Had a similar problem with mine. I was told to drive it at full throttle for a few seconds to push the coolant throught the system faster. It did take care of the problem. However, make sure you take extra coolant with you. As the air reaches the reservoir it will pull coolant into the system and possibly throw your low coolant light.

I thought I got all the air out of mine but didn't. Try my suggestion above and let me know if it worked.

foster, you have to drive it a little while, and then add more coolant like gotdesl said

"Drive it a little while". Throw it to the floor and wear it out.
