All items manufactured by US Motor Works are produced to the highest quality technicians and standards and to the latest OE designs. US Motor Works Professional Series Max Cooling Kits are designed to replace the mechanical components of a cooling system. A good replacement water pump should include a new fan clutch as the two shaft are attached to it and work together to move air and coolant. Replacing one without the other can damage the new part and cause repeat work or engine problems. This kit kit will keep your vehicle's engine running continuously in today's demanding environment. All components are new and QA inspected for perfect fit and function. Restore your cooling power by installing a US Motor Works Professional Series Max Cooling Kit.
