I've been meaning to change the fan belts on the 2.8 for a while. I found a couple of new belts that came with the car a few years back. They will fit but the alternator will not line up. The belts are marked up as 975mm. One of the belts on the car is marked as 1000mm which is what the circumference measures. Looking on ebay most sellers of 2.8 belts are selling 975mm items although a couple are the slightly bigger item. Just wondered what other owners have fitted. I had the same problem with the 2.0 a year or so ago that listed items were too small, seems a bit odd!
