Possible overheating problem 1995 Ford Crown Vic small V8


#1

My temp gauge runs to the high end when I run my AC in hot weather. It has not gone into the red yet but comes very close. I have replaced the thermostat, fan clutch and temp sending unit. I have also put a thermometer on the radiator hose to the block and it does not get much higher than 200 degrees. This leads me to believe that the gauge has gone bad but I don’t know that for sure. Doe anyone know how i can test the gauge to determine if it is a bad gauge or do you have any other information that could solve this problem.

If the temp gauge moves up from normal to hot, SOMETHING made it do that and I suspect it was heat…It might be time for a new radiator…


#3

How many miles are on the car and when was the last time the radiator was flushed?


#4

It seems you did everything except unclog the radiator. It is likely not coiling the way it should. As per our other poster, it’s probably time for a new rad. That may have been your only problem!!

A good shop would have been able to diagnose the problem, and the whole fix would likely have cost you less than it will now.


#5

It could also be the water pump, but checking for a clogged radiator (clogged in terms of water or airflow) would be the first thing to do.


#6

Does the temp gauge go down dramatically if you turn the heat on?
