FAQ

Q1: Is this water pump a direct replacement for my Cummins NT855 engine?

Yes, this water pump (part number 3801708) is manufactured to OEM specifications for the Cummins NT855 engine. It is designed as a direct bolt-on replacement. However, we strongly recommend verifying the part number on your existing pump and comparing the physical dimensions (including the mounting flange and impeller design) to ensure it is the correct variant for your specific engine serial number. If you have any doubts, please contact us with your engine details for confirmation.

Q2: What is the installation procedure for this water pump?

Installation is a standard mechanical procedure but requires technical expertise. Generally, you will need to drain the coolant, remove the fan belt and fan hub, unbolt the old pump, clean the mounting surface, apply a new gasket (not included), and install the new pump. It is critical to replace the coolant and bleed the cooling system after installation to prevent airlocks. We recommend consulting your engine service manual for the specific torque specifications and tightening sequence for the NT855 engine. Always use new gaskets and O-rings to ensure a proper seal.

Q3: How can I ensure the longevity of this water pump?

To maximize the service life of your new water pump, use the correct type and concentration of coolant as recommended by Cummins. Regularly inspect the cooling system for leaks, check the condition of the fan belt tension, and ensure the radiator is clean and free from obstructions. It is also good practice to replace the thermostat simultaneously to ensure the entire cooling system is operating efficiently. Avoid running the engine with low coolant levels, as this can cause cavitation damage to the pump impeller.
