CAT C15 Oil Cooler Gasket Kit

A CAT C15 Oil Cooler Gasket Kit typically includes all necessary gaskets and seals required to properly reseal the oil cooler assembly to the engine block. This covers the oil cooler core gaskets, inlet and outlet sealing rings, and any o-rings specific to the C15 engine's oil cooler mounting configuration, ensuring a complete and leak-free installation.

Radiator Supply House supplies OEM-equivalent aftermarket gasket kits through its ICEBOX Replacement Parts line. These parts are engineered to match OEM specifications for dimensions, material composition, and sealing performance, providing a cost-effective alternative to dealer-sourced OEM parts without compromising reliability or fit for CAT C15 engines.

The CAT C15 engine was produced across multiple equipment platforms and year ranges, so compatibility can vary. It is important to verify your engine's serial number and arrangement number before ordering. Radiator Supply House specialists can help confirm the correct gasket kit for your specific C15 variant, whether it is used in construction equipment, trucks, or generator sets.

The CAT C15 engine is used in a wide range of heavy-duty applications including on-highway Class 8 trucks, large construction equipment, mining machinery, marine vessels, and industrial generator sets. Common platforms include Caterpillar track-type tractors, motor graders, heavy haul trucks, road-building equipment, and asphalt compaction machinery.

Installation requires draining coolant and engine oil, removing the oil cooler assembly, thoroughly cleaning mating surfaces, and reassembling with proper torque specifications. While experienced diesel mechanics can perform this repair, it is a moderately complex procedure. Always consult the CAT C15 service manual and follow all recommended torque sequences and surface preparation steps.
