Mishimoto 1L Coolant Overflow Tank - Blue

Mishimoto's 1-liter coolant overflow tank is a solid upgrade for any vehicle where the stock plastic tank needs replacing or for custom builds. A cracked or leaking overflow tank can let air into your cooling system, which is a fast track to overheating. This tank is built from tough 3mm-thick aluminum, a big step up from flimsy plastic, and it's put together with precise TIG welds for a strong, leak-free seal.

What's really handy is the integrated sight tube. It gives you a clear view of your coolant level without having to guess, and you can even swap its position on either end of the tank. That flexibility is a lifesaver when you're working in a tight engine bay. The cap is CNC-machined aluminum with an O-ring seal, so you know it's going to seal up tight and prevent any leaks. This blue anodized finish looks sharp, too.
