Used BMW M5 Radiator Fan

Most BMW M5 generations use an electric water pump and rely on electric auxiliary fans rather than a traditional engine-driven or viscous radiator fan, so the part you are thinking of may be an electric fan or fan cowl assembly rather than a mechanical fan. Certain older M5 variants, particularly the E28 and E34 generations, did use a mechanical viscous fan, so the answer depends heavily on which generation you own. If you are unsure, confirm with a breaker against your registration so they can identify exactly which cooling fan assembly your car uses.

No — the E39 M5 (1998–2003) used the S62 V8 engine while the E60 M5 (2005–2010) used the S85 V10, and these are completely different engines with different cooling system layouts, making the fan assemblies incompatible. The E39 and E60 are entirely separate generations with no meaningful parts overlap on drivetrain components like this. Always confirm the correct assembly with your breaker against your registration.

Yes — engine code is the most important detail you can supply, because the cooling fan assembly is designed specifically around the engine's layout and cooling demands. The M5 has used several distinct engines across its generations (S38, S62, S85, S63) and none of these share the same fan setup. Locate your engine code from your V5 or a VIN check and give it to the breaker before agreeing any purchase.

The M5 is mechanically distinct from standard 5 Series variants regardless of trim level — it runs a unique engine that standard 530d or 520i fans will not suit. Trim level within the M5 itself does not affect the cooling fan fitment; what matters is the generation and engine code. Give your breaker your engine code and registration and they can confirm the correct unit.

The E60 M5 ran from 2005 to 2010 with a facelift introduced in 2007, and in most cases the core S85 V10 engine and its cooling components carried over across that facelift. However, ancillary and mounting changes can occur mid-production, so you should confirm with the breaker against your specific registration rather than assume the parts are identical.

The E60 M5 and E63 M6 share the same S85 V10 engine, so the cooling fan assemblies are potentially compatible — but body differences between the saloon and coupé can affect how the fan cowl mounts and fits in the engine bay. Confirm this cross-model fitment directly with your breaker against both registrations before purchasing, as mounting details can vary.
