Your engine generates a lot of heat—and it’s the cooling system’s job to keep that heat under control. When everything’s working properly, coolant flows through the engine, absorbs excess heat, and cycles it away through the radiator. But when something fails in that system, temperatures rise fast—and the consequences can be serious. Ignoring cooling system problems doesn’t just put your radiator at risk. It can lead to major engine damage that’s expensive to repair. Here are six engine problems that often result from overheating caused by cooling system failure. 1. Blown Head Gasket When your engine overheats, one of the first components at risk is the head gasket. This crucial seal sits between the engine block and cylinder head and keeps oil, coolant, and combustion pressure separate. If temperatures spike, the metal surfaces can expand unevenly, compromising the seal. Once the head gasket fails, coolant can leak into th ... read more
