Clearly, this is related to your coolant bypass mod. You don't say, but was it the U-shaped coolant hose mod removing the heat exchanger circuit...
I was thinking about this a little. Basicly there are three things in parallel: - Cylinder heads/blocks - EGR valve - Exhaust heat exchanger...
The independent rear suspension is great until it is damaged and has to be repaired. All of those stamped steel parts, if bent or deformed on...
Toyota USA spec for gen 2 is 5W30, no mention of synth vs conventional. Both are available in that weight. Yeah the coolant losses in 4th gen,...
Not having a Gen-4 Prius but a Prime, I'll have to hold off on the MG1 forced, engine ON threshold. The 41-46 mph boundary was in our old Gen-3...
No matter how often we cover it, people keep on thinking the exhaust heat recovery system somehow involves the catalytic converter. It doesn't....
It's funny though, not 30 seconds in, he says the "problem is the catalytic converter", when the thing that leaks is the EHRS exchanger, which...
This really should be it's own topic rather than tacked onto an unrelated issue in an unrelated forum. That said, if the dealer drained the...
Gen 4 owner here, unfortunately I'm on the same boat, coolant loss, no heat and white smoke coming from the tailpipe. Dealership said its heat...
you could look around for a lower mile 2009 if you liked gen 2. much more reliable than gen 3 if you can find one. 2015 gen 3 might be an option....

It doesn’t need to be that complicated. I am sucessfully running a 4th gen 2018 engine and it’s complete EGR system in a 2011. I simply choked...
Yes, indeed it is the Prime's sprag clutch. What I thought was a non-US market engine is a Prime one. I drove down to Bardstown, KY yesterday...
Thanks. Where would I look for the coolant leaking? Also, I found a 2014 Prius c Four with 58k miles. Super nice condition. Paint finish looks...
*For Informational Purposes Only here, Names and such withheld due to privacy but this car came into our shop this week and I wanted to share some...
Early models? All the way through 2019 it shows. Dang.
The heat exchanger is part of the catalytic converter assembly so you all you are doing is replacing the catalytic converter and then just hooking...
So the TSB came out in 2019 so anybody with older Gen 4's need to be aware of the possible issue...check that coolant level often (at least...
Gen 4 Prius Hybrid can develop a coolant leak in the heat exchanger in the exhaust system leading to hard to recognize coolant loss and eventual...
