This high-quality Electric Auxiliary Water Pump is a direct replacement for Mercedes-Benz OE number A0005003600. It plays a vital role in the thermal management system of OM642 diesel and M272/M273 gasoline engines. This pump circulates coolant through the turbocharger and heater core even when the engine is off, preventing heat soak and ensuring rapid cabin heating. Manufactured to meet strict OEM specifications, it guarantees a perfect fit, quiet operation, and long-lasting durability.
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.
