Question about 2003 Pontiac Grand Prix
I HAVE FLUSHED AND CHANGED THE THERMOSTAT THE TEMP WILL GO UP TO NORMAL RANGE THEN GO DOWN TO 175 OR SO IT IS A 2003 PONTIAC GRAND PRIX DO YOU THINK IT NEEDS A WATER PUMP AND THE AIR IN THE CAR WILL BLOW WARM AIR NOT HOT AIR.
I dont think it needs a waterpump. what temperature thermostat did you put in? unless the fan is running all the time maybe. i would try another thermostat, the engine needs to be at least 195 degrees to produce decent heat.
