Rein BMW Expansion Tank With Cap - 17138570079 EPK0146

BMW Expansion Tank With Cap - 17138570079

The coolant expansion tank serves as a reservoir for excess coolant as it expands and contracts with changing temperatures. Since it’s constantly exposed to extreme heat cycles, it can eventually crack, split, or suffer broken nipples or mounting points. To keep your cooling system sealed and operating properly, any damaged tank should be replaced.
