This high-quality Electric Additional Water Pump is a direct replacement for BMW OE number 11518616992. Designed for the N13 and N20 engine platforms found in the 1 Series (F20) and 3 Series (F30), this pump plays a vital role in the thermal management system. It ensures that the turbocharger remains cool after the engine is turned off, preventing oil coking and extending turbo life. Additionally, it assists in circulating coolant for the heating system. Manufactured to strict OEM specifications, it guarantees a perfect fit and reliable performance.
Ensure the engine is cool and the battery is disconnected. Locate the additional water pump (usually mounted near the firewall or turbocharger area). Drain a small amount of coolant to prevent spillage. Disconnect the electrical connector and remove the mounting bolts/hoses. Install the new pump, reconnect the electrical plug and hoses, and secure the mounting bolts. Refill coolant if necessary and bleed the system to remove air pockets.
