First, the alt is located low on the engine near the firewall. As a result, work has to be done from both the top and bottom of the vehicle. When under the vehicle, make sure the vehicle is securly supported. Here is are the directions I was able to find.

With the ignition OFF , disconnect the negative battery cable.
Unplug the alternator wire harness connector and remove the terminal nut.
Remove the alternator adjusting bolt; loosen the nut on the mount bolt.
Swing the alternator towards the engine; remove the belt.
Remove the bolts holding the alternator bracket to the engine and remove the alternator with the bracket.


To install:

Install the alternator and bracket. Once in position with the bolts finger-tight, install the belt. Tighten the mounting bracket bolts and the alternator mount (pivot) bolt to 33 ft. lbs. (45 Nm).

Let me know if you have other questions.
