# 20405919 Fan | Genuine Volvo Penta Part

## 🔧 Product Description

Genuine Volvo Penta pusher-type cooling fan for normal-climate TD520GE radiator installations. The fan uses a steel spider with aluminium blades and is distinct from the hot-climate fan versions.

## 🚤 Compatibility

Typically suits:

-   Volvo Penta TD520GE

-   **Engine Family:** TD

## ⚙️ Key Features

-   Pusher-type engine cooling fan
-   Steel spider with aluminium fan blades
-   Normal-climate specification for TD520GE
-   Used with fan adapter 20506118 where specified
-   Hot-climate alternatives are separate and not interchangeable without checking the complete cooling package
-   Engine type: Volvo Penta 5-litre industrial diesel

## 🔌 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
