Mercedes-Benz GLC Oil Cooler Replacement Parts

Yes, most GLC variants do have an oil cooler — it is fitted to the petrol and diesel turbocharged engines used across the GLC range, which covers all standard derivatives since the GLC has always used forced-induction engines. The oil cooler is typically an engine oil-to-coolant heat exchanger and is engine-code specific, so the exact unit and its mounting arrangement varies between the different four-cylinder and six-cylinder engines in the range. Always confirm the part against your registration number and engine code with the breaker before purchasing.

The GLC X253 ran from 2015 to 2022, with a significant facelift arriving in 2019, so a 2016 unit and a 2020 unit are from different phases of the same generation. Whether the oil cooler crosses that 2019 facelift boundary depends entirely on the engine code — if both vehicles share the same engine code the cooler itself may be compatible, but ancillary fittings and mounting brackets can change mid-production. Confirm fitment directly with the breaker against both registration numbers and engine codes before buying.

Trim level does not affect oil cooler fitment on the GLC — the oil cooler is determined by the engine code, not whether the car is badged SE, Sport, AMG Line, or AMG Line Premium. A GLC 220d AMG Line and a GLC 220d SE with the same engine code will use the same oil cooler. Do bear in mind that ancillary brackets or hose routing can occasionally differ, so it is worth confirming the full part number with the breaker against your registration.

The GLC 250 and GLC 300 use different petrol engine codes — the 250 used the M274 family while the 300 moved to the M264 family — so the oil coolers are not the same unit and will not interchange. Always go by the engine code stamped on your V5 or obtained via a VIN check rather than the badge on the car, as this is the definitive guide to which oil cooler you need. Provide your engine code to the breaker to ensure you are quoted the correct part.

No — diesel and petrol engines in the GLC use entirely different oil cooler units, and fuel type is one of the key fitment factors for this part. Even within the diesel range the OM651 and OM654 engine families use different coolers, so the engine code is more important than simply knowing whether the car is diesel or petrol. Always supply your exact engine code to the breaker rather than just the fuel type.

The second-generation GLC X254 launched in 2022 and is a newer vehicle, so used parts from breakers will be less plentiful than for the first-generation X253 (2015–2022). The X254 uses updated engine families including revised four-cylinder units, meaning parts are not interchangeable with the X253 even where displacement and fuel type appear similar. Mention to the breaker that you have an X254 and supply your engine code, as breakers handling newer stock will be best placed to source the correct unit.
