problem #4

Grand Prix 3.1L V6

  • Automatic transmission
  • 140,000 miles


I have a Pontiac Grand Prix with a random overheating problem. The water pump, and thermostat have been replaced. The cooling system has been flushed. Some days the vehicle runs fine. Other days the vehicle will overheat. There are no signs of coolant in the oil or vice versa. I have bled the air out of the cooling system using the 2 bleeder screws. Could this be a Dexcool problem causing blockage that would not allow proper circulation?

It begins when I turn the car on. If the light on the dash that shows what gear the car is in, isn't lighting, then the issue is present. With this lack of light brings on the gear sticking in park, the air conditioning not working, and my car overheats due to the fans not kicking on. Note: the keys will come out of the ignition with the car running.
