why do I hear boiling water after I turn off my car?

normal as always. toyota said something about an acu motor? something to do with the amount air regulated for the throttle. He said its going bad. When he tapped on it the rpms went back down to normal. He also told me it would run almost 300.00 for the part....I just paid 5000.00 to have the engine replaced :(

WOW!!! I was under the impression that you were doing the work yourself. I'd be bringing it back to the shop that installed the engine andhave them double-check their work.

Ziptie 12 is an idiot.

Actually. My radiator. Cap was bad. No m ore boiling water: )
