Fitment Notice
Confirm fitment by engine model, heat exchanger assembly number, and original cap kit part number before ordering. Cummins cooling-system parts can vary by engine family, exchanger style, and production configuration.
When This Part Needs Replacement
Replace this cap kit if the cap is damaged, leaking, corroded, no longer sealing properly, or if the cooling system is not holding pressure as expected. It is also a smart replacement during heat exchanger service when the old cap shows age or wear.
Installation Notes
Inspect the sealing surface before installation. Clean away corrosion or debris, install the correct cap kit, and check for leaks after the engine reaches operating temperature. Do not substitute a cap with an unknown pressure rating.
