How do I bleed the cooling system?
Expert:  Eric replied 5 years ago.
Hi,

here is the best method to bleed it to ensure no air.

Raise front end about 8-10" to ensure that the radiator and overflow tank are the highest spot as air rises to the top. fill the reservoir, crank engine and turn heater on high and allow engine to run for 5 minutes. Turn off and allow to cool a couple of minutes. Refill reservoir and repeat. do this until the level in the reservoir stays at the full mark after running for 5 minutes. usually 3-4 times will do the trick
