My 88 90Q is doing the same thing!!!!

Was going to ask, but I hadn't had time to check it.

The squeal doesn't actually start until the engine fires.  If you're just
cranking it, no noise.  It sounds almost like an alternator bearing or
something...but I haven't had time to trace it.

The noise goes away after a couple of minutes, and is present immediately
after you shut the car off and re-start it...warm or cold.

Ideas??
