Water Pump – 06A 121 012G (Metrix)

Description

Product Description – Water Pump 06A 121 012G

The 06A121012G Water Pump is an OE‑style replacement used on many popular Volkswagen and Audi 4‑cylinder engines. Driven by the timing belt, this pump continuously circulates coolant through the engine and radiator, maintaining proper operating temperature and protecting the engine from overheating.

Over time, the original pump can develop bearing play, noise, or coolant leaks at the shaft or sealing surface. Replacing it with this direct‑fit 06A121012G unit restores reliable coolant flow and helps ensure long‑term engine durability.

• OEM reference: 06A 121 012G
• Includes new O‑ring seal for proper installation
• Cast and machined housing for precise fit and leak‑free sealing
• Correct impeller design for factory‑spec coolant circulation
• High‑quality bearing and mechanical seal for quiet, long service life
• Direct replacement for the original timing‑belt‑driven pump

Applications

Found on numerous VW and Audi 1.8T / 2.0 8V/20V engines (Golf, GTI, Jetta, Passat, New Beetle, A4, TT, etc.) that specify part number 06A121012G.

(Always confirm compatibility via VIN or by matching the part number on your existing pump.)

Service Notes

• This pump is usually replaced during a timing belt service; it is highly recommended to install a new belt, tensioner, and idlers at the same time.
• Use approved G12/G12+/G13 VW/Audi coolant and bleed the system thoroughly after installation.
