ACDelco GM Original Equipment Engine Cooling Fan Clutches control the speed of the radiator fan based on the temperature of the air after it passes through the radiator fins. This original equipment engine cooling fan clutch is a GM-recommended replacement for your vehicle’s original components and has been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
During initial engine start up, the electronic fan clutch may produce a loud fan roar or an audible click for up to 3 minutes - this is normal. The noise will cease shortly after disengagement.
