20701803 Cylinder Head for Volvo FH12 D12C

What does a compressor cylinder head do?

This cylinder head serves as a vital component within the air brake compressor, managing the combustion or compression chamber environment to maintain consistent pneumatic pressure. Manufactured with high-strength components, it is engineered to withstand the thermal stresses and high-pressure cycles inherent in heavy commercial vehicle braking systems.

Compatible Volvo FH12 engine fitment

This specific part is compatible with Volvo FH12 trucks featuring D12C engines, including variants such as the FH 12/500, FH 12/340, FH 12/460, FH 12/420, and FH 12/380. It functions as an OE-equivalent replacement to maintain original equipment performance standards.

Installation and maintenance guidance

When performing compressor maintenance, technicians should inspect the cylinder head for any signs of surface erosion or thermal cracking. Proper installation involves verifying that all sealing surfaces are clean and that the mounting torque meets specification to prevent air leaks within the braking circuit.

Troubleshooting air pressure issues

Regular inspection of the cylinder head helps prevent sudden loss of air pressure in the vehicle's pneumatic system. If compression levels drop or air consumption increases, checking the integrity of this component is a recommended diagnostic step.

OE cross-reference

13 01 10 (Compressor Cylinder Head) is the equivalent of the Volvo OE number. This part directly replaces Volvo OE number 20701803.
