Cheap Mercedes-Benz SL Radiator Fan

It depends on the generation and engine. Older SL models such as the R107 and R129 used engine-driven viscous-coupled fans alongside electric auxiliary fans, so a mechanical radiator fan does exist on those. From the R230 generation onwards (2001–2012) and the R231 (2012–2022), Mercedes moved increasingly toward fully electric fan assemblies, so what you are looking for on those cars is an electric radiator fan or fan module rather than a belt-driven unit. Confirm which type your car has with your VIN or engine code before ordering, as the arrangement varies by engine.

No — the R230 (2001–2012) and the R231 (2012–2022) are distinct generations with different front-end architecture, cooling pack dimensions and electrical connectors, so the fan assemblies are not interchangeable between them. Even within the R230 generation there was a facelift around 2006 that may have brought ancillary mounting changes, so crossing that boundary should be confirmed with the breaker against your registration. Stick to the same generation and, most importantly, the same engine code as your car.

Engine code matters above everything else for this part. The SL range spans very different engines — from the M272 V6 in the SL350 through to the M156 AMG V8 and M152 in the SL63 AMG — and the fan assemblies are sized and rated to match the cooling demands of each specific engine. A fan from a V6 car is unlikely to be a straightforward fit on a V8 car even if the model year is identical, so always supply the engine code (found on your V5C or via a VIN check) to the breaker.

Yes, because those badges reflect different engines and different cooling requirements, meaning the fan units differ. The SL350 uses a V6, the SL500 and SL55 AMG use V8s, and the SL63 AMG uses a high-output V8 with its own spec, so treat the engine code as the deciding factor rather than the badge alone. Confirm the exact engine code with your breaker so they can match the right unit from a donor car.

Trim level does not affect radiator fan fitment — Sport packs, Grand Edition and similar trim designations are about interior, wheels and cosmetic features rather than the cooling system. What determines the correct fan is the engine code and generation, not what trim the car was specified in. You may find used fans from different trim variants of the same engine are a direct match, but always confirm with the breaker against your registration.

The R230 ran from 2001 to 2012 with a facelift around 2006, and there is a possibility that ancillary or mounting details changed around that point even on the same engine. Whether a pre-facelift fan assembly fits a post-facelift car of the same engine code is something to confirm with the breaker against your registration rather than assume. Providing your full VIN or registration alongside the engine code gives the breaker the best chance of identifying the correct unit for your specific build date.
