Product Description

The Cooltec WATER PUMP ELECTRIC 4PIN is designed for efficient engine cooling in select BMW models. This electric water pump ensures optimal coolant circulation, helping to maintain the correct engine temperature during operation. It features a robust cylindrical metal housing, two threaded hose ports for secure fitment, and a 4-pin electrical connector for precise control within the vehicle's cooling system.

This part is compatible with various BMW models, including 1 to 6 Series (135i to 640i), as well as X5 F15 and X6 F16 models with the 35i N55 engine from 2011 onwards. It is essential to confirm your BMW's model, year, engine size, and engine code before ordering to guarantee proper fitment.

Common symptoms of a failing electric water pump include engine overheating, coolant leaks, warning lights on the dashboard, reduced heating performance, irregular temperature gauge readings, and unusual noises from the engine bay. You might also notice poor fuel efficiency or the engine entering limp mode.

If you experience any of these symptoms, replacing the electric water pump is vital to prevent further engine damage. Always ensure the replacement part matches your vehicle's specifications for a reliable repair.
