Yep, I wanted to try some different things since I had heard a lot of different things that people had tried. The oven cleaner for me was handed down the best on the EGR Cooler. The intake manifold cleaned ups beautifully with simple green, hot water, and rinsing off. Using a small wire brush for the small passageways was simple with a quick blast of brake cleaner followed by the degreaser soak.
Going to undertake this on 2015 Prius v, one of the last 3rd gens drives and feels internally identical to the 2016 eco Prius. Need to do some future proofing as I just hit 100k this quarter and I am putting around 12k miles per quarter as of now.
Yep, at 100k you are past due. I recommend every 75-80k miles as do others that I've seen. Take your time as the first time is the trickiest, but once you do it and understand everything it's a breeze. Leave the nut/stud from hell off after removing the EGR Cooler as it's not needed and makes things very simple the next time.
@@jimsgaragetoys I’m grateful to connect to your helpful channel. What is your advice on proactive replacing water pump regarding head gasket lifespan? Worth it ? Or just a bad recommend from shop?
@@humbob2845 Thanks! I just replaced my water pump and thermostat at 150k miles and that seems to be when many see them get tired. I would be ready to have to change it around that point or anytime after that. I was seeing a couple of times that the coolant temp spiked and I wasn't sure if it was the water pump or thermostat but I do recommend replacing both at the same time. I did show a video in changing that too.
I believe that the EGR valve itself stays clean because the exhaust hasn't been cooled yet. In the cooler, and downstream through the manifold, gummy condensates will have formed during the cooling process. My Isuzu truck's EGR hasn't been cleaned in 36 years, still flows properly and opens/closes properly, as it has no EGR cooler.
Im going to attempt this soon and am watching as many videos as I can to absorb the info from many perspectives, thanks for all the tips. Alos is that and MR2 on the lift behind you?
I've been working on this for a few days now. I spent a day and a half just removing one nut on the cooler. I soaked the egr cooler in Purple Power over night and I'm assuming that it should be a straight passage through for airflow so if I pour purple power through one end and it doesn't come out the other end, it must still be clogged, right??? I'm gonna try some of that pbw that you used and see if it works better
Yes, if it doesn't run trough it then it's still plugged. The best thing I've found to clean the EGR cooler out is over cleaner. I strictly use that now after experimenting with many different things. It also works quickly. Congrats on getting that nut from hell off! That's the worst part. Now remove the stud and cut off the arm that was used for that nut as you don't need it. It makes it so much easier to get it on and off in the future.
Yes, any kind of degreaser should work. I found it heavy enough though that it needed to soak. You will also need to use a small wire brush to clean out the small EGR holes using a degreaser too. This is why I have a spare intake manifold, I can remove the dirty one and put a clean one right back on and take my time cleaning it.
Funny seeing this question on a video for my Prius. 🤣 I have thought about one but that will be down the road as it's not high on my list. And it's expensive for what it is.
I had pickup a used set at local mechanic including intake manifold, pipe, egr,egr cooler for 120$. For the cleaner I use the 1 gallon carburetor cleaner to soaked everything and blast it with pressure washer no scrub.
The screw of my egr motor is striped the head also! I cut a slot and put the 2 nuts back on the studs. Hold on the vise hammered when back out it comes right out.😊
Nope, never did. They were Philips head screws and they stripped out. I wanted to see what the inside looked like but I was able to see it in another video, at least what the electronics and spring assembly were. I just cleaned out the other areas since I could get to them with the brake cleaner.
Good job, Jim! I cleaned all this with ovencleaner, also works superb

Thank you, in the process of replacing head gasket now!!!
This will help prevent that from happening again!
Thank you so brother. I am in the process right now.
Good job! Love to hear it!

I just spray out the area that is accessible if I see anything that looks dirty.
Thanks man!!! Very helpful content here
So happy I could help!

I've done several videos so each of them will have a little different twist to the process. And yes, that's my 89 Supercharged MR2. 😍

Can I use engine degreaser to spray and clean inside the manifold? do you think it works?
Yes, any kind of degreaser should work. I found it heavy enough though that it needed to soak. You will also need to use a small wire brush to clean out the small EGR holes using a degreaser too.

Any thoughts on an aftermarket intake for your gr?

I pickup a used set from egr cooler to intake manifold for 120$ egr was bad! So 50/50. I swap the egr motor out that was easy! 😂

Nice 1986 MR2..😮
It's actually an 89 Supercharged MR2. 😍😉
Did you end up getting the screws off the valve?
Nope, never did. They were Philips head screws and they stripped out. I wanted to see what the inside looked like but I was able to see it in another video, at least what the electronics and spring assembly were. I just cleaned out the other areas since I could get to them with the brake cleaner.
