engine over heating
I was driving my 01 grand prix i had just bought and as i was drivin the temp gauge started
goin up and then back down when it would go up the heat would turn cold and when it
goes down the heat comes back the temp gauge finally went up to far so i pulled off and
bought some coolant the temp light came on but after shuttin down and letting it cool
down i filled the radiator and the car ran fine but the temp gauge is still goin crazy
