Yesterday I had my thermostat replaced due to an over heating problem. I did some research and did it myself, It is installed correctly, because my neighbors brother is a mechanic and he came over and looked at it while I was working on it and said he was proud. He left before I got finished, anyway, i got it installed and now there is no coolant cycling through the system. I felt the hose coming off of the thermostat and it is full of air, no coolant. How do I get the air outta the cooling system. Thanks for your help.
