FAQ

Q: How do I confirm this water pump fits my specific equipment?
A: Verify your engine model is a Cummins NT855 and check your existing part number against our OEM cross-reference (3801715 or 3051408). If your part number matches or is a known supersession, this pump is compatible. For non-standard applications, consult your equipment’s parts manual or contact our technical support with your engine serial number.

Q: What maintenance is recommended for this water pump?
A: During installation, always replace the coolant and inspect the gasket surface for cleanliness. Check the pump for any unusual noise or leakage after installation. We recommend inspecting the water pump every 500 hours of operation or during scheduled engine maintenance. Ensure the cooling system is properly filled and free of air pockets to prevent cavitation damage.

Q: Is this water pump a direct replacement for the original Cummins part?
A: Yes, this water pump is manufactured to OEM specifications as a direct replacement for Cummins parts 3801715 and 3051408. It uses the same bolt pattern, inlet/outlet sizes, and impeller design. However, we recommend comparing the physical dimensions with your old pump before installation to ensure a perfect fit, especially if your engine has been modified or is a non-standard variant.
