EVIL ENERGY Coolant Overflow Tank 1L Black — Aluminum TIG-Welded Reservoir with M14x1.5 Barb

EVIL ENERGY Coolant Overflow Tank is a 1-liter, TIG-welded aluminum radiator expansion reservoir designed to collect and return excess coolant, fitted with M14x1.5 barb threads for 3/8" ID hoses.

This compact black aluminum reservoir provides a durable, corrosion-resistant catch tank for engine cooling systems. Made from fully TIG-welded aluminum with a sealed cap and O-ring, it creates a reliable overflow system for most vehicles. Before ordering, confirm available mounting space and hose routing in your engine bay to ensure a proper fit.

How does this overflow tank work with my radiator?

The tank accepts coolant pushed out by the radiator pressure cap when system pressure exceeds its set point, storing it until the engine cools and the fluid returns. The bottom port connects to the radiator overflow line while the top port serves as the tank vent/overflow outlet for pressure relief. Integrated fittings and seals minimize leaks when installed correctly.

• Bottom port: radiator overflow connection
• Top port: tank overflow/vent
• 1L capacity holds expelled coolant during high-pressure events
• TIG-welded construction prevents seam failure

Will this tank fit my vehicle and hoses?

The EVIL ENERGY tank is marketed as a universal reservoir but fitment depends on space and hose compatibility. It mounts in many engine bays and accepts common 3/8" ID coolant hoses via an M14x1.5 male-to-barb fitting. Always measure the intended installation area and confirm hose routing before purchasing.

• Universal design for most vehicle types
• Male barb thread size: M14x1.5
• Compatible with 3/8" internal diameter hoses
• Compact 1L footprint for tight engine bays

How do I install and seal the reservoir properly?

Installation includes connecting the provided barb fitting and bottom drain plug, each supplied with O-rings to help seal the connections. Threaded joints should be wrapped with Teflon tape to improve airtightness and reduce the chance of interface leaks. Tighten fittings without over-torquing to protect threads and O-rings.

• Use supplied O-rings on barb fittings and drain plug
• Apply Teflon tape to threaded interfaces
• Hand-tighten then snug—avoid over-torquing
• Confirm hose clamps and routing after pressure testing

What materials and quality features does this tank include?

The reservoir is constructed from lightweight aluminum with full TIG welds for strong seam integrity and a durable black finish for corrosion resistance. The cap includes an O-ring gasket to maintain a closed environment and prevent leakage, while the design supports repeat filling and emptying cycles under normal operating conditions.

• Lightweight aluminum body with protective black finish
• Fully TIG welded seams for long-term durability
• Sealed cap with O-ring gasket to prevent leaks
• 1L storage volume suitable for most overflow needs

Who is this for: The EVIL ENERGY 1L aluminum overflow tank is ideal for DIY mechanics, performance vehicle owners, and anyone needing a compact, rugged replacement or upgrade reservoir. It's particularly useful when stock plastic tanks are cracked or when custom cooling setups require a small, reliably sealed expansion tank. Measure your mounting area and hose sizes first to ensure compatibility.
