15" black - site glass OT
Black over brass, 2" diameter with flat ends. First select the length and add to the cart and then select the preferred site glass for coolant level viewing. 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 chamber.
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.
