So over the past 6 months I have had to have 3 water pumps replaced , as well as the HVAC system serviced due to no coolant or a line popping off after the water pump being replaced. In 13 months we have had the vehicle serviced for the same thing 5 times, all under warranty. All by the same Ford service department. We bought the truck with 12k on it and it now has like 32500 on it. Any suggestions on what could be causing the over pressurization of the system? Any suggestions on what the next course of action to take is? I don not want to have to call Ford Customer service , as it would look badly on the dealer service department, and they have been super helpful with our other Fords. I have requested the Service Department Manager have a look at the case and its issues. Thanks in advance for any suggestions.
