Cheap Mercedes-Benz X-Class Oil Cooler

Yes, the X-Class (built 2017–2020) was sold exclusively with turbocharged diesel engines in the UK — the 2.3-litre four-cylinder units shared with Nissan/Renault and the Mercedes-sourced 3.0-litre V6 diesel — and all of these engine variants carry an oil cooler as standard. There was no petrol or naturally aspirated option in the UK, so every X-Class on UK roads will have this part fitted. If you're unsure which engine you have, your V5C or a VIN check will confirm it.

The X-Class had a single generation running from 2017 to 2020 with no significant facelift, so on paper engines carrying the same engine code share the same basic architecture throughout that production run. However, ancillary and mounting details can change mid-production even without a formal facelift, so whether a 2017-sourced cooler bolts straight onto a 2019 car is something you should confirm with the breaker against your exact registration before buying.

Yes — engine code is the single most important detail here, because the 2.3-litre four-cylinder engines (used in the X220d and X250d) and the 3.0-litre V6 (X350d) are entirely different units with different oil coolers that are not interchangeable. Pull your engine code from your V5C or a VIN decoder and give it to the breaker; matching on badge or displacement alone is not reliable enough for this part.

No — the X-Class trim levels (Pure, Progressive, Power, and Streamline in the UK) are cosmetic and equipment grades only and have no bearing on the engine or oil cooler fitted. What matters is the engine code, not the badge on the tailgate, so a Progressive and a Power with the same engine code will use the same oil cooler. Just make sure the donor vehicle the breaker is pulling from shares your engine code.

The X-Class shares its platform and 2.3-litre diesel engine family with the Nissan Navara NP300 and Renault Alaskan, so there is a reasonable chance of parts compatibility on paper. However, Mercedes-Benz did apply their own calibration and ancillary specifications to shared components, so whether the oil cooler itself is a straight swap is not something that can be guaranteed — raise this possibility directly with the breaker and give them your engine code so they can cross-reference before you commit.

For the engine oil cooler itself, gearbox type is not the primary concern — the engine code drives the specification. That said, some X-Class variants with the automatic gearbox also carry a separate transmission oil cooler, which is a distinct part, so make sure you and the breaker are clear on whether you need the engine oil cooler, the transmission oil cooler, or both. Confirm exactly which cooler is needed against your registration to avoid ordering the wrong unit.
