Go to advance or autozone and buy an air bleed system. This is the easiest and only way to truly get all the air out.

There should be a brass bleed screw on top of the thermostat housing on the front drivers side of the engine where the coolant hose comes out and goes to the radiator. To bleed the air out, unscrew the 7mm top section while the engine is running until bubbles start coming out. Let it run until it stops bubbling and only coolant comes out, then tighten the 7mm top screw BY HAND(if you use a wrench to tighten it, it will break very easily). I usually just use a socket by itself so I can turn it easily without over-tightening it.

Dorian, you are right on the location of that bleeder valve but you are forgetting the bleeder valve by the water pump. you have to bleed the air out of the bleeder valve by the water pump first, then you can bleed the rest of the air out by the bleeder on top of the thermostat housing.
