Just ordered a new thermostat and a 32mm flat wrench (for the fan) to prepare to do this myself. The cars been sitting for a couple weeks so I thought I'd take it for a short trip around town. Of course the thermostat works fine and the car operated at normal temperature. At least I'll have what I need to fix it if it acts up again. And I'm pretty sure it will. These things often repeat themselves.
I just stopped in to see what condition my condition was in.
