Q: Car overheats

asked by on

My car is overheating.

Overheating can be caused by something as simple as low coolant level, or something as major as a blown head gasket, or a crack in the cylinder head or block. The cooling system should never be checked if the engine is hot, or the cooling system is pressurized, or serious injury could occur. The cooling system needs to be pressure-checked, and the coolant circulation of the water pump verified. The engine oil will need to be inspected for coolant intrusion. Based on these checks, the course and scope of repair can be determined. You may want to enlist the help of a mechanic, like one from YourMechanic, who will have the training and equipment to accurately diagnose and repair your car’s overheating issue.
