Weapon R 05-07 Scion tC Coolant Overflow Tank

This is the Weapon R coolant overflow tank for your 2005-2009 Scion tC. It's designed to replace the factory plastic tank, which can become brittle and crack over time, leading to coolant leaks. Keeping your cooling system functioning properly is key to preventing overheating and engine damage.

This tank is constructed from aluminum, making it a more durable replacement than the original plastic unit. It's built to fit your tC directly, meaning installation should be straightforward, often bolting into the factory location with minimal fuss. Having a solid, leak-free coolant reservoir helps maintain the correct coolant level in your system, which is crucial for consistent engine temperature regulation.
