Thanks, Airjer.
Early this morning before I read your thread I had an idea and decided to try it. I thought the only difference between pre-tranny fluid and post is that there was paint on the pulleys. Also, to make matters more interesting, after wire-brushing the redisue off, and thus as a result, the rest of the paint, the squeal has gotten worse. So, my thought is that a good coat of paint acts as a buffer, if you will, padding the belt from the metal. Maybe it's a long shot. So, I painted the pulleys with engine paint and now I'm waiting fot it to dry before I replace the belt.
If that doesn't work I'll try the dielectic grease (it's silicone-based, right?) as a last resort, before I buy a new crankshaft pulley.
I'll keep you posted.
