We designed this pie-shaped overflow tank to nest against the sidewall and fit inside the 1930-32 Ford Radiator shell.

Why?

Because when you oversize your fan you may interfere with the standard overflow tank placement. This 1.3 pint solution mounts between the upper ear and lower bracket and fully utilized the shape of the shell to maximize the volume of coolant. Please designate which side of the radiator e.g. driver or passenger when ordering. Made in America.

Where does it go and how does it work?

Our discreet pie-shaped overflow tank nests between the radiator sidewall and the shell. It’s unique shape follows the shell’s contour to maximizes the fluid capacity and the flat black color helps it blend into the engine compartment. 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 ~1.3 pint 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.

How does this mount?

When we manufacture a pressurized model A we integrate the tabs into the return flange of the sidewall and utilize riv-nut fittings.

When we sell one after the fact or for another manufacturer's radiator we will ship out two tans that should be riveted or screwed to the sidewall and then our tank will be mounted to that
