Quick Ship SKU #: CMNS-3959031 Cummins Replacement Engine Oil Cooler 03-07 Dodge Ram 5.9L Cummins

Oil cooler failures in Cummins trucks are few and far between, but that does not me they cannot fail. Typically, when they fail, the coolant passages get plugged due to contamination and they can no longer cool the engine oil efficiently. Overheating of the engine oil can start to break down the oil and cause much larger issues with other engine components. Prevent this issue and replace your engine oil cooler with a genuine Cummins Replacement Engine Oil Cooler. This is a direct replacement oil cooler and installs using the factory hardware.
