Note : Steps 1 to 12 and 14 to 20 apply to upgrading to both the 95 and 130-Amp units. Step 13 outlines the additional modifications needed when upgrading to the 130-Amp unit

1. Disconnect the battery negative (-) terminal from the battery and move
it to the side to prevent accidental contact during the installation.
2. Remove serpentine belt. Using an 18mm socket, release the tension on the belt and remove belt from top pulleys including the alternator, idler and air conditioner. The tensioner is located on top and immediately to the right of the alternator. You may wish to leave the belt on the other pulleys until the end so you can see the proper belt path for reinstallation. If not, there is typically a diagram sticker on the radiator support.
3. Remove the cover from the air filter box.

4. Gently remove the regulator plug from the alternator on the car using a tlat-blade screwdriver. This plug will be reused, so be careful not to break the plastic clip.
