Aluminum replacement for plastic rear coolant bypass joint

Well, at least you could then do the timing cover at the same time.

 

Did folks find a solution for the 90 deg elbow? If not, you can buy preformed 90 deg silicone hose elbows. It would require another pair of joints when you splice from the elbow to the hose.

That is correct, I just got mine done, the intake manifold was removed to get acces. The replacement still is plastic.

The Lexus uses an aluminium one.

IMHO, This is one of the many things that Mike Sweers have done to this trucks, decreasing their QDR.

 

@Jowett did you get this installed? Would be interested in any feedback. I may actually get this for the inevitable down the road when my clutch, timing cover goes and do everything at once, may even put on solid motor mounts.

 

It's bolted up and has a 90 elbow inserted. I'm trying to locate the same elbow in Stainless.... I have not yet run it, but can't see any issues. I'm also looking at having a new piece cast with the port in the proper place.

 

If you get a part made, I'm in.

 

You may not want to use a stainless elbow and Stainless and Aluminum together can easily cause galvanic corrosion, unless the stainless were passivated.

 

Good catch.

 

Pics of the install?

I don't need it immediately, but I would buy one regardless if this was available.

 

Good to point out! I am already thinking a nice hard anodized coating for the bypass joint will do the trick. That will produce a true lifetime part.

I'll grab pics asap.

 

I still have a heater core from a jeep liberty BNIB, so suffice to say, if you bring a solid replacement part to market I will buy it.

 

This will push my growing mod queue out to 2024

 

Is it just me, or does it appear that you have to un-do the lines going to the direct injectors (if you go the 'taking the intake apart' method)?

I think I heard, but would have to confirm, that if you undo that line you're supposed to just replace the whole thing.

Hopefully Toyota updated the part as I haven't heard of much issues with 2018 and up, and I have a 2019 .

 

Jesus, I hope youre mistaken. Sounds like another extraneous part on a truck that I should have not gotten involved with.

 

For what it's worth, I just noticed that my wifes car (which hopefully will be replaced at some point soon) has a plastic T-Stat housing.

It's a 2008 with about 120k on it.

Sadly the T-Stat isn't doing so hot (failed open) and it's also time to replace allllll the coolant hoses as they are 13 years old.

Coming full circle, if Toyota hopefully updated that part on the back of the engine...it might last a decent amount of time.
Same goes for a few other plastic coolant parts.

Nice thing is, with the Tacoma if there's a serious issue there's usually a solution either from Toyota or after market.

 

so how's it going with this? have you progressed?

 

Unfortunately, nothing further.

 

oh well, I'll just chill out and hope nothing bad happens. like with everything else. have a weekend!

 

Any chance of this progressing? Would love to do this when I install my maggy

 

Any word on if the 2022 model year coolant pipes are improved over previous years? My Tacoma is on order, so I was just curious.
