Used Mercedes-Benz CLA Water Pump

The Mercedes-Benz CLA (C117) ran from 2013 to 2019, with a facelift arriving in 2016, so a 2015 and a 2013 car are both pre-facelift models — but fitment still turns on the engine code rather than the year alone. If both cars share the same engine code (printed on your V5 or available via a VIN check), the pump is very likely the same unit, but you should confirm with the breaker against your exact registration before buying, as ancillary and mounting details can change quietly within a production run.

The CLA (C117) was facelifted in 2016, and while the engine family carried over, crossing that 2016 facelift boundary is where fitment becomes less certain — even on the same engine code, suppliers occasionally revised ancillary components at a major refresh. Name your engine code and registration to the breaker and let them cross-reference their stock before committing.

Yes, all Mercedes-Benz CLA variants are fitted with a water pump as part of the engine cooling system — whether petrol or diesel, the engine requires coolant to be circulated and the water pump does that job. The exact pump you need depends primarily on your engine code, so check your V5 or run a VIN check to confirm it before sourcing a used part from a breaker.

Yes, fuel type matters significantly — a petrol CLA (for example running a 1.6 or 2.0 turbo petrol engine) and a diesel CLA (such as the 2.2 CDI) use completely different water pumps that are not interchangeable. Always quote your engine code to the breaker, as that single detail identifies the correct pump far more reliably than quoting fuel type or badge alone.

Trim level makes no difference to water pump fitment on the CLA — the pump is driven by the engine, and AMG Line, Sport, and SE trims all share the same engine units when the engine code matches. What matters is the engine code on your V5; give that to the breaker and they can match the correct pump regardless of trim.

In most cases the water pump itself is the same whether your CLA has a manual or 7G-DCT automatic gearbox, because the pump is an engine-driven component rather than a transmission component. That said, always quote both your engine code and gearbox type to the breaker when asking for a quote, as they may need to confirm there are no ancillary bracket differences on their specific unit before it leaves the yard.
