Why Replace Both Components Together

The water pump moves coolant through the engine, while the fan clutch controls airflow through the radiator. When one component wears out, it can place added stress on the other, so replacing both at the same time helps complete the cooling repair in one service. US Motor Works MCK1038 is intended for drivers servicing Chevrolet C1500, GMC K1500, and other listed GM platforms that require the stamped application codes shown in the fitment data.

Common Cooling Problems This Kit Addresses

• Engine overheating at idle or in stop-and-go traffic
• Coolant circulation issues from a worn water pump
• Reduced radiator airflow from a weak fan clutch
• Noise or vibration from failing cooling components
• Repeat cooling-system repairs caused by replacing only one worn part

Installation Notes and Fitment Tips

Verify the stamped code on the existing component before ordering. Fitment notes include codes such as GK, GR, SH, GE, HK, SG, QD, OF, HE, SS, NP, BT, GM, and HL depending on the vehicle. This part fits 1993-1995 Chevrolet C1500, 1993-1995 GMC K1500, and other listed Chevrolet and GMC applications; some 1987-1989 and 1990-1994 van applications also require belt or drive-ratio verification. Confirm engine configuration and accessory drive details against the vehicle before installation.
