Land Rover Part Number: ERR2266 - Viscous Coupling for Cooling Fan
ERR2266 is a viscous coupling for the cooling fan fitted to 300Tdi engines. Fitted within the engine cooling system, it couples the engine-driven cooling fan to the drive assembly and uses a viscous shear medium between internal plates to vary torque transfer: it increases torque to raise fan speed as thermal demand rises and allows controlled slip when cooling demand is lower. The unit interfaces directly with the fan hub and the pump or pulley assembly. For reference, the cooling fan that fits this viscous unit is part number ERR2789.
