Detailed Description

InMotion WU9104 is an engine water pump intended to restore proper coolant circulation in compatible Nissan trucks and SUVs. The impeller design helps move coolant efficiently through the engine and radiator circuit, while the bearing and seal construction supports stable operation under normal thermal cycling. The housing is made to resist corrosion, which is important in vehicles exposed to age, heat, and coolant contamination. If you are servicing a Nissan Pathfinder, Nissan Pickup, or Nissan D21, WU9104 provides a direct-fit replacement path for cooling system maintenance.

What It Helps Address

• Engine overheating caused by weak coolant circulation
• Coolant leaks from worn pump seals
• Noise from failing pump bearings
• Reduced cooling performance in aging Nissan cooling systems
• Service replacement for a worn WU9104 water pump

Installation Notes and Tips

Before installation, inspect the cooling system for contamination, hose wear, and gasket surface condition. Flush old coolant if needed and verify that mating surfaces are clean and flat. Confirm vehicle fitment by year and model before ordering; this part fits 1987-1995 Nissan Pathfinder, 1995 Nissan Pickup, and 1986-1994 Nissan D21. The part number WU9104 should be matched to the application during service.
