Cheap Mercedes-Benz S-Class Oil Cooler

These are from different generations — the W221 (2005–2013) and the W222 (2013–2020) — and the oil coolers are not interchangeable between them. Even within a generation, fitment is driven primarily by engine code, so a direct swap depends on both cars sharing the same engine code rather than just a similar year. Check your V5 or run a VIN check to get your engine code, then confirm with the breaker that it matches the donor vehicle.

The S350 and S500 use different engine families — the M272 V6 and M273 V8 respectively — so their oil coolers are not interchangeable even though both sit within the same W221 generation (2005–2013). Engine code is the deciding factor here, not the badge or displacement figure on the bootlid. Always quote your engine code to the breaker rather than just the model name.

Yes, fuel type and engine code both matter — diesel S-Class variants such as the S320 CDI and S350 CDI use different engine families from their petrol equivalents, and the oil cooler design follows the engine, not the badge. All mainstream S-Class variants across the W220, W221, and W222 generations are fitted with an oil cooler as standard, given the thermal demands of their engines. Always confirm your exact engine code with the breaker to ensure the part matches your vehicle.

No — trim level has no bearing on oil cooler fitment for the S-Class; S-Line, AMG Line, and standard SE or Executive specifications all use the same engine-driven components. What matters is your engine code, fuel type, and where applicable your gearbox type, none of which change with trim. You can safely ignore trim designations when searching, but do confirm the engine code with the breaker.

The W222 S-Class ran from 2013 to 2020 with a facelift introduced in 2017, and there were some engineering changes across that production run. Whether an oil cooler from a pre-facelift 2013–2017 car fits a post-facelift 2017–2020 car depends on the specific engine code involved, and there may be ancillary or mounting differences mid-production that are not always well documented. Name the boundary — 2017 facelift — to the breaker and ask them to confirm compatibility against your exact registration before purchasing.

The W220 (1998–2005) and W221 (2005–2013) are separate generations and even where engine families appear similar, detail differences in the oil cooler design, mounting, and ancillary connections mean cross-generation fitment cannot be assumed. Engine code similarity is a useful starting point but not a guarantee of interchangeability across a generational boundary. Provide both registration numbers to the breaker and ask them to verify the part numbers before you commit to buying.
