Radiator Fan W247 400W for Mercedes-Benz

OE-spec 400-watt radiator cooling fan module for the Mercedes-Benz B-Class W247. Complete unit with motor, fan blade and shroud to restore factory airflow across the radiator and A/C condenser. Direct bolt-in replacement for weak, noisy, or non-operational fans.

What’s included / not included:

• 1× complete cooling fan assembly

Key features:

• 400 W OE Output: Matches factory current curve and ECU speed mapping for stable coolant temps and strong A/C at idle.

• Optimised Shroud Geometry: Directs airflow evenly through the radiator/condenser stack.

• Balanced, Low-Noise Impeller: Smooth running with reduced vibration and longer 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:

• B-Class (W247) — 2019–Present

• Petrol & diesel variants that specify the 400 W fan from factory.
  Not for W246 (2012–2018). Always confirm by VIN, OE part number, and the wattage label (400 W) on your original fan.

Typical OE reference families (guide only):
A247-906-… / A247-500-… (varies by engine/market/supplier). Order by the exact OE number on your old unit.

When to replace:

• Overheating at idle or with A/C on

• Fan fails to start, runs intermittently, or stuck at full speed

• Grinding/roaring noise, 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 400 W is correct?
Check the wattage label on your original fan and verify via VIN. Some engines may use higher-output assemblies.
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: Does this fit the B-Class AMG Line?
Yes — body/trim doesn’t change the fan family; match by OE number and wattage.
Q4: Is the controller included?
If your vehicle uses a separate controller, it’s not included; many fans integrate electronics — reuse yours if applicable.
