Product Description

This high-quality Electric Auxiliary Water Pump (OE: 702671520) is a critical component for the thermal management system in various Volkswagen, Audi, and Mercedes-Benz vehicles. Unlike the main mechanical water pump, this electric unit continues to circulate coolant after the engine is turned off, preventing heat soak in the turbocharger and ensuring consistent cabin heating. Manufactured to strict OEM standards, it offers reliable performance, quiet operation, and long service life.

Installation Guide

Ensure the engine is cool and the battery is disconnected. Locate the auxiliary water pump (usually near the firewall or turbocharger). Drain the necessary amount of coolant to prevent spillage. Disconnect the electrical connector and remove the old pump. Install the new pump, reconnect the electrical plug, and refill the coolant if necessary. Bleed the cooling system to remove air pockets.
