My XJ does the same thing...the belt is tight, but when I start it in the AM, it sqweeeeels, so I leave it off until I hit RPM, then turn it on. No problemo then. Any time during after starting it, if I start it with the A/C on, no problem. Keep in mind that it is already 90* at 6 AM here in the hubs of hell Arizona, so that may be why the A/C doesn't want to wake when I do. Park it in the summer, wheel it in the winter. Exactly opposite of you right coasters.
