That's a remote fill for a radiator, it's not designed as recovery system.

With a vented lid I guess you could use it for that?It must be vented real well.

A recovery tank is nothing more than a tank with the over flow hose stuck in the bottom. Tank has to vent freely. Coolant will go in and out as the radiator heats and cools down. It's suck right back into the radiator right through the cap.
