Okay so I'm having cooling issues with a 4AC AE82 I have. A few weeks ago it got really hot and caused a heater hose to split. I assumed it had gotten hot because of this leak, so I replaced the hose. But the car still got far past operating temp when driven. I have checked for other leaks, replaced the thermostat, replaced the radiator cap, and re bled the cooling system with brand new coolant. None of this have fixed the problem. The only other thing I can think of would be the head gasket, but there is no coolant in the oil, and if coolant was leaking into one of the cylinders, wouldn't the coolant level get lower? Because the level never drops even by a tiny bit. Does anyone else have any idea's or diagnostic tests I can do to sort this. It's pissing me off! Thanks in advance.
