BMW F30 F31 LCI 2.0 Petrol Hybrid Expansion Bottle Tank Reservoir 2016 (8617048)
This part is designed for the BMW 3 Series F30 / F31 LCI (2015–2019) equipped with the 2.0 Petrol Hybrid powertrain.
The item listed was removed from a BMW within this compatibility range, ensuring genuine OEM quality and factory-standard fit.
The coolant expansion bottle (reservoir tank) is a key component of the engine cooling system, designed to store excess coolant and regulate pressure within the cooling circuit. It allows coolant to expand and contract safely as the engine heats and cools, helping maintain the correct coolant level and preventing overheating or pressure build-up. A damaged or leaking tank can cause coolant loss, overheating, or cooling system warnings. This genuine BMW replacement restores proper coolant storage and cooling system operation.
