies itself after charge to 3 bars. Thanks for all your help.
I'm thinking this might be the best first step to give an indication whether the rest of the EGR system and manifold needs cleaning. If you find that the pipe is relatively clean and maybe just a little dirty, would that be an indication that further cleaning of the system is not necessary at that time?
@@TheToufikzeidan Hello there. I have the same issue could you help me?

(backround info. my water pump just went bad about a month ago and this happen roughly around the same time. 147k. don't know if it's related! not losing coolant though. levels are good) A couple videos were saying that means it's 100% a bad head gasket. But is that true? Or should I try the ERG, and also replacing the plugs / coils (they need to be replaced anyway). I do find it funny that ALL the cylinders are showing a misfire all at once...
@@levijessegonzalez3629 you need to clean the EGR. There are bunch of videos on UA-cam showing how. It’s because the intake is clogged with carbon. I used a screw driver wrapped in a cloth with some WD40 and cleaned it. Never had an issue since.
To clarify the egr system brings combustion gases into a cooler, then through an egr valve (controllled by load) then into the intake. Usualy problems associated with shaking and running poorly arw because the egr valve is not functioning properly. A dirty pipe and intake is the result, not the problem. A better idea would be to start at the block and clean the cooler if need be, then the valve itself. If the valve is too dirty it stays open and dumps air into the intake at the wrong time, and will gunk up the intake, making the car shake at low load or idle.
Thanks for this excellent video! I am going to try cleaning the EGR as you did here. I drive a 2013 Prius w 197,000 miles. I'm wondering if there is any chance a fuel filter can cause the engine to idle roughly? I don't know if my fuel filter has ever been replaced and I used some old gas recently. I don't see much about people replacing fuel filters on Priuses.
Follow the intake manifold cleaning, if you follow that video, you can remove and clean the EGR at the same time. You can also replace the pcv as well since it’s underneath the intake manifold. Also install a catch can if you can.
Hey NAB, thank you for your videos. Last night my 2010 Prius started sputtering at low RPM. I also noticed a sulfur smell. I had never seen that before. The temperature is getting colder in Chicago too. When I drive at higher speeds, it drives normal. Any idea? No engine check light.
Great video. I just did mine. Forgot to plug electric connector into egr valve completely now I have an archived p0403. Anyone know how to clear it? Thanks.
@@NutzAboutBolts I used a scanner to clear the code however when recheck for dtc I still get the p0403 however it’s “archived”. It’s a pdtc if that matters.
@@Uncommonsense999 not sure, but usually it’ll have a memory of it for future reading on the scanner. I wouldn’t be worried since it was an accident and not an actual problem on the car.
Hi NutzAboutBolts, I watched a fews of your videos and read your maintain guide on priuschat; however, I have not seen anyone mention that the high voltage battery was disconnected before fixing. I assume that’s a must, correct?
Better wear eye protection when spraying brake cleaner. Get some in your eyes and you will holler out loud. Gloves to for spraying in your hand. OR, a better way to clean that pipe is soak it in Diesel. WAY less fumes and costs much less than canned death. Keep a gallon of Diesel in the garage to clean dirty filthy parts just like yours in the video.
I have a 2014 prius i have a p3190 (low engine performance). Driving me crazy.. Car dies and all the lights come on. After i let it sit for a hour it starts. Tried cleaning maf sensor n throttle body so far. My 12v battery is at 12.2v
@@NutzAboutBolts cleaned egr cleaned manifold. Maf sensor + Fuel pump module and same problem. Not it starts for 10 seconds low rpm then it dies and you get all the warning lights
@senan Fouad, my 2013 camry had a same problem. Two shops gave up. So I took it to toyota dealer. They try new fuel pump, new computer, chasing the cables kept my car for 3 weeks and then they told me I need whole new wiring. Told me about 3 grand. I told them no way. I found a local Repair shop dealing with the taxi and uber drivers. They told me no big deal, next day day called me car is fixed. It was relay pack in the fuse box underneath the hood that controls the fuel pump and computers. Cost me under $200. I hope your car is taking cared.
I loved your videos and have certainly bought off your Amazon referral links. I am wondering if you would have insight on this… I recently did the EGR clean out, the pipe, the ugh radiator cooler looking thing, and the EGR valve too. Everything reassembled and car runs like new. So much more power. And check engine light never came back on. But now I am smelling exhaust when I am driving close to a truck or whatever. Doesn’t matter if my car is on recirculating air or fresh air, it comes in. But if I am not driving next to a smelly truck, I don’t get smell. So smell is not coming from the Prius. Any idea what step I could have missed in the reassembly that could have caused the recirculating air to still be pulling in outside air?
Have you checked your cabin air filter? I noticed my vent closing for the outside doesn’t fully closed outside air but does have some air come in, I guess that’s normal to have a little bit of outside air coming in even if the recirculating vent are closed from outside air.
@@NutzAboutBolts I was gonna check that it may be due to change anyways. But just strange that I didn’t touch the cabin air filter with the EGR process. I don’t even know what to search for. But could the flap be stuck on outside air coming in? It definitely wasn’t letting that much outside exhaust in before.
@@entao6425 over time the cabin filter can get dirty from debris outside, check the outside air vent on the passenger side to see if it’s covered in dirt, dust or leaves and check the cabin filter. I myself haven’t experience any exhaust fumes or smell after this service… try having the engine hood open and vehicle on to see if you can mimic the smell in the engine bay.

Yep😂.. I have noise like 9 months. Changed ignition coils spark plugs still noise. I saw this video and said, "What EGR is. i went to my car opened EGR found it 100% clogged cleaned it no noise anymore .
Hey, I just had someone replace my spark plugs on a 2010 (side hustle mechanic) I was experiencing a 5mph MPG drop since Aug and the car has 160K and to my knowledge plugs were never changed. In any case he replaced them, the ones he took out were def in there for awhile but were not too bad looking. In any case he also check maf sensor and lightly used the tip of a flat head screw driver to scape a thin layer of carbon off. I have drive now for 2 weeks and no difference in mpg. I wanted to get the egr pipes cleaned. so can that be done without removing the windshied shroud and wiper motor assembly. I would like to get to bottom of it and your vid tells me you know a thing ot two
@@NutzAboutBolts Thanks for quick reply. Is just cleaning that pipe enough to perform egr maintenance and can that be a culprit for lower MPG. My car threw a P0304 code about 3 weeks ago I had it reset after the sparks were replaced and the mechanic switched coil 2 and 4 so far the code has not resurfaced but the mpgs are still down about 5 from 45 average. I know it has 160K but hoping to get at least 250-300k out of it
After cleaning I experienced misfiring. Disconnected and reconnected coil one now it was running well for a week and now I have four codes after a week. I do get a rattle at times I wish I knew of this process before 150k. Codes are p0351 p0401 p3190 p0a0f c1241. I don’t really want to pay the dealer to fix but I think my next best step is to check coil one.
so i just did everything you did, luckily my egr pipe and the intake inlet werent completely clogged. i went ahead and took it a step further and removed the intake manifold to clean it out. 3 of the little ports inside were completely clogged up. i cleaned them out and put everything back together. when i went to start the car, it started fine, then the engine kicked on for about 5 seconds. it started to increase rpm and then shut off. check engine light and hybrid light came on. i'm waiting to get a scanner to check the code. any clue in the meantime what it could be? i made sure everything was connected and tight. possible gasket seal leak?
did all the connectors got plugged back in place? never heard of it throwing codes when you removed the intake to clean it. I've read on the PriusChat forum that people remove the intake manifold and EGR and pipes to clean the oil deposits and never had any issues. I would get it scan and see what the code reads before proceeding forward.
Is this job even worth doing if you dont clean the EGR cooler, valve, and intake manifold as well? I presume if the pipe is clogged the other elements are clogged?
Hi NutzAboutBolts, please excuse me for a rather back-to-basics question here: what would the effect be of not cleaning this EGR pipe and its associated ports? What aspect of engine performance would this affect, and by how much, in general, would you say, in your experience?
2010 Prius egr information CRITICAL! If you have e code for restricted egr flow, here's what to do. Seriously, I've done this in parking lots in under two minutes! Pop off the plastic engine cover, and see the egr valve on the right side. Unclip the wire harness, remove the two Phillips screws, and pull off the cover. Rotate the cylinder counter-clockwise and pull it off. Now, find a lock-washer that fits over the shaft, and clears the spring. Slide it onto the shaft and reassemble. Here's why, if you want to know. There's a plastic hub that gets worn down inside of the cylinder and, over time, won't engage the plunger enough to recirculate the exhaust gases. The lock-washer acts as a shim and gets it working again. Allow 5 or so engine cycles (cool to warm, and back again) for the light to reset. Now, punch it! It runs WAY better! Now, use ashtrays, don't beep your car to lock it, and smile more!
my dear friend all the knocking problem and noice problem I could remove it. Simple solution is that don't even open the whole EGR kit. just open the two screws of EGR socket and check is your EGR moving up and down. if it is not then all the problem in GEN 3 Prius is due to this EGR. I can send you detailed solution trust me I was banging my head to all the dealers and eventually I could diagnose and rectify the problem. now my Prius is running like a queen.
Hey Mind Right Life Right, can you help a bro out? The cold season is starting and my GEN 3 did the "knock" yesterday, haha I wanna try out this, can you send me the detailed solution?
Bro just open the two screws which will bring the electrical circuit out and check that is the valve going up and down. If it is then your dash board shall have 401 fault code. If not then the Egr valve needs to get cleaned and it needs to move freely up and down. Let me know if you were able to..

Got P0300 for first time ever, along with other cyl codes, this last time. Something else keeps causing the cylinders to repetitively misfire. What is it? Nobody seems to be able to pinpoint the exact cause.
You can recharge with pure refrigerant without any additive, no oil. Just pure can, smallest can, and completely new charger hose. I would buy new 3 lines hose with pressure meter on it that can be connected to high and low pressure lines. So, you are not overcharge it. 3 line hoses also good to diagnose what the real problems, compressor, condenser, evaporator, or just low refrigreant. Just recharge it and do not use any oil unless it is ND11 (non-conductive oil). PAG oil for other cars will short your 110V AC compressor and destroy it.

@@davidwollpert5276 gOOD news friend, i bought mine 2 weeks ago 2012 plug in with 204.000 m, the older guy took good care of it, he documented every record from toyota dealership, clean title , no accidents. i bought it for $5.400, do you think its a good price ? i was reading all these nightmares about head gaskets. But to be honest with i see a lot of people doesn't have this problem, and they around 300 k mark. You kind of made me feel better when you sad its 240 k and its running great, can you give me any advice ??? since im new to Prius. p.s. Im in love with this little car ) coming of 2005 lexus ex 330. thank you in advance
@@yevlyan4060 that’s an OK price. Have you cleaned the EGR pipe, like in this video. That’s related to head gasket problems. I would definitely do it if I were you. It’s quite easy.
@@davidwollpert5276 no I did not . But I will this following week. Pipe is easy, I was thinking about EGR coolant or something like this, this one is tricky, but hopefully I'll do this. My engine seems fine, coolant level stays on level. I'm in New York and when I start engine, for a few seconds I do have a little bit white smoke, but this one is clear and a little bit. I think its because its cold and humid. My friend brand new car 2023 lexus rx 350 does same with even more white clear smoke. So I think its normal.
Thank you so very much! I followed your video step by step and it resolved the issue and the engine warning light is now off and saved me time and $$. You're awesome!
What was the engine warning code for this?
Really helpful video, I had a noisy engine and juddering at idle on a Lexus CT (same engine). I did find in the end it was the spring on top of the EGR valve that was jammed open causing the problem, lubricated it and gave it a work up and down to free it off. But did give the pipe in the video a clean at the same time I had plenty of crap inside also.
So after your Lexus ct ran a lot smoother at idle? My ct is juddering at idle too.
@@matthewdoyle8644 Yes, it ran perfectly after I freed off the sticking EGR valve.
I'm glad you have all these egr cleaning videos. I just bought a 2012 with 186k on it and I don't think the EGR has been cleaned out. Would be a very good idea to clean the cooler too while I'm at it. I'll probably soak it all in the sun to try and get it broken up.
People use oven clean chemical and soaking it over night to break down the carbon build up in the cooler and egr pipe.
@@NutzAboutBolts Yeah I was thinking about using something similar. Instead of leaving it overnight, I figured a decent az afternoon would do a good job of baking it
I did this on my 2010 Prius with 116k miles and I removed the intake manifold. I was glad I did because all 4 runners were gross. I highly recommend taking off the intake manifold. It wasn't that hard to do. I also installed a new PCV valve with it off and an oil catch can to keep it cleaner down the road.
Catch can on a prius? That awesome and interesting at the same time. 😂👌😎 What catch can do you installed?
Amazing,this dude definitely deserved millions of subscriber.god bless you Bro.
I went beyond and took out the entire EGR assembly/cooler to clean. I used an extra reach 12 mm racheting wrench for the three nuts in the back and slowly reached the 4th HIDDEN 12 mm nut underneath the EGR cooler (with another tool). Used a Torx E8 socket for the two long bolts in the back of EGR cooler. Good video NAB!
I'm doing all this over the next few days. Too much for me to handle in one sitting.
Unfortunately, that won't clear a P0401 code, in most cases. However, it is helpful to clean the pipe out. Here's what I did to correct the restricted flow problem.
When you pull he plastic cover off of the top of the engine, you'll see the round (nipple-like) cover to the EGR solenoid. Remove the two Phillips head screws and pull the cover off, no need to disconnect the wiring harness. Unscrew the cylindrical magnet with the bearing on top. The shaft will be exposed. If you put a washer over the shaft, just covering the round disk, then screw the magnet back on, this increases the throw of the plunger, and restores the flow.
If you look inside the cover, you'll see a small plastic ridge, it's covered with grease. Look closely and you'll see that it's worn down and not letting the valve open like it should, or used to. This is what fixed mine, and I just wanted to save headaches for others.
It will take three run cycles to clear the code. You just saved some cash...HAPPY DANCE ! ! !
If you could make a video explaining what you did and list links to the parts used in the description of that video (just like this video does), I would greatly appreciate it!
My 2010 prius just coded p0401, and it looks as if it's out of warranty for a new egr kit from toyota. Is your fix keeping your car code-free still..?
Thanks for the video. Did this on mine with 90k. It def needed it. A few notes for others. I was unable to get the mas connector off, but there's enough slack to move it out of the way safely. Second i didnt have a small opened end metic wrench set. But i was able to get my 1/4 10mm socket in between the harness wires to remove the front 2 bolts holding the pipe
2012 Prius with 295k, Toyota dealership quoted me $1700 for this along with cleaning the intake manifold, throttle body, and replacing spark plugs and gas cap. I’ll be doing it myself.
I haven't done this job, but it looks like if you passed a rope through the pipe/tube and pulled it back and forth with solvent on it, it could clean the middle of the pipe that you couldn't get to,
Next time try letting the pipe soak in parts cleaner for a while, if you're not in a hury. Also, use some vinyl gloves or something. Those chemicals are harsh. Good job.
Great video! Thanks I owe you a very large beer when you are in San Diego
haha thanks.
I love your prius videos. You are helping me out so much. Thanks!
Hey thanks so much for this video. I hope that you become extreamly popular on youtube
Tips to PREVENT HEAD GASKET FAILURE:
231K - 2013 Prius. Just had head gasket replaced for $1,500.
Could of prevented it if I cleaned/replaced EGR cooler around my second run of 80K or 90K miles?
Maybe it happened to me a bit sooner because I cleaned my EGR cooler out about 90% +\- at 130k miles, + 1000 miles/week, 50K/yr. and maybe because of potentially more cold/heat cycles on the head gasket.
Lots of people highly recommend 3rd gen prius owners clean or replace EGR cooler AT or BEFORE you hit every 100K miles.
EGR cooler $178 new on ebay, $300 at toyota, part 25601-37010. Clean EGR pipe and valve with the intake manifold/throttle body. Replace PCV valve, optional oil catch can.
X
At 230K miles my EGR cooler was completely blocked up with soot (previous cleaning at 130K). My symptoms were brief misfire on #2 couple times every 100 miles and slow engine coolant leak into the engine. #2 spark plug and #2 set of 4 valves were pretty dirty. Head gasket and cylinder head was replaced with refurbished one. (6,000/3month
warranty). Car runs great so far. 4th Gen Prius has improved this problem.
WOW, this is EXACTLY my current issue and I'm at about 209K miles. My mechanic wasn't sure exactly what the problem is (not a lot of Prius' here in the mountains) and now I have something to bring to him. How much did the EGR cooler cost you? Thanks!
@@ashleyryder6764 Hi. yes I think all of 3rd gen prius have this issue above the first 120k miles and every 100k +/-. Blame toyota I guess for not creating a better EGR flow system. goodbye 1500$ :-0 I knew of the problem before i bought the prius when researching and it still happened to me, i was even planning on cleaning it before it happened.
As I said in my first post it cost me 170$ on ebay but that is out of country and shipping time consider. search the part # or pay toyota $300 w/tax or clean the part very good and replace or buy the part and keep your old cooler to have it cleaned for the next 100k miles cleaning. clean cooler, pipe, valve, intake, replace pcv valve, i have not put an oil catch can in but that is optional and may help. I followed youtuber "nutzaboutbolts" and did everything myself. Good luck.
@@ashleyryder6764 probably double check with trusted mechanic if they agree but if you have coolant loss and the coolant doesn't seem to be leaking anywhere except probably into the engine with the couple of misfires every hundred miles more or less than probably is failing head gasket especially at that mileage.
Thanks! Engine light went off a day later after watching your video, great instructions!
You are supposed to remove the intake and clean the 4 small egr holes and install a catch can on you pcv to catch all the oil blow by...
What made you clean this EGR pipe, engine is running poorly or some warning lights went on, or bc you have high mileage on the engine then decided to clean?
Probably because gen 3 Prius are known for gasket blowing up around 140k miles
@@magleeventures2246 so, cleaning EGR valve will prevent head gasket in the future?
I have the same question. My ct200h does rattle here and there on a cold start. Not like crazy though... Did do crazy rattle few time over the three years maybe 3 /4 times. Mileage is around 60k to 70k.
after cleaning egr valve, cooler, pipe and intake manifold, gas mileage on my 2013 Auris TS dramatically increased. Especially egr cooler was full of black carbon that took several degreaser baths to wash away.
Great video; just bought a '13 with 67K miles. I will look into doing this. I like your other videos also. Already changed the CVT fluid to synthetic recommended by PriusChat. The original stuff looked dirty although the dealer said wait until 100K miles. Why wait? Preventative maintenance is the key to long life. The car seems to shift a bit better also. Keep up the good work!
garth locklin the car does not shift?
This is the funniest comment.
Will doing this , will is stop my 2012 prius engine from sounding like it wants to blow up?
What size are the bolts that hold the pipe on? at 6:07 Im missing the lower one
On my 2010 prius when the battery is low and at low speed acceleration (10-15%) there is a rattling sound. This only occurs when the battery is low and the engine is running to charge the battery. I read online that this could be due to a dirty EGR. What do you think? Dealer says its a bad hybrid battery and to trade the car in. I really don't think it's the actual battery.
I've never experience that type of problem before, if there's no check engine light, I would check if there's anything loose... you can also post your questions on PriusChat to see if anyone else has experience the same thing you're having.
This is exactly the problem I am experiencing now, with check engine light on, and I just brought my car to the dealer today and they diagnosed it as EGR valve. The solution they suggested was replacing the entire EGR kit, at a mere $900.
1compaqedr8 did you find a solution to this problem? I had the EGR and EGR cooler replaced and still experience the same problem. The car runs absolutely perfect unless it is at low battery. It rectifies itself after charge to 3 bars. Thanks for all your help.
Try cleaning the hybrid battery could be dirty
TIMOTHY ANDERSON I have the same problem. Maybe you found out What really happen? Thanks
Great video! I found your explanation and video easy to follow. Now I just need to find the time to clean out my EGR pipe!
lol nice! glad we could help
I'm thinking this might be the best first step to give an indication whether the rest of the EGR system and manifold needs cleaning. If you find that the pipe is relatively clean and maybe just a little dirty, would that be an indication that further cleaning of the system is not necessary at that time?

A couple videos were saying that means it's 100% a bad head gasket. But is that true? Or should I try the ERG, and also replacing the plugs / coils (they need to be replaced anyway).
I do find it funny that ALL the cylinders are showing a misfire all at once...
@@levijessegonzalez3629 you need to clean the EGR. There are bunch of videos on UA-cam showing how. It’s because the intake is clogged with carbon. I used a screw driver wrapped in a cloth with some WD40 and cleaned it. Never had an issue since.

Thanks! Man, military instructions make me fall asleep, I’m not sure it’s a good thing 😂😂😂
Anyone try running prius without EGR pipes?
did mine at 56K it was dirty. I cleaned the manifold as well. easy.
The proper way to clean is to take manifold out and clean 4 ports which are normally clogged.
To clarify the egr system brings combustion gases into a cooler, then through an egr valve (controllled by load) then into the intake. Usualy problems associated with shaking and running poorly arw because the egr valve is not functioning properly. A dirty pipe and intake is the result, not the problem. A better idea would be to start at the block and clean the cooler if need be, then the valve itself. If the valve is too dirty it stays open and dumps air into the intake at the wrong time, and will gunk up the intake, making the car shake at low load or idle.
Thanks for this excellent video! I am going to try cleaning the EGR as you did here. I drive a 2013 Prius w 197,000 miles. I'm wondering if there is any chance a fuel filter can cause the engine to idle roughly? I don't know if my fuel filter has ever been replaced and I used some old gas recently. I don't see much about people replacing fuel filters on Priuses.
Follow the intake manifold cleaning, if you follow that video, you can remove and clean the EGR at the same time. You can also replace the pcv as well since it’s underneath the intake manifold. Also install a catch can if you can.
So is this preventative maintenance then?
Do this to avoid future headaches?
Steve M preventive maintenance and also prevents engine knocks from a dirty egr system.
Awesome video. Does the Rav4 Hybrid require the same procedure? If so, please post a video showing the location.
I’m sure it does, but we currently don’t have a rav4 hybrid to demonstrate. 😅

😅😅
Did anyone’s Prius shake at start up for approx 10sec prior to this???
Hi NutzAboutBolts, I watched a fews of your videos and read your maintain guide on priuschat; however, I have not seen anyone mention that the high voltage battery was disconnected before fixing. I assume that’s a must, correct?
You’re not messing with any high voltage parts, so it’s not necessary.
4:32 what's the small round electronic at the top right corner?
That’s the EGR valve
Thank you so much For this video! You are a great mechanic!
I'm getting a P219a code on my Prius V with 120k miles. Should I try this before cleaning the whole EGR and cooler?
Better wear eye protection when spraying brake cleaner. Get some in your eyes and you will holler out loud. Gloves to for spraying in your hand. OR, a better way to clean that pipe is soak it in Diesel. WAY less fumes and costs much less than canned death. Keep a gallon of Diesel in the garage to clean dirty filthy parts just like yours in the video.
Any idea what would cause it to fill up often? My girlfriends car packs this egr pipe full once a year
its just due to fuel and air mixture that gets burned in the engine that pass through this pipe that causes the build up.
How do I know if this needs to be cleaned? My Prius runs fine, but gas mileage is not where it should be.
What is the point just cleaning out the egr pipe

You forgot to clip in the tubing around your filter into the 3 clips FYI lol but still a very helpful Video thank you.
I was personally slightly triggered by this.
Would you recommend changing the pvc valve at this egg cleaning also?
You can do it when you do the intake manifold cleaning since it’s right there when you remove the intake manifold.

I loved your videos and have certainly bought off your Amazon referral links. I am wondering if you would have insight on this… I recently did the EGR clean out, the pipe, the ugh radiator cooler looking thing, and the EGR valve too. Everything reassembled and car runs like new. So much more power. And check engine light never came back on.
But now I am smelling exhaust when I am driving close to a truck or whatever. Doesn’t matter if my car is on recirculating air or fresh air, it comes in. But if I am not driving next to a smelly truck, I don’t get smell. So smell is not coming from the Prius.
Any idea what step I could have missed in the reassembly that could have caused the recirculating air to still be pulling in outside air?
Have you checked your cabin air filter? I noticed my vent closing for the outside doesn’t fully closed outside air but does have some air come in, I guess that’s normal to have a little bit of outside air coming in even if the recirculating vent are closed from outside air.
@@NutzAboutBolts I was gonna check that it may be due to change anyways. But just strange that I didn’t touch the cabin air filter with the EGR process. I don’t even know what to search for. But could the flap be stuck on outside air coming in? It definitely wasn’t letting that much outside exhaust in before.
@@entao6425 over time the cabin filter can get dirty from debris outside, check the outside air vent on the passenger side to see if it’s covered in dirt, dust or leaves and check the cabin filter. I myself haven’t experience any exhaust fumes or smell after this service… try having the engine hood open and vehicle on to see if you can mimic the smell in the engine bay.

Hey, I just had someone replace my spark plugs on a 2010 (side hustle mechanic) I was experiencing a 5mph MPG drop since Aug and the car has 160K and to my knowledge plugs were never changed. In any case he replaced them, the ones he took out were def in there for awhile but were not too bad looking. In any case he also check maf sensor and lightly used the tip of a flat head screw driver to scape a thin layer of carbon off. I have drive now for 2 weeks and no difference in mpg. I wanted to get the egr pipes cleaned. so can that be done without removing the windshied shroud and wiper motor assembly. I would like to get to bottom of it and your vid tells me you know a thing ot two
You don’t need to remove the wiper cowl assembly
@@NutzAboutBolts Thanks for quick reply. Is just cleaning that pipe enough to perform egr maintenance and can that be a culprit for lower MPG. My car threw a P0304 code about 3 weeks ago I had it reset after the sparks were replaced and the mechanic switched coil 2 and 4 so far the code has not resurfaced but the mpgs are still down about 5 from 45 average. I know it has 160K but hoping to get at least 250-300k out of it
@@staxoffunk1863 it can, but over time, mpg will go down due to wear and tear from the engine.
After cleaning I experienced misfiring. Disconnected and reconnected coil one now it was running well for a week and now I have four codes after a week. I do get a rattle at times I wish I knew of this process before 150k. Codes are p0351 p0401 p3190 p0a0f c1241. I don’t really want to pay the dealer to fix but I think my next best step is to check coil one.
Did you solve the problem, I have p3190 after doing this?
so i just did everything you did, luckily my egr pipe and the intake inlet werent completely clogged. i went ahead and took it a step further and removed the intake manifold to clean it out. 3 of the little ports inside were completely clogged up. i cleaned them out and put everything back together. when i went to start the car, it started fine, then the engine kicked on for about 5 seconds. it started to increase rpm and then shut off. check engine light and hybrid light came on. i'm waiting to get a scanner to check the code. any clue in the meantime what it could be? i made sure everything was connected and tight. possible gasket seal leak?
did all the connectors got plugged back in place? never heard of it throwing codes when you removed the intake to clean it. I've read on the PriusChat forum that people remove the intake manifold and EGR and pipes to clean the oil deposits and never had any issues. I would get it scan and see what the code reads before proceeding forward.
Ok I figured it out. Turns out I forgot to connect the hose to the intake manifold. Once I connected that it was all good. Thanks for all your videos
Nice work.
What tools do you need to remove the intake manifold to get to the holes my car was very dirty when I got the egr out and cleaned it
If the egr pipe is completely clogged, does one need to replace egr, intake manifold and that pipe?
Is this job even worth doing if you dont clean the EGR cooler, valve, and intake manifold as well? I presume if the pipe is clogged the other elements are clogged?
You can add this when doing all the other ones.
Hi NutzAboutBolts, please excuse me for a rather back-to-basics question here: what would the effect be of not cleaning this EGR pipe and its associated ports? What aspect of engine performance would this affect, and by how much, in general, would you say, in your experience?
+kallisjazz it can cause the idle to be rough due to the carbon build up in the passages, and can cause a check engine light.
Will lead to head gasket failure
Thanks this video is so helpful and useful
What's average time to disassemble, clean pipe and reinstall?
30-40 mins.
You were half way there cleaning the EGR system. Very important to clean out the entire cooler too.
Yep, we have a separate video for that 😅
2010 Prius egr information CRITICAL!
If you have e code for restricted egr flow, here's what to do. Seriously, I've done this in parking lots in under two minutes!
Pop off the plastic engine cover, and see the egr valve on the right side. Unclip the wire harness, remove the two Phillips screws, and pull off the cover. Rotate the cylinder counter-clockwise and pull it off. Now, find a lock-washer that fits over the shaft, and clears the spring. Slide it onto the shaft and reassemble.
Here's why, if you want to know.
There's a plastic hub that gets worn down inside of the cylinder and, over time, won't engage the plunger enough to recirculate the exhaust gases. The lock-washer acts as a shim and gets it working again. Allow 5 or so engine cycles (cool to warm, and back again) for the light to reset. Now, punch it! It runs WAY better! Now, use ashtrays, don't beep your car to lock it, and smile more!
my dear friend all the knocking problem and noice problem I could remove it. Simple solution is that don't even open the whole EGR kit. just open the two screws of EGR socket and check is your EGR moving up and down. if it is not then all the problem in GEN 3 Prius is due to this EGR. I can send you detailed solution trust me I was banging my head to all the dealers and eventually I could diagnose and rectify the problem. now my Prius is running like a queen.
Hey Mind Right Life Right, can you help a bro out? The cold season is starting and my GEN 3 did the "knock" yesterday, haha I wanna try out this, can you send me the detailed solution?
Bro just open the two screws which will bring the electrical circuit out and check that is the valve going up and down. If it is then your dash board shall have 401 fault code. If not then the Egr valve needs to get cleaned and it needs to move freely up and down. Let me know if you were able to..
he really nicely explain

A couple videos were saying that means it's 100% a bad head gasket. But is that true? Or should I try the ERG, and also replacing the plugs / coils (they need to be replaced anyway).
I do find it funny that ALL the cylinders are showing a misfire all at once...
Doesn’t hurt to clean this, but could be head gasket issue with the codes
I'm getting those same three codes. P0300 = random cylinders misfire, P0301 = cyl 1 misfire, P0302 = cyl 2 misfire. Replaced cyl 1& 2 coils & Denso plugs, Twice. First with anti-seize and dielectric boot grease, second without. Tried torquing @ 13 ft per pound, and just snugging plugs.
Wondering now if it's injectors, EGR pipe clogged, fuel pump, fuel filter, or head gasket? Dealer wanted to do HG for 3800.00. I can't afford that at all. 2012 Prius V wagon with 240,000 miles. Getting caking on outside of coolant reservoir as well. Replaced a reservoir at 150k when got a red temp light and auto parts guy found it. Ordered reservoir from RockAuto. Wasn't misfiring then though. Just temp light.
Codes: P0300, P0301, & P0302. I have a handheld obd reader. I've been popping misfiring cylinder codes every 30k, for the last two years. Got P0300 for first time ever, along with other cyl codes, this last time. Something else keeps causing the cylinders to repetitively misfire. What is it?
Nobody seems to be able to pinpoint the exact cause.
hey bro were are u located?
Awesome tutorial. Thanks!
Hi Can you make a video showing how to recharge the Prius 2010 air conditioner?
I recently recharged my AC at the dealership. You need a machine to do that service.
You can recharge with pure refrigerant without any additive, no oil. Just pure can, smallest can, and completely new charger hose. I would buy new 3 lines hose with pressure meter on it that can be connected to high and low pressure lines. So, you are not overcharge it. 3 line hoses also good to diagnose what the real problems, compressor, condenser, evaporator, or just low refrigreant. Just recharge it and do not use any oil unless it is ND11 (non-conductive oil). PAG oil for other cars will short your 110V AC compressor and destroy it.
I change all my spark plug on my Prius 2010 but still engines still shakes when the car start up can you help me with that please
Any check engine light? Have you cleaned your EGR pipe and cooler?
No I haven’t
Check engine light stay on
@@genelfl check what’s the code. Then go from there. The 2010 common issues are headgasket. But check the code to see what it is.
The code I get is P00302
I did this and it didn’t resolve the issue. Unfortunately I think the intake manifold has to be cleaned completely in my situation :/
Isnt it better also remove the egr valve?
would be good to suck the stuff out with a low power vacuum.
