Product Details

The US Motor Works Water Pump and Fan Clutch kit combines the two cooling components that work together to move coolant and pull air through the radiator. Replacing both parts at the same time helps complete the repair in one service event and supports proper engine temperature control. This kit is compatible with 2001-2006 Chevrolet Silverado 2500 HD, 2001-2006 Chevrolet Silverado 3500, 2001-2006 Chevrolet Suburban 2500, 2002-2006 Chevrolet Avalanche 2500, 2001-2006 GMC Sierra 2500 HD, 2001-2006 GMC Sierra 3500, 2001-2006 GMC Yukon XL 2500, and 2007 Chevrolet Silverado 2500 HD Classic, 2007 Chevrolet Silverado 3500 Classic, 2007 GMC Sierra 2500 HD Classic, and 2007 GMC Sierra 3500 Classic. Part number MCK1045 is a practical choice for GM cooling-system maintenance where both the pump and fan clutch need attention.

Common Problems This Kit Can Address

• Coolant circulation issues from a worn water pump
• Reduced fan engagement from a failing fan clutch
• Engine overheating caused by weakened cooling-system performance
• Noisy or inconsistent fan operation
• Repeat repairs when only one cooling component is replaced

Installation Notes and Tips

Inspect the radiator, hoses, thermostat, belts, and pulley surfaces before installation. Replace the water pump and fan clutch together when both show wear, and verify the application by year, make, and model before ordering. For search reference, this kit is commonly selected for Chevrolet Silverado 2500 HD, Chevrolet Silverado 3500, and GMC Sierra 2500 HD cooling-system service. Part number MCK1045 should be matched to the vehicle’s exact fitment listing before installation.
