I did this on a 2000 2500, but the speedometer stays at zero till you go a little faster, then it jumps to 27, and then to 42, and then to 64, depending on whatever speed bracket youre in. Do you have any clue what this means/how to fix it? I looked it up and dash issues are common, but no one has the exact problem and Im not sure how to reset it. Some guy jumped it with some expensive pack in a parking lot and all the gages freaked out after that, but apparently thats common with a bad alternator. Now all the gages work except the speedo? Any input would be helpful, thanks!

Wow. This was exactly what I needed. I have never installed an alternator before and got this one done in 25 minutes. I wouldn’t have known the nuance of getting the old one out but the pry bar was the right tool. Thanks.

Mine just went out today. Your video was spot on and got it fixed within 30mins. The belt came off accidentally too. Overall a simple job

Excellent video. Was hesitant on whether I would be able to do this myself, but your video shows how easy it is.

This is a great video. He gets to the point, he shows each step, FF through the right parts. You should show other people how to do a good DIY video. Thanks man, this was great. So good a female has no problem doing it.👏👏👍😉

My sister needs a new one, and this is going to help. Thank you

Good job on the video exactly what I needed to get the job done on my Silverado.

Awesome! Need to replace alternator on my truck and your video is by far the best I’ve seen so far. Thanks!

Excellent video! You showed each step clearly and at a good pace so it was easy to follow! Thank you so much!!

First time ever changing anything on my truck myself and this video helped out a lot, straight to the point. I appreciate you bro 🙏

Thank You, I followed your video and changed it out myself (in the rain ). I owe you a cup of coffee.

Just replaced my alternator wanted to say thank you for your video it was made very well and to the point. Thank you very much

Just done this myself today, wanted to say thanks for the video. Was pretty straight forward however I ended up having to replace my serpentine belt.

I barely comment on videos but this absolutely the best... Easy to follow. You get straight to the point. No gimmicks. Get it up brother!

Thank you for this video. I’ve never changed out an alternator in my life until now. Your steps were very easy to follow. My truck would not start when I finished but I found out that my brand new battery had a bad cell. I swapped it out for another battery and she started right up. I checked the voltages and everything was good. Your video saved me a little money. Thank you so much.

Thank you for this video! Great clear directions and no fluff. That’s the quickest I’ve ever replaced one!

Best video I've seen on replacing this alternator.

This was amazingly helpful and well documented! You are the man! Thank you for demonstrating this process. Made it go so smoothly.

Silly me blew my phone to get the dust and leaves out before your alternator swap. You make it seem effortless! I'll be attempting today, thanks for the sweet advice Max!!

My truck alternator just went out man thank you for this video it helped me so much.

I'm doing this on my 05 Sierra tomorrow morning. Thanks for relieving my worries!

Good video..... remember 12v battery could not shock you😎

Excellent video Thank You , this is one of the better do it yourself youtube videos. You should put out a few more .Again Thanks save me some money during these hard times .

Thanks for the video I just change my alternator on my truck i saved a few bucks 👍👍

Tip to the tip - (2004 Silverado 5.3) Use a socket, almost the length of the bolt spacing, and simply use a pry bar/large flat screwdriver to push the shim/bushing towards the front (using leverage from the back/larger side). Takes about 5 seconds instead of doing all the other stuff. Also, no real need to remove the serpentine belt and just take it off the alternator pully and let it suspend out of the way. In addition, you can get away with only removing the throttle body side of the air intake tube (if you even need to). Simply flex it back out of the way. Everything else looked good but be sure not to get crazy on over tightening the stud on back of alternator. I have seen these broken off with too much force.

Cool! I can save the widow next door a few bucks. Mechanical skills are adequate, I just don't like working on cars, but this looks pretty easy. Tip for the mechanic. I doubt you could feel the current 12V can push through your skin. If you don't like sparks, there is a trick using a credit card that will minimize the archy sparky. Hold the cable in place against the batt terminal with a cc (a card without a chip might be in order) sandwiched in between. While keeping the cable firmly in place with one hand, slide the card out from between the two. Now insert and tighten the terminal bolt. Takes a bit if dexterity but it's not difficult.

Clear and concise. Nice job. My alternator boiled off some of my battery electrolyte. Found it was putting out 14.2volts. I don’t have a manual for the truck (2005 GMC Sierra 5.3), but I think the voltage should be between 12.0 and 12.5.

Thanks man 👍 big help to double check when I'm doing it on my own. 💰 saved

Great video the only tip I could give that would help, those little washers that go with the long bolts that hold the alternator on. Take your hammer lightly tap on them to the left towards the front of the engine and they will loosen up space for the alternator to fit in easily. You can get your alternator on there without pushing or hitting with a hammer like some people do. But great video.

Good and clear explanation, thank you so much!!! What is the correct tension of the belt? Should I replace the belt as well?

Thanks sir. This video is very useful for me

Awesome video! Going to use it to help me change mine out in my 06

Thank you for the video.. well done and easy to follow. Really helped me with my repair

Thanks Max for doing this

It’s always good practice to charge battery before putting on new alternator

Thanks your video helped out a lot...

Perfect you dont do all the extra talking and simple

Well done video and instructions! Thanks

Hey Max thank you for the video .it did helped me out to remove and replace it on my 2006 Chevy Silverado. I owe you a tequila shot. No I think I owed you the entire tequila bottle of Don Julio or Patron , thank you so much. God bless you and your family!

Thx. That helped out a lot.

Thanks man

That helped alot thanks

what if the negative terminal nut/bolt is rounded off and you can only disconnect the positive terminal? will get shocked then?

My alternator is making a buzzing noise. Would getting a whole new alternator fix that or is it something else I should be looking for?

There are TWO different alternators for this series of truck that differ in amperage.... The easy key is matching up the location of alternator sensor. One attaches to the side and, as illustrated in the video, the other attaches to the rear.... You would the compression of the bolts would make it as easy to slide the new unit in but, it is always a struggle to get the piece past the forward bolt shims. NEVER beat on the New Alternator to set the piece. You may have to use a block of wood as a dead blow anvil or, the butt end of a rubber end of a fiberglass hammer to set the piece to line up with the bolt holes.....

Thanks brotha

Awesome vid I only had to watch the first 2 mins and knew what was happening for the rest!

Thanks mate.

My battery on my 05 Chevy Silverado is not charging how do I know if the alternator is bad?

very good video

You the man!

Hahaha...that's always a good sound....at least the valve covers weren't off

Thank you.

Awesome! Thank you!!!!!

So what does your dash volt meter read? Running voltage?

Where did you buy your new alternator?

I'm stuck please HELP... What amp is that alternator...do u know?

will a bad alternator drain the battery? or have a parasitic draw when checking volt meter? my truck died after about 3 days of not driving it. before i drove it daily and it would start right up.. not sure.

I took mine out and went I went to get new one they ask me is it 160 amp or 140 amp? I don’t know

Does anyone’s alternator make like a whine noise or is it just me? Cuz mine is making like a whine noise i don’t know if that’s normal though

My voltage is fluctuating from 12 to 15.9. Is it more than likely the alternator? Just installed a optima red top.

do you know what voltage the alternator was?

Perfect!,

Whats the part model?

How to choose the right alternator ?

Hey buddy how did you know your alternator went out ??

You do realize it a 12v battery, right? you're not going to get shocked, lmao

Won't shock you

You lost me at 10 mm
