When we made this overflow tank we stared at it and said, "Egad! It looks like a reflux column on a still." And behold, the "Distiller's edition" was born; a black over brass 2" OD coolant recovery tank with dome end, adjustable mounts and site glass(es) to see what's going on in there. Select the length and/or preferred site glass for coolant level viewing and then tell us how many site glasses you want.  Made in the USA.

Here is how it works...should the system pressure exceed the cap’s rating, the spring will compress and fluid will flow through the upper tube to fill the expansions tank.

In the event the recovery tank reaches 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.

WHEN ORDERING Select the tank length and add to cart.  Then select the site glass size and add as many as you want to the cart.

Contact us directly for alternative sizes, finishes shapes or anything cool you want made.
