ACDelco GM Original Equipment Engine Cooling Fan Assemblies consist of an engine cooling fan and related components and are GM-recommended replacements for your vehicle’s original components. The engine cooling fan moves air across the radiator and A/C condenser to remove heat from the engine cooling system and the A/C refrigerant system. The fan may be belt-driven or operated by an electric motor. These original equipment engine cooling fan assemblies have been manufactured to fit your GM vehicle, providing the same performance, durability, and service life you expect from General Motors.
