EVIL ENERGY 1L Aluminum Coolant Overflow Tank – Universal Black Reservoir

EVIL ENERGY 1L Coolant Overflow Tank

Upgrade your cooling system with this compact, 1-liter aluminum reservoir from EVIL ENERGY. The black finish adds a clean, stealthy look under the hood while offering a lightweight, durable solution for managing overflow and maintaining coolant levels during drives and DIY maintenance.

The tank features a male barb fitting with M14x1.5 threading, designed to work with standard 3/8" ID hoses. This makes it compatible with a wide range of vehicles and easy to integrate into existing plumbing. The universal design is intended for most cars, trucks, and SUVs, but it’s wise to measure available space before purchasing to ensure a snug fit.

Practical design for a controlled cooling loop — when radiator pressure rises, coolant is directed through the overflow path into the reservoir, helping to keep the system organized and contained. The bottom port acts as the radiator overflow channel, while the top port handles tank overflow. This arrangement supports a tidy engine bay and reduces the risk of spills during topping off or high-heat driving conditions.

Quality construction and sealed performance

The tank is fully TIG welded and capped with a tight seal to create a closed environment. An O-ring gasket helps prevent leaks at the cap, and a suggestion to use Teflon tape on threaded connections can further improve airtightness and reliability. The combination of aluminum construction and precise welds provides a lightweight, durable reservoir designed to stand up to regular use.
