VehiMata Coolant Reservoir Tank — 2L Aluminum Overflow Tank Silver, Fully Welded & Leak-Resistant

VehiMata’s 2L aluminum coolant reservoir tank is a durable, sealed overflow container designed to capture radiator fluid with a secure M14*1.5 fitting and 3/8" hose compatibility.

This compact silver overflow tank replaces or upgrades stock plastic reservoirs with a fully welded aluminum body and tight-sealing cap. It holds up to 2 liters of coolant, uses a bottom port for radiator return and a top port for overflow, and arrives with O-rings on fittings and a threaded drain plug to reduce the chance of leaks. The unit is built for broad vehicle compatibility but needs enough installation space under your hood.

How does the VehiMata overflow tank manage radiator pressure and coolant flow?

The tank works alongside your radiator cap: when system pressure exceeds the cap’s setting, hot coolant is forced through the pressure cap into the overflow tube and into this reservoir. As the engine cools and pressure drops, fluid returns to the radiator through the bottom port. This simple pressure/return principle helps keep the system topped off without open exposure to contaminants.

• Bottom port serves as radiator return; top port receives overflow.
• Fully welded aluminum body resists cracking compared to plastic tanks.
• Threaded M14*1.5 male barb fits the tank cap interface securely.
• Compatible with 3/8" ID hoses for common coolant lines.

What are the installation steps and sealing details I should know?

Install requires a clear space near the radiator or along the inner fender where hoses can reach without sharp bends. The tank includes O-rings on the barb fittings and the drain plug to create a proper seal; use Teflon tape on threaded connections for added leak protection. Make sure all clamps and hose routings are secure before pressure testing the cooling system.

• Verify fitment space and hose reach before mounting.
• O-rings pre-installed on barbs and drain plug for better sealing.
• Use Teflon tape on threads to improve airtightness and prevent leaks.
• Check hose clamps and pressure-test after installation.

Which vehicles and hoses will this 2L tank work with?

The VehiMata tank is designed to be universally compatible with many makes and models, but confirmation of space and hose routing is necessary. It accepts standard 3/8" ID fuel/coolant hoses and uses an M14*1.5 threaded fitting, common in aftermarket and some OEM caps. When in doubt, measure your current reservoir connections or compare thread and hose sizes before purchase.

• Volume: 2 liters—suitable for most passenger cars and light trucks.
• Hose compatibility: 3/8" ID recommended.
• Thread size: M14*1.5 male fitting for cap/barb interface.
• Requires mounting space and proper hose routing inside engine bay.

How does the tank maintain a closed environment to prevent leaks?

The unit ships with a tightly threaded cap, O-ring gaskets, and a fully welded body to minimize leak points. A threaded bottom drain plug with its own O-ring further secures the system. For additional peace of mind, applying Teflon tape to threaded interfaces is recommended to enhance airtightness during installation.

• Fully welded aluminum construction reduces seam leaks.
• O-ring gaskets at barbs and drain plug for reliable seals.
• Tight cap closure prevents contamination and fluid loss.
• Teflon tape recommended on threads to prevent interface leakage.

Who is this for: The VehiMata 2L aluminum coolant reservoir tank is aimed at DIY mechanics, performance enthusiasts, and anyone replacing a cracked or aging plastic overflow bottle. It’s a good option for owners of passenger cars, light trucks, and modified vehicles that need a robust, compact overflow solution. Confirm thread size, hose diameter, and engine-bay clearance before ordering to ensure a straightforward installation.
