Overflow tank dome end with site glass

Black over brass overflow tank on 2" diameter with dome end and adjustable mounts.  Select the length and/or preferred site glass for coolant level viewing.  We place them close to the top but let us know if you want the "Distiller's edition" 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 to cart
