Can somebody PLEASE tell me what their 1991 stang runs at with regards to the temp gage. I've been dealing with overheating issues since I bought this car several years ago and have just recently got aggressive in attacking this problem. When looking at the gage you'll see the word "NORMAL" going up and down. My needle kept going up to the 3/4 mark covering the letter "N" of the word NORMAL causing my coolant to flow out of the reservoir (overheat). Since I removed the 4 cats (1 was clogged) and replaced them with 2 magnaflow cats the reading now gets to the letter "O", still at the 3/4 mark. What should the NORMAL reading be for this type of car? Things I've done so far: * upgraded Alternator to a 3g. * upgraded to dual electric fans * upgraded to a 4 core radiator * upgraded battery cables * removed 4 stock cats (1 was clogged). Upgraded to 2 magnaflow cats * removed stock mufflers and went to flowmaster 40's My next and last guess is the Head gaskets on the left side as this is the side that gets the hottest. this was also the side that had the clogged cat. Maybe the gasket was put on backwards or is blown in some manner. I don't have aluminum heads so the chances of them being warped is slim. So again, what should the NORMAL reading be on this type of car?
