My 3.8L mustang is overheating and I don’t know what is causing it. I have replaced the thermostat, water pump and radiator and it still is overheating. I believe it is the heater core because I don’t get hot air and the heater core hoses don’t get hot air, also I did an oil change recently and the engine oil was hot after letting it sit for 30 minutes . There is no signs of the head gasket being bad because there is no milky presence in the coolant and the engine oil other then it smoking...
