OK. Here goes. I have a new water pump that is working great, with help I got to see that it is working. I took the car down and had it flushed out, drove the car for 5 days and worked great. On the evening of the 5th day I stopped to get a wash and the car started to heat up a little bit and the heater blew "cold" air! The car never heated up before. I thought ok the cleaning may have messed up the thermostat, so I put a new one in and still cold air. all hoses hot but the one at the core. I seen that the overflow was not moving, I when and put a new one on. I have heat and the back hoses are now getting warm. BUT, the heat is not hot like it was, I paid to have the total system flushed, that included the core. How to do I get all the air out of the system? If the system is clean then this can be the only problem left, other than replacing the core. Has anyone done this before and knows how to get the air out?
Many Thanks
