Hey forum,
I have noticed a constant problem with my 99 Grand Prix Gt 177,6XX miles on it ever since i did a coolant flush and change. B.T.W. I am running with Advanced Auto Parts brand dexcool in it if that matters any. About every 2 weeks or so the Low Coolant light comes on. I have checked for leaks at the elbows...no leak there, i looked under the car while its running...nothing dripping, it was leaking at the thermostat housing but i fixed that with some southern engineering. I haven't done a compression check to test the head gasket because those almost never let go, the oil looks fine no milkshake just dirty, I checked the UIM best i could and didn't see anything out of the ordinary. The car isn't overheating even in the triple digit texas summer heat. Quiet frankly i'm at my wits end with were its leaking at. I will check the UIM tommorow again to make sure. Any help you guys can offer will be much appreciated.
Thanks in advance
