Mini F60 & BMW 1 Series F40 Coolant Expansion Tank (8687503 02)
This part is designed for the MINI Countryman F60 (2017–Present) and BMW 1 Series F40 (2019–Present) models. The item listed was removed from a vehicle within this compatibility range, ensuring genuine OEM quality and factory-standard fit.
The coolant expansion tank (also known as the coolant reservoir) is an important component of the engine cooling system, designed to store excess coolant and regulate pressure within the cooling circuit. It allows the coolant to expand and contract as engine temperature changes, helping maintain proper cooling efficiency and engine temperature stability. A damaged or leaking tank can lead to coolant loss, overheating, or cooling system pressure issues. This genuine replacement unit restores correct coolant storage and cooling system performance.
