1999 Pontiac Grand Prix Owner Comments

problem #2

Grand Prix GTP 3.8L V6

  • Automatic transmission
  • 205,000 miles


Car would constantly over heat, especially during the warmer summer months (from Northern Indiana) to the point where if I was sitting at a light for more than 30 seconds, the temp would rise from normal into the red. I would have to turn my car off during these times to help keep it cool. Did a bit of research and the first suggestion was the radiator. Figured this was the culprit, so I replaced both the radiator and fan myself. Not sure the cost for a shop. Car ran okay well for about a month afterwards until I discovered the LIM gasket was shot as well.

I HATE THIS CAR. i am never everrrrrr buying a Pontiac grand anything ever again. When people ask me "whats wrong with your car",i cant even think of whats NOT wrong with it. The temperature light ALWAYS comes on, and the temp. usually goes up when idle, at a red light; usually goes back down for awhile while driving. Everytime I drive this car, i think its gonna be the last time i'll be able to drive it. My car turned off at a red light once. It sounds awful when i drive it.
