Re: 1990 crown vict. wagon
I can't really describe the banging sound, I know its when the car is driven quite a bit and then upon stopping you hear it. I don't know whether it's coming from the thermostat or possibly the heater core. I had tested the coolant mixture and it is fine. I had also ran the heater of the car in case any air was in the coolant system. Any ideas would be greatly appreciated.
