EVIL ENERGY Radiator Coolant Overflow Tank 1L Aluminum Universal Recovery Tank, TIG‑Welded

This compact 1-liter aluminum coolant recovery tank offers a corrosion-resistant alternative to plastic reservoirs, with a threaded M14*1.5 fitting and compatibility with 3/8" ID hoses. Built for universal fitment across many vehicles, the tank uses a tight-closing cap, O-ring seals, and supplied barb fittings and drain plug to keep coolant contained and reduce leaks. It’s an uncomplicated replacement or performance-minded upgrade for anyone needing a durable, serviceable overflow tank.

How does this overflow tank manage excess coolant pressure?

The tank works with the radiator pressure cap to capture coolant pushed out when system pressure rises above the cap setting. Excess coolant flows through the overflow line into the EVIL ENERGY reservoir, where it cools and returns to the radiator as pressure normalizes.

• Top port handles overflow return and venting for proper pressure equalization.
• Bottom port acts as the radiator overflow inlet for gravity-assisted flow back.
• Sealed cap and O-rings minimize evaporation and leakage under pressure.

What are the key build and fitment details I should know?

This tank is fabricated from aluminum and fully TIG welded for strength and leak resistance. The male-threaded fitting measures M14*1.5 and accepts 3/8" ID hose, making it compatible with many stock and aftermarket setups—however, measure mounting space before purchasing.

• Storage capacity: 1 liter for compact installations and performance cars.
• Thread size: M14*1.5; hose compatibility: 3/8" ID.
• Comes with barb fittings and a bottom drain plug; O-rings included.

How should I install and maintain the EVIL ENERGY coolant reservoir?

Installation is straightforward: attach supplied barb fittings, use Teflon tape on threaded interfaces, and secure hoses to the correct ports. Routine maintenance involves checking seals, topping fluid level as needed, and inspecting welds and fittings for tightness to prolong service life.

• Use Teflon tape on threads to improve airtightness and prevent leaks.
• Ensure cap and O-rings remain clean and replace if worn.
• Drain via bottom plug for easy coolant changes or winter service.

Who is this product for? EVIL ENERGY's 1L aluminum coolant overflow tank suits DIY mechanics, track-day enthusiasts, and anyone replacing a cracked or aging plastic reservoir. It’s ideal when you need a compact, durable recovery tank with easy service access, especially in tight engine bays or vehicles where heat and longevity are concerns. Measure clearance and hose routing before buying to confirm fit, and pair the tank with compatible hoses and a correctly rated radiator cap for reliable cooling system performance.
