Frequently asked questions

What does the ERR4996 viscous unit do?
The ERR4996 is a viscous fan coupling for the V8 EFI engine. It drives the cooling fan and automatically varies fan speed with engine temperature, pulling more air through the radiator when the engine runs hot and freewheeling when cool.
Which vehicles does the ERR4996 viscous unit fit?
It's designed for the V8 EFI engine as fitted to the Discovery 1, Discovery 2, and Range Rover P38. Confirm your vehicle has the EFI V8 rather than the carburettor version before ordering.
What are signs the viscous unit is failing?
Typical symptoms include a loud, constant fan noise even when the engine is cold, engine overheating under load, or little resistance felt when spinning the fan cold. A worn viscous unit should be replaced rather than left in place.
How many viscous units are needed for a cooling fan repair?
Just one. The ERR4996 is a single fan coupling unit fitted between the water pump pulley and the fan blade, and only one is used per vehicle.
