Chase Bays Coolant Overflow Reservoir - S13/S14/S15.

The Chase Bays Aluminum Coolant Overflow Reservoir holds a unique set of innovative features. A common side effect of spirited driving is most coolant overflows quickly fill up, and spew coolant out of the cap under heavy use, leaving you with an engine bay to clean. The reason this happens is the rapid spike in coolant temperature pushes through the radiator cap. To solve this problem, we’ve created a way to control this chaos. The bottom of the overflow has ¼ hose barb inlet and outlet fittings. Inside the overflow, the outlet tube extends up 1" from the fill cap.

This expels any fluid through the outlet fitting and to your desired location (to ground or secondary Chase Bays Coolant Overflow). For more info, please view our video below. Our Coolant Overflow has a very sleek (8”x3”) and aesthetically pleasing design. It is constructed of all 6061 aluminum with a black anodized coating. This is sure to accent any engine bay, regardless of your color scheme or engine setup.
