21991362 Fan | Genuine Volvo Penta Part

🔧 Product Description

Balanced engine-cooling fan manufactured to the blade count, diameter, pitch and rotation direction specified for the Volvo Penta installation that lists 21991362.

⚙️ Key Features

• Engine-specific blade count, diameter and pitch
• Balanced for continuous operating speed
• Designed for the matching hub, shroud and rotation direction
• Provides cooling airflow at the specified engine rating
• Fan-to-shroud clearance must be checked

🔌 Function

Draws cooling air through the radiator or heat-exchange package to control engine coolant and charge-air temperatures.

⚠️ Common Signs of Failure

• Cracked, chipped or distorted blades
• Vibration from imbalance
• Contact with the shroud
• Reduced cooling airflow and overheating
• Loose hub or mounting fasteners

🛠️ 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
