Radiator Fan W212 850W for Mercedes-Benz

OE-spec 850-watt radiator cooling fan module for the Mercedes-Benz E-Class W212/S212 (pre-facelift 2009–2012 and facelift 2013–2016). Complete unit with motor, fan blade and shroud engineered to restore factory airflow across the radiator and A/C condenser. Ideal replacement for fans that are weak, excessively noisy, or not engaging.

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 heavy-duty cooling (towing, hot climates, high-output engines).

• Optimised Shroud Geometry: Focuses airflow through the radiator/condenser stack for stable temps and strong A/C at idle.

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

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

• Durable Construction: Heat-resistant composite shroud and sealed motor bearings.

Compatibility:

• E-Class (W212 Sedan / S212 Estate) — 2009–2016 (P/F & F/L)

• Petrol & diesel variants that specify the 850 W fan from factory (often higher-output engines).
  Not for Coupé/Cabriolet (C/A207) or W213 (2016–on). Always confirm by VIN, OE number, and wattage label (850 W) on your original fan.

Typical OE reference families (guide only):
A212-906-… / A212-500-… (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 stuck at full speed

• Grinding/roaring noises, wobble, or cracked blades

• Stored cooling-fan circuit fault codes

Installation notes (pro tips):

• Disconnect the battery before removal.

• Lift the shroud straight up to avoid damaging radiator fins; transfer any rubber grommets/air seals.

• Inspect the electrical connector for heat damage or 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 rating label on your old fan and verify via VIN. Some W212 engines use 600–700 W fans — match what your car has.
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 both pre-facelift and facelift W212?
Yes — as long as the OE number and wattage match your original unit.
Q4: Does this include the controller?
No. Many W212 fans have integrated electronics, but some variants use a separate module — not included.
