Is there an EGR cleaning/replacement procedure that Toyota performs?

nothing from on high. if you can find a dealer that understands, they will clean the whole circuit. but most want to replace the valve and manifold if you can get them to do anything at all.

there is a @NutzAboutBolts youtube if you can find a mech willing to follow along.

 

If there is, I'll bet it is wallet-lightening!

 

In a word, no. You can probably talk them into replacing the parts you list, but they're going to feel weird about it and they'll probably find a way to make you feel weird for asking. That's no way to go when you're paying top dollar.

They execute procedures dictated by the mother ship. And there really isn't one for this, other than wait until the EGR pops the head gasket and then offer you a new engine or a trade-in allowance. Mind you I do not think this is at all deliberate; it really is just something that has slipped through the gaps.

Lots of cars have EGR systems, and Toyota's is far from the first to suffer clogs. Nothing about this repair involves the hybrid parts of the car. Essentially any corner garage should be able to handle this- although I realize you are likely to encounter a few who don't realize that this is just an EGR cleanout job just like on a Ford, Subaru or VW.

 

When I went to the dealer about egr cooler maintenance, I had no codes. I did have almost 200k miles and knew the egr cooler would be clogged. The dealer offered to clean the egr valve and replace the egr cooler for $800.

I had an independent shop claim they could clean the cooler and the cost would be half. Days later the shop gave up trying to clean the cooler passages which were totally clogged and we ended up buying a new one from the dealer. The dealer had to bring it in from another city so the job took a week and the costs were as high as the dealer.

I did take the old stainless cooler and cleaned it with a wire spun by a drill, soaking and more wire action. I sold my old one on ebay and ended up saving a buck not counting my time. And I did not do the primary work.

If I wanted to get it done with lower cost, I would buy a new cooler on ebay for around $150 and have my mechanic do it. It requires removing the windshield wiper assy and the intake manifold, so also replacing the pcv and adding an oil catch can would be a good plan.

The egr cooler is part 25601-37010. The second and third pic are used parts "cleaned" up. Some sellers will push used coolers that are still clogged, so buyer beware on used.

 

Maybe even the disappearing act .

 

An involuntary conversion....

 

I don't remember removing the wiper stuff when I did mine...... though I don't always remember what I did the previous day.
I bought my extra cooler from a junkyard for $40 or $50. I did have to remove it but was pretty easy as they didn't care how I got it out, and the master cylinder stuff was gone.
