WHAT IS THE PROPER WAY TO BLEED A COOLANT SYSTEM ON A CHEVY

1997 Chevrolet Lumina • 147,000 miles

My car runs hot one day fine the next that is why I want to bleed the systems.

There is a bleeder valve on the heater hose connection at the top of the motor. It has a 7 mm screw you just loosen to allow the air to escape.
