01 sunfire se coupe cooling system.
I have an 01 Sunfire SE Coupe, new head gasket,
water pump, and radiator. Car has heat, it ran fine
for 2 days, now it overheats and won't cycle water.
When I loosen reservoir cap, black/green water
come out of overflow tube. (i know green is
antifreeze) please help, car has been down for 2
months. Has 2.2 motor
