Mercedes-Benz G-Class Radiator Replacement Parts

The W463 generation ran from 1989 through to 2018, with a significant facelift and mechanical updates arriving around 2012, so a radiator from before that boundary may not cross over to a post-2012 car without modification. Engine code is the critical detail here — a radiator matched to the same engine code is far more likely to be compatible than one matched purely by year. Confirm with the breaker against your registration whether a specific unit will cross that 2012 boundary before buying.

Both years fall within the W463 generation (1989–2018), but engine code and gearbox type are the fitment details that matter most — a radiator from a 2015 and a 2018 car sharing the same engine code is a much stronger match than year alone suggests. That said, ancillary bracket and mounting details can change quietly mid-production, so confirm the specific part number with the breaker against both registrations before committing.

The W464 is an entirely new generation introduced for the 2019 model year, with a redesigned platform and updated engine range, so a W463 radiator will not fit a W464 without significant problems. These are different generations and the part is not transferable — make sure you quote the correct generation to the breaker, and supply your engine code from the V5 or a VIN check for the most accurate match.

Trim level and badge name do not determine radiator fitment — what matters is the engine code, fuel type, and whether the car has an automatic or manual gearbox. A G350d carries a diesel engine and a G500 a petrol unit, so these would indeed use different radiators, but that difference is down to the engine, not the trim name. Give the breaker your engine code (found on the V5 or via a VIN check) rather than just the badge, and they can match the correct unit.

AMG models typically run different engine codes from their standard equivalents, and higher-output engines often use uprated cooling, so the radiator from a non-AMG G-Class may not be the right specification even if the cars look identical. The engine code is the single most useful detail you can supply to a breaker — it will tell them far more than the AMG badge alone. Confirm with the breaker against your registration to ensure the unit matches both the engine and any cooling system differences on your specific car.

No — fuel type directly affects the cooling requirements and radiator specification, so a diesel unit and a petrol unit from the same year are unlikely to be interchangeable. Always supply your engine code to the breaker rather than just the fuel type, as this gives them the precise detail needed to locate a correct match. Never assume compatibility based on year and fuel type alone without the breaker confirming against your registration.
