Upgrade the engine bay of your Nissan 350Z with the Weapon-R Coolant Overflow Tank—a high-quality replacement designed to deliver both durability and a show-ready finish. This upgrade replaces the factory plastic tank with a precision-built aluminum unit that enhances both appearance and long-term reliability.
Constructed from 6061 billet aluminum, this overflow tank is TIG welded and features CNC machined fittings for a precise, leak-free design. The polished mirror finish adds a premium look, making it a standout addition for street builds and show cars alike.
The factory overflow tank is often overlooked, but upgrading to a billet aluminum unit not only improves durability over time but also adds a clean, performance-oriented look to your engine bay.
I love the weapon R coolant overflow tank. It’s a huge upgrade to the 350z’s stock plastic overflow. The aluminum tank is very high quality and it fits perfectly. I have one on both my 350z’s
