US Motor Works MCK1007 Engine Water Pump with Fan Clutch

Cooling System Service Kit for GM Trucks and SUVs

US Motor Works MCK1007 is a matched engine water pump with fan clutch kit for vehicles that rely on coordinated coolant flow and airflow to control engine temperature. Replacing both components together helps restore cooling performance and reduces the risk of installing a new part against a worn companion component.

• Matched water pump and fan clutch replacement set
• Designed and tested to meet or exceed original equipment specifications
• Precision-machined components for consistent fit and operation
• Supports proper coolant circulation and fan-driven airflow
• Built for GM truck, SUV, and van applications

US Motor Works Water Pump and Fan Clutch Line

The US Motor Works Water Pump and Fan Clutch kit line is built for direct cooling-system service where both the pump and clutch are part of the same repair. Part number MCK1007 is intended for buyers looking for a coordinated replacement on Chevrolet Silverado 1500, GMC Sierra 1500, Cadillac Escalade, and related applications. This approach helps complete the cooling repair in one service event instead of replacing one worn component and leaving the other in place.

Common Repair Reasons

• Overheating caused by reduced coolant circulation
• Weak fan engagement that limits airflow through the radiator
• Noise or wear from a failing fan clutch
• Coolant leaks or pump wear at the water pump assembly
• Repeat cooling-system repairs when only one component was replaced

Installation Notes and Tips

Replace the water pump and fan clutch together when servicing the cooling system so the new parts work as a matched set. Verify the vehicle’s year, make, model, and listed notes such as With A/C, SS model, or Automatic temperature control before installation. On Chevrolet Silverado 1500 and GMC Sierra 1500 applications, confirm the exact engine and cooling configuration against the vehicle record before ordering.
