Same problems. I replaced the coolant temp sensor, new thermostat, new coolant level sensor, flushed and filled the system.. my gauge still goes all the way up about 10 sec after I start the car and I still get a low coolant level light too... I dont know what to do next.. any ideas??
I just got a 2005 Grand Prix and the temperature gauge was going over half and a lot to red. I changed the radiator and thermostat. It is still doing it any suggestions?
