How to Remove the Alternator on a 1995 GMC Safari

The alternator on a 1995 GMC Safari generates electricity that is used by the electrical systems in the vehicle and charges the battery. When the alternator goes out, the battery and electrical systems will fail, and eventually you won't be able to drive the van. Fixing the problem involves removing the alternator so that you can have it tested, get it rebuilt or replace it entirely. You will only need a few tools for the job, which should take under an hour for you to complete.

Things You'll Need

• Open-end wrench set
• 3/8-inch breaker bar
• 3/8-inch ratchet and socket set

Instructions

1. Lift the hood and prop it open. Disconnect the negative cable from the battery with an open-end wrench. Remove the positive cable as well using the same wrench.

2. Unbolt the clamps holding the wiring harness to the core support using the 3/8-inch ratchet and socket. Unbolt the upper fan shroud with the ratchet and set it to the side. Unplug the wiring harness on the alternator. Unbolt the positive battery connection on the alternator with an open-end wrench.

3. Locate the tensioner just to the right of the alternator. Turn the tensioner counterclockwise using the 3/8-inch breaker bar and a socket. Pull the belt off the alternator.

4. Unbolt the alternator from the bracket on the engine and lift it out of the engine bay.
