I have a 2001 2.2 engine sunfire. I was leaking antifreeze for a long time and a friend put the blue devil sealant in (which now I know that's a bad idea) but it worked for a couple months.

Asked by Sara Sep 26, 2014 at 04:25 PM about the 2001 Pontiac Sunfire

Question type: Maintenance & Repair

We replaced the radiator, water
pump, the fan sensor, and a few
different thermostats, and flushed the
heater core. The car had a 195
thermostat but factory only makes
180, which we replaced. The car
continues to over hear with the 180
thermostat. We hollowed out the
thermostat and it's not overheating.
Several tests were done on the head
gasket and that was ruled out! What
else could it possibly be!?!!!?

It could be the intake gasket or the head itself. When it was leaking anti- freeze was it internal or externally leaking?

So we have a 2002 Pontiac Sunfire, 2.2 litre. Bought the car, used it not even 24 hours later the battery light came on, did a multimeter test, showed the alternator was bad, bought a new one and changed. Worked good for approx a week. Now the battery light comes on and off. When the battery light is on, the wipers are slow, the stereo quits working, when idling the rpm's will drop down and before stalling jump back up, all the lights on the dash will light up (battery, abs, e-brake, airbag etc.), the speedometer and tachometer will quit working also. ANY IDEA WHAT THIS COULD BE??? 3 Answers
