Key Features

• Engine Water Pump with Fan Clutch kit from US Motor Works

Detailed Description

The US Motor Works Water Pump and Fan Clutch kit is built for vehicles where the water pump and fan clutch work together to regulate engine temperature. The water pump circulates coolant through the engine, while the fan clutch controls airflow through the radiator. Replacing both components at the same time helps avoid repeat cooling-system service when one worn part damages the other. This kit is a practical OE-style solution for Chevrolet Express 1500, Express 2500, Express 3500, GMC Savana 1500, Savana 2500, Savana 3500, and related GM truck and SUV applications. If you are searching for MCK1055 for a Chevrolet Express or GMC Savana cooling repair, this matched set is built for that service.

This part cross-references Monroe Shocks & Struts (e.g., 172286, 182286) for the same application.

What It Helps Fix

• Engine overheating caused by reduced coolant circulation
• Weak radiator airflow from a worn fan clutch
• Noisy or inefficient cooling-system operation
• Repeat repairs when only one cooling component is replaced
• Cooling performance loss in high-load GM van and truck use

Installation Notes and Tips

Replace the water pump and fan clutch together when both components show wear. Inspect the cooling system, belts, hoses, and related seals before reassembly. Confirm vehicle-specific fitment by year, make, model, and notes, especially for A/C and cutaway chassis applications. For search accuracy, MCK1055 is commonly referenced for Chevrolet Express and GMC Savana cooling repairs.
