Product Description

This high-quality Electric Auxiliary Water Pump is a direct replacement for Mercedes-Benz OE numbers A0005002686 and 0392024050. Designed for modern M274 and M264 engine platforms, this pump plays a critical role in the vehicle's 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 helps circulate coolant during cold starts to bring the engine to operating temperature quickly. Manufactured to strict OEM specifications, it guarantees reliability and performance.

Installation Guide

Ensure the engine is cool and the battery is disconnected. Locate the auxiliary water pump (usually mounted on the engine block or firewall). Disconnect the electrical connector and coolant hoses (have a catch pan ready for minor spillage). Remove the old pump and install the new one with new seals/O-rings if provided. Reconnect hoses and electrical plug. Check coolant level and top up if necessary.
