OVERHEATING

1999 Pontiac Grand Am • 3.4L V6 2WD Automatic • 120,000 miles

Have replaced both thermostat and water pump. Tried flushing air out of bleeder screw but have only located one on passengerside. Where is second one located?
Found leak on new pump so replaced but still have overheating issue. Heater does not blow hot air.

Have apro check for a blown head gasket, will need to be pressure checked so system will need to be full. You are probably low on fluid.
