Detailed Description

US Motor Works MCK1003 combines the water pump and fan clutch into one service solution for vehicles where both parts share the same cooling workload. The water pump circulates coolant through the engine, while the fan clutch controls airflow through the radiator. Replacing both components together helps complete the cooling repair on Dodge Ram 1500, Ram 2500, Ram 3500, Ram Van, Ramcharger, B150/B250/B350, B1500, and Jeep Grand Cherokee applications without repeating the job later. The MCK1003 is also listed for 2015 Ram 4000.

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

Common Problems This Part Can Address

• Engine overheating from reduced coolant circulation
• Weak radiator airflow caused by a worn fan clutch
• Coolant leaks or pump wear at the water pump assembly
• Repeated cooling repairs when only one component is replaced
• Temperature instability in high-mileage Dodge and Jeep cooling systems

Installation Notes and Tips

Replace the water pump and fan clutch together when both components show wear, since one failed part can shorten the life of the other. Verify engine cooling package details before ordering, including notes such as without max cooling or without heavy duty cooling where listed. Confirm the vehicle year, make, and model against the fitment data for your specific Dodge or Jeep application. Part number MCK1003 should be matched to the exact cooling configuration before installation.
