Radiator Fan W447 850W for Mercedes-Benz

OE-spec 850-watt radiator cooling fan module for the Mercedes-Benz V-Class W447. Complete unit with motor, impeller and shroud engineered to restore factory 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: Matches OE power rating and ECU speed map 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.

• Balanced, Low-Noise Impeller: Smooth running with reduced vibration and long bearing life.

• Plug-and-Play Fitment: OE connector and mounting points — installs without modification.

• Durable Construction: Heat-resistant 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.

Typical OE reference families (guide only):
A447-906-… / A447-500-… (varies by engine/market/supplier). 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?
No coding for the fan itself; it’s ECU-controlled. 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.
