  Engine Cylinder Head Gasket, Gasket Cylinder Head

• Description:

  The head gasket (11044AA642) seals the cylinder head to the engine block to protect the engine valves, crankshaft, pistons, and other components. These gasket seals also prevent motor oil and coolant from leaking and going inside the cylinder block, allowing the coolant to flow smoothly to other parts of your engine.
  

  Head gaskets are constantly exposed to extreme temperatures, pressure, and other elements like water, oil, fuel, and exhaust gases. If your car is constantly overheating, it can lead to a blown head gasket. A faulty head gasket has numerous indications, including oil or coolant leaks, white smoke emissions, and bubbling in the radiator and coolant reservoir. The dipstick may also have brown or bubbly oil and traces of water. We advise that you constantly check your gaskets to ensure they are in good working condition.

  SubaruOnlineParts stocks original head gasket replacements for select Subaru vehicles. These gaskets are compatible with 2.5L H4 engines and gas transmission systems and are sold for less than the manufacturer’s suggested retail price.
