01 grand prix with 170000 mi ( not super charged)..coolant light comes on when I start the car and doesn't shut off right away..but when I put it in gear and move forward it will turn off..doesn't do it all of the time..I have replaced the sensor 3 months ago put a ac delco in it...don't know if it is because it's so hot in Az or what
