temp gauge topped out into the red zone when at an idle. thought it was a relay or bad fan. shop trouble shot to a leaking water pump and replaced the water pump and did a coolant system pressure test, flush and fill. Two days after I got it back, it showed signs of coolant leakage (it has never had any leaks in the past) and now the radiator is wet at both corners and coolant is dripping.
Overheating, replaced intake gasket, freeze plugs and hoses. Still overheating, bled the lines. Seemed to help but the next morning was overheating again.
Engine Coolant light has came on for twice in two weeks, I've replaced it every time the light has come on. However, it seems that there is a leak somewhere between the reservoir and the radiator.
