2007 pontiac grand prix running hot
Hello. I recently bought a 2007 Pontiac gram 3.8
engine not supercharger. My car is running hot
within 10mins. I have replaced water pump,fan on
car, and thermostat... I also took the thermostat
out and drove car it still ran hot but water is always
in the coolant tank but radiator be hot and full of
pressure. I was wondering what could be the
problem???
