This high-quality Electric Auxiliary Coolant Pump is a direct replacement for BMW OE numbers 64119197085 and 64116951549. Designed specifically for the BMW X5 (E70) and X6 (E71), this pump plays a critical role in the vehicle's thermal management system. It continues to circulate coolant through the turbocharger and engine block after the ignition is turned off, preventing oil coking and heat damage to the turbo. Manufactured to 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 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.
