15in Polished Stainless Overflow Tank

The 15in Polished Stainless Overflow Tank by Racing Power Co-Packaged is a precision coolant recovery system designed for high-performance engines and custom cooling applications. This polished stainless steel tank serves as a critical component in modern engine cooling circuits, capturing excess coolant as the system heats up and contracts during cooling cycles. Built for automotive enthusiasts, professional mechanics, and performance builders, this overflow tank ensures proper coolant level management while maintaining a clean, professional appearance under the hood.

Constructed from polished stainless steel, this 24 oz recovery tank resists corrosion and maintains its mirror finish even under demanding underhood conditions where temperature fluctuations and moisture accelerate degradation in lesser materials. The 15-inch height and 2-inch diameter bore are engineered to accommodate typical overflow volumes while fitting within standard engine bay dimensions, and the polished finish reflects both durability and aesthetic refinement. Racing Power Co-Packaged's design ensures reliable coolant capture, preventing air ingestion into the main cooling system that can cause cavitation, overheating, and premature water pump failure—critical concerns in both street and competition applications.

This overflow tank benefits muscle car restorers, street rod builders, and performance engine swappers seeking OEM-style or period-correct cooling components with upgraded materials. Installation involves routing the overflow hose from the radiator cap to the tank inlet, with a return line feeding back to the radiator when coolant cools and contracts, maintaining system pressure stability. The polished stainless construction makes it ideal for engine bays where components are visible, complementing custom cooling setups, show builds, and high-performance street vehicles where both function and finish matter equally.
