This is a high-quality NPW viscous fan hub, engineered as a direct replacement for the Nissan Patrol Y60 GQ fitted with the RD28T 2.8L turbo diesel engine. This critical cooling component mounts directly to the front of the engine's water pump and controls the engagement of the main cooling fan.
The viscous hub contains a special silicone fluid that expands and locks up as it heats from radiator airflow. This action engages the fan clutch, causing the fan blade to spin faster and pull more air through the radiator to cool the engine. When the engine cools, the fluid contracts, and the fan disengages to reduce engine load and noise.
Failure occurs when this internal fluid leaks out or breaks down over time, preventing the fan from locking up and spinning at the required speed. The most common symptom of a failing viscous hub is engine overheating, especially in slow-moving traffic, while towing, or during low-speed 4x4 work. You may also notice oily fluid streaks on the front of the hub assembly.
For owners who prefer to stick with original equipment, Patrolapart also supplies the Genuine Nissan viscous fan hub for this application. Using Genuine Nissan parts guarantees the precise fit, finish, and performance specified by the factory when your vehicle was new.
