EVIL ENERGY aluminium radiator coolant overflow tank 2L Silver — universal fit, corrosion-resistant sight hose

EVIL ENERGY's 2L aluminum radiator coolant overflow tank is a universal coolant recovery reservoir designed to manage engine coolant expansion and provide an easy-to-monitor, serviceable overflow solution.

This lightweight 2-liter aluminum recovery tank is built for universal fitment across many vehicles; it gives a corrosion-resistant alternative to plastic overflow bottles while keeping coolant level visible and serviceable. With 12 mm barb inlet/outlet ports, an M14x1.5 threaded drain, supplied barb fittings and O-rings, and a side-mounted visual level hose, the unit is engineered for straightforward installation and periodic maintenance.

How will this reservoir fit my vehicle?

The EVIL ENERGY tank is made as a universal expansion tank, so it suits a wide range of cars, trucks, and performance builds. Before purchase, measure the intended mounting location and compare port spacing to ensure clearance and hose routing.

• 2-liter capacity for compact installations where space is limited
• 2 × 12 mm barb ports for common coolant hoses
• Bottom and side M14×1.5 threaded ports for drain or sensor use
• Aluminum construction fits many aftermarket setups and custom installs

What ports and fittings are included, and how do I seal them?

The package includes barb fittings and bottom drain plugs with O-rings to create a reliable seal right away. For additional leak protection on the threaded connections it is recommended to use Teflon tape or an appropriate thread sealant during installation.

• Two 12 mm barb inlet/outlet connections supplied for hose attachment
• M14×1.5 threaded drain and side port compatible with standard fittings
• O-rings included to prevent immediate seepage at supplied fittings
• Recommended: apply Teflon tape on external threads for long-term sealing

How is maintenance handled and what inspection options are there?

Cleaning and inspection are straightforward: the bottom drain port allows flushing of sludge or deposits, while the external visual level hose displays coolant volume without removing the cap. Routine checks help prevent buildup and ensure the cooling system operates efficiently.

• Bottom drain plug enables convenient flushing and debris removal
• External sight/level hose shows coolant height at a glance
• Aluminum body resists warping and endures under engine-bay heat
• Can be used as an oil-collection or catch tank in custom applications

Will this part affect engine performance or coolant balance?

The main role of an overflow tank is to manage expansion and contraction of coolant under temperature changes, helping the cooling system maintain proper pressure balance. While not a performance part by itself, a well-functioning recovery tank contributes to consistent coolant levels and temperature control, supporting engine reliability.

• Provides a place for excess coolant to expand and be drawn back when cooling
• Helps reduce air ingestion into the cooling circuit when installed correctly
• Can collect sludge or contaminants when used as a secondary collection reservoir
• Does not replace a pressurized radiator cap or primary cooling components

Who is this for: The EVIL ENERGY 2L aluminum coolant overflow tank is aimed at DIY mechanics, tuners, and vehicle owners who want a durable, serviceable alternative to OEM plastic reservoirs. It's especially useful for compact engine bays, custom-fabrication projects, track and performance builds, and anyone seeking an easily inspected overflow solution. Always confirm measurements and hose compatibility before installation to ensure proper fit and function.
