    The Texas Speed Billet Overflow Reservoir is a billet aluminum coolant overflow tank built on the same reservoir body and bracket system Texas Speed uses for its catch cans, so it installs the same way and gives a clean, uniform look in the engine bay. An integrated fill cap sits on top for easy access, and the billet construction is intended for strength and long service.

    Texas Speed notes the reservoir can also serve as an auxiliary fluid tank to increase capacity in a transmission system when extra volume is needed for high-performance or demanding use. Two fittings are included to adapt the tank to common radiator hose sizes: one -6AN ORB to 3/8" (9.5 mm) barb and one -6AN ORB to 5/16" (8 mm) barb. Texas Speed lists no vehicle fitment, so it is a universal part for custom installation.

    FAQ

    What fittings come with the Texas Speed Billet Overflow Reservoir?

    Two fittings are included: one -6AN ORB to 3/8" (9.5 mm) barb and one -6AN ORB to 5/16" (8 mm) barb, which let the reservoir connect to common radiator overflow hose sizes.

    Is the overflow reservoir vehicle specific?

    No. Texas Speed lists no vehicle fitment for it. It is a universal billet reservoir meant for custom installation using the included bracket and AN barb fittings.

    Can the reservoir be used for something other than coolant?

    Yes. Texas Speed states it can be used as an auxiliary fluid reservoir to increase capacity in a transmission system when more volume is needed for high-performance or demanding applications.

    Does it mount like the Texas Speed catch can?

    Yes. Texas Speed builds the overflow reservoir on the same reservoir body and bracket system as its catch cans, so mounting and appearance match a TSP catch can installed alongside it.
