Karcher Pressure Washer Cylinder Head

Description

The cylinder head helps in cooling and combustion for your pressure washer

The combustion chamber, valves, spark plugs, and cooling channels are all housed in the cylinder head of a pressure washer's engine. It supports key engine components, allows air and exhaust movement, and helps in chamber sealing. 

Its cylinder layout guarantees effective cooling and combustion for the engine.

What causes damage to the cylinder head?

The cylinder head in a pressure washer wears down with overheating, damage on the cylinder head gasket, incorrect torque settings on the head bolts, engine detonation, and contamination from debris or contaminants entering the engine. 

These issues can lead to a damaged seal, reduced compression efficiency, leaks, and decrease in the engine's overall performance.
