What is a cylinder head and how does it fail?

Cylinder head cracking has become more common as car manufacturers use mixed metals in their engines. Many vehicles, for example, have a solid cast iron engine block but an aluminium cylinder head. These two metals expand at different rates, and this can lead to cylinder head cracking.

The most common cause of cylinder head cracking is overheating. When a vehicle overheats, it puts stress on all of its metal components, including the cylinder head, which is often at the center of the heat. This can cause the head gasket to fail, which may lead to cylinder head cracking as the components warp and pressure begins to leak. All drivers should properly maintain their vehicles to prevent overheating.

Many drivers mistakenly pour cool water into the radiator when their vehicles overheat, in an attempt to bring the temperature down. This is not a good idea, because the rapid temperature change will cause cylinder head cracking due to thermal stress. In a case where the cylinder head survives overheating, the driver may inadvertently destroy it by trying to do good.

To prevent overheating, make sure that your radiator is filled and in good condition, with a tightly sealed cap. Check to be certain that your engine thermostat is in good working order, and accurately reflecting the temperature. Make sure that you have no stretched belts or leaky hoses, and that the fan is working effectively. If your car does overheat, stop, turn off the engine, and allow it to cool completely before adding water.

Cylinder head cracking can also be caused by localized hot spots in the engine, which usually represent a failure in some portion of the cooling system. Always make sure that hot spots are addressed, particularly if your head gasket has failed and required replacement recently. Hot spots are often caused by uneven expansion of engine parts, leaky hoses, and pre-ignition in the cylinders of the engine.
