I got a 3.8 Liter, 92 PA, here is what is going on...
When Start the car it will warm up to normal temp. However, when I start driving the temp drops to the lowest gage setting. As long as I am on the highway, driving around in the city I have to turn the fan on with a switch that I wired inside the car to keep the temp from going too high. When I bought the car the coolant low light was on. Have had it checked several times and no one seems to now whats wrong! I think that problem and this are related some type of way. How bout some insight?
