today ,I was doing my new fog light and discovered there was a tank on the opposite end of the wind shield liquid tank where is located right behind the left/driver side fog light and you can only see it from bottom of the car if you lift the car up.

what is that? any one?

 

coolant expansion relief tank. If the engine coolant expands it blows off into it, on cooling it gets sucked back into the coolant system.
