Head Gasket (1)

A head gasket is effectively a seal which is essential for maintaining the temperature and integrity of a car’s engine. It is partly responsible for sealing pressure within the engine, as well as the distribution of oil and coolant.

Every time you turn on your engine the head gasket has to operate within very high temperatures and pressures, which is exactly what it is designed to do. The engine of your car needs to be cooled constantly, as it relies on combustion for power and is the core component in performing this job.

If the head gasket is damaged, the engine will quickly overheat, and serious damage will be caused. Overheating in the engine of your car will lead to a loss of compression, the mixing of oil, water, coolant as well as a reduction in lubrication. Head gasket are a hugely important component of your vehicle. So, when they do blow, they need to be dealt with efficiently. But just how much does it cost to replace a head gasket?
