Question about 2002 Pontiac Montana
If you get a constant peculation of air bubbles out the radiator while your bleeding the system than you are likely another victim of the well know head gasket failures that occur on these engines (3.4 liter). All it takes is one overheating and they are done.
I would assume that you are sure the thermostat is working?
