Need Help Quick!

I tried searching but I don't have time to dig through 57 pages of coolent questions. I'm replacing my radiator (the thermostat and hoses are fine, I just had an inch long crack on the tank that coolent was seeping out of.) and need to bleed the air out. How do I do it properly and where is the bleeder valve/screw.

Thank you

bleeder screw is right above the upper radiator hose where it connects to your engine. your manual will tell you the correct way to bleed... but

take of rad. cap
loosen bleeder screw
and fill radiator until you see no more bubbles.
Before you start filling up the radiator, turn your key to the "ON" position but don't start the car and put the heat on full blast.
Do this:
first turn the heat to full hot(opens the heater control valve to let hot coolant flow into the heater core). Do this with the ignition on, engine not running.
1. Open bleeder at thermostat housing.
2. Pour coolant into radiator until a steady stream of coolant without bubbles comes out bleeder.
3. Close bleeder.
4. Leave rad cap off and start engine. As engine warms up top off coolant as air burps out.
5. Massage upper radiator hose to help get air out.*CAUTION COOLANT IS HOT AND WILL BURN YOU* if you squeeze the hose too hard and coolant splashes out on your arm.
6. When engine reaches normal temp it should be good to go. Install radiator cap.
7. fill coolant resivoir to proper level.
8. Drive vehicle and monitor temp. After engine cools down completely remove rad cap and top off if necessary.
