Borg Warner ERR4960 Engine Cooling Fan Blade

The Borg Warner ERR4960 is an OEM-quality engine cooling fan blade designed specifically for Land Rover Discovery Series II and Range Rover P38 models equipped with 4.0L and 4.6L V8 engines. This essential cooling system component draws fresh air through the radiator, transmission cooler, and AC condenser to maintain optimal engine temperatures and prevent overheating.

Key Features:

• Engineered to original equipment manufacturer specifications for precise fitment
• Constructed from durable materials designed to withstand high temperatures and continuous use
• Attaches directly to the water pump or viscous fan clutch assembly
• Provides efficient airflow to promote optimal cooling system performance
• Direct replacement for OEM part number ERR4960

The fan blade is manufactured from high-quality plastic materials with multiple blades and a center hub featuring a metal ring for secure mounting. Over time, plastic fan blades can develop stress cracks due to heat cycles and mechanical fatigue, which can lead to blade failure and potential engine damage. Regular inspection for cracks and replacing the fan blade when servicing the water pump or viscous clutch helps ensure reliable cooling system operation.

This component works in conjunction with the viscous fan clutch (ERR4996) to provide temperature-controlled engine cooling. The fan blade should be checked regularly for cracks, warping, or other damage, particularly when operating in demanding driving conditions.
