Air Conditioning problem
1986 Buick Skyhawk 4 cyl Front Wheel Drive Manual 172000 miles

My car starts to overheat when the air conditioner has been running for a bit. Even when Im driving and not idling. I just put in a new thermostat and the fan is working. Once I stop and turn the car off I can hear the coolant boiling in the overflow area.

Could be airlock in the system try bleeding it -if not check for a clogged-up radiator and defective water pump if okay get it block and pressure tested.
