EVIL ENERGY 2L Aluminum Coolant Overflow Tank – Matte Black, Compact Universal Radiator Recovery with Drain Plug

EVIL ENERGY's 2L aluminum coolant overflow tank is a universal, compact radiator recovery reservoir that manages excess coolant, simplifies monitoring, and helps protect your engine's cooling system.

This lightweight 2-liter aluminum coolant recovery tank fits most vehicles and is finished in matte black for a clean under-hood appearance. It replaces or supplements OEM expansion bottles to capture boiled-over coolant and return fluid to the cooling system as temperatures normalize. Built with 12 mm barb inlet/outlet ports and M14x1.5 threaded fittings, the tank is designed for serviceability and reliable sealing when installed with the included O-rings and recommended Teflon tape.

How does the EVIL ENERGY overflow tank protect my cooling system?

By providing a dedicated reservoir for surplus coolant, the tank prevents coolant loss and limits air entry into the radiator. That helps the system maintain proper pressure and reduces the risk of localized overheating without altering factory plumbing.

• 2L capacity holds excess coolant during thermal expansion
• Barbed 12 mm inlet/outlet ports for secure hose connections
• M14x1.5 threaded drain/side ports allow easy flushing
• Aluminum construction resists corrosion and adds durability

How straightforward is installation and routine maintenance?

Installation is typically quick for anyone familiar with basic coolant plumbing: locate a suitable mounting point, attach hoses to the barb fittings, and seal threaded ports with Teflon tape if desired. Routine maintenance is simple — the bottom drain plug provides fast flushing and the visible level hose makes checking fluid easy.

• Includes barb fittings and O-rings to help ensure a leak-free seal
• Bottom drain plug enables full cleaning without removing the tank
• Visible level hose for quick visual checks of coolant volume
• Compact footprint fits many engine bays — measure before buying

Can this tank be used for things other than coolant?

Yes — aside from coolant recovery, the reservoir can serve as a small oil catch or collection tank in some setups, capturing impurities and sludge from PCV or intake systems. Always confirm suitability for your purpose and ensure compatibility with the fluids handled.

• Works as a coolant overflow or small oil collection reservoir
• Aluminum interior is easy to flush and resistant to staining
• Drain and side ports let you remove trapped contaminants efficiently
• Not a sealed pressure radiator cap replacement; use as a recovery tank

Who is this for? The EVIL ENERGY 2L coolant overflow tank is aimed at DIY mechanics, performance enthusiasts, and technicians who want a durable, serviceable expansion reservoir to manage coolant overflow or capture small volumes of oil/contaminants. If you need a compact, easy-to-install aluminum reservoir with clear level monitoring and practical servicing access, this tank delivers a cost-effective solution—just verify fitment and hose sizes before ordering.
