I just read an article that talked about "burping" your cooling system to get the air out of it. Basically, you pop the hood, take the radiator cap off (cold engine only), start the engine and rev it a bit. Not too high, just enough to circulate the coolant. You can have someone else rev the engine while you watch the coolant flow in the radiator. While the engine is running/being revved add coolant to the filler tank (not the radiator directly). Do this for several minutes and watch for "burps" and "gurgles" of air. Be careful because they might belch out of the radiator unexpectedly and splash over a bit.
What else can I help you with?
