if the translucent reservoir is filled to the "full cold" mark, and the dip tube on the cap is in place the system will belch itself~....else a weak waterpump, restricted flow (from prior overheat) or bad coolant could precipitate this condition~

recommend a new temp sender for your fan troubles~

sorry none of those seem to be for the Optima...simply ask at your auto parts store...they'll give you the right one~

Will belch with a clean two way cap, otherwise squeeze fat hoses while idling and cap off, look for bubbles in resover and add coolant as needed
