Answer
Hi Bob -

Alternator replacement is relatively basic. The hard part is always the access. If there is noise coming from it, then I would replace it. First and most important, disconnect the negative side of the battery.

The alternator is removed by undoing the top bolt (this will be the adjustment), and the pivot bolt on the bottom. Unhook the belt from the pulley and put it aside, or even replace it if it is worn or shiny. There should be 2 sets of wires attached to the rear of the alternator, one is a terminal, and one is fastened with an 8mm nut. Remove them both. Once access is gained, the alternator can then be removed.

The new one is replaced reverse of removal.

Hope this helps -
