Went down to Ma. last Thursday to see Mother just out of the hosp. On the freeway I heard a bump, then flopping belt noise. All the lights on the dash light up...CRAP! I took the next exit, but not before I pegged the temp gauge. Coasted into a Dunkin donuts, called AAA, and got towed to Mothers house. Looked like the top idler pulley bearing gave it up, then the belt got fried. All that was left of the bearing was the center race. Luckily, the local Saab dealer had a pulley...$54.00. They wanted $78.00 for the belt! Autozone had it for $25.00. The 2.3 engine seems fine. I expected to find a blown head gasket, or worse when I started it. Lesson: Check all idlers for play. I found the center idler has a little play in it. That will be replaced soon. Also, it’s much easier to get the belt around the crank pulley if you remove the wheel and one piece of plastic in the wheel well. It ran perfectly all the way back to Vt.
