I have a 1993 Ford Taurus that has been having some thermostat related problems. When I went to replace it a few minutes ago, to my suprise, its not located where it should be. Does anyone have any suggestions on where it could be located in my car? It’s a 3.8 Liter. Please help!! Have places I need to be…

In gear or in park, it stalls every few minutes at idle, otherwise runs flawlessly. Immediately, it easily restarts. No "check engine" light or stored trouble codes, and all scan data reads normally until it quits running. It has a 3.0L 12v engine.
