1L Universal Aluminum Coolant Overflow Tank - Radiator Reservoir With Cap

This aluminum coolant overflow tank is a solid upgrade for pretty much any car! Made from 6061-T6 aluminum alloy, it's seriously durable and built to last - this is the same material used in aerospace applications, so you know it can handle engine bay heat and vibration without issues. The 1-liter capacity is perfect for most vehicles, and the universal design means it'll work with Honda, Toyota, Subaru, Mitsubishi, Mazda, Ford, Acura, Nissan, Infiniti, Lexus, Scion, Jeep, Dodge, GM - you name it! The dimensions are 200mm long x 160mm wide x 100mm high with 3mm wall thickness, giving it that sturdy feel. The CNC billet aluminum filler neck is precision-machined and comes with a tightly sealing cap that has an O-ring gasket to prevent any coolant leaks. There's a 12mm OD screw-on hose barb inlet with 9/16-18UNF threading (that's 6AN port for you performance folks), plus bottom and side drain holes for easy maintenance. The fully polished mirror finish looks absolutely professional - nice welds, clean threads, and that quality appearance that makes your engine bay stand out. It works by capturing excess coolant when your engine heats up and pressure builds, then returning it to the radiator as things cool down - simple but crucial for maintaining proper cooling system function. Installation is straightforward, and it's so much easier to maintain than plastic tanks that can crack or discolor over time. Whether you're replacing a damaged overflow tank or upgrading for better performance and appearance, this aluminum tank delivers reliability and that custom look that car enthusiasts appreciate. It's one of those mods that's both practical and visually appealing!
