Mercedes-Benz GLA Radiator Replacement Parts

The GLA has run across two main generations: the first-generation X156 ran from 2013 to 2019, with a facelift arriving in 2017, and the second-generation H247 launched in 2020 onwards. Radiators within each generation tend to follow engine codes rather than model year alone, so the X156 and H247 are treated as distinct families and parts are not interchangeable between them. Always confirm the exact engine code from your V5 or a VIN check before buying.

Both years sit within the first-generation X156 (2013–2019), but 2017 brought a facelift that may have introduced ancillary or mounting changes affecting radiator fitment. If both cars share the same engine code the core unit is likely compatible, but whether any bracket positions or pipework connections changed across that 2017 facelift boundary is something you should confirm with the breaker against your specific registration. Never assume fitment solely on year.

Yes, engine code is the most important factor for radiator fitment on the GLA — a diesel engine such as the OM651 family will have different cooling requirements and connections compared with a petrol unit like the M270 or M133, so radiators are not shared across fuel types. When contacting a breaker, lead with your engine code (found on your V5 or via a VIN check) rather than just quoting the badge like 200d or 250, as the code removes ambiguity. Gearbox type can also matter where transmission cooling lines run through or alongside the radiator, so mention whether yours is manual or automatic.

Trim level — whether that is Sport, AMG Line, Urban, or Executive — does not affect radiator fitment; it is a cosmetic and equipment distinction, not a mechanical one. What drives compatibility is the engine code, fuel type, and generation, so a radiator from an AMG Line car with the same engine code as your Sport will be the same unit. You may notice cosmetic differences on a used part such as paint marks or bracket colours, but these do not affect function.

The GLA X156 shares platform and engine family with the W176 A-Class and C117 CLA of the same era, and in some cases cooling components do cross over where the engine codes match. However, bodywork packaging differences mean mounting points and hose routing can vary between models, so you should not assume a direct swap even with a matching engine code. Put the question to the breaker with both registrations and let them verify against their parts.

Used GLA radiators appear reasonably regularly through UK dismantlers given the model's popularity, but having the right details ready will save time and avoid a costly mistake. The single most useful thing you can give a breaker is your engine code from the V5, alongside the model year, generation (X156 or H247), and whether your car has an automatic or manual gearbox. With those details a breaker can match the part accurately rather than relying on year and badge alone.
