Fitment questions

What years does the Mercedes-Benz GLB generation cover, and does the radiator change across those years?

The GLB (X247) launched in 2019 and is the only generation to date, with a facelift arriving in 2023. Within the same generation, radiators often share the same core unit, but minor ancillary and mounting changes can occur mid-production, so always confirm against your exact registration with the breaker rather than assuming a pre-facelift 2019–2022 unit drops straight into a post-facelift 2023-on car without modification.

Will a radiator from a 2020 GLB fit my 2023 facelifted GLB?

The 2023 model year marks the GLB facelift, which can bring cooling system revisions alongside the styling updates, so crossing that boundary is a genuine risk. Your engine code — found on your V5 or through a VIN check — is the most reliable guide, but whether a pre-facelift radiator physically interchanges with a post-facelift shell should be confirmed with the breaker against your registration before you buy.

Does the engine code matter more than the year when buying a used GLB radiator?

Yes — the radiator is a mechanical part that follows the engine, not the badge, so the engine code is the single most useful detail you can supply. A GLB 200 petrol and a GLB 220 d diesel of the same year take different radiators, so always quote your engine code (printed on your V5 or available via a VIN check) when getting a quote from a breaker.

Does it matter whether my GLB has a petrol or diesel engine when buying a radiator?

It matters a great deal — fuel type directly affects cooling requirements and radiator specification, so a diesel unit and a petrol unit are not interchangeable. Quote your engine code alongside your fuel type when contacting a breaker, as this is what they will use to locate the correct part.

Does the trim level affect which radiator fits my GLB — for example, does an AMG Line need a different radiator than a Sport or Progressive?

Trim levels such as Sport, Progressive, and AMG Line are primarily cosmetic and equipment-based distinctions and do not change the radiator specification. What drives fitment is your engine code, fuel type, and gearbox type, so a radiator from an AMG Line GLB with the same engine code as your car is no more or less suitable than one from a Progressive — though you should still confirm the match with the breaker against your registration.

Does the gearbox type affect which radiator I need for my Mercedes-Benz GLB?

Some GLB radiators are combined with an integral transmission oil cooler on automatic-gearbox variants, so an automatic and a manual version of the same engine may not share the same radiator. Always tell the breaker whether your car has the 8G-DCT automatic or a manual gearbox, alongside the engine code, to make sure the part they supply matches your setup.
