My alternator belt whines really loud. When I had a tune up about 3 weeks ago, I had my mechanic take a look at it. He said that the belt was in good shape and that the bushings looked fine too. He said it was whining because it was loose; so he tightened it. It sounded great for about a week, but then slowly started to whine again. Now it's just as bad as before he tightened it. Is there a procedure for tightening it in the Bentley Manual, if so what page? It's 3am and I don't feel like going out to the garage right now ;) What would make it become so loose again in just three weeks?

it lasts a few weeks as i recall. i recently finally had my belts replaced, but before than i was using the belt dressing to keep them quiet - they were pretty sqeeky and old. i probably sprayed a little on about once a month or so - and i drive a lot. the stuff comes with one of those narrow aiming tubes you put on the nozzle of the can so you can accurately direct the stream of dressing. and the can is under 2 bucks, so you havent got a lot to lose by trying it. give it a shot! :)

Theres a 13mm bolt at the bottom of the alternator. I get to it underneath the car. Loosen that.
Then take off your air box (2 10mm nuts) and their is a gear and bracket kind of adjuster. Its a 17mm on one side and a 13mm on the other I do belive. One way makes the alternator go up. THe other make it go down.
Sold it.
