4th Gen DIY heat exchanger bypass solution

The ECO mode doesn't change anything about where the hot coolant physically comes from. It just slightly lowers a software limit on how hard the system will blow the heat at you. (It also rules out the use of the supplemental electric heat before the engine warms up—at least in gen 3. As far as I know, gen 4 also has the electric heat and this is probably the same.)

 

thanks!

 

I'd recommand you check your muffler for coolant like Gasket Masters showed in their video.
All you have to do is giggle the muffler and if there is coolant still in there you should hear it sloshing around in there.
There are others on this forum that think the muffler gets hot enough to boil that coolant out of the muffler.

But to me, that just sound like some mechanic double talk to a customers question about what to do with any possible coolant in the muffler.

It's a simple check.

 

My muffler is too serious for that.

 

Just for jiggles, giggle the muffler.

 

Every Prie deserves a good belly rub, just don't do it when it's hot....

 

Is it hot anywhere? gigglin the muffle kin not makin strange Prii sounds nobody's ever heard before. Or is it?
