OT - hidden expansion tank

Regular price
We designed this coolant recover tank to be hidden.  It is nested inside a fan shroud and due to its horizontal orientation uses a series of baffle to keep the fluid from escaping.
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.

Contact us directly for alternative sizes, finished or shapes.

We make to order. Please allow adequate time for us to build.
