850-watt radiator cooling fan module for the Mercedes-Benz V-Class W447. Complete unit with motor, impeller and shroud Designed to restore airflow across the radiator and A/C condenser. Ideal replacement for vehicles requiring high-output cooling (hot climates, heavy loads, long idling).
What’s included / not included:
1× complete cooling fan assembly
Key features:
High-Output 850 W Motor: Designed for maximum heat rejection at idle and in traffic.
Optimised Shroud Geometry: Directs airflow evenly through the radiator/condenser stack for strong A/C performance.
Fitment: Designed to use the existing connector and mounting points.
Construction: composite shroud and sealed motor bearings.
Compatibility:
V-Class (W447) — 2014–Present (incl. 2019–2023 facelift and later updates)
Petrol & diesel variants that specify the 850 W Fan from factory.
Some W447 Vito/Tourer models share this fan family; always confirm by VIN And OE number. Not for earlier W639.
Order by the exact OE number Printed on your existing unit.
When to replace:
Overheating at idle or with A/C on
Fan fails to start, runs intermittently, or stays at full speed
Grinding/roaring noises, wobble, or cracked blades
Cooling-fan circuit fault codes present
Installation notes (pro tips):
Disconnect the battery before removal.
Lift the shroud straight up to avoid bending radiator fins; transfer any rubber grommets/air seals.
Inspect the electrical connector for heat damage/corrosion.
After installation, warm engine to operating temperature and verify fan staging and A/C engagement.
Q&A
Q1: How do I confirm 850 W is correct?
Check the wattage label on your old fan and verify via VIN. Some engines use 600 W Or other outputs.
Q2: Is coding required?
Coding requirements depend on the vehicle and variant; confirm with your installer. If your variant uses a separate PWM/controller, ensure it’s healthy.
Q3: Will this fit all V-Class body lengths (Compact/Long/Extra-Long)?
Yes — body length doesn’t change the fan; match by OE number and wattage.
Q4: Is the controller included?
If your vehicle uses a separate controller, it’s not included; many W447 fans integrate electronics — reuse yours if applicable.
Condition: New aftermarket replacement part. Not an original Mercedes-Benz part; brand and model names are used only to show fitment.
