Hal - YES !! I watch a LOT of YT videos (I'm disabled) and mostly about DIY. Often people know their stuff but not VIDEOGRAPHY ... sound, lighting, camera work, scripting, etc 1st time here and this one had it all PLUS a funny, super dry humor. Deserves LOTS more fans !
A relative gifted me their 3rd-gen Prius as it had a blown head gasket. I started disassembling the engine to remove the head a few weeks ago and got to the EGR studs and almost broke the long one (the external torx part started to twist). My daily driver sprung a head gasket leak and is a bit more of a project, so I came back to the Prius to see how I could do with continuing the job. That stud came right out. My neighbor finds humor in my shenanigans and came over to give me company and brought a couple tools I was missing. That “disposable member” nut was a challenge. I am thinking the vandal may be onto something with cutting it off and filing the remaining bracket smooth. I joined Priuschat and will look for the heated argument. LOL. I subscribed and appreciate your great documentation of these jobs. Also, thanks Margie for the camera work and PDF drafts!
I performed this job today on my 2015 toyota auris hybrid which has the same set up as the Toyota Prius. I soaked my egr cooler overnight in degreaser followed by a thorough jet wash the following morning and then Hooray I could see daylight through my egr cooler. I took Merv’s advice and cut the dreaded bottom bracket as it is easier to take off next time and it is easier to put back on. Take your time when performing this job and make sure you clean everything properly especially the small holes in the manifold. Carb cleaner / egr cleaner is not sufficient enough to clean this and I advise something stronger. Some say don’t use oven cleaner but I used mr muscle and it stripped the carbon away. Some parts of carbon I stripped with a metal wire hanger. Please be thorough when doing this and take your time and do not forget to change your pcv valve when performing this task. Now my car drives with a lot more power 😊
Man, I thought I found the best videos out there. And then I came across yours, so good and the humor had me sitting here drinking coffee alone laughing out loud literally lol. Thanks so much for the awesome videos and the expendable bracket man that made me over filled with joy. Can’t wait to cut that sucker off and toss it. Thanks again awesome videos, and great humor.🙏❤️
Just became a 3rd Gen Prius owner and your EGR pipe and Intake manifold video was so helpful. Thanks a lot. Now I’ll be doing the EGR cooler thanks to this video
Tip for using magnets. Get some small rare earth ones that can fit in your glove finger tips. Then when you spin off those tough ones you can’t see, the magnets in your finger tips will keep them from dropping.
The whole package. What a bunch of applied skills. Amazing craft and awareness of how audience learns and what they need to learn. There are different levels of knowledge here. Because of your skill and work you will keep the old folks entertained, too. I am new to your presentation - I'll look around just to see what else you descided to explore cause it was so fun watching.
Our 3rd gen Prius with 252824 miles has a P0401 code for EGR insufficient flow. This video and your knowledge is a great help. I would say the third AI image looks most like some sort of engine compartment but nothing like a 3rd gen Prius!
fyi to remove the coolant hoses i use a 90* pick with a doll point with a bit of grease work around the hose and walla aldo the best video i have seen on the tube!!!!!
Totally love these videos. They provide entertainment, while at the same time expertly guiding me through the processes. Reminds me of the old John Muir book "How To Keep Your Volkswagen Alive. A Step By Step Manual For The Complete Idiot" - Technical expertise mixed with great humor. Awesome! Thanks!
BTW: Thank you Thank you SO MUCH about additional editing of the video. Specifically, coloring the hot and cold fumes, and the area you are talking about! makes so easy to follow your thinking line.
9:46. Instead of torque stud, I used 6-mm socket. Feels a bit loose, but it worked, Did not strip it. Again, you can trow away the cursed torque stud, and replace it with long M8 bolt and a nut that is screwed all the way to the head of the bolt before installation. :-))) Again, I love your coloring!
Thanks for your time and video it really helps me since I'm working on my 2011 Toyota Prius it's a pain in the butt what was your video as a blessing again thank you and blessings
Thanks so much, the soaking over night and the power washer made it super clean. Some one broke into my garage also and the bracket was gone. Weird. :) Thanks again for the great video....
A word to the wise...after fighting with the "expendable crew member" for a day and a half, I came up with a brainstorm that maybe my tool was too big (no pun intended) because of this hose that's right next to it that prevented me from getting a 12mm deep well and 3/8 drive ratchet in there. So I ran to Napa and got me a 12mm 1/4" drive deep well socket along with a 3" and 6" extension just in case and with the help of my long handled 1/4" drive ratchet, I had it out in a matter of minutes
Hey, Great job Marv! To really get the EGR cooler clean besides Easy Off, I used a high pressure power washer with the cooler screwed to a big block of wood and I got it brand new clean!
Why you don't have a million subscribers is certainly beyond me. Your videos are great and you very clearly put a great deal of work into them. Thanks for creating and sharing! Appreciate your hard work.
After doing this job once already, got a really good laugh on your tutorial. Great visuals, looking forward to doing this job again replacing EGR and cooler at almost 200,000. Thanks for the tutorial, laughs, and don't forget about us female mechanics. 😊
Wow, this was a very informative, entertaining video. The voice of Dukes of Hazard, tv show, just dated myself. Thank you so much, the tip of sawing off that little pestie bracket was the highlight for me. I've been waiting for months to tackle this project and now with your video and others I've watched, i think I'm ready. Thanks uncle Jesse, was that his voice?
A more secure way to capture the nut you had the magnet on is to get a small piece oh insulation tape and put it on the inside of your socket then push it onto the nut/bolt you are undoing or fitting and it is a nice snug fit. Regards Chris
This video is so well done and funny and you explain everything so a 10 year old can do the job I got to your channel by someone else saying to go to prius shaking I couldn’t help it but subscribe right away And give you a thumbs up for the good work you do for your community. My Prius has a blown up head gasket because it was losing a little bit of coolant. I had put bars leak a few times and it seems like it was getting better just losing a little bit of coolant. And then a few months down the road it was shaking a lot at starting and even putting in drive. It would shake for about 234 minutes. So I decide to ask my mechanic to put the blue devil head gasket sealant which he did and now I don’t have anymore heat coming in the car and when it starts shaking engine light came on I checked the code and have cylinder one and four misfiring. Can someone help me to diagnose this? Thanks
13:20 I used a long bench to get higher. then when leaning, not only my lower back, but also my knees. they tried to bent beyound the final stop-point...
i took apart the "forbidden" egr motor as well. nothing so darn forbidde, just dont loose anything. There are a couple of springs, but they are under the rotor. Also, when removing the phillips screws, do yourself a favor. send these screws to make company to the stud from heII. replace them with hex-head bolts or allen wrench bolts, 5 mm. Such bolts are used often on bicycles.
I cleaned my egr heat exchanger with boiling water and leaf blower. It helped, but it took 5 hot water baths. I would suggest a laboratory bunsen gas burner. The flame is very hot and pointed inside. This is all stainless steel and you can heat it safely to red-hot, i.e. 600 C deg. All garbage burns before this point.
my 2011 prius has 81k and I am thinking about replacing the radiator and inverter coolant, might be a good idea to do both egr and intake manifold cleaning at the same time.
Well, mine was really getting up there in mileage, plus after seeing how dirty the air intake manifold was, I figured it was time for a thorough cleaning.
14:22 I removed all high voltage cables, and the entire low-voltage harness. and the console under the el motor coolant, an swung the cooling container away to make space. nope space is never enough.
7:23: "giant pain in the aaaaa...." i cut it tru, so that as soon as you loosen the nut, it can slide off. nope. did not help. still the two studs on the very far entrance are obstacle. well, the heII with the 7:23 bolt. If you very much insist, there are special bolts with long thick necks, that have about 10 mm of thread on the front. They can be used instead, and the head is outside, easyly accessile with a wrench. Or, take a long enough M8 bolt. put two nuts at the end, leaving as long as you want thread , tighten them against each other. Again, the head is now on the open, accessible to most wrenches.
what do you think about just removing the EGR valve and cleaning that, disconnecting the Exhaust pipe from the back of the EGR cooler, keeping the coolant lines attached, and just blowing it out real good with compressed air? The Car Care Nut suggests this method, wondering what you think about it. How necessary is it to make it spotless like that? I don't really have a problem on my end, just doing it as preventative measure while changing spark plugs
Well, I'm tempted to say it's the lazy way out, but sometimes lazy is better. HOWEVER, seems to me it depends on how clogged up the thru-channels are. It's hard to tell by shining a flashlight through because it's not really a straight shot, and if she's still attached to the exhaust manifold I think it would be hard to see in there.
if it's really clogged you can't just blow the debrie out. I took my EGR-cooler off and had to use ovencleaner (natriumhydroxide) to solve the problem. Took me a while but it's like new now. I mean, the job is difficult for an amateur like me and I just thougth: If I do it, I do it properly and now the cooler is cleaner than new. Also intakemanifold is cleaned a the car runs a lot better and smoother. Just invested time and no money! Take good care of your car and it can last a very long time, so that saves a lot of money. By the way: sawing off that difficult mounting point underneeth is something that I'll do next time
Wow! That's a pretty advanced approach! I honestly have to admit that I don't know much about it, other than it uses sound waves. Please share how it exactly works and what your concerns are. I can't imagine how sound waves would be harmful, but there must be some reason you are worried. Tell me more.
@@MervsServiceSecrets I spent yesterday's whole morning to remove the rear nuts (after removing the wiper panel) and the lower "pain in the a**" nut, that one gave me trouble... :):)
@@MervsServiceSecrets Too late for me, I just bought a cooler from toyota, Mine has 300k on it and it was CLOGGED bad. also, the pipe coming from the exhaust has build up in it. I guess you guys with lower mile cars dont have to worry about that.
❤❤❤❤ so ya, misfires on my Prius got me delving TH-cam’s depths for why replacing the spark plugs didn’t make everything hunkypurry again. Hours of video watching later, and slightly less time spent on cleaning the maf and replacing the pcv (all new acronyms to me), still wondering what the egr is on the list of things that might be wrong that my code reader is advising me, come across this video. The best of TH-cam mechanics. Thank you! Sure hope it’s not my egr and swapping these two coils out is gonna do the trick instead
It could be a secondary issue, but after replacing our egr valve we now have a strong exhaust/unburnt fuel smell at idle in our prius (obviously except when in ev) if vents are set on outside air. Inside air we cannot smell it. What did we fudge up? 😢
@MervsServiceSecrets Yeah unfortunately. It could be an exhaust leak somewhere (we'll get it checked out when we have the money) but we were trying to figure out if there's anything we could have accidentally done in that system or not connected properly that would bring us this issue. No CEL and no codes
I'm a DIY hobbyist just like you, and of course we all attempt these repairs at our own peril, but a couple things leap to mind and I'll throw them out there just in case they resonate: Maybe you forgot to reattach the PCV hose? Coolant leaking from when you clamped the hoses? (Maybe one got damaged or wasn't reattached right) Gaskets properly reinstalled in the various parts of the cooler, including the one that goes between the cooler and the exhaust manifold? Hopefully these suggestions might spur some insight. Also, if it helps, this video shows my observations about those gaskets: th-cam.com/video/QGcZYGA2cnM/w-d-xo.htmlsi=X_aMkFf05ceWLW7n -Merv Himself
This is a great video. This car takes some work and it will eat your nerves. Part of the design of this car are not so smart especially the Winshield which is very easy to break and that cooler bracket on the bottom is just bad painful design not even necessary. I learned and done the head gasket alone and it was great for 23k miles now is running super rough misfiring cylinder 1,2. I’ve taken all off the manifold the cooler soaking overnight and the valve I gave a good cleaning,will see if this will solve my problem. The manifold was very dirty but after cleaning it only not a difference at all. After I took the egr valve off it was full of carbon on both ends. The design of the egr system is terrible as you have to keep doing it over and over.
Do you think you can do alot of people a favor by showing the egr cooler cleaning of generation 4 prius? It involves methodically removing the inverter first to get to the cooler. A bit more challenge for you. Many thanks in advance...
Well, if you buy me the gen 4, I'll tear it apart. 😄 In the meantime, here is how I cleaned the Gen 3 cooler: th-cam.com/video/QGcZYGA2cnM/w-d-xo.htmlsi=D6Q6q10QLFQb1C74
Maybe needle nosed vice grips? Or a very small closed-end box wrench. Just enough to grab the end of that stud and start her turning. And don't forget which way she needs to spin. It's easy to get disoriented.
@@MervsServiceSecrets Finally got it off! Man I used 3 bottles of parts cleaner on that cooler and some long brushes and still can't see through that thing! you recommend soaking in purple power overnight? what else can I do to get it clean
Hey Merv, I did the EGR service, intake manifold on 2011 Prius with 194k miles. The car was running fine but I figured I do the service to avoid any problems. I put everything back together and I started the car, it ran for about 10 seconds and started to surge and stalled. I started it again with the same results. Got p3190 and p3191 + p0a0f codes. Any idea what the heck I did wrong? Or why it's doing this?
I did exactly what everyone was going to tell me. I went back and checked my work. This Dumb@$$ forgot to connect the PCV hose to the intake manifold. Thank you for your awesome videos, with plenty of Organic humor.
I don't have a magic answer for you, but it might be the EGR valve itself is having problems opening and closing. Watch this video to see how I dissect it --> th-cam.com/video/QGcZYGA2cnM/w-d-xo.htmlsi=DK9d2PCoaOBI0O5h Might also be something as simple as a sensor gone bad. Maybe check out priuschat to see what other's who've had the same problem might recommend. You might also be able to determine the best order to fix/replace things in. (starting with the lowest cost solution, then working your way up). Hope this helps. -Merv Himself
The hell bolt isint that bad if you put the silver cover back on the engine and lay on it feel for the nut with your left and and come straight in with a extension with your right I've removed these coolers like ten times from every which angle even standing in the engine bay with the hood off (have a nice crack on the relay box from resting my knee :/ )and this seems to be pretty effortless way of doing it be sure to wear a hard hat so you dont bump your head into the windshield trying to see what your doing im about 3 concussions away from getting a free cooler from toyota
*Be sure to post your opinions about the Artificial Intelligence designs in the final segment.*
I really cant believe how much effort you put into these videos man 😯
Glad you like them!

Excellent video with plain-speak and clear images. I may just pay $1,000,000 to have a mechanic do it, but, maybe not...

Wow, thank you! Please spread the word! Share our links on social or anywhere you can. It really helps the algo.
Its more entertaining than "Down to business" for DIY'rs. More effort is put to the narration than showing.
Just became a 3rd Gen Prius owner and your EGR pipe and Intake manifold video was so helpful. Thanks a lot. Now I’ll be doing the EGR cooler thanks to this video
Be sure you do plenty of research beyond my personal escapades. And be careful. It's not as fun as it looks.
Tip for using magnets. Get some small rare earth ones that can fit in your glove finger tips. Then when you spin off those tough ones you can’t see, the magnets in your finger tips will keep them from dropping.
Great idea!

Cool, thanks
That vandal at 17:05 is the best thing that could ever happen to you, send him my address!! He might help, I mean vandalize my EGR. Great video!!
i was laughing too hard cuz i believed it for about 5 seconds
Best video highlighting the car parts makes it easy to follow. Good stuff
Thanks, glad it was helpful!
fyi to remove the coolant hoses i use a 90* pick with a doll point with a bit of grease work around the hose and walla aldo the best video i have seen on the tube!!!!!

Hey,
Great job Marv!
To really get the EGR cooler clean besides Easy Off, I used a high pressure power washer with the cooler screwed to a big block of wood and I got it brand new clean!
I used the pressure washer trick, but I got sick of chasing the cooler down the driveway! Screwing to a block of wood is an excellent tip!!!
top man , you made me laff .did the police ever find ho cut the bracket of the cooler ,keep up the good vid`s all the best from the uk
He was one crafty feller.
Why you don't have a million subscribers is certainly beyond me. Your videos are great and you very clearly put a great deal of work into them.
Thanks for creating and sharing! Appreciate your hard work.
Wow, thank you! Sharing my videos helps a lot. Please do!
Nice EGR bracket mod! I guess that was the first break in ever that actually worked out. AI and it's parlor tricks.
After doing this job once already, got a really good laugh on your tutorial. Great visuals, looking forward to doing this job again replacing EGR and cooler at almost 200,000. Thanks for the tutorial, laughs, and don't forget about us female mechanics. 😊

Did you try fuel injector cleaner? When Demille owned the car, he actually paid a dealer to clean the injectors and that solved all misfires
13:20 I used a long bench to get higher. then when leaning, not only my lower back, but also my knees. they tried to bent beyound the final stop-point...

i love it
Best car videos anywhere! along with real life aches and pains.
Great videos thank you for making these
Glad you like them!
Should i do this before im running codes as prevenantive maintenance? Or should i wait until i have a problem
Well, mine was really getting up there in mileage, plus after seeing how dirty the air intake manifold was, I figured it was time for a thorough cleaning.
Amazing

How did you manage to remove lower rear bolt at 11.20? I can't remove oil cooler because of that bolt (and nut)... 😢
I came around the other side of the engine and got in there with a small wrench.
@@MervsServiceSecrets I spent yesterday's whole morning to remove the rear nuts (after removing the wiper panel) and the lower "pain in the a**" nut, that one gave me trouble... :):)
by the way, I spent like half hour to understand that was not a 10mm nut like the other ones!
Waitin' like a rooster in the hen house for the EGR cleaning vid
😂 Perfectly phrased! We are working on that video right now and hopefully it will be finished faster than a knife fight in a phone booth.
@@MervsServiceSecrets Too late for me, I just bought a cooler from toyota, Mine has 300k on it and it was CLOGGED bad. also, the pipe coming from the exhaust has build up in it. I guess you guys with lower mile cars dont have to worry about that.
"Lower mileage cars" 😂😄😆. Brother, good for you! 300k? Damn fine!
@@MervsServiceSecrets wouldnt have done it without your video. Happy to report the car is SMOOTH again. shooting for 500,000 miles now!
thanks for making this video!
My pleasure!
❤❤❤❤ so ya, misfires on my Prius got me delving TH-cam’s depths for why replacing the spark plugs didn’t make everything hunkypurry again. Hours of video watching later, and slightly less time spent on cleaning the maf and replacing the pcv (all new acronyms to me), still wondering what the egr is on the list of things that might be wrong that my code reader is advising me, come across this video. The best of TH-cam mechanics. Thank you! Sure hope it’s not my egr and swapping these two coils out is gonna do the trick instead
Toyota issued a bulletin a while ago stating that they acknowledge this is a routine service item on 10-14 model Prius
It could be a secondary issue, but after replacing our egr valve we now have a strong exhaust/unburnt fuel smell at idle in our prius (obviously except when in ev) if vents are set on outside air. Inside air we cannot smell it.
What did we fudge up? 😢
It's been a few days since your post. Is it still persisting?
@MervsServiceSecrets Yeah unfortunately. It could be an exhaust leak somewhere (we'll get it checked out when we have the money) but we were trying to figure out if there's anything we could have accidentally done in that system or not connected properly that would bring us this issue. No CEL and no codes
I'm a DIY hobbyist just like you, and of course we all attempt these repairs at our own peril, but a couple things leap to mind and I'll throw them out there just in case they resonate: Maybe you forgot to reattach the PCV hose? Coolant leaking from when you clamped the hoses? (Maybe one got damaged or wasn't reattached right) Gaskets properly reinstalled in the various parts of the cooler, including the one that goes between the cooler and the exhaust manifold? Hopefully these suggestions might spur some insight. Also, if it helps, this video shows my observations about those gaskets: th-cam.com/video/QGcZYGA2cnM/w-d-xo.htmlsi=X_aMkFf05ceWLW7n

Might as well replace spark plugs
Ive seen another video where a guy replaced back thread piece and Nuts with a Hex Bolt, easier to take off
Interesting idea!
😮 man !!!!!!!!!!!!!!!!!!!!!!!!
One should never block off the egr and replace sensor with a resistor.
You are so right. Like you, I also could never recommend such a thing.
This is a great video. This car takes some work and it will eat your nerves. Part of the design of this car are not so smart especially the Winshield which is very easy to break and that cooler bracket on the bottom is just bad painful design not even necessary. I learned and done the head gasket alone and it was great for 23k miles now is running super rough misfiring cylinder 1,2. I’ve taken all off the manifold the cooler soaking overnight and the valve I gave a good cleaning,will see if this will solve my problem. The manifold was very dirty but after cleaning it only not a difference at all. After I took the egr valve off it was full of carbon on both ends. The design of the egr system is terrible as you have to keep doing it over and over.
Do you think you can do alot of people a favor by showing the egr cooler cleaning of generation 4 prius? It involves methodically removing the inverter first to get to the cooler.
A bit more challenge for you.
Many thanks in advance...
Well, if you buy me the gen 4, I'll tear it apart. 😄 In the meantime, here is how I cleaned the Gen 3 cooler: th-cam.com/video/QGcZYGA2cnM/w-d-xo.htmlsi=D6Q6q10QLFQb1C74
Man I’m having the hardest time getting that damn stud off the bottom! Like I’ve been trying for days can’t get my egr cooler off 😭
Maybe needle nosed vice grips? Or a very small closed-end box wrench. Just enough to grab the end of that stud and start her turning. And don't forget which way she needs to spin. It's easy to get disoriented.
@@MervsServiceSecrets Finally got it off! Man I used 3 bottles of parts cleaner on that cooler and some long brushes and still can't see through that thing! you recommend soaking in purple power overnight? what else can I do to get it clean
Hey Merv, I did the EGR service, intake manifold on 2011 Prius with 194k miles. The car was running fine but I figured I do the service to avoid any problems. I put everything back together and I started the car, it ran for about 10 seconds and started to surge and stalled. I started it again with the same results.
Got p3190 and p3191 + p0a0f codes.
Any idea what the heck I did wrong? Or why it's doing this?
I did exactly what everyone was going to tell me.
I went back and checked my work. This Dumb@$$ forgot to connect the PCV hose to the intake manifold.
Thank you for your awesome videos, with plenty of Organic humor.
My 2010 died on the freeway. P3191 code. Is it possible that the EGR cooler is blocked and keeping it from running? It is not the fuel pump.
I don't have a magic answer for you, but it might be the EGR valve itself is having problems opening and closing. Watch this video to see how I dissect it --> th-cam.com/video/QGcZYGA2cnM/w-d-xo.htmlsi=DK9d2PCoaOBI0O5h Might also be something as simple as a sensor gone bad. Maybe check out priuschat to see what other's who've had the same problem might recommend. You might also be able to determine the best order to fix/replace things in. (starting with the lowest cost solution, then working your way up). Hope this helps. -Merv Himself
This video is really scary. I thought for a moment it was a Stephen King's novel, but anyways, it describes how to do this job really well.
Use a power washer to clean the EGR, you save $hundreds, is quick, clean, and cheap...
The hell bolt isint that bad if you put the silver cover back on the engine and lay on it feel for the nut with your left and and come straight in with a extension with your right I've removed these coolers like ten times from every which angle even standing in the engine bay with the hood off (have a nice crack on the relay box from resting my knee :/ )and this seems to be pretty effortless way of doing it be sure to wear a hard hat so you dont bump your head into the windshield trying to see what your doing im about 3 concussions away from getting a free cooler from toyota
That's exactly the way I did it. But without the engine cover. Plus, I added one very important accessory.
@@MervsServiceSecrets and @jacobgreen3963 , the accessory was simple yet brilliant.
@@MervsServiceSecrets The accessory is next level.
What a pain in a _ _ just to get to this point 5:15 🙄
Good thing I just cleaned my EGR before seeing this video. Otherwise, the expendable is gone too
Right on
😂 hilarious 🤣
17:00 best modification ever made to a car. Whoever design this crap bracket is purely evil.
So true
😊
you did the easy part, now clean out the cooler
After watching this, i decided to trade in my car for a newer one. Simpliar... Lol!!!
Simpler, sure. But more fun??? (Oh, crap. You're right!)
Come home to SIMPLE RICKS....
That Simple Rick was one helluva guy. And his wafter cookies were a special kind of down-home tasty you just can't find anymore.
17:00 Angle Grinder!!!! Angry Angle Grinder. And send this POS to toyota head quarters with reverse postage.
I love that idea!
Too much trouble
i would like to watch this video, but this guy's comedy routine is annoying as hell! oh well.....I'll find another
OK I can’t stand this guy’s voice. I’m watching different video.
Спасибо мужик. Лайк 👍 с ходу
