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 engineered for high-performance automotive cooling circuits. This 19-ounce capacity coolant overflow tank delivers reliable coolant level management for street performance engines, track-focused vehicles, and custom cooling setups where precision fluid management is critical to engine longevity and consistent operating temperatures.

Measuring 8 inches tall with a 3-inch diameter core, this overflow tank is sized to handle coolant expansion and contraction cycles while remaining compact enough for engine bay integration in tight installations. The polished stainless steel construction resists corrosion from coolant chemistry and humid engine environments, while the integrated drain valve enables quick coolant flush procedures and system service without disassembly. The compact 1.99-pound weight and modest 7.95 x 3.15 x 17.65-inch profile make it suitable for retrofit applications, vintage restorations, and modern street machines where factory recovery tanks are undersized or incompatible with aftermarket cooling components.

This overflow tank addresses a specific cooling system need: capturing displaced coolant during thermal cycling 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. The stainless steel construction and polished finish also serve cosmetic purposes in show vehicles and engine bays where appearance matters alongside function. Suitable for street rods, muscle car restorations, custom builds, and performance street engines where aftermarket cooling refinement enhances both reliability and visual quality.
