Good morning. I have a 96 Mustang Gt with about 70,000 miles on it. Runs great. 2 weeks ago I put a new OEM intake manifold on it to replace the old one that ford has had problems with. Everything is hooked up right and no leaks. My car does have a hypertech power module on the computer so I've always had a hypertech cooler thermostat to go with it. I used to run the 160 degree but put in a new 180 degree thermostat. Now, when my car warms up the cooling fan turns on and stays on all the time and seems like its in "overdrive" mode because its moving at a very high speed. It doesnt shut off until I shut the car off. Now I know that if you run a stock thermostat with that power module that this will happen and thats why they recommend you use a cool thermostat but Im confused as to why this is happening with their 180 thermostat. Should I maybe take power module off and let the computer reset then put it back on? Any help would be appreciated. As I said before I double checked everything and its all hooked up correctly. Thanks guys.
have the same problem?
