EVIL ENERGY Aluminum Coolant Overflow Tank 2L Black — Universal Recovery Reservoir with Sight Hose & M14 Drain

EVIL ENERGY's 2L aluminum coolant overflow tank is a compact, universal recovery reservoir designed to capture excess radiator fluid, simplify maintenance, and help stabilize cooling-system pressure.

This 2-liter overflow tank is a lightweight, black-anodized aluminum recovery reservoir built for universal fitment across many vehicles. It includes 12 mm barb inlet and outlet ports, an M14x1.5 threaded drain/side port, and comes with seal-ready fittings to make installation straightforward. The tank’s visible level hose and bottom-drain access let you check and service coolant without disassembly, while the durable finish resists road grime and heat.

How does this overflow tank fit my vehicle?

The EVIL ENERGY reservoir is made for broad compatibility but requires a quick pre-fit check. Measure the available space in your engine bay and compare port locations to the supplied dimensions to confirm clearance and hose routing.

• Capacity: 2.0 liters—compact footprint for most cars and light trucks.
• Ports: two 12 mm barb connections for inlet/outlet hoses.
• Threaded ports: M14×1.5 bottom drain and side fitting for secure attachments.
• Recommendation: verify dimensions before purchase to ensure a clean installation.

What are the practical benefits during maintenance?

The tank is designed to make routine coolant checks and flushes faster and cleaner. A detachable bottom drain and an external sight hose reduce the need to unwrap hoses or remove heavy parts when inspecting fluid level or draining the system.

• Bottom drain port enables fast, controlled emptying and flushing.
• Visible level hose provides quick visual checks without opening the cap.
• Barb fittings and O-rings included for leak-free connections out of the box.
• Recommended: use Teflon tape on threaded fittings for extra sealing security.

Will this tank affect cooling performance?

As an overflow and recovery reservoir, the unit helps the cooling system maintain consistent pressure and accommodates expanding fluid, supporting stable engine temperatures. It also serves as a simple collection point for small particulates, helping keep the primary cooling loop cleaner.

• Balances system pressure by capturing expanding coolant during heat cycles.
• Allows recovered coolant to return to the radiator as temperatures normalize.
• Can trap sediments and contaminants away from the radiator core.
• Aluminum construction dissipates heat and withstands under-hood temperatures.

How easy is installation and upkeep?

Installation is straightforward for anyone comfortable with basic engine-bay plumbing. The kit includes barb fittings, drain plug, and O-rings; you’ll want Teflon tape for the threaded connections. Maintenance is simplified by the drain port and sight hose.

• Includes O-ring-sealed barb fittings and bottom drain plug for a good seal.
• Teflon tape advised for threaded ports to prevent seepage.
• Periodic drain and inspection keep the tank clearing out sludge or deposits.
• Lightweight aluminum makes mounting flexible with aftermarket brackets.

Who is this for: This EVIL ENERGY 2L coolant overflow tank suits DIY mechanics, tuners, and professional installers who need a compact, durable reservoir for road cars, project vehicles, or light trucks. It's ideal if you want easier coolant checks and a recovery tank that resists heat and wear without taking much space under the hood.
