Description

Although it's often overlooked, a durable coolant overflow tank is a crucial component of any cooling system. Leaks within the overflow system can result in air entry into your coolant, which ultimately leads to overheating. Upgrade your plastic overflow tank with Mishimoto's Universal 1 Quart Coolant Overflow Tank. Our tank is constructed from durable 3mm-thick aluminum and features stunning precision TIG welds. In addition, this overflow tank includes a sight tube that provides an accurate view of your fluid level. This sight tube is removable and can be installed on either end of the tank, which is helpful when installing in a cramped engine compartment.--Mishimoto's all-aluminum coolant overflow tank includes a CNC-machined billet cap with an O-ring seal, ensuring leak-free operation. We offer various finishes for this overflow tank, including anodized finishes in black, blue, and red, and a polished aluminum finish. As with all our products, this coolant overflow tank includes our signature Mishimoto Lifetime Warranty.
