Coolant Tank - Overflow/ Recovery 3.0 Dia x 9.0

The Coolant Tank – Overflow/Recovery 3.0 Dia x 9.0 by MOROSO is a precision-engineered coolant recovery system designed for serious engine builders, performance enthusiasts, and mechanics who demand reliable thermal management. This overflow tank captures excess coolant as your engine heats and expands, preventing loss of valuable coolant fluid while maintaining a sealed cooling system. Whether you're running a street performance build, weekend track car, or heavily modified engine, a quality recovery tank eliminates the mess of overflow spills and helps preserve your cooling fluid's integrity over extended driving sessions.

MOROSO's 3.0-diameter tank is engineered with a 9.0-inch height, offering adequate capacity for most performance cooling setups while maintaining a compact footprint for tight engine bay installations. The design features a threaded cap and internal baffle system that allows cooled coolant to naturally return to the radiator as engine temperatures drop—a critical feature that eliminates air pockets and maintains proper coolant circulation. The tank's durable construction handles thermal cycling stress without degradation, ensuring consistent performance whether you're dealing with aggressive cooling modifications, high-output engines, or extended high-temperature operation. The lightweight design at 1.37 lbs minimizes parasitic weight while the compact 5.1 x 4.85-inch footprint makes it ideal for constrained engine bays on vintage restorations, forced induction builds, and modern performance platforms alike.

This recovery tank benefits drag racers, road course competitors, and street enthusiasts running modified cooling systems or non-OEM radiator setups. Installation requires basic mechanical knowledge—mount the tank in an accessible location near the radiator, connect the overflow hose from the radiator filler neck cap, and run a return line back to the lower radiator hose or coolant inlet. Compatible with custom cooling loops, upgraded radiators, and high-performance thermostat housings, the MOROSO tank works across domestic and import platforms. Proper installation prevents coolant loss, reduces oxidation from air exposure, and extends radiator and water pump life by maintaining stable system pressure and temperature control.
