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

Versatile, durable coolant overflow solution

The EVIL ENERGY coolant overflow tank is designed to support a wide range of vehicles with its 800ml capacity and universal mounting concept. Crafted from aluminum alloy, it combines a rugged, industrial aesthetic with lightweight strength, making it suitable for daily drivers and enthusiast builds alike.

Key features that matter

• Universal fit for most cars: designed to install in common engine bays with ample space.
• Capacity: 800ml, with a 5/16 inch hose ID for flexible routing.
• Aluminum alloy body for durable, corrosion-resistant performance while keeping weight down.
• Ventilation hole on the top (1/16 inch) for heat dissipation and pressure relief.
• O-ring seal to help prevent coolant leakage at joints and connections.
• Includes rubber hose and installation instructions; installs vertically away from heat sources.

In practice, the tank sits neatly in the coolant system, offering a compact reservoir that keeps expansion coolant safely contained. The aluminum surface resists corrosion and provides a clean, industrial aesthetic that can complement many engine bays.

Real-world use cases

• Daily commuting with a need for reliable overflow management during temperature surges.
• Custom or performance builds requiring an unobtrusive, scalable overflow solution.
• Retrofits where space is available behind the radiator or near the engine block.

Considerations for installation ensure you check the available space, confirm the hose size matches your vehicle, and mount the unit vertically away from heat sources. Following the included instructions helps ensure a secure, leak-free setup.

What you gain

• Peace of mind from a dedicated reserve for coolant overflow and expansion scenarios.
• A robust, corrosion-resistant component that blends form and function.
• Easy maintenance with accessible components like the O-ring seal and hose.

Note that while this coolant overflow tank is designed for broad compatibility, always verify fitment in your specific vehicle year, make, and model. The information provided outlines capabilities rather than guarantees, emphasizing potential benefits you can experience when correctly installed.
