COOLANT REPLACEMENT

2002 Pontiac Grand Prix

Engine Cooling problem
2002 Pontiac Grand Prix 6 cyl Front Wheel Drive Automatic 107000 miles

I have to replace coolant in my car every 3 days. The temperture gauge doesn't indicate that it's hot, there are no leaks. Could this be a thermostat or water pump problem?

It is either leaking it or burning it, is it blowing puffs of white smoke out exhaust?

First perform a compression test, if OK, then pressure test the cooling system.

If compression test shows 1 or 2 low readings, the do not perform cooling system test, you have a bad headgasket, intake gasket.
