VehiMata 1L Aluminium Coolant Reservoir Tank — Black, Fully Welded Overflow Can with M14x1.5 Fitment

VehiMata's 1L black aluminum coolant reservoir tank is a compact, fully welded radiator overflow can designed to capture excess coolant and maintain a sealed cooling system.

This lightweight 1-liter overflow tank replaces brittle plastic reservoirs and provides a corrosion-resistant, tightly sealed container for excess engine coolant. Machined for a M14x1.5 male-to-barb fitting and sized for 3/8" inner-diameter hoses, the tank fits many vehicle layouts—check available space before purchasing. Supplied with O-rings and a threaded drain plug, the unit is built to minimize leaks and simplify installation.

How does this overflow tank control excess coolant?

The tank collects coolant that escapes the radiator when pressure rises above the cap setting and stores it until the system cools and can draw fluid back. The lower port receives overflow from the radiator while the top port vents back when pressure normalizes.

• 1L capacity for compact engine bays
• Bottom port accepts radiator overflow; top port allows return flow
• Works with common 3/8" ID coolant hoses
• Sealed with O-rings and fully welded seams to reduce seepage

What fittings and hardware are included for installation?

The reservoir comes pre-threaded for an M14x1.5 male-to-barb fitting and includes O-rings on barb fittings and on the drain plug to improve sealing. Teflon tape is recommended on threaded joints to further prevent leakage at interfaces.

• Pre-threaded M14x1.5 male-to-barb connection
• O-rings on barb fittings and drain plug for a secure seal
• Fully welded body—no adhesive seams that can fail over time
• Cap designed to maintain a closed environment under normal operation

Will this tank fit my vehicle and cooling layout?

The tank is engineered to be compatible with a wide range of cars, trucks, and custom builds, but fitment depends on available space and hose routing. Measure clearance around your current reservoir location and confirm 3/8" hose compatibility prior to purchase.

• Compact footprint suits tight engine bays
• Designed for standard 3/8" ID coolant hoses
• Universal-style mounting—requires basic brackets or clamps
• Confirm clearance and thread compatibility before installing

How does VehiMata ensure leak resistance and durability?

The container is fully welded and uses O-ring gaskets at all threaded interfaces to minimize leaking. The anodized black aluminum resists corrosion and road exposure better than many plastic options.

• Fully welded aluminum construction for structural strength
• O-ring-sealed fittings and threaded drain plug included
• Use Teflon tape on threads to enhance airtightness
• Anodized finish improves corrosion and wear resistance

Who is this for? VehiMata's 1L aluminum coolant reservoir is ideal for vehicle owners who want a durable, compact overflow solution—enthusiasts replacing cracked plastic tanks, custom builders routing compact cooling systems, and anyone seeking a corrosion-resistant upgrade. If you have limited space, use standard 3/8" hoses, and want a tightly sealed overflow container with simple installation hardware, this reservoir is a practical choice. Always verify the fit in your engine bay and consider pairing with other VehiMata components for matched compatibility.
