Engine Cooling problem
1990 Buick Century 6 cyl Front Wheel Drive Automatic

How would one go about purging the air from a cooling system that has no bleeder valve?

Your Century should have a relief valve on the radiator..but if not..

Remove the radiator cap while COLD, top it off with correct coolant, start the engine, add coolant as necessary until all air bubbles stop escaping. Raising front of vehicle during this procedure will speed up the process. If radiator is already full, just open radiator cap then start vehicle and let it run for 15 mins or so.
