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

The tank is well designed. A min/max level or sight glass would be an amazing add on. That seems like an oversight.

High Quality Part's
When I ordered the Chase Bays overflow tank for my Skyline. I didn't except the quality of the tank and brackets. These are very clean and well built. Now I'm getting there Washer and Breathers also.

Coolant overflow
Definitely a super clean and well built coolant overflow. The cap is really nice and provides easy opening. The black is clean and compliments the engine compartment well. I'm getting the oil catch can next.
