Question about 1999 Pontiac Grand Prix
I have a 99' Grand Prix. The temp guage needle moves up and down suggesting it is getting hot. Fluids are full. I thought about changing the temp gauge sending unit and flushing. Is there another answer?
Have you been adding coolant ? if the level is low you can experience this problem , or it could be a thermostat thats getting to the end of it's life !
