Pie Shaped overflow tank 1930-1932 Ford

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.

Aftermarket radiators

When we sell one after the fact or for another manufacturer's radiator we will ship out two tabs that should be riveted or screwed to the sidewall and then our tank will be mounted to that.  You must have 1/2" below the the upper bracket and 1" above the lower brackets.  Aftermarket radiator that do not match Ford's dimensions may not work with this overflow tank.
