6061 Aluminum Coolant Overflow Tank - High Performance Reservoir with Leak-Proof Design

Upgrade your vehicle's cooling system with our premium aluminum overflow tank. Engineered to outperform plastic reservoirs, this durable tank prevents leaks and rust while withstanding extreme temperatures and pressures.

Premium Aluminum Construction

Aircraft-Grade 6061 Aluminum

Manufactured from anodized 6061 aluminum alloy for superior strength and heat dissipation. Unlike plastic tanks that crack over time, our polished aluminum construction maintains integrity even under prolonged use and extreme conditions (-30°C to 120°C).

Leak-Proof Tig Welded Design

Features precision TIG welding throughout with an O-ring sealed cap to maintain a completely closed system. The airtight design prevents coolant loss and protects your engine from overheating due to fluid evaporation.

Smart Ventilation System

Includes a strategically placed 1/16" vent hole for proper pressure regulation while maintaining a sealed environment. The removable cap allows for easy cleaning and reuse, with a lightweight (0.8kg) design that won't strain your engine bay.

Rust Prevention

Aluminum construction actively prevents corrosion in your cooling system, saving you hundreds in potential repair costs. The non-reactive material keeps coolant pure and effective for optimal engine performance.
