Engine Mechanical problem
2000 Pontiac Grand Am 6 cyl Front Wheel Drive Automatic
I have had overheating problems after changing waterpump and thermostat still had a little problem but seemed to be ok. Two weeks later while driving heard a strange noise and it started to get hot. When I pulled over the engine died and the coolant tank was empty the engine will not start. I pulled the intakes the top intake had water. Drained the oil it is dark brown with a few bubbles. Could the head gaskets need changed also. How do I tell if head is warped.
