overheating at idle
The car has 240k and I just replaced the cracked radiator and new thermostat. The fan clutch is fine and the high heat hose is fine. It doesn't leak any coolant and none of my hoses are cracked or worn. It keeps a decent temperature while the rpms are kicked up but at lower rpms or at idle, it immediately begins to overheat. I'm thinking water pump but has anyone heard of those impellars getting worn to the point where they slip like that. Is there some kind of in-line pressure release valve orsomething i should be looking for? Don't wanna replace the waterpump if I don't have to.
