2500 090 350 Compressor Cooling Plate — Cummins Compatible

What does a compressor cooling plate do?

This compressor cooling plate serves as the critical intermediate component positioned between the cylinder block and the cylinder head within an air brake compressor. Its primary function is to transfer heat generated during the compression process into the cooling circuit, preventing overheating and ensuring stable pneumatic performance. By acting as a structural barrier, it also maintains the necessary separation between air, water, and oil channels.

Vehicle and engine compatibility

This component is compatible with several heavy commercial vehicle models, including Freightliner (FS-65, M2 106, FL60, FL80, MT55, MT45, FL50, M2 112, FL70), Kenworth (T370, T170, T440, T470, T300, T270), and Peterbilt (325, 335, 330, 337, 348) trucks. It is also fitted to various buses and commercial chassis such as Blue Bird, Gillig, International (4400, 4300, 7400), and Ford Trucks models using Cummins ISB or ISC engines. Check the compatibility list for specific fitment.

Installation and maintenance

When performing maintenance or repairs on the air brake system, it is vital to inspect the surface flatness of the plate. Any warping can lead to air or coolant leaks regardless of the gasket quality used. For precise installation, always refer to the vehicle manufacturer's service manual regarding tightening torque specifications and sealing surface tolerances.

Maintenance and system longevity

Maintaining an efficient cooling circuit is essential for the longevity of piston rings and valve assemblies. Using high-strength components helps prevent thermal stress in high-pressure applications common in heavy-duty transit and freight operations.
