This cylindrical overflow tank was designed for a Lagonda but can be used in a variety of vehicles and in a variety of locations.  It measures 8" in diameter and can be sized to your desired capacity.  

Should the system pressure exceed the cap’s rating, the spring will compress and fluid will flow through the upper tube to fill the chamber.  

In the event the recovery tank reaches maximum capacity, the fluid will find the second tube and exit to the street.  A vacuum will draw the coolant back into the cooling system as the engine cools down.

Made to order in the USA.  Please allow us adequate time to construct this bespoke piece.
