Overview – BYPASS WATER CONNECTION PIPE 130394-20
130394-20 belongs to the CUMMINS BYPASS WATER CONNECTION PIPE range and serves Cummins diesel engine cooling system bypass circuits. This article covers its features, fitment, maintenance and price, and we can supply the part on request.
Parts Characteristics
130394-20 is the CUMMINS bypass water connection pipe that carries the coolant bypass flow between the engine water circuits, formed to the original route with the correct flange and spigot ends. The tube is made to the OEM material and bore so the bypass flow is maintained at the factory rate. The ends are finished for the original hose and clamp arrangement, so the pipe installs with the standard cooling hardware.
Applicable Models & Applications
This pipe is used on CUMMINS diesel engines where the original 130394-20 bypass circuit applies, including the cooling layouts with the water pump bypass connection. Confirm the flange spacing and the hose end sizes against the pipe removed from your engine before ordering. We can confirm the correct pipe for your engine model from the cooling circuit arrangement.
Maintenance & Replacement
Inspect the pipe at each cooling system service for cracks around the ends and for corrosion pitting, which lead to coolant loss at operating temperature. When replacing, fit new hoses and clamps at both ends and bleed the cooling system after refilling to remove air locks. Check the clamp torques after the first heat cycle, as the hose settles.
