Used BMW M3 Radiator Fan

It depends on the generation: earlier M3s (E30, E36, E46) used a mechanical viscous-coupled fan mounted on the engine, so yes, a physical radiator fan exists on those cars. From the E90/E92/E93 generation onwards, BMW switched to fully electric cooling fans, and the M4 generation (F82/F83) which replaced the M3 coupe continued that approach, so those cars do have an electric radiator fan assembly too. The S65 V8 in the E90 M3 (2007–2013) is notably different from the S58 straight-six in the current G80 M3, so the fan setup and mounting differ significantly between generations. Always confirm the exact fan type against your registration with the breaker before ordering.

The E46 M3 (2000–2006) used the S54 straight-six engine, while the E36 M3 (1993–1999) used the S50 or S52 depending on market, and although both generations use a viscous mechanical fan, the engine block dimensions, water pump flange, and fan-shroud mounting differ between these platforms. The E36-to-E46 boundary is a firm generation change and direct fan interchange across it is unlikely, but confirm the specific part numbers against both engine codes with your breaker before committing. Your engine code, found on your V5 or a VIN check, is the most useful detail to give the breaker.

Engine code matters above everything else for this part — a radiator fan is mechanically matched to the engine's water pump, pulley sizing, and shroud, not simply to the model year or badge. The M3 has used distinctly different engines across its generations: the S14 four-cylinder (E30), S50/S52 straight-six (E36), S54 straight-six (E46), S65 V8 (E90/E92/E93), and S55 straight-six turbo (F80), each of which has a different fan arrangement. Check your engine code on your V5 or via a VIN check and pass it to the breaker — it is far more reliable than the year alone.

No — the E90 M3 uses the S65 4.0-litre V8, which is an entirely different engine from the N46, N52, or N54 units found in standard E90 3 Series models, so the cooling fan assembly is not the same. The fan, shroud, and associated ducting are specific to the S65 engine and its cooling requirements, and parts from a non-M E90 are very unlikely to be compatible. Always quote the S65 engine code to your breaker and confirm the part matches your specific car's registration.

Trim level does not affect radiator fan fitment — the fan is dictated by the engine and its cooling system, not by whether the car is a standard M3, Competition, or CS. In F80-generation terms (2014–2018), the Competition pack was a suspension and software option on the same S55 engine, so the fan assembly is the same. You may find cosmetic or ancillary differences in how parts were packaged, but the core fan unit follows the engine code, not the trim badge — confirm the exact part against your registration with the breaker all the same.

These are completely different generations — the F80 M3 (2014–2018) uses the turbocharged S55 straight-six, while the E92 M3 (2007–2013) uses the naturally aspirated S65 V8, and the engines, cooling systems, and fan assemblies are entirely unrelated to one another. Swapping a fan across this generation boundary is not a straightforward like-for-like replacement and is very unlikely to fit without significant modification. Stick to sourcing a fan matched to the S65 engine code for your E92, and verify fitment with the breaker against your registration.
