13 30 12 Compressor Cooling Plate for Volvo & Renault

What does a compressor cooling plate do?

The compressor cooling plate serves as a critical intermediate component situated between the cylinder block and the cylinder head of an air brake compressor. Its primary role is to transfer the heat generated during the compression process into the cooling circuit, whether via water or air channels. By effectively managing these thermal loads, the plate protects the valve plate, piston rings, and gaskets from premature wear.

Compatible vehicle models and engines

This heavy-duty cooling plate is specifically designed for fitment in Volvo FL, B8R, B5LH, and FE models featuring D5K, D8K, or DTI engines. It is also suitable for Renault Trucks D series with DTI5 and DTI8 engine configurations. These components are engineered to be compatible with Knorr-Bremse systems found in various heavy commercial vehicle applications.

Installation and maintenance guidance

For workshop technicians performing an overhaul, it is essential to inspect the cooling channels for blockages and verify the flatness of the sealing surface. Replacing the plate during a compressor rebuild ensures a reliable seal between air, water, and oil channels. Proper installation prevents air leaks and maintains consistent pressure within the pneumatic braking system.

Preventative maintenance benefits

Maintaining a stable operating temperature through high-strength components helps extend the overall service life of the compressor assembly. Regular inspection of the cooling plate during scheduled maintenance intervals can prevent more significant system failures.
