NISSAN 21060-05D01 Engine Cooling Fan Blade

The genuine OEM Nissan cooling fan blade with part number 21060-05D01 is an essential component of the internal combustion engine cooling system. Specifically engineered for Nissan's TD42 4.2-liter naturally aspirated and turbo diesel powerplants, it works in conjunction with the viscous fan clutch drive to provide forced airflow through the radiator, particularly during low vehicle speeds, heavy load conditions, or at idle.

Technical Specifications and Operation

The cooling fan is designed to maintain continuous and stable heat dissipation from the engine's coolant circuit. The aerodynamic profile of the blades ensures optimal airflow delivery with minimal noise generation and reduced engine load. This genuine part is manufactured from high-grade, heat- and vibration-resistant engineering plastic composite, effectively withstanding aggressive underhood conditions such as thermal cycling, oil vapors, dust, and mechanical vibrations.

• Part Number (OEM): 21060-05D01
• Manufacturer: NISSAN
• Part Type: Cooling fan blade (FAN-COOLING)
• Installation Position: Engine compartment, behind the radiator, mounted to the viscous clutch
• Engine Compatibility: TD42 (4.2 D)
• Material: Heat-resistant engineering composite plastic

Vehicle Compatibility

This part ensures an accurate factory fit for the following models:

• Nissan Patrol (Y61) 4.2 D [1998 – 2016] (FAN-COOLING (TD42))
• Nissan Safari Pick Up (TY61) 4.2 D [1999 – 2012] (FAN-COOLING (TD42))

Symptoms of Wear and Failure

The immediate operating environment of the fan blade is subjected to elevated temperatures and mechanical stress. Material aging, fatigue, or external impacts can result in micro-cracks, warpage, or blade breakage. An unbalanced fan assembly exerts increased bearing strain on the water pump and viscous clutch, causing vibration, whereas damaged or deformed blades with insufficient airflow capacity can lead to engine overheating in heavy terrain or slow traffic conditions.
