Remove the 8 or 10mm bolt I believe in the middle of the cover and you should be able to pull it far enough away to tell. I would say the belt should be good to 100k but being that its so old that will also had to the deterioration of the rubber. So if you need it to be reliable you have to take a peak at it.
