Product Details
Description
(*UPGRADED TO 2 ORINGS)
This Water Transfer Tube Set (Cummins part numbers 4367122 and 5575183) is a high-quality replacement for the coolant bypass and water transfer assembly used on Cummins ISX and ISX15 engines. Designed to meet or exceed OEM specifications, these tubes ensure efficient coolant circulation between major engine components, helping maintain proper engine temperature under heavy-duty operating conditions. The Coolant Bypass Tube operates as part of the engine's cooling system, transferring coolant from the water pump to the back of the engine block. This is crucial in marine applications as the EGR systems found in on-road applications are generally absent. This is due to several factors, such as the corrosive environment, limited space in engine rooms, weight restrictions, and consistently high engine loads and speeds.
