Replaced thermostat in 2004 Kia Sedona, and it didn't help my situation. Van is still blowing cold air w/ a change to "luke warm" air every so often. Temp gauge still fluctuating, has never overheated-but will get really warm, and then temp will go back down after accelerating. No leaking or overflowing of antifreeze, and no antifreeze in oil either. What's going on? SOMEBODY PLEASE HELP ME?
