Great step by step video, I now can't imagine taking my truck in to have a mechanic do this, as simple as this was. Thanks!
Thank you so much for putting up this video. I had to change my alternator on my 2002 Tahoe and was trying to decide if I should try this myself or let a mechanic do it for 150 dollars. Mind you, I've never changed an alternator in my life and it was 12 degrees and windy outside so I had to be absolutely sure I could pull this off. After watching your video I was completely confident. Everything went perfectly and took me about 45 minutes. Probably would have been quicker but I kept running back in my house to get warm. Thanks again!
Vinny I always use their videos for all my repairs. I watch them first to gauge whether I have the tools and confidence to pull it off. They've never failed me.
THANKS!! I knew there had to be a tensioner somewhere but couldn't see where it was. You saved me a couple hours of swearing, and made my day easier.
I am a 39 yr old mom of 3 boys & thanks to you I changed my own alternator on my 2003 Chevy Tahoetwo weeks ago!! You guys made it so easy! I am not one to read directions & be able to fix something. But since I had such a good visual it was EASY! Now I need to figure out what is wrong w/ my husband truck! It starts but then dies. It is not the alternator or the battery. Wish I knew the problem so I could watch another one of your videos to fix it!!
thanks, changed my Alt in 30 mins and saved $200 dollars, it was so easy with the help of this video. Thanks again for posting these videos.
First time ever doing any kind of car work was these past two years, (never had a father teach me anything) learned so much from you guys done it all myself lol feel proud.
+SteezyHG Thanks for checking us out. 1aauto.com
Where do I send the case of beer? This took all of 35 minutes in the parking lot of a strip mall. The only step I had to change was removing that pesky clip after removing the alternator from the mount. Viewer for life, well done.
Great video. I have two things to mention. 1. At approximately 5:34 in, you will notice that a single bolt is inserted as a starting point. This is a huge help. I battled mine for almost 3 hours by not noticing that tid bit. 2. For a diesel disconnect BOTH negative battery cables.
Thank you brother - I haven't ever changed an alternator on a serpentine belt, Now I can and you saved me a lot of cash and help get me back on the road to get back to my jobsite ASAP - THANKS AGAIN!!!
Thanks for checking us out, have a great day! 1aauto.com 888-844-3393
I've watched several of your videos. Today I found my alternator had died. Thanks to your video, I was able to replace the alternator with little effort. I did get my 15mm socket wrench wedged by the fan shroud. However, I was able to complete the rest of the swap and when I put the belt back on, I got the wrench out easily. Thank you so much for your videos!

Jim Oltman funny as the same thing happened to me... Couldn't get it on... Then it slid right off
I am not much of a mechanic. I recently had to replace the alternator on my 2002 Chevy Silverado and your video made it very simple for me to do. Thank you very much for your help.
Thanks for watching. 1aauto.com 888-844-3393
Thanks 1AAuto. I watched this video when I replace my alternator in my '04 Silverado. The process wasn't time consuming and it saved me a lot of money. In my mind it looked hard to replace but with your video I did it without a problem. Thanks again 1AAuto. I will be looking at your video on how to replace the tailgate handle.
Thanks for the video. I followed your instructions to remove the alternator. I was able to install the new one during half-time of a football game! I appreciate it.
Thank you for the great reply. We love to empower our customers by showing you how-to perform your own auto repairs while installing our high quality auto parts. Have a great day! 1aauto.com +Hendalee Wilson
BIG thank you to 1aauto for these videos. Unfortunately I didn't have time to order my new alternator from you guys, but your video was a huge help in doing the swap myself. It's an old truck though, next time I need parts I'll give you a call!
+Matt Riddell Thank you for the comment, Matt! We look forward to your call! Any other viewers interested in purchasing this alternator for their vehicle please click the link: www.1aauto.com/1A/alternator/GMC/Sierra/1AEAL00141?RUclips&CTA+Comment&Fzak9Lb7qx4
Thanks for the video, I changed the alternator and in the same time the Belts
Thanks for the help
@lespauljunky74 This video covers form 99-02. Your 98 may be similar. Usually there are only a couple of bolts holding these on.
Wow...This video was a life saver.... It took me less than 1hr.. including getting the part. Thank I will be subscribing from here on out. Thanks...
This video helped. Same exact process for my 2002 GMC Sierra 2500HD. Approximately 10 to take off and 15 to put back on.
@1aauto Thanks for your reply! I went over the problem, and it turned out that the alternator I purchased was faulty. I returned it to the Autozone (they tested it and stated that it passed)...but, I still requested a replacement. They were helpful and gave me a replacement. I installed it, and everything worked just right. Thank You.
It would probably take about 45min to service the alternator. We carry NEW alternators,with no core charge on our website with free shipping. These aren't rebuilts they're brand new units. 1aauto.com 888-844-3393

Thanks for doing these videos! I was thinking of taking it in! 500 to have the shop do it! Bite me!!!!
Thanks SO much! My first time changing an alternator was a breeze! (mostly because it's 20 F outside) I never had to take the engine cover off on my 99 Sierra.
Thanks for the video. It saved me time and money. I will be looking at your video on how to replace the tailgate handle.
You Rock Brother!!!
I watched your video. I ended up replacing the alternator to my 2002 Chevy Suburban. I saved a great amount of money doing it myself..
Thanks....
Thanks 1AAuto. You saved me time and money.

Thanks for making these videos I just replaced mine today I have a 02 silverado 1500 and I watch all your videos on how to do stuff thanks
Thanks for watching the video. Have a great weekend! 1aauto.com 866-403-3393
This video was perfect many thanks it got me back on the road in no time.
@5312gdog Thank you for checking out our RUclips auto repair videos. Have a great day!
@Sucio16 If your using the heat, or the AC and it dips.This does tend to happen on many vehicles because there is a great amount of draw on the system. If your just at an idle with nothing on such as the headlights, heat or AC and it tends to fluctuate then there may be an issue with the alternator.
Thanks for the video this is something I can do myself and save money.
it is similar but they did a change over to the Vortex engine in 1999 so it might different slightly between your model and the 1998 but the concept will be the same.
You guys have been so helpful in all of your videos. Thank you for all the time you put into making these! You guys are the best!

going to replace an alternator on my fathers 2005 chevy silverado 1500 today. This is my reference video ill let u know how it works out. Seems simple enough!
Your videos are the greatest, you've saved me 1000s of $$$
That's our goal. We're glad we could help you out. 1aauto.com 866-403-3393
There could be an issue with the battery terminals. Over time, battery terminals can rot from the inside out and oxidize. You will want to change out the cables and see if that solves your problem.
thank you very much...exactly the engine and configuration I was working with...life saver...
Thanks so much for these videos! Saved a ton of time and money I don't have!
No problem. Glad to hear it helped you out. 1aauto.com 866-403-3393
If it's the same vehicle it should be in the same spot.
Great video, I have never done this before and you guys made it easy. I check to you guys for everything I can please keep the videos coming! Thanks a lot!
nice video, helped me out alot and was very easy and streamlined to the point!
@sidneyincanada No Problem, Glad to help! Please visit 1A Auto dot com next time you need parts for your Chevy Silverado, Tahoe, GMC Sierra, Yukon, or any other car or truck.
This video was very helpful. I did run into one issue when I bought my alternator I upgraded to a more expensive one and I didn’t know I needed a bigger belt size..
+robthebank1987 Thanks for checking us out. Shop here for high quality auto parts: 1aau.to/m/Shop-1AAuto-c
thanks this video helped a lot and saved me money!
@hollowpt Thank you for the input.
You should ba able to match up the year/make/model and motor size to the alternator that you need.
Many THANKS for your videos! Just saved me $$ replacing my alternator. Cheers!!
Glad we could help. Thanks for watching 1aauto.com 866-403-3393
Yes it should be the same.
You could have someone try to start the truck while you listen to hear where the sound may be comeing from.
It will be similar on the 2005 but not exactly the same for that year.
Thank you for posting these videos. This one was very helpful!
+Steven Palmer Thank you for the feedback!
Thank you for this video this save me a lot of money
+Juan Diaz Thanks for checking us out. Shop here for high quality auto parts: 1aau.to/m/Shop-1AAuto-c
@blackandgold51 This should be the same as your 99 Yukon.
awesome video guys!! thanks!! one question though? My battery light has been on ever since i swapped my alternator but its charging fine and the volts are good, what gives?
Excellent!! thank you
I just broke down. 45 minutes later, I was on my way. Thank God for RUclips!
Thanks for the Video! It helped very much. However, just a question, hope you can help. After installing the new Alternator, my battery voltage fluctuates from 14 to 12 Amps. Wondering if you have a clue as to what is wrong. (Or, anyone who reads this, and knows, please reply.). Thanks!
You guys are awesome! Thanks for the guidance!!
thank you for this video really made it easier on me

Thanks bud! Good video
When the alternator goes bad on these GMC Sierra 2500HD does the ECM throw an engine code?
Can you tell me about how long the whole process takes? I got in my truck this morning and it said "battery not charging". I gave it some gas to send voltage and the message went away. Took it to have the battery tested and it did the exact same thing. So the guy said that my alternator either has a short somewhere or it is going out. Should I just replace the alternator?? I have a 2003 Chevy Silverado. 4.8.
how do I know which code is for the alternator on my glove box sticker? i dont have the kg8 code...i have a 1999 yukon slt 5.7L 4WD..
I have a 96' Tahoe, will this be the same basic process for replacing my alternator?
Thank you!
I put an alternator in a 2005 GMC Sierra and I still have same problem over charging what do I do wrong
Thanks.....
Hello, I have a 2001 suburban. Replaced alternator because the old one went out. The new one doesn't start charging (11.64 volts) till about ten to twenty seconds after starting the motor. then it charges at (14.87 volts) why the delay to start charging. also this only happens when it sits for several hours. Otherwise it starts charging right from the start of the motor? any comments or help would be greatly appreciated. Thank you..
Is this the same as a 2002 Chevy Tahoe Z71??
Will work on a 2005 sierra right?
Same thing on a 02 Tahoe?
but why would that happen as soon as i swap my alternator? ive never had that problem before...to attempt to fix that i unplugged my battery for 10 minutes and when i connected it my truck started then idled for like 1 second than died...did this 3 times then 4th it ran fine and have had no trouble ever since
Does this apply to a 98 Tahoe?
Thaks for the great videos you same some money
You're welcome! Thanks for watching 1aauto.com 866-403-3393
I added a high end aftermarket stereo/dvd to my 2004 Silverado 1500. Is it okay if I install the higher amp alternator? My 103 amp's regulator just failed.
+Audrey Truss You may want to make sure that the wires can handle the extra amperage. Hope this helps you out. 1aauto.com
I have an 03 Silverado, and my alternator is making a whining noise that increases when I accelerate. Would it be a good idea to replace it? I'm going on a 1500 mile trip next month and I need some advice.
You may want to have it checked to see if it's going bad. We carry a news (not rebuilts) on our website with free shipping in the lower 48 states. 1aauto.com 888-844-3393
It should be as long as it has the same motor. If you call our sales staff at 888-844-3393 they can tell you what the correct alternator for your application would be. We carry brand new alternators with no core charge for all kinds of vehicles. Hope this helps you out. 1aauto.com 888-844-3393
It should be a similar process. You may be able to apply some of the basic steps shown in this video to your application. 1aauto.com 888-844-3393
nice video
i think my alternator is going bad
but with a good charged battery, my truck wont start
isnt that strange? shouldnt it start even with a bad alternator? do i have a bad starter?
You may want to take a look at the starter if both the battery and the alternator are known to be good. 1aauto.com 888-844-3393
thanks
it was the starter
used your video. very helpful

What happens if you use a 130 amp alternator when it calls for a 105?
+Los Ojos De HotSpanish You should replace it with the recommended amperage. The vehicle's wiring may not handle the extra amps and could cause a fire.
Great video. Appreciate the list of tools needed in the beginning, and the glovebox code confirmation of what amperage alternator to get is super helpful! Extra notes: (1) There's a clip on the backside of the electrical plug connector that must be lifted before the plug can be removed. Take care not to break it by pulling without seeing/lifting it back a bit. (2) On my 2001 there were two brass(?) grommets on the forward bolt holes of the engine block (where you first slide the bolts thru). Mine were beat up but functional. See this video: ruclips.net/video/XbbVYJlxdAo/видео.html. Suggest getting a couple from the dealer if possible before doing the job. (3) The pivoting ratchet handle he uses is very helpful! I went to Harbor Freight and got one for $29 and it made the job much easier, esp working the tensioner pulley. (2001 GMC 2500HD 4wd w/ plow package, 6.0L 108k mi )
