Detailed Description

This Metelli water pump is engineered for direct replacement service on many Nissan Altima, Maxima, Murano, Pathfinder, Frontier, Quest, Xterra, NV1500, NV2500, NV3500, and select INFINITI models including G35, G37, FX35, M35, Q50, Q60, Q70, QX50, QX60, QX70, and others listed in the fitment data. The PA1287 uses a metal impeller with six vanes to circulate coolant through the engine and radiator circuit, while the aluminium housing supports durability in demanding cooling-system environments. This part cross-references Gates 43520 and GMB 150-2320 for the same application.

What This Water Pump Helps Address

• Coolant circulation loss caused by a worn or leaking pump
• Overheating from reduced coolant flow
• Noise from a failing pump bearing or impeller assembly
• Coolant seepage at the pump mounting surface or seal area
• Cooling-system service needs on high-mileage Nissan and INFINITI engines

Installation Notes and Tips

Verify engine code, pulley configuration, and model-year fitment before installation. Replace the gasket or seal and O-ring during service, and inspect the belt drive, tensioner, hoses, and coolant condition while the cooling system is open. Confirm the pulley tooth count and mounting alignment match the original part before final assembly.
