EVIL ENERGY Universal 800ml Aluminum Coolant Overflow Tank — Radiator Overflow Bottle, Black

EVIL ENERGY Universal 800ml Aluminum Coolant Overflow Tank

Upgrade your vehicle’s cooling system with a purpose-built overflow reservoir designed for a wide range of cars. The tank is crafted from durable aluminum alloy, paired with a flexible NBR hose, delivering a clean, low-profile solution that integrates smoothly with most engine bays. The finish is sleek and matte black, making it a discrete blend with many color schemes.

With a capacity of 800 ml, this overflow bottle provides room for coolant expansion during operation while helping keep the engine bay organized. Its compact length (7.48 inches) and measured diameters (bottom 2.95 inches; cap 1.96 inches) let you plan placement where space is tight, without crowding critical components. The 5/16 inch hose ID is compatible with common radiator hoses, making retrofits or fresh installs straightforward.
