Won't suck the water from overflow

The cap has a tiny little silver or brass looking valve on it. When an engine is hot, and some coolant flows over to the bottle, that little valve allows the coolant to be drawn back into the engine as it cools down.

Yours may be bad. Also, since it is done thru a vacuum, make sure you have a tight seal throughout the over flow hose and clamps. If not, it will suck air and not coolant back into engine.
