Mishimoto's universal 1‑quart aluminum coolant overflow tank replaces fragile plastic reservoirs with a 3mm-thick aluminum body and precision TIG welds. It includes a removable sight tube that can be mounted on either end for flexible installation in tight engine bays and a CNC-machined billet cap with O-ring seal for leak-free operation. Offered in multiple finishes and backed by Mishimoto’s lifetime warranty, it’s a durable upgrade for cooling systems.
