Fan Clutch Repair Kit
Cummins®

The Cummins Fan Clutch Repair Kit 3031070 is designed to facilitate the maintenance and repair of fan clutches in heavy-duty trucks. Fan clutches play a role in the engine cooling system by regulating the speed of the cooling fan, which helps maintain optimal engine temperature. This kit is instrumental in ensuring that the fan clutch operates efficiently, thereby contributing to the overall performance and longevity of the vehicle.

Basic Concepts of Fan Clutches

A fan clutch is a component that connects the engine-driven water pump to the cooling fan. It operates by adjusting the fan speed in response to engine temperature and load conditions. This mechanism allows the fan to spin at a variable speed, which enhances engine efficiency and reduces unnecessary strain on the engine. There are two primary types of fan clutches: mechanical and viscous. Mechanical fan clutches use a thermostatic spring to control fan speed, while viscous fan clutches employ a silicone-based fluid that changes viscosity with temperature, allowing for smoother and more precise control of fan speed ¹.
