Used Mercedes-Benz G-Class Washer Pump

The washer pump is a genuine fitment on all generations of the Mercedes-Benz G-Class, which has run continuously from 1979 to the present day, with a major redesign for the current W464 generation launched in 2018. Whether a pump from a pre-2018 W463 car will physically connect and function correctly on a W464 — or vice versa — is something you should confirm with the breaker against your registration, as connector plugs and mounting arrangements can differ across that boundary. Within the long-running W463 generation (roughly 1990–2018), pumps are more likely to be compatible, but always check against your specific year.

Trim level does not affect washer pump fitment on the G-Class — the pump itself is the same functional component whether your car is a standard model, an AMG Line, or a limited edition such as Edition 1. These trim designations reflect interior, cosmetic, and equipment differences rather than any change to the washer system hardware. When contacting a breaker, your registration number and the generation of your G-Class (W463 or W464) are the details that matter most.

Engine type does not affect washer pump fitment on the G-Class — the windscreen washer system is independent of the drivetrain and works the same way whether your vehicle is a diesel (such as the 350d) or a petrol (such as the 500 or 63 AMG). The key fitment factors are the generation and model year, not what is under the bonnet. Supply your registration to the breaker so they can match the correct unit.

Many G-Class models use separate pumps for the front and rear wash systems, so you need to be clear with the breaker about whether you need the NS/OS front pump or the rear pump. Confirm with the breaker which pump position you need and whether your specific model year uses one pump or two, as this can vary. Giving them your registration is the most reliable way to ensure you get the right unit.

Both a 2010 and a 2016 G-Class fall within the long-running W463 generation, which ran from approximately 1990 through to 2018, so there is a reasonable chance the washer pump is compatible across those years. That said, Mercedes did make running changes to the W463 during its very long production life, so connector type and pump specification can differ between years even within the same generation. Ask the breaker to check the part number against your registration before purchasing to be sure.

Findapart connects you with UK-based vehicle dismantlers (breakers) who stock used parts from Mercedes-Benz G-Class vehicles, and you can request quotes from multiple breakers at once. When you make an enquiry, include your registration number and let the breaker know whether you need the front or rear pump, as this helps them pull the correct part quickly. Used washer pumps are generally a cost-effective repair, and a reputable breaker should be able to confirm fitment before you commit.
