EVIL ENERGY Radiator Coolant Overflow Tank 2L - Durable Aluminum

In this review the EVIL ENERGY Radiator Coolant Overflow Tank is assessed for DIY mechanics and enthusiasts who want a simple, durable coolant recovery solution. The bottom line: it is a well-made 2L aluminum expansion tank that improves coolant level visibility and makes maintenance easier, but buyers should confirm fitment before ordering. The tank's main appeal is a sturdy alloy construction with practical features like a visual level hose and a bottom drain port that simplify cleaning and fluid checks.

Key Features

• Universal application: Designed as a universal coolant expansion tank so it can fit many vehicles when there is adequate space for installation.
• 2L capacity: The 2 liter volume handles typical overflow needs without taking excessive engine bay space.
• Barb and thread fittings: Two 12 mm barb inlet/outlet ports plus M141.5 threaded bottom drain and side port make plumbing and draining straightforward.
• Easy cleaning: The bottom drain port allows quick flushing of the tank, helping remove sediment and sludge accumulated during service.
• Visual level hose: A transparent hose gives fast, at-a-glance monitoring of coolant level so topping up is simpler and less guesswork.
• Leak sealing: Barb fittings and drain plugs are supplied with O-rings to improve sealing during installation.

Who It's For

This tank is best for home mechanics, tuners, and anyone replacing a worn plastic reservoir or adding a recovery tank to an older cooling system. It suits vehicles where an aftermarket aluminum tank will fit into the available space and where users value durable construction and easy maintenance.

It is not ideal for buyers who need a guaranteed direct-fit OEM replacement for a specific modern model without modification; several customers reported fitment can vary and some experienced leakage when not correctly sealed or when vehicle mounting points differ.

Pros & Cons

Pros

• Solid build and good welds give confidence in long-term durability.
• Easy to install for most DIYers, with supplied barb fittings and O-rings.
• Visual level hose and bottom drain simplify monitoring and cleaning tasks.
• Can double as an oil collection tank to trap impurities and sludge, helping engine longevity.

Cons

• Fitment is mixed across different vehicles, so measuring and test-fitting are necessary before purchase.
• Some users reported leakage when installation sealing was imperfect, so careful use of Teflon tape and O-rings is required.

Specifications
