Is there an easy way to bleed the cooling system on a 1994 quad grand am.
if there is can you provide the steps.

hey there, dont quote me on this but as far as im concerned the cooling system will bleed itself, just after your done doing whatever your doing...ex..flushing it, cleaning it, replacing something, just fill it back up and let the car run for about 10-15 minutes and the system will purge itself!!! Good Luck!!!!

No No No No!!!! To bleed the cooling system, let the car idle with the pressure cap off until the thermostat has opened and closed several times. Failure to do this will cause the motor to get an air pocket in it, which will potentially cause severe engine damage, including a cracked head and/or blown head gasket.

Not a problem.

Removing the pressure cap trick usually works but not always. there's a bleeder screw near the top of the engine in the front near the coolant reservor on a metal coolant line. A small wrench, about 1/4 inch, is used to open this about 1 turn with the engine running. This will bleed the air from the coolant system. You'll know there is no more air when there is a small but steady stream of coolant coming out of the side of the valve. Then just close the valve and you're done.
