2012 Coolant Overflow Bottle Has Two Caps?

you need to connect that bottom hose to the coolant hard pipe above the driver side manifold. I ran mine to a reducer and into the connection where the factory throttle body coolant lines returned (I deleted mine)

Interesting, what is the purpose of this connection, though? Is the overflow designed to return coolant to the system? And what prevents it from coming up from that line (e.g. a one-way valve somewhere?).
