🔌 Function

Moves cooling air through the radiator while operating as a pusher fan in the original equipment layout.

⚠️ Common Signs of Failure

• Engine overheating at low airflow or stationary operation
• Cracked, bent or loose fan blade
• Fan imbalance or vibration
• Blade contact with the shroud
• Corrosion or cracking at the fan spider

🛠️ Service Notes

• Handle the fan carefully and never fit one that is cracked, chipped or distorted — an out-of-balance fan wrecks the pulley bearing and can break up in service
• Check the hub, pulley and drive belt while the fan is off, and make sure the fan turns true with no wobble once fitted
• Fit the fan the correct way round so it moves air in the original direction, and tighten the fasteners evenly to the figures in the workshop manual for your engine
• Confirm the blade tips clear the shroud, hoses and wiring all the way round before starting the engine
