This high-quality Electric Auxiliary Water Pump is a direct replacement for Mercedes-Benz OE numbers 2048350264 and 2218350064. Designed for M272 and M273 engine platforms, this pump is essential for circulating coolant through the heater core to provide cabin heat, as well as assisting in cooling the turbocharger or intercooler circuits. Manufactured to strict OEM specifications, it ensures reliable operation, quiet performance, and long service life.
Ensure the engine is cool and the battery is disconnected. Locate the auxiliary water pump (typically near the firewall or heater core). 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.
