ok.. lets see i started noticing my car temp gauge hitting 270*degrees and then it would shout back down to normal. Iv changed the radiator i thought i was leaking from my overflow tank but i replaced the hose new hose clamp. Mind u if i was hitting 270* there should be smoke coming from the engine none. No white smoke from my exhaust so i dont think its a blown head gasket. Im thinking it might be my heater core or water pump but i think if it was my water pump it shouldnt not work then work it should work or dont. iv replaced my radiator cap to. as im driving and i put the defroster on it will start to blow hot then will go cold. but once i turn it off it will still run 270* . but i check the radiator it has coolant in it but the overflow tank will be completly empty. no leaks on the ground and iv had 4 people look at it with the result of it coming back idk. i dont want to keep spending money i want to fix my ride shes my favorite stang but if i cant figure it out i will end up selling it getting another one please help!!!!!!!

THANKS COURTNEY

Have you checked to see if your heater core isn't leaking under the carpet. You definitely have a leak somewhere. Find it.

No.Tomorrow I'm going to have my dad pressure test it to see if its the cooling system but they think if it doesn't show there that its a blown head gasket.
