The Bosch 001 835 11 64 is a 100% new electric auxiliary water pump engineered to restore and maintain proper coolant circulation in your vehicle's cooling system. As an OEM-quality replacement component, this pump is built to meet or exceed original equipment specifications, ensuring dependable, long-lasting performance.

Replacing a failing auxiliary pump promptly helps prevent overheating and potential secondary engine damage.
