How to Bleed the Cooling System on a Chevy Cavalierby William Hall
Bleeding your Chevy Cavalier's cooling system is one key to ensure your car's longevity. Overheating and clogging will not be a problem once your car's circulation is improved.
Start at the furthest point of the actual cooling system supply. For any car, this would generally be at the heater core. This is usually under the dashboard at the place where the hoses hook together and come through the firewall.
Locate the two hoses going through the firewall into the heater core.
Disconnect one of these with a screwdriver.
Have someone else start the engine. Make sure the loose end of the hose is pointed towards the ground
Make sure the heater is on. Turn it on at the dashboard, just like you would in the wintertime.
Wait for water to start circulating and it will push the air out of the loose hose.
Put the loose hose back on the heater connection once water starts running out to keep any air from reentering the system. Just push it back onto the heater connection where you removed it. Have someone turn the car off and re-tighten the screws.
- Some heater cores have squeeze-type clamps around the hoses instead of screws. A pair of pliers will be needed to disconnect the hose.
- This method also works for bleeding the brake system.
