My 1994 Grand Prix recently overheated. I removed the thermostat and tested it in boiling water. It was bad, so I replaced it. Now the temp guage reads between 150-225 while driving and moves toward the red when stopped. When you accellerate, it comes back down. The water pump looked fine. Is the sensor the likely culprit, or is there something else I need to check?
have the same problem?
