Cylinder Head Gasket
Various car manufacturers produce their own head gaskets for the particular makes of their automobiles. So whatever your car's needs are, there's a head gasket set just for you.
Time will come that your head gasket will leak or blow. Symptoms of these include coolant in the engine oil, engine oil in the coolant, and overheating. If the cause is overheating, the thermostat, radiator, water pump, and EGR system should be checked to determine why the engine got too hot.
Always remember, when your head gasket fails, a replacement head gasket should immediately be installed. Head gaskets fail due to various reasons, which includes the design of the engine or the gasket itself, installation errors, and as mentioned, overheating. Replacement should immediately be done before the radiator gets damaged further, as a damaged head gasket transfers cylinder heat and pressure to the cooling system, blowing up the radiator.
