How to replace alternator on a 2012 - 2020 Chevy Impala with 3.6L V6 (2024)

Thanks for saving a hard working family hundreds of dollars! You are the man. I appreciate you making this video!

THE BEST HOW TO VIDEO IVE EVER SEEN ESPECIALLY AT NIGHT.

Thanks for the video. I struggled with the serpentine belt and was unable to find the diagram for it. I would strongly recommend taking a picture of the belt before loosening it.

This video deserves the likes as much as the views, pretty much dead on, same scenario for me, got home from working all day, bam! Alternator goes out, picked one up put it on, and can go to bed early like nothing happened❤

Wow I was about to pay a mechanic $850 to do this! Good thing I found this vid, thanks you saved me hundreds.

This really helped a lot because I was struggling with putting the serpentine belt back on 😊

Thank you so much, I had to change mine myself , mechanics wanted over $450 , I said hell no. Great Intel, had mine done in 1 hour , only cause I took my time.

Thank you very much the video was very very good better than 90% of the videos out and even done at night

Best “how to” video every...no bullsh*t 👍🏾

Bro I think you just saved me some money. I'm upgrading my alternator for my audio system and this vid tutorial is awesome

I hope you are in a classroom somewhere teaching kids who Just don't get it. Great Job. 👍👍👍

Hey that's pretty interesting you're real clear how you explain everything I'm 73 years old I used to do Automotive work when I was younger at a gas station for around 4 years and this is really going to help me a lot when I get get my new alternator how I can take the old one out and put my new one in my 2015 Chevy Impala with a 6 cylinder hey guy thanks a million I do appreciate it

This made replacing my alternator quick and nearly painless haha. Thank you!

For me it was a lil hard putting the band back on but thank you your a life saver bro

This instructional video was spot on. Made my alternator replacement a breeze. As an aside, I installed a new battery when replacing the blown alternator, which allowed the removal of the alternator under the upper heater hose and thru the battery box. Saved me $450

This is the Video I'm gonna use tomorrow on my 2015.. Much Respect on doing it at night!! I'm sure I'll be doing some, if not all of mine at night.. As I was just outside for the last 4.5 hours (9pm-1:30am) Walmart trip for a jump box, swapping Batteries twice and changing terminals.. Very Unsuccessful night..I'll let ya know how I make out, thanks in advance.

Great tutorial. Super detailed yet concise. Everything was explained very well. I am also happy to know I'm not the only one who struggles getting stuff in and out of those tiny spaces. Taking the battery off on this car requires removing like 2 or 3 other components, too and EVERYTHING is a super tight fit.

Excellent video. Thanks. You didn't waste time with needless chatter. Beats some of the other videos I viewed. 👍

Right down to business. I like it. If I may make one suggestion though. Give the fastener sizes a shout out to make it easy peasy on what tools someone doing it out and about would need to carry. That aside, thanks for the video, helped a ford guy real quick figure out what he got himself into helping a friend of a friend ;) Thank you.

Awesome video straight to the point and no BS! Thanks for the tips and what sockets MM used, saved the guessing game! 👍

Change my first alternator

Just plain awesome! Quite a nice saving this concise, to the point, non rambly video provided. Over 500 bucks saved after sourcing out parts and doing this myself. To have done this in the dead of night is pretty impressive too. Cheers!

Your patience is exceptional.

WOW!! Awesome video!! I appreciate this so much! Thank you, great step by step instructions. Keep up the good work.

Excellent video, great explanation. You made that look like a child could do it

Thanks bro! You just saved me lol, couldn’t remember if the pulley was the third bolt or not. Was standing there with a stupid look on my face trying to figure it out lol.

Excellent work AutoRex; thank you for the share...♥ Charles from Mesa, AZ

Thanks so much for this video! Going to give this a shot myself, nice work!

A warning to those with the beefy boy 170 amp alternators. It is notably wider than the standard 150 amp. To save you some heartache, take the idler pulley loose bolt loose from the block but don't remove it fully. undo the other bolts to get the alternator free, then reposition it. The pulley will move with the alternator. You can take the pulley out then.
Second to pull the things out, wiggle it past the center toward the exhaust manifold, you'll have more room to get it out there.
Alternatively pull the battery and upper coolant hose for an easier extraction

This guy is the Best!!! So clean and precise. Man thanks 👍. Best video. You should be in the classroom!.

was thinking i was going to have to take off the motor mounts to do this, thank you!!

when this dude grew a third arm I started losing my sh*t

Best tutorial ever

I did the same thing step by step and it still say service battery charging system. And i replaced the battery at the same time

Hey man, great tutorial! My 13 impala just had the check battery charging system light come on and my alternator is intermittently working according to the multimeter. I changed the shunt on the negative terminal and still no luck. Looks like ill be pulling this alternator. With your video im not worried at all. Thanks!

The 1st 10 seconds I was scared but the comments in here are great so I'm gonna see where we go. I'm only scared cuz it's dark outside lol

Looks easy but I may pull out my battery so I have more space to work with but we’ll see, I wanna get a higher amp for my car. I’ll also need to change the upper mount and check my belt too. Nice video

THANK YOU SO MUCH! I've never done this and your video is perfect

No lie u save me $200 👌🏿👌🏿👌🏿👌🏿

Great video, helped us replace our daughters alternator. Thank you!

Man for doing this at night very good job and great video. If you can do it at night I can do it during the day haha thanks again man!

Thank you so much best dyi mechanic video yet

Great video, thank you. Mine just went out 2 weeks after I replaced the battery.

I hope this works for me tomorrow. Tried it today but couldn't get the belt off. Also dropped the small bolt for the mount. Hope it's not vital

If you remove the positive terminal and pull the harness out of the way then you don't have to remove the mount. Alternator slides right out.

Rex is the sh*t!

This was a very helpful video! Thank you!

Good sh*t man, thanks for the video! I definitely feel better about tackling mine now!

Great how to video, direct precise not a lot of wasted time.

Thanks I'm goinylt to try this tomorrow. Your video makes it look simple. I'm not mechanically inclined but I'll go step by step with this video. How long does it take or should it take?

Do you think I can drop in the optional GM 170 amp alternator vs the standard 150 amp without running into any issues? Believe the 170 is for the optional police package but I’m running car audio stuff so need to upgrade it.

Very good video excellent in the dark man great video!!!

Great video ,
I decided to like and comment and subscribe 🎉🎉

Good job, but why you choosed night time to do this?!

We're you getting a "service charging system" message before swapping out the alternator?

thanks i just bought a 350 amp alt and as wondering best way to change it on the lfx engine.

شكرا ياصديقي

Do yo happen to have the diagram of the serpentine belt; can’t seem to find it for 2013 impala

This vid probs set the business shops back well over million $ in labour and there commision on parts accoss the world,lol

Awesome video. Thank you sir!

Whatever reason my bolt under my boot wasn't a 13 it was a 12, not the first time one of my bolts has been the wrong size

This is for a 2020 aswell?

That style changes after 2013, 2006 to 2012 will look like that.

better than the other guy, dont foret to wear gloves

What camera set up😮

Do you know about the 2019 Chevy impala?

my pulley bolt isn’t going in after putting new one in i took out the new and put the old on to see if it was different sizes and the old one did the same thing

Put the alternator on and it still says check charging system..... any ideas on what this could be?? Thanks

This is for the Limited right?

This video is excellent please make a video about replacing secondary air injection check valve on 2012 Chevy Impala please don't stop making these videos thank you your great!!

🙏🏿🙏🏿🙌🏿🙌🏿

i seen people do this in the day time and was still confused here he is doing it at night with a silent partner

I need to replace the serpentine belt on a 2014 Impala limited LTZ, it looks like a tight area behind the tensioner pulley as if the belt will have to be turned sideways to slide up behind then over the tensioner pulley...I have seen some belt routing and it is different for the Impala Limited then it is for plain Impala both have the 3.6 engine...any advise on this before I get started replacing the belt? Thanks.

Nice 👍🏽👍🏽👍🏽 thanks

How come you removed the one of the pulleys?

Pull the battery ten times the room

You rule .
But ill let my mech. Do it a little too much for me .!😊

Filming at night, why!?

If you like this video don't watch the video where they remove and replace the AC compressor on a 2013 3.6 😂😂😂

wonderful exacting descriptions well done
