Cheap Mercedes-Benz SLK Radiator

The SLK ran across three main generations: the R170 (1996–2004), the R171 (2004–2011), and the R172 (2011–2016). Each generation is a distinct platform, so a radiator from one generation will not cross over to another. Within each generation there were facelift updates – for example the R171 received a facelift around 2008 – and while many mechanical parts carry across within the same generation, confirm with the breaker against your registration that the specific radiator you're looking at matches your build date.

Both a 2006 and a 2010 SLK sit within the R171 generation (2004–2011), and the R171 received a facelift around 2008. For a mechanical part like a radiator, the engine code is the most important factor – if both cars share the same engine code, fitment is likely, but mounting bracket positions and ancillary connections can sometimes change at a facelift point. Supply your registration and engine code to the breaker so they can confirm whether the pre- and post-facelift radiator dimensions and fittings are identical for your specific engine.

Yes – the engine code is the single most important detail for radiator fitment on the SLK. The SLK was offered with a range of petrol engines across its generations (including four-cylinder and V6 units) as well as diesel options in later models, and each engine variant can have different cooling requirements, hose connections, and radiator sizing. Find your engine code on your V5 or via a VIN check and pass it to the breaker – this is more reliable than going on year or badge alone.

On models fitted with an automatic gearbox, the radiator often incorporates an integrated transmission oil cooler, meaning it is a physically different part from the radiator on a manual gearbox car. Always tell the breaker whether your car is manual or automatic, as fitting the wrong type could affect both engine cooling and gearbox cooling. This is a straightforward check the breaker can run against your registration.

Trim level and badge name do not affect radiator fitment – what matters is the engine code, not whether the car is badged 200, 250, or 350. Those badges reflect different engines, so it is the underlying engine code that determines compatibility, not the trim designation itself. Give the breaker your engine code and they can cross-reference it against the donor vehicle, regardless of what the badges say on either car.

Year alone is not enough for the SLK because multiple different engines were available in the same model year, and each can require a different radiator. The engine code is stamped on the engine itself and is also listed on your V5 or available through a VIN check, and it is the detail breakers use to confirm a radiator will actually fit. Always get the engine code before committing to a purchase – never rely on year or badge alone.
