For the last year I have been having a slow coolant leak and both the Ford dealer and I can't find out where it's coming from. It seems to be only leaking when the car is turned on and there is pressure in the system. At first the leak was only occuring in the winter and it wouldn't leak at all in the spring fall and summer, but now it's happening in the winter as well. It's been pressure tested three times, had the plugs inspected, and been inpected by me. I can see some coolant on the bottom of the radiator, and other places under the car but it's so little of anything that I think it is just being sprayed around when the fan kicks on? Anyone else with this problem on a 94-95 stang or cobra? Any suggestions appreciated.
