EVIL ENERGY 2L Aluminum Coolant Overflow Tank — Silver compact radiator recovery, corrosion-resistant with 12mm barb fittings

EVIL ENERGY's 2L aluminum coolant overflow tank is a universal radiator recovery reservoir that stores excess antifreeze, lets you monitor fill level, and provides leak-resistant connections for vehicle cooling systems.

This 2-liter silver coolant recovery tank offers a compact, durable replacement or upgrade for many passenger cars, trucks, and performance vehicles. Machined from aluminum for corrosion resistance and lightweight performance, it includes 12 mm barb inlet/outlet fittings and an M14x1.5 threaded drain and side port. Components supplied with O-rings help create a secure seal, and the visible level hose makes quick checks effortless without disassembly.

How does this overflow tank improve coolant system performance?

By giving the cooling system an external reservoir for expanding fluid, the tank helps stabilize pressure and reduce air ingestion during temperature changes. That steady reserve reduces cavitation and allows the radiator and pump to maintain more consistent cooling under load.

• 2 L capacity for overflow and recovery during heat cycles
• Barb inlet/outlet (2 × 12 mm) for secure hose connections
• Bottom drain (M14×1.5) simplifies cleaning and fluid changes
• Aluminum construction resists rust and stands up to engine-bay temperatures

What are the practical installation details I should know?

Installers will find the tank straightforward if there is adequate space in the engine bay. The kit comes with barb fittings and bottom drain plugs fitted with O-rings; using Teflon tape on threaded connections is recommended to enhance the seal.

• Measure available mounting area before purchase to confirm fit
• Use supplied O-rings and apply Teflon tape to threaded ports
• Compatible with standard 12 mm coolant hose on both inlet and outlet
• M14×1.5 threaded side port can accept sensors or additional fittings as needed

How do I maintain and inspect the coolant recovery tank?

Routine checks are quick thanks to the clear visual level hose, and flushing is simple via the bottom drain. Periodic inspection of hose clamps, O-rings, and the drain plug ensures the tank remains leak-free and operating correctly.

• Monitor coolant level through the external sight hose—no disassembly required
• Clean residue and sludge out via the M14×1.5 drain port when necessary
• Replace O-rings and tighten clamps to prevent seepage over time
• Check mounting hardware to avoid vibration-related loosening

Who is this for? EVIL ENERGY's 2L aluminum coolant overflow tank is built for car owners, mechanics, and performance enthusiasts who want a compact, durable reservoir to manage coolant expansion and recovery. It's especially useful for vehicles that see spirited driving, towing, or older cooling systems that benefit from an external recovery point. Make sure the tank's dimensions and port layout suit your engine bay before purchase; with proper fitment, it delivers a robust, easy-to-maintain solution for keeping coolant where it belongs.
