EVIL ENERGY 2L Aluminum Radiator Coolant Overflow Tank – Black Universal Coolant Recovery Reservoir

Maintain Proper Coolant Recovery and Expansion

As engine temperatures rise, coolant expands and cooling system pressure increases.

In conventional radiator-cap recovery systems, the pressure cap controls coolant flow into the overflow reservoir. As the engine cools, the radiator can draw coolant back from the reservoir if the system is properly configured.

A correctly installed coolant recovery tank helps reduce coolant loss and supports consistent coolant levels.

The EVIL ENERGY aluminum reservoir can be incorporated into compatible systems to collect and store expanding coolant.

Important: An overflow reservoir does not directly lower engine temperature, replace a malfunctioning radiator cap, or regulate cooling system pressure by itself.

The vehicle’s radiator, thermostat, cooling fans, water pump, and pressure-control components must all function correctly.

Universal 2L Aluminum Reservoir for Custom Cooling Systems

The EVIL ENERGY 2L coolant overflow tank is designed for universal installation rather than direct replacement of a particular factory reservoir.

It is particularly useful for vehicles with modified cooling system layouts, aftermarket radiators, or limited space for factory coolant bottles.

Common applications include:

• LS engine swaps and custom V8 installations

• Modified Honda Civic and Acura Integra cooling systems

• Nissan 240SX and SR20DET engine builds

• Toyota Supra and Lexus IS300 performance projects

• Ford Mustang and Chevrolet Camaro cooling upgrades

• Turbocharged and supercharged engine compartments

• Custom street cars, race cars, and restoration projects

Because the tank uses a universal design, installation may require custom mounting brackets, hose routing, or adapters.

Dual 12mm Hose Barb Connections

The EVIL ENERGY coolant reservoir features two 12mm hose barb connections intended for compatible coolant plumbing.

The barb fittings provide connection points for properly sized hoses secured with suitable clamps.

The tank also includes M14×1.5 threaded ports at the side and bottom.

The supplied fittings and drain plugs incorporate O-ring seals to help prevent leakage when properly installed.

Installation note: Verify the supplied port arrangement and the intended coolant flow path before connecting the reservoir. A coolant recovery tank must be configured correctly for the vehicle’s cooling system design.

External Coolant Level Indicator

The integrated visual level hose allows owners to inspect the reservoir’s coolant level without repeatedly opening the tank.

This is especially convenient on vehicles with tightly packaged engine compartments or custom reservoir mounting locations.

Monitoring coolant levels can help identify gradual coolant loss, improper recovery operation, or potential cooling system problems.

Always check coolant levels according to the vehicle manufacturer’s instructions, generally with the engine cold.

Convenient Bottom Drain for Easier Maintenance

The EVIL ENERGY 2L aluminum coolant tank includes a bottom drain connection designed to simplify reservoir servicing.

Rather than removing the entire tank, owners can drain collected coolant through the bottom port when the engine is completely cool and the system is safe to service.

The drain feature can also make periodic cleaning easier when deposits accumulate inside the reservoir.

Always collect used coolant in a suitable container and dispose of it according to local regulations.

EVIL ENERGY 2L Coolant Overflow Tank Specifications

Overall tank dimensions, mounting bracket details, cap pressure rating, and maximum operating pressure were not supplied. Confirm these specifications before installation, especially on pressurized cooling systems.

What Vehicles Does the EVIL ENERGY 2L Coolant Tank Fit?

This reservoir is a universal aftermarket component and is not guaranteed to directly replace a factory coolant expansion tank.

Fitment warning: Many modern vehicles use pressurized expansion or degas tanks that are integral to the cooling system. This universal reservoir should not replace a factory pressurized tank unless its pressure rating, cap design, hose configuration, and intended function are explicitly compatible.

How to Install a Universal Aluminum Coolant Overflow Tank

1. Allow the engine to cool completely before opening or modifying any cooling system components.

2. Measure the available mounting space and verify adequate clearance around the reservoir.

3. Select a secure mounting location away from exhaust components, moving belts, and excessive heat.

4. Identify the vehicle’s coolant recovery or expansion plumbing arrangement.

5. Install the supplied hose barb fittings and drain plugs using their specified O-ring seals.

6. Connect compatible coolant hose to the appropriate ports and secure it with suitable clamps.

7. Mount the reservoir securely using compatible brackets and hardware.

8. Fill the cooling system according to the vehicle manufacturer’s procedure.

9. Bleed trapped air where required and verify coolant recovery operation.

10. Inspect the tank, hoses, fittings, and drain connections for leaks after the engine reaches operating temperature and cools again.

Do not apply PTFE tape indiscriminately to O-ring-sealed fittings. Use only the sealing method specified by the manufacturer, since unnecessary tape can interfere with proper seating.

Can This Tank Be Used as an Oil Catch Can?

EVIL ENERGY also advertises the reservoir for certain oil collection applications.

However, a coolant overflow tank and a properly engineered crankcase oil separator serve different purposes.

An oil catch can typically requires appropriate internal baffling or filtration, crankcase ventilation connections, and resistance to oil vapor and engine vacuum.

This 2L reservoir should not be treated as a direct replacement for a PCV oil catch can unless the manufacturer confirms the necessary compatibility and operating specifications.

For dedicated crankcase oil separation, choose a purpose-built oil catch can.
