What This Kit Helps Address

• Overheating caused by a worn water pump
• Reduced airflow from a failing fan clutch
• Cooling-system noise from worn rotating components
• Temperature instability during stop-and-go driving
• Repeat repairs when only one cooling component is replaced

Installation Notes

Verify the stamped code on the existing parts before ordering, since fitment depends on engine and cooling-system configuration. Replace the water pump and fan clutch together so the new components work as a matched set. Confirm vehicle year, make, model, and notes such as heavy-duty heater or without A/C before installation.

Quality Assurance

US Motor Works designs and tests this kit to meet or exceed original equipment specifications. The matched water pump and fan clutch construction is intended to deliver consistent cooling performance for the listed Chevrolet, GMC, and Oldsmobile applications.
