The Genuine Auxiliary Water Pump 059 121 012B is an OEM electric coolant pump built for many Audi and Volkswagen models with larger engines and complex cooling circuits. This pump assists the main water pump by circulating coolant through the turbocharger, heater core, or after-run cooling system. Because of this, the Genuine Auxiliary Water Pump helps control temperatures during and after engine operation effectively.
Genuine Auxiliary Water Pump 059 121 012B — OEM Engineering
This pump is built to original factory specifications for flow rate, noise level, and long-term durability. As a result, it matches the original unit in every critical dimension. Its direct plug-and-play design features OEM connectors and hose fittings, ensuring accurate fit without modifications. In addition, the factory-spec construction ensures proper cooling of the turbocharger and heater circuit, especially at idle or after engine shut-down. Together, these qualities make it a dependable direct replacement for the original unit.
Signs Your Original Electric Coolant Pump Needs Replacing
A failing auxiliary pump shows recognizable symptoms early. Poor cabin heat at idle, reduced turbo cooling, and after-run fan faults are the most common warning signs. Moreover, overheating in heavy traffic is a strong indicator that the pump is no longer circulating coolant correctly. These symptoms left unaddressed can lead to serious heat-related damage to sensitive engine components. When these signs appear, act quickly. Replacing the worn unit restores correct coolant flow before the problem escalates further.
