Torque for transmission oil plugs?

You came to the right place. If you think of more just lemme know.

 

Welcome to Prius Chat .

Good luck with your maintenance. For the egr system, it will be difficult to torque to spec as some of the bolts are hard to access.

Let us know if you have additional questions .

 

I'd agree: just torque the ones you can reach with the torque wrench, try to give the others similar oomph. The have very low torque values; a 3/8" torque wrench is good (more appropriate range), 1/4" even better. You'll for sure need an E8 Torx socket, and an E6 is needed if your remove the throttle body studs. A ratchetting box wrench 12 mm, with swivel head if possible, is very handy for some of the rear connections.

Good thread on EGR cleaning:

EGR & Intake Manifold Clean Results | Page 3 | PriusChat

There's some others too, just google "priuschat egr cleaning" and similar. Worth reading the above from stem-to-stern.

 

I now this is older but in case anybody reads this.... remove egr cooler and soak in gas or carb cleaner for 24 hours a couple of times...then you must push a wire through each tube... utility marker flags work pretty good.
Carb cleaner alone will not do it....you can also try oven cleaner....keep flushing with water until runs clean. It's a real time consumer...but I wanted mine like new... I also cleaned the intake and throttle body..and installed a catch can.

 

You could also use a pressure washer and be done in 10 minutes.

Taking this to a car wash and using their wand if you don’t have a pressure washer works too.

Happy holidays .

 

I think Oxi-Clean is similar to oven cleaner, albeit a little less caustic. Using strong/hot Oxi solution soaks, with about 6 hours of patient soaking, hourly drain/flush/refill, my EGR cooler came out looking like new. Without hesitation I would vote for a slightly caustic cleaner over a volatile/flammable hydrocarbon: much easier to work with, and ok to rinse down the drain.

I have visions of Ernest P. Worell Cleans his EGR Cooler: I'm pretty sure if they put me together with a pressure washer and an EGR cooler I'd launch it, lol.

 

Securement isn’t too bad. I use a lawn chair and it works well.

But if you want to try and take video of yourself, we can always use a good laugh .

Really not that hard to secure, but I use what I got.

 

How soon till your next cleaning? You were saying this would give some idea as to the efficacy of Oil Catch Can on the EGR carbon build-up.

 

Currently at 193 k miles and added te catch can at 173 k miles last year around this time. My plan was to do the next circuit cleanse around 50 k miles or next year around this time.

But that assumes I don’t get the Prime itch sooner.

Still catching a couple of ounces in the catch can and consuming about a quart of oil every 5k miles or so. Better to catch t than pass it along.

But I think every 50 k miles is right for my situation.

 

The plugs are M18x1,5 thread. Unlike regular bolts that hold parts together, they just hold themselves in place, The friction between the aluminum washer and the zinc plated plug and between the aluminum washer and the aluminum casting of the transmission case holds in tightly in place when the plug is tightened down. Toyota specifies 29 ft. lbs. Anything over 20 is fine. I just run them down until contact and do a quarter turn. That's what professional mechanics do. I've never seen them go through the bother of bring out a torque wrench.

 

Yeah just in case it was overflowing, I checked the OCC yesterday, about 2.5 months and 1200 kms (why do we have a car???), and there was maybe 15 cc. Had that coffee-with-cream look, typical for winter.

 

Mine had 206,000 miles...the stuff was like concrete....

 

Ultrasonic cleaner? Maybe with a solvent bath? Nobody here's reported trying this yet tho.

 

I bet a pressure washer would blast right through it.
