EVIL ENERGY aluminium coolant overflow tank 800ml — black, universal fit, corrosion-resistant

EVIL ENERGY's 800ml aluminum coolant overflow tank is a compact, universal replacement reservoir designed to collect excess radiator fluid and resist corrosion in high-temperature engine bays. This lightweight, black-anodized reservoir offers a durable alternative to plastic overflow bottles. Built from aluminum alloy with an NBR hose and an O-ring seal, it handles thermal cycling while keeping expansion fluid contained. The top-mounted 1/16" ventilation hole reduces trapped heat, and its 800ml capacity fits most cars where space allows. Installation is vertical and straightforward, and the included instructions help ensure secure routing and connection.

How does this overflow tank fit most vehicles?

The EVIL ENERGY reservoir is designed with common dimensions and hose size to accommodate many engine layouts. Before buying, check that you have the clearance and a 5/16" hose connection point. The tank's compact footprint makes it suitable for tight bays where larger reservoirs won't fit.

• Length 7.48 inches and bottom diameter 2.95 inches for compact installations.
• Cap diameter 1.96 inches for easy filling and inspection.
• Hose inner diameter 5/16 inch fits standard overflow lines.
• Vertical mounting required—confirm a vertical mounting location.

Will the aluminum design withstand engine heat and corrosive coolant?

Aluminum alloy provides good thermal tolerance and resists long-term degradation compared with some plastics. The included O-ring seal helps prevent leaks where the cap meets the bottle, while the NBR hose is selected for coolant compatibility. The small ventilation hole reduces heat buildup without exposing the system to contaminants.

• Aluminum alloy body resists warping and high temperatures.
• NBR hose compatible with most engine coolants and resistant to fuels and oils.
• O-ring seal minimizes seepage at the cap interface.
• 1/16" vent hole aids heat dissipation while maintaining a closed reservoir.

How simple is installation and maintenance?

Installation is intended to be quick for a mechanically inclined person: mount the tank vertically, connect the 5/16" hose, and secure it away from direct heat sources. The package includes installation instructions to guide hose routing and bracket placement. Routine checks are limited to fluid level and occasional hose inspection for secure fittings.

• Comes with installation instructions and requires vertical mounting.
• Connects to standard 5/16" overflow line—no special adapters normally needed.
• Keep clear of manifolds and turbochargers; choose a cool mounting point.
• Periodic inspection recommended: check level, hose condition, and O-ring seal.

What are the exact measurements and capacity?

This reservoir holds 800ml of coolant and is sized to fit many aftermarket and replacement applications. Its compact dimensions make it a good fit for smaller engine bays or where space is restricted. Check vehicle clearances before purchasing to ensure a proper fit.

• Volume: 800 milliliters.
• Length: 7.48 inches; Bottom diameter: 2.95 inches.
• Cap diameter: 1.96 inches for filling and inspection.
• Hose inner diameter: 5/16 inches; ventilation hole: 1/16 inches.

Who is this for? This EVIL ENERGY aluminum coolant overflow tank is aimed at car owners, hobbyists, and professional mechanics looking for a compact, durable replacement reservoir. It suits drivers who prefer metal components over plastic for heat resistance and longevity, and those modifying or upgrading cooling systems where space and reliability matter. Ensure compatibility with your vehicle's mounting space and 5/16" hose fittings before purchase.
