product presentation

The block and cylinder head are often made of different materials. In order to seal them together, a cylinder head gasket (often called just the “head gasket”) is installed between them.

The head gasket is very flat, and usually made of metal coated in other materials. Most modern engines use a multi-layered steel (MLS) gasket design. The gasket has many holes in it: a large hole for each engine cylinder, and smaller ones for the cylinder head bolts; oil passages; and coolant passages.

Confirming the existence of a head gasket leak usually involves specialized testing by a professional, and can sometimes require disassembly of the engine. A cylinder head gasket can also leak in many different ways, exhibiting many different symptoms. The most common symptoms we see that may indicate a head gasket failure are:

Air bubbling in the radiator, which doesn’t seem to go away no matter how long the system is bled for.
The vehicle violently expells coolant; blowing it out around the radiator cap or coolant reservoir.
The cooling system shows signs of excess pressure build-up, such as a cracked radiator side tank or blown hose.
The engine overheats very quickly, such as within a couple minutes of driving from a cold start.
White smoke from the exhaust.
There is coolant in the engine oil, or engine oil in the coolant
