US Motor Works MCK1009 Engine Water Pump with Fan Clutch

Water Pump and Fan Clutch Kit for GM Cooling Repair

US Motor Works MCK1009 is a matched engine water pump with fan clutch kit for select Chevrolet, GMC, Cadillac, and Oldsmobile applications from 1987-1995. It is built for direct cooling-system service on vehicles such as the Chevrolet Astro, Chevrolet S10, and GMC Safari, where the water pump and fan clutch work together to manage engine temperature.

Key Features

• Matched water pump and fan clutch replacement for coordinated cooling-system repair
• Designed and tested to meet or exceed original equipment specifications
• Precision-machined components for consistent fit and cooling performance
• Supports engine cooling by circulating coolant and moving air through the radiator
• Fits a wide range of GM trucks, vans, and SUVs from 1987-1995

Product Details

The US Motor Works Water Pump and Fan Clutch kit, part number MCK1009, is intended for vehicles where replacing only one cooling component can leave the other worn part in service. Because the water pump moves coolant and the fan clutch controls airflow, both parts should be serviced together to restore proper cooling balance. This matched set is a practical choice for Chevrolet Astro, GMC Safari, Chevrolet S10, and other listed GM applications when addressing cooling-system wear.

This part cross-references no listed aftermarket part numbers in the provided data.

Common Cooling Issues It Can Address

• Engine overheating caused by reduced coolant circulation
• Fan clutch wear that limits radiator airflow
• Water pump leakage or bearing wear
• Cooling-system noise from a failing pump or clutch
• Repeated cooling repairs when only one component is replaced

Installation Notes and Tips

• Verify stamped numbers and engine-specific notes before ordering, especially on applications marked for A/C belt or heavy-duty cooling.
• Inspect belts, hoses, thermostat, and coolant condition during service.
• Drain and refill the cooling system with the correct coolant mixture after installation.
• Confirm fan clutch and water pump alignment before returning the vehicle to service.

Quality Assurance

US Motor Works designs and tests this kit to meet or exceed original equipment specifications, with precision machining used to support proper fit and engine longevity.
