US Motor Works MCK1041 Engine Water Pump with Fan Clutch

Water Pump and Fan Clutch Kit

US Motor Works MCK1041 is a matched engine water pump with fan clutch kit for select Chevrolet and GMC trucks and vans. It is built for applications where the cooling system depends on both coolant circulation and airflow control to maintain stable operating temperatures.

This Water Pump and Fan Clutch kit is designed for direct replacement on vehicles such as the Chevrolet Express 1500, GMC Savana 1500, Chevrolet Silverado 1500, and GMC Sierra 1500 in the listed non-air-conditioning applications.

Key Features

• Matched water pump and fan clutch replacement for the cooling system
• Designed and tested to meet or exceed original equipment specifications
• Precision-machined components for consistent fit and operation
• Supports coolant flow and fan-driven airflow in one service job
• Fits select Chevrolet and GMC applications, including Express, Savana, Silverado, and Sierra models

Product Details

The US Motor Works Water Pump and Fan Clutch kit, part number MCK1041, addresses two connected cooling components at the same time. Replacing both parts together helps avoid installing a new water pump against a worn fan clutch, or a new fan clutch against a worn water pump. That makes this kit a practical choice for Chevrolet Express 1500, GMC Savana 1500, Chevrolet Silverado 1500, and GMC Sierra 1500 cooling system service where the listed fitment applies.

US Motor Works MCK1041 is engineered for OE-level specifications and built with precision machining to support reliable engine cooling and long-term vehicle operation.

Common Cooling System Issues

• Engine running hotter than normal
• Reduced airflow from a worn fan clutch
• Coolant circulation problems from a failing water pump
• Noise or vibration from cooling system wear
• Repeat cooling repairs when only one component is replaced

Installation Notes

Replace the water pump and fan clutch together when servicing the cooling system to avoid repeat labor. Confirm vehicle configuration before ordering, since listed fitment includes non-air-conditioning applications for several Chevrolet and GMC models. Verify belt routing, pulley alignment, and cooling system condition during installation.

Quality Assurance

US Motor Works designs and tests this kit to meet or exceed original equipment specifications. The MCK1041 part number identifies the matched cooling system replacement for the listed applications.
