This actually happen to me last week. I heard a bit of squeaking from a the pulley and was going to check it over the weekend. Didn't make it cause the following day I actually heard someimg fly off and down the road and lost powering steering. I had towed and it turns out the alternator pulley came off. This alnerator has 150,000 miles on it  |
The cap is a dust/debris shield to keep crud out of the inner workings of the pulley.
