LokoCar Coolant Expansion Reservoir Tank 1L Aluminum Silver — TIG-welded, M14×1.5 leak-resistant overflow

LokoCar's 1-liter aluminum coolant expansion reservoir is a universal, TIG-welded overflow tank that gives a leak-resistant, compact place for excess radiator coolant. This lightweight silver reservoir provides a durable, corrosion-resistant option when an OEM expansion tank needs replacement or when building a custom cooling setup. Machined threads, a sealed cap with O-ring, and a standard M14 × 1.5 male barb fitting make it compatible with common overflow plumbing and hose sizes while keeping installation straightforward for most passenger vehicles and custom projects.

How does this reservoir attach to my cooling system?

The LokoCar tank connects via a male M14 × 1.5 threaded barb that accepts a 3/8" inner-diameter hose. The bottom port functions as the radiator overflow inlet and the top port serves as the tank overflow outlet, letting pressure-driven coolant return or vent as designed.

• M14 × 1.5 male barb thread for standard hose hookups
• Compatible with 3/8" ID coolant hose
• Bottom port = radiator overflow; top port = tank overflow
• Thread O-ring included for initial seal

What build quality and sealing features does it offer?

The tank is fabricated from aluminum and finished in a silver color for corrosion resistance and visual consistency in engine bays. All seams are completed with Tungsten Inert Gas (TIG) welding and the pressure cap thread includes an O-ring gasket; for best results installers are advised to use Teflon tape on threaded interfaces to further reduce the chance of leaks.

• TIG-welded seams for strength and clean joints
• Threaded cap with O-ring gasket for pressure retention
• Teflon tape recommended to enhance airtightness
• Aluminum construction resists rust and keeps weight low

Will this tank work in my vehicle and how much coolant does it hold?

The LokoCar expansion reservoir is sold as a universal part intended to fit a wide range of cars, trucks, and custom cooling setups, but physical clearance must be checked before purchase. It stores up to 1 liter (approx.) of overflow coolant—enough for most passenger vehicle overflow duties without taking excessive space in the engine bay.

• 1.0 L overflow capacity
• Universal fitment—measure before ordering to verify space
• Compact profile for tight engine bays and custom projects
• Silver finish for discreet installation or visible styling
