Overflow Tank Stainless 2in x 10in Black

The Overflow Tank Stainless 2in x 10in Black by RACING POWER CO-PACKAGED is an essential cooling system component for any serious engine builder or performance enthusiast. Whether you're running a carbureted street engine, a high-output naturally aspirated build, or a forced induction setup, this overflow tank captures excess coolant expelled under thermal stress and returns it to the system as temperatures normalize. This simple but critical component prevents coolant loss, maintains proper fluid levels, and protects your engine from overheating during sustained driving or competition use.

Constructed from stainless steel, this overflow tank resists corrosion and internal rust that compromises coolant chemistry and circulation. The 2-inch diameter opening accommodates standard hose fittings found on most domestic and import cooling systems, while the 10-inch length provides adequate volume to handle coolant displacement without triggering pressure relief valves prematurely. The black finish blends seamlessly into engine bays and resists discoloration from heat, road grime, and UV exposure. Weighing only 1.62 lbs when empty, the compact 7.8 x 2.45 x 17.5-inch profile allows flexible mounting on frame rails, inner fenders, or custom brackets without interfering with throttle linkage or fuel lines.

This overflow tank works best in carbureted engines, early fuel injection applications, and custom cooling systems where OEM plastic tanks are undersized or unavailable. Street rods, classic muscle cars, vintage imports, and drag racing builds benefit from the durability and reliability of stainless construction, especially when running high-flow water pumps or extended idle periods. Installation is straightforward: connect the upper hose from your radiator filler neck, run a lower return line back to the radiator inlet or water pump, and secure the tank to the engine bay with simple brackets. Verify hose compatibility before purchase and ensure your radiator cap is rated for your cooling system pressure to prevent siphoning issues.
