11 33 32 Cooling Plate for Detroit Diesel DD15 Engines

What does a compressor cooling plate do?

This compressor cooling plate serves as a vital intermediate component within the air brake compressor assembly. By carrying heat released during the compression process into the cooling circuit, it prevents excessive temperature buildup in the cylinder block and head. This component is essential for protecting the service life of piston rings and gaskets during high-load operations.

Compatible vehicles and engines

This part is specifically designed for use in Freightliner vehicles, including the Cascadia, Columbia, Coronado, and Century Class models. It is also fitted to Western Star 4900, 49X, 5700XE, and 57X trucks powered by Detroit Diesel DD15 engines. This component ensures reliable performance in heavy commercial vehicle applications where consistent air pressure is critical.

Installation and maintenance

For workshop technicians performing compressor overhauls, it is recommended to inspect the plate's surface flatness and channel cleanliness during every service interval. Ensuring the plate is free of warping helps prevent air or coolant leaks. Proper installation according to manufacturer torque specifications is vital for maintaining a secure seal between the cylinder block and head.

Troubleshooting and service

Maintaining the cooling integrity of the compressor helps prevent premature failure of other internal components. Consult your authorized distributor for more information.
