i wouldn't hesitate. they've had a few issues, but nothing major. i think the worst thing is the leak at the exhaust heat exchanger for the...
Well, they said it's ready to pick up. It's not the heat exchanger they said - they checked the EGR valve. Had it under pressure for a few days....
There was never any recall, just the TSB that explained the symptoms to look for and remedy (replace the forward CAT with the heat exchanger)....
You're overthinking it. Yes, that hose runs from the exchanger into the engine. You can also point to the hose where the coolant comes out of the...
Air never gets in there either. Even though the ICE is 'liquid cooled', you do need some air flow for heat exchange. ;)
Besides, even if the valve did shut off coolant flow through the heat exchanger, it wouldn't block both inlet and outlet tubing, so you'd still...
how is the coolant level? have you dealt with a leaking exhaust coolant heat exchanger? you'll need a boroscope to check the head gasket. if the...
Nothing other than a head gasket replacement just recently. During this job, I replaced the water pump, thermostat, spark plugs, coolant and...
Hi!2017 Prius I do have a coolant leak,dealer says is from my Exhaust Heat Recirculation System.The problem is that part is quite expensive and if...
You are lucky. Dealer broke my engine (at 46K) for incorrect diagnosis of this issue.
The base 2019 Prius still has a spare, that’s the only one I’d consider. 4th Gen had coolant leaks in the exhaust heat exchanger, which if...
With forcing the valve to remain closed, the coolant will not enter the heat exchanger and therefore not leak inside. Maybe, this could be an...
A 2015 Prius is a Gen3 and is known to have engine problems. Since you keep cars a long time, go with a 2016-2022 Gen4, The only known problem in...
There's a TSB for a coolant leak into the heat exchanger but you may be outside of it by mileage. It effects some early gen 4 model years. There's...
check system fuel pressure first. fuel filter sock may be clogged. you should be able to borrow a gauge kit from any chain auto parts store. also...
Well, the Gen 3 and Gen 4 heat exchangers do look rather different. They seem to have a different supplier or just a different design. And...
Yep, it was the heat exchanger and the pump was all good, working as expected.
In the real world, getting houses too tight is not a problem. (especially if you are worried about cold windows!) Most houses that were built...

Any car will blow a head gasket if it overheats and there is no easier way to overheat than to leak coolant out the exhaust from a cracked gen4...
