i think you misunderstood me,, i agree with you 100% about the air bubble,, there is nothing inside the new motor that can cause this, it can only be some trapped air or the new water pump is defected and i really don't think it's the pump because it would continue to get hotter & not stop a little over half on the gauge, i was just agreeing with you that it is a simple water bubble,, i think i am goung to bring it back to toyota dealer who installed the motor and have them burp it because they used that high dollar super long lasting pink toyota coolant since i already payed them,!! i know the question will be asked, why a toyota dealer rather then dodge,? because my son works there and i got one hell of a deal on the swap,
