Weapon R 12 Fiat 500 1.4L 4cyl Polished Alum Coolant Tank (w/ Pressure Cap)

The Weapon R 826-139-101 is a polished aluminum coolant overflow tank designed for the 2012 Fiat 500 1.4L 4-cylinder.

Constructed from Billet 6061 Aluminum and TIG welded with billet aluminum machined fittings, this tank offers a durable, corrosion-resistant alternative to the stock plastic reservoir. It includes a pressure cap sized for the application and comes with an aluminum bracket, stainless steel clamps, and 3 feet of clear fiber-reinforced tubing for routing coolant or oil vapors.

This tank is a direct replacement for the OEM part and requires no modifications for installation. It aims to provide a cleaner, more finished look under the hood while preventing overflowing fluids from being released onto the ground.
