EVIL ENERGY Radiator Overflow Tank 800ml Aluminium Silver — Universal, Corrosion-Resistant

EVIL ENERGY's 800ml aluminum coolant overflow tank is a universal replacement radiator overflow bottle engineered to capture excess coolant, vent heat, and resist corrosion in most car engine bays.

This compact, 800ml radiator overflow bottle from EVIL ENERGY is built from lightweight aluminum alloy with an NBR hose and an O-ring sealed cap. It replaces old or cracked plastic reservoirs, helps manage cooling-system fluid that expands under heat, and provides a durable, serviceable mounting option when space allows. The unit is finished in silver for corrosion resistance and a clean under-hood appearance.

How does the EVIL ENERGY overflow tank fit my vehicle?

The tank is designed as a universal replacement and fits most passenger cars and light trucks if there is adequate mounting space. Measurements are specific so you can confirm fit before ordering.

• Overall length: 7.48 inches (190 mm) for compact engine bays
• Bottom diameter: 2.95 inches (75 mm) to fit common mounting clamps
• Cap diameter: 1.96 inches (50 mm) and hose ID: 5/16 inch (8 mm)
• Volume: 800 ml — check your system's reserve requirements

What materials and features improve durability?

EVIL ENERGY uses an aluminum alloy body and a nitrile (NBR) hose to resist corrosion and aging better than many plastic alternatives. The design includes small but purposeful features that improve service life under typical automotive conditions.

• Aluminum alloy construction resists heat and reduces corrosion risk
• NBR fuel hose resists oil and coolant exposure
• O-ring seal on the cap helps prevent leaks during vibration
• 1/16" ventilation hole in the top assists heat dissipation during heavy use

How do I install and maintain this radiator overflow bottle?

The tank is intended for vertical installation with the hose routed away from direct heat sources. Basic tools are needed; the package includes installation instructions and the tank works with common radiator hoses and clamps.

• Install vertically and secure with a compatible clamp or bracket
• Keep the tank clear of exhaust manifolds and other high-heat components
• Inspect O-ring and hose connections periodically for wear or leaks
• Replace hose clamps if corroded; use coolant compatible with your vehicle

Will this affect my cooling system performance?

As a non-pressurized overflow reservoir, the EVIL ENERGY bottle captures coolant displaced by thermal expansion and returns it as the system cools. It does not alter core radiator function, but using an appropriately sized, leak-free tank helps maintain correct coolant levels and reduces fluid loss.

• 800ml capacity handles moderate expansion in most passenger vehicles
• Tight O-ring and hose connection minimize fluid loss from vibration
• Vent hole prevents vacuum lock and supports fluid return
• Aluminum construction helps dissipate small amounts of heat safely

Who is this for: The EVIL ENERGY 800ml coolant overflow tank is ideal for vehicle owners replacing brittle plastic reservoirs, performance or track drivers seeking a durable aluminum option, and DIY mechanics who need a compact, serviceable overflow bottle. Confirm measurements and available under-hood space before purchase to ensure proper fit and routing.
