Rein BMW Expansion Tank With Cap EPK0128

BMW Expansion Tank With Cap

The coolant expansion tank acts as a reservoir for excess coolant as it expands and contracts with temperature changes. Over time, the constant exposure to extreme heat cycles can cause the tank to crack, break, or suffer damage to its nipples or mounting points. To keep coolant properly contained within the system, a damaged tank should be replaced promptly.
