Cummins 2892304 Oil Cooler Assembly

The Cummins 2892304 oil cooler assembly is a plate-type heat exchanger designed for EPA13 15-liter ISX, QSX, and X15 engine platforms. It utilizes stainless steel plate construction with vacuum brazing technology, replacing earlier aluminum core designs to eliminate corrosion and internal leakage failure modes. The unit features a 10-plate configuration optimizing heat transfer surface area for high-horsepower heavy-duty applications. This assembly regulates engine lubricating oil temperature by transferring thermal energy to the engine coolant circuit, maintaining oil viscosity within specified operating ranges for bearing and piston cooling. It is a critical component for engine longevity, particularly in high-load vocational and long-haul duty cycles. The cooler core is supplied as a standalone element; installation requires the separate 4089583 cooler cover kit including gaskets and O-rings for sealing to the engine block. OEM cross-reference interchange includes Cummins part numbers 4965870, 4059460, 4059252, and 3680595. Aftermarket interchange references include PAI Industries 141400, World American WA902-05-2506, and Akmi AK-2892304. Compatible with Freightliner Cascadia, Columbia, International ProStar, Kenworth T680/T800, Peterbilt 579/389, Volvo VNL, Mack Anthem, and Western Star 4900/5700 series trucks equipped with Cummins ISX15 powerplants, as well as construction and industrial equipment utilizing QSX15 engines.
