Ever since I installed my headers, open element filter, and flowmaster cat back exhaust, my 92 camaro over heats!!!! The only way the temperature goes down is when I turn on the AC with the fan on. I replaced my air dam, but with the same problem. I even changed to a thicker oil, but to no avail. With all the new bolt ons, could it be my timing????

 

If turning the AC on cools your car, that shouldn't happen usually AC will warm a car up. I would check to make sure your fans are coming on properly.

 

same with me. I will be putting a lower temp FAN SWITCH in when I swap my 'new' used LT1 cam in...

 

check to make sure you didn't knock the fan switch connection off when you were installing the headers, the fan switch is located on the passenger side head between #6 and #8 spark plugs.
