NEED HELP OVERHEATING
I have a 05 procharged gt great car other than this sudden overheating problem. Ive changed the radiator the stat, waterpump, flushed and burped the system many times, new cht head sensor, the fan i think does not kick on right i grounded it then touched the battery and it turned on so it works. All fan fuses are new. I really dont know what step to take next

I dont have a diablo or anything of the sort i bought the car supercharged and i never got the tuner. I was told without that specific tuner i can never run codes or switch my tune. It takes about 35 to 45 minutes to overheat no matter if ur driving or ideling, once it overheats it pukes all over from the over flow. Thanks for the help i really need it lol!!

what tune are you running? excessively retarded timing will raise EGT's and coolent temps a lot. part throttle cruising you should be around 40 degrees of timing or so. if you're in the 20's you'll drive the temps up and have problems.

The car was programed with a diablo that i didnt get with the stang. I was told without that exact tuner i could not tune my car with another tuner is this true? I dont even know the tune im running. Also yes it goes in the red then sprays all over. Its good for half a hour then slowly creeps up over the next 5 minutes then goes red. I think my fan timing is screwed up and im also going to upgrade my fan.

easiest way to see if your fan is working is to turn on the AC. if turning on the AC doesn't kick on the fan then that may be your problem.
as far as I know (I'm a newb with the tuners) you can reflash your ECU as much as you want. typically you want to download your stock tune into the tuner just in case you ever want to go back to stock if you had to go to the dealer or something. it's also good to have just in case you had an error with your new tune and it didn't work, at least then you can go back to stock and the car will still work.

oh yeah, don't go into boost if you don't even know what tune is in your car!
even if you have to buy a whole new tuner and a tune from one of the reputable venders on here it's cheaper than a new motor! who knows what the car is doing in boost on the tune that's in there and you're already having problems. all it would take is a little too much timing to pown something, not worth it!
