Detailed Description

US5086 is an OE-style engine water pump for vehicles in the Chevrolet Express 2500, Chevrolet Express 3500, GMC Savana 2500, GMC Savana 3500, and related truck and van platforms. It also covers 1999-2004 Hummer H1 and several 1999-2000 Chevrolet and GMC C/K-series and Suburban applications. This part cross-references Airtex AW5086 and Gates 44056 for the same application. The US Motor Works US5086 water pump is intended for cooling system repair where a worn or leaking pump needs replacement.

Common Repair Symptoms

  • Coolant leakage from the water pump housing
  • Engine overheating or unstable operating temperature
  • Noise from a worn pump bearing or impeller assembly
  • Reduced coolant circulation through the engine
  • Cooling system service during related front-engine repairs

Installation Notes

Verify engine configuration and pulley style before ordering, since some 1999 applications note a press-on or pressed-on pulley. Replace the fan clutch with the water pump as recommended by the manufacturer. Always inspect the cooling system, belts, hoses, and related seals during installation, and follow the vehicle service procedure for coolant refill and bleeding.
