Set heater on high, keed car running. Some recommend running the car with the radiator cap removed until it stops bubbling. Another suggestion is to remove cap from recovery tank and squeeze upper radiator hose a few times after coolant is up to temp (car still running). Others also combine this with having the front of the car on an incline or jacked up. The proper way is to use the bleeder screw(s) on the front of the engine. A post I read a long time ago said to run with open bleeder screw until coolant comes out. Another said to attach a hose to bleeder and run until no bubbles in coolant. Regardless: If you use the bleeder screw be careful. It is brass and VERY easy to bust the screw head off. Voice of experience here. Go easy with it when opening.

there is a bleeder valve just behind the water pump. it takes a 1/4 inch socket or wrench. start the engine then loosen bleeder this will allow the fluid though your system. when you get fluid coming out without air you should be set. good luck.
