Introduction
I hope this guide will help you in changing your 2005 Chevrolet Tahoe’s alternator. All of the tools and required parts are listed in this guide as well as pictures to help demonstrate what is happening in each step.
The alternator in a vehicle charges the battery while the car is running. If your alternator goes out, your battery will die, leading to your car not turning on. It is important to replace the alternator for proper function of your car. Be cautious and make sure to follow the steps in order to prevent injury. When working on something in a vehicle, it is always important to disconnect the negative terminal of the battery. Always let your vehicle cool down before trying to work on it. Wait at least two hours from the previous time it was driven before attempting to work. This guide will have your vehicle back in business within an hour if all goes well.
Thank you for viewing this guide; I hope it helps!

The alternator might need a little persuasion to come off the bracket, so use a hammer or a pry bar to aid you in this step.

To accomplish this you will need a hammer to tap your alternator into place.
