Engine Coolant Overflow Reservoir Tank for BMW 540i/740i 2016-2017 3.0L
Main Description
The Engine Coolant Overflow Recovery Reservoir Tank is a direct-fit replacement designed for BMW models equipped with a 3.0L engine, specifically the 2016–2017 BMW 540i and the 2016–2017 BMW 740i. This reservoir captures overflow coolant during engine heat-up and safely returns it to the cooling system as temperatures drop, helping maintain proper coolant level, reduce spillage, and support consistent engine temperature management.
