Question about 1999 Pontiac Grand Am GT
I have a 99 Pontiac GrandAm GT, 3.4L. I have done a radiator flush, put in a new thermostat, coolant temp sensor, and new water pump and I am still overheating. I have looked very closely and do not have a blown head gasket. I only get heat out of my vents when my car is in park and I am holding my throtle at a steady 2500 RPM's. What else can I do to fix my car?
I had the same exact problem(s). My problem was blown intake gaskets. I had a mechanic look at it. He raised the hood and said "simple, you have blown intake gaskets". My car does not overheat now, even though V6 does run about 200-215.
