Used Mercedes-Benz GLE Water Pump

The GLE W166 ran from 2015 to 2019, so both years sit within the same generation, which is a good starting point for compatibility. However, fitment depends primarily on your engine code rather than the year alone, as Mercedes used several different diesel and petrol engines across that generation, each with its own water pump specification. Check your V5 or run a VIN check to get your engine code, then confirm with the breaker that the donor vehicle shares the same code before buying.

The W166 GLE ran from 2015 to 2019, while the W167 replaced it from 2019 onwards, and these are entirely different generations with different engine families. Crossing that generational boundary makes compatibility very unlikely, even if the fuel type appears to match, because the engine codes changed significantly between generations. Always confirm the engine code from your V5 with the breaker rather than relying on the model name alone.

Trim level has no bearing on water pump fitment whatsoever — AMG Line, Sport, and any other trim designation on the GLE are purely cosmetic and equipment-level distinctions. What determines the correct water pump is your engine code, followed by fuel type and gearbox type, none of which change with trim. Give the breaker your engine code and they will be able to match the right part regardless of what badge is on the car.

The 350d badge points to a diesel engine, which is helpful, but the badge alone is not enough to guarantee fitment because engine codes can vary across model years and production runs even within the same displacement designation. Locate your specific engine code from the V5 or a VIN check, as this is the single most reliable piece of information for matching a water pump. Share that code with the breaker and they can verify whether the donor part is a direct match.

No — petrol and diesel engines are entirely different units with different water pump specifications, so the two are not interchangeable. Even within the diesel range, different displacements and engine codes carry their own pump designs, so fuel type is only the first filter. Always confirm your exact engine code with the breaker to ensure the used part is the correct one for your specific engine.

Beyond the engine code, it is worth telling the breaker your model year and whether your car is an early W166 (2015–2019) or a W167 (2019 onwards), as this helps them narrow down the donor vehicle quickly. Fuel type and gearbox type are also useful, particularly because some engine and ancillary configurations differ between automatic and manual variants. If you are unsure of any details, a VIN check will surface the engine code and full specification, giving the breaker everything they need to confirm fitment.
