Crown Vic Overheating
I have a strange overheating problem on my 2008 Crown Vic. 1st episode I lost all electrical accessory power and then the car died. Symptoms resembled a battey drain after an alternator failure. I jumped the car off and it ran fine , no indication of overheating at this point. Second occurance I stopped and put car in park when attempting to continue driving gear shift would not move at all. I turned the vehicle off and attempted to start but it sounded like a dead battery. I jumped the vehicle off and again no further problem. I parked the car and tested the alternator and battery both passed diagnostic tests. At the same time I tested the antifreeze and it only tested good to 20 degrees F. I flushed the system with new collant and had no further trouble until the next day. Once again I lost accessory electric the a/c shut off and the car overheated. I got the car to a mechanic and left it over night. The next day we topped off the collant and ran the system, the fan checked okay on both speeds and the car ran at normal operating temperature even after driving the car several miles with and without a/c. Please help I am stumpped.
