Land Rover Part Number: ERR4996 - Viscous Coupling Unit for Cooling Fan - V8 EFI
ERR4996 is a viscous coupling unit for the engine cooling fan, fitted to the engine cooling systems of 4.0L and 4.6L V8 EFI petrol engines. The unit transmits torque from the engine-driven hub to the cooling fan through a high-viscosity fluid, increasing fan speed progressively as coolant temperature rises and allowing slip at lower temperatures to reduce unnecessary fan drag on the engine. This part is the viscous element only; the plastic cooling fan is a separate item. Use the compatibility data below to confirm fitment against your V.I.N.
Compatibility
- Discovery 2 (1998-2004) - V8 Petrol 4.0L & 4.6L EFI
- Range Rover P38 - V8 Petrol 4.0L & 4.6L EFI
