What <b>PainTrain</b> said. Is the fan bent? What bent it? Is the bearing in the alternator worn and allowing the shaft to move?
Also, never lube your belts. Belts should be replaced, not dressed, (belt dressing). The money you spend on belt dressing should go toward a new belt. When a belt becomes glazed, replace it. Belt dressing, or other lubes, merely soften the rubber and delay the inevitable.
It is not easy to troubleshoot over the phone, even harder on the internet.
You need to determine why the alt. fan is now hitting.
If the fan is hitting when cold, it should hit when warm also. The clearance is not so much that operating temps will make much difference.
Replace the alternator with a lifetime warranty from a local/national parts house. Replace the belt also, and check the other belts while you are already under the hood. If one is worn, the others might be worn as well. Make sure the alt. mounts are tight, and very importantly,aligned, use the spacer for the fan from the old alt. and look down from the top and make sure all the belts are aligned as I said before. Don't overtighten the belt as that will just help wear the alt. bearings prematurly.
If you can twist the belt upside down in its longest span, it is too loose, but, it should not be as tight as a banjo string either. Your owners manual should have the info you need.
