For the Forum Crowd & Readers Full technical breakdown
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 directly 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.
The Chase Bays Coolant Overflow inlet and outlet ports are designated by the location of the overflow outlet tube within the Coolant Overflow. The overflow outlet tube will be on the left with the ¼" hose barbs facing you, therefore the inlet is the right barb and outlet is the left barb.
YES this is Formula Drift, NASA, and FIA approved.
Available with five different bracket design options making installation on any chassis a breeze, see photos below for each bracket type.
Hard driving turns your overflow into a sprinkler.
Push the car hard and coolant temps spike. Expanding coolant shoves through the radiator cap, the overflow fills fast and spews out the top. Factory plastic overflows make it worse: they crack, come in awkward shapes and sit in the worst spot in the bay.
