Bleed The Air:1. Either jack up the front end or put the car facing up on a hill.2. Start up the car and let it warm up so it's @ operating temperature, PUT THE HEAT ON FULL.3. when it's at operating temperature, open the radiator cap, and loosen the bleeder screw. This screw is located above the intake, it's a 10MM and has some japonese writing beside it. You'll see what im' talking about.4. Open the bleeder screw, and pour 50% coolant 50% water into the radiator cap, and watch as air bubbles pour out of the bleeder screw. Fill the cap as much as you see the fluid coming out.5. Squeeze all of the hoses, push them up and down a bit, but mainly squeeze themto make sure you get all of the air out of them.5. After keep doing this until you get only coolant out of the bleeded screw, no air at all. 6. Close the bleeder screw, top off and close the radiator cap, and you're done!

do not pull the bleeder screw while it is running. the car will not shoot coolant out once it reaches operating temp a small burp maybe but no burst. release it to the first notch on the cap and lean the cap to noe side this will relieve the pressure to the over flow bottle then loosen the cap the rest of the way and remove it.

ha ha ha a geyser of coolant. yeah I think you should follow the list pretty much, but when it's up, don't start it, fill until coolant comes out the hole, plug it (don't forget the silicone around the threads of the screw), keep filling until your radiator is full. Then cap it, sqeeze your upper hose and check if your radiator is full again, if not, fill again. Then start and squeeze your hose while you've still got it on. Turn off and repeat the cap part.
