Product Description
Cummins 5319448 EGR cooler water inlet tube for compatible ISC and ISL 8.9L diesel engines. Designed to direct engine coolant into the exhaust gas recirculation (EGR) cooler, helping regulate exhaust gas temperatures during engine operation.
This metal coolant tube is identified for select Kenworth T3 chassis configurations equipped with compatible Cummins EGR cooling systems. It is associated with updated vertical-plate EGR cooler arrangements.
Cummins identifies 5319449 as a separate water inlet tube configuration for other chassis installations.
