US Motor Works MCK1049 Engine Water Pump with Fan Clutch

Cooling System Replacement Kit

US Motor Works MCK1049 is a water pump and fan clutch kit for vehicles that rely on coordinated coolant flow and airflow to control engine temperature. It is built for direct replacement service on select Chevrolet Colorado, GMC Canyon, Hummer H3, Hummer H3T, and Isuzu i-350/i-370 applications.

The matched water pump and fan clutch design helps address both sides of the cooling system at the same time, reducing the chance of replacing one worn component while the other remains a problem. US Motor Works MCK1049 is designed and tested to meet or exceed original equipment specifications.

Detailed Description

US Motor Works MCK1049 combines the water pump and fan clutch into one service solution for vehicles where both components work together to manage engine temperature. The water pump circulates coolant through the engine, while the fan clutch controls airflow through the radiator. Replacing both parts at the same time helps restore proper cooling performance on Chevrolet Colorado, GMC Canyon, and related GM truck and SUV applications. This part number, MCK1049, is intended for direct-fit cooling system repair on the listed model years.

What It Helps Address

• Overheating caused by a worn water pump
• Reduced radiator airflow from a failing fan clutch
• Coolant circulation issues in the cooling system
• Noisy or inefficient cooling component operation
• Repeat repairs when only one connected component is replaced

Installation Notes and Tips

Replace the water pump and fan clutch together when servicing the cooling system to avoid mixing a new component with a worn one. Verify year, make, and model before installation, especially on Chevrolet Colorado and GMC Canyon trucks and Hummer/Isuzu applications. Follow factory service procedures for coolant draining, component removal, and refill/bleeding after installation.

Quality Assurance

US Motor Works designs and tests this kit to meet or exceed original equipment specifications. Precision machining and quality components are used to support consistent cooling-system performance and engine longevity.
