Upgrade your engine bay by replacing the ugly OEM plastic coolant overflow tank with the precision-crafted, CNC-machined PERRIN Coolant Overflow Tank!
The PERRIN Coolant Overflow Tank gives you extra clearance for aftermarket intercooler piping and pairs perfectly with performance kits that don’t come with a tank. Its 36-cubic-inch capacity and universal design make it a great fit for most coolant systems that use OEM overflow tanks.
PERRIN Coolant Overflow Tanks feature an integrated lid for a sleek and functional design. Simply lift the cap to quickly check or top off your coolant.
The kit includes detailed instructions, several feet of high-quality silicone hose, and multiple mounting brackets, allowing you to install the tank virtually anywhere on any vehicle.
The PERRIN Coolant Overflow Tank replaces your car’s old coolant tank with a stronger, better-looking one that fits easily with performance parts. It’s made from sturdy metal, comes in bright colors, and is simple to check or fill.
