Mercedes-Benz G-Class Radiator Fan Replacement Parts

The W463 G-Class ran from 1989 through to 2018, with significant updates along the way including a notable facelift in 2012, and fan assemblies can vary across that long production run depending on the engine fitted. Engine code is the critical detail here — a fan from the same engine code is far more likely to interchange than one from a different engine regardless of year. Confirm with the breaker against your registration before buying, as ancillary and mounting changes across the W463 production span can affect fitment even between seemingly similar years.

The W464 is the current-generation G-Class, launched in 2018 as a significant redesign, and it uses different engine configurations and a substantially revised cooling system compared to the outgoing W463. These two generations are not the same platform, so a W464 fan is very unlikely to fit a W463 without modification. Always confirm with the breaker against your registration, but treat these as separate parts unless the breaker can specifically verify compatibility.

Yes, engine code is the most important fitment factor for a radiator fan on the G-Class, which has been offered with a wide range of petrol and diesel engines over the years including naturally aspirated units, turbodiesels, V8 petrol engines, and AMG variants. A fan sized and rated for a 3.0-litre diesel will not necessarily suit a 4.0-litre twin-turbo AMG V8. Give the breaker your engine code — found on your V5C or via a VIN check — rather than relying on the year alone, as this is the single most reliable way to match the part.

Trim level as such does not affect fan fitment, but the engine fitted under that trim absolutely does — the G350d and G63 AMG have completely different engines and cooling requirements, so the fan assemblies are not interchangeable. The AMG badge tells you there is a different engine underneath, which is what drives the parts difference, not the trim name itself. Always quote your engine code to the breaker rather than just the trim or badge name.

Yes, all Mercedes-Benz G-Class variants — petrol and diesel alike — are fitted with a radiator fan as part of the engine cooling system, so this is a genuine part that exists across the full G-Class range. The G-Class is a four-wheel-drive vehicle throughout its history, and all engine variants require active cooling, meaning no G-Class left the factory without one. The specific fan assembly, however, varies by engine code, so supply your engine code to the breaker for an accurate match.

Both of those years fall within the W463 generation (1989–2018), with the 2012 facelift bringing various updates to the model, so on paper they share a generation — but whether the fan itself interchanges depends heavily on whether both vehicles share the same engine code. If the engine codes match, fitment is more likely, but ancillary and mounting changes within a long production run like the W463 mean you should confirm against your registration with the breaker before purchasing.
