Stainless Steel 3X8 Ove rflow Tank

The Racing Power Co-Packaged Stainless Steel 3X8 Overflow Tank (R6571) is a polished stainless steel coolant recovery system designed for high-performance automotive cooling circuits. This 19-ounce capacity coolant overflow tank is ideal for street performance engines, track-focused vehicles, and custom cooling setups where precise fluid management is essential for engine longevity and consistent operating temperatures.

With a height of 8 inches and a diameter of 3.15 inches, this overflow tank is engineered to accommodate coolant expansion and contraction cycles while remaining compact enough for integration into tight engine bays. The polished stainless steel construction resists corrosion from coolant chemistry and humid environments, while the integrated drain valve allows for quick coolant flush procedures and system service without disassembly.

This overflow tank is particularly beneficial for retrofit applications, vintage restorations, and modern street machines where factory recovery tanks may be undersized or incompatible with aftermarket cooling components. By capturing displaced coolant during thermal cycling, it prevents air entry into the cooling circuit, maintains proper fluid levels, and reduces the risk of cavitation and localized boiling in high-flow or high-temperature engine builds.
