Description

High-quality replacement expansion tank to suit a wide range of BMW models, this Mahle unit is a direct replacement for part number 17137642158. Manufactured by Mahle, one of BMW’s trusted OEM suppliers, this coolant reservoir matches the fit and performance of the original.

Over time, BMW’s factory coolant tanks are prone to becoming brittle and cracking due to heat and pressure. This Mahle-made unit is built to OEM specifications with durable, reinforced plastic to provide long-term reliability and a precise fit.

Whether you’re tackling a cooling system overhaul or simply replacing a leaking tank, this part ensures your BMW maintains proper coolant pressure and avoids overheating or premature engine wear.
