Rein Expansion Tank With Cap EPK0138

Expansion Tank With Cap

The coolant expansion tank allows excess coolant to flow in and out as temperatures rise and fall. Over time, repeated exposure to extreme temperature changes can cause the tank to crack, split, or break. To keep your cooling system sealed and functioning properly, any tank showing signs of damage—such as cracks, broken nipples, or compromised mounting points—should be replaced.
