Q: My car is overheating the oil is not milk there no leak outside of the car and the coolant is still in the radatior

A leaking head gasket is not the most likely cause of overheating. And, if combustion chamber exhaust gases are leaking into the coolant, there are tests that can be performed to rule the head gasket in or out as a cause. The most common causes of overheating include low coolant level, a faulty thermostat, a plugged radiator, a faulty radiator pressure cap, collapsed hoses, non functioning cooling fans, and a faulty water pump or drive belt. Certain engine faults, such as poor engine running condition, and exhaust blockages can also cause overheating.
