2000 chevy malibu 3100October 26, 2015The car is running hot i put a new intake gasket on it and took the thermostat out why is the car still running hot Keywords:Malibu 1 thought on “2000 chevy malibu 3100” Freeautomechanic October 27, 2015 at 9:50 am Taking the thermostat out will cause a car to over heat. Since you already have it out why not test the thermostat. Quick test by placing the thermostat in a cup of Hot water and watch to see if it opens. then remove with pliers, so you don’t get burned, and watch for it to close when it cools down. Then put it back in the engine. Engine Overheating Troubleshooting Comments are closed.
