VehiMata Coolant Reservoir Tank 2L Aluminium Silver — Fully Welded Radiator Overflow with Threaded M14 Fitting

This silver 2-liter overflow tank from VehiMata is made from aluminum and built for universal fitment on most vehicles with adequate mounting space. It replaces or upgrades plastic reservoirs by offering a metal body, threaded M14*1.5 male-to-barb fitting and compatibility with 3/8" ID hose. The tank uses a bottom port for radiator return and a top port for overflow, and includes O-rings on fittings and a threaded, gasketed cap for a tight seal.

How does this coolant reservoir work with my radiator?

The VehiMata tank captures coolant pushed out of the radiator when system pressure rises above the cap setting. When the engine cools and pressure drops, stored coolant can flow back into the radiator, maintaining fluid level and reducing air entry into the cooling loop.

• Bottom port connects to radiator overflow line for return flow.
• Top port vents overflow into the tank during high pressure.
• Threaded M14*1.5 male-to-barb fitting works with 3/8" ID hoses.
• Sealed cap and O-ring prevent leaks and maintain a closed environment.

What materials and build details matter for durability?

The tank’s aluminum construction resists cracking and heat-related deformation that can affect plastic reservoirs. VehiMata fully welds seams and threads in an O-ring gasketed cap and drain plug to reduce the chance of coolant loss at connection points.

• Aluminum body for improved heat and impact resistance.
• Fully welded seams and threaded, gasket-sealed cap and drain plug.
• O-rings on barb fittings for secure hose attachment.
• Teflon tape recommended at interfaces to enhance airtightness.

How simple is installation and what should I check before buying?

Installation is straightforward for anyone familiar with radiator overflow plumbing: attach the overflow hose to the barbed fitting, secure the tank in an available space, and verify all seals. Before ordering, confirm you have roughly 2 liters clearance and a suitable hose route to the radiator’s overflow outlet.

• Requires adequate mounting space—measure before purchase.
• Works with standard 3/8" ID fuel/coolant hose runs.
• O-rings included; use additional thread tape for extra sealing.
• Consider VehiMata replacement parts for best compatibility.

Will this tank help prevent leaks and air in the cooling system?

The sealed cap, O-ring gaskets and welded construction reduce leak points compared with many stock plastic tanks. By storing and returning overflow fluid properly, the reservoir helps limit air pockets from forming in the cooling circuit during temperature cycles.

• Tight-closed cap and thread-sealed fittings minimize leakage risks.
• Properly routed return prevents air intake into the radiator.
• Regular inspection and Teflon tape at fittings enhance reliability.

Who is this for: Drivers, DIY mechanics and performance enthusiasts who want a durable, metal radiator overflow tank to replace aging plastic reservoirs or to upgrade cooling system reliability. It’s suited for most vehicles with available mounting space and for anyone wanting a sealed, 2L aluminum option with standard hose compatibility and easy installation.
