This used OEM Audi Auxiliary Coolant / Water Pump Bracket (8W0121305AD, also replaces 8W0121305G) secures the secondary coolant or water pump in place on 3.0L V6 engines—both the supercharged and turbocharged versions—found in the S4, S5, and S5 Sportback. Also referred to as the auxiliary water pump bracket, it keeps the pump properly aligned and reduces vibration, preventing coolant leaks or pump damage over time.
