I got a 96 GT with an overheating problem, which has to be taken care of as its my daily driver, I live in Cali and hot days are now present. OK , so this is what happens. My stang started overheating and the gauge used to go at about 3/4, until the fan turned on. I recently bought a SCT programmer, and the first thing I did was to lower the temperature in which the fan truned on. I put it at about 187, and the 2nd speed right after it, at about 190.
Now I dont really have trouble as my fan turns on at a good time, and in hot days the gauge barely passes the middle. THe huge problem is that I live in LA and I really love to be able to turn my a/c on. Thats when my nightmare starts. After a few minutes of running my car, my baby gets so hot that it almost reaches the RED!!!! :angry4: And with the fan even in the second speed it doesn't get lower, until I turn off my a/c.
The water pump in my stang was changed about 1 year ago because the other one was completely bad, just a few months after purchasing the vehicle from a car lot ( vehicle with 98xxx, bone stock, and one owner). It was changed for a new one from autozone. I had never noticed any problems as I bought the car on winter and I never used the a/c, only to see if it worked. After looking at the impeller design of a 00 stang, I decided to get it and see if that could solve the problem.
Before I go any further these are most of the mods that my car's engine has : cold air intake, bbk shorty headers, flowmasters, underdrive pulleys, SCT programmer (used a pre-loaded tune and no changes to timing), all aluminum 2 core radiator.
The car still has two cats per bank ( Thanks C.A.R.B. :angry7: ), stock H pipe, stock fan, mr. gasket 160* perf. thermostat, and my engine has never been rebuilt before. Also it doesn't throw white smoke. The radiator is almost a year old, so not too old, and as I said before new water pump from a 00 stang ( everything was the same but the impeller and the little shaft sticking out). I also flushed my cooling system about 2 months ago.
Any suggestions would be greatly appreciated, and even though I think it is pretty hard to find out what could it be, I'll be great to see if anyone has had this problem before. If you can't think of anything, still thanks a lot for reading!
