[@shoelessone]

I just want to say, you did such an amazing job with this video. Seriously one of the better "how to" videos I've seen in a while. Thank you!

[@NielVTEC]

Really appreciate it, love helping people out!

[@Stormmaniac]

I know i am late to the party but you did a very good job on explaining in detail what needs to be done thank you!

[@jacquelineconerly9150]

You mentioned the serpentine belts!! That is soo key!!!

[@lefterisgr-uk9730]

Job done ! Thank u mate i just suggest to all that give litle time with engine was running so they can recognise the new alternator.After 15 minutes starts again my heater and my indicators. Happy ending finally.

[@derek5395]

Very nice video! I like how you recommended to clean the electrical connections! That's an important step that's often overlooked.

[@NielVTEC]

Thank you, your words are very much appreciated!

[@kyliewalker6647]

You explained it really well, I just changed my battery but think it will need alt. Im gonna try to replace it following yr tutorial, thanks heaps. Btw, You have the coolest hair/style. Very nice 👍

[@NielVTEC]

Ahahah thank you so much!

[@IR088Y]

Thanks for the tutorial I'm going to try changing the alternator to see if that's the problem

[@GarethBarnes-vs1dg]

Great video. Do you have one to replace the clutch?

[@NielVTEC]

Sadly and happily not yet, but I'm pretty sure you can find other people on KZbin who did a great job recording it!

[@mattr1414]

Just what I needed, saved a bunch of $$, thanks!

[@NielVTEC]

Glad to hear it!

[@HappiGolucky]

Hey bro, what's the torque spec for that bolt on the bottom side of the alternator?

[@NielVTEC]

There isn't much information on them. But just tight enough that the alternator won't move, but not too tight where the bolt would snap on you

[@hmsailor6133]

Good video man. How did you remove the bracket in front of the 14mm bolt?

[@Thurston-q6q]

I broke the bolt on mine. A 10 minute job turned into a nightmare. They put low grade bolts in here so be careful and if you get it out without breaking it replace it with Grade 10 bolt for the next guy. The alternator is lile 250 bucks near me so I had to drill and tap mine which was a complete pain in the ass.

[@NielVTEC]

Yeah, same thing happened to me, definitely a big flaw on these cars!

[@Max.527]

How tight should the belt be? The new alternator I put in is screeching so loud. Charges battery but it's very annoying.

[@NielVTEC]

It probably means that the belt will need to be replaced!

[@Max.527]

@@NielVTEC ok thanks!

[@jonathanmacdonald9276]

No. Belt is screeching because you have to tension the belt correctly. Screeching means it’s to loose. My 2009 yaris sedan did that a few years ago. I loosened the 2 bolts on the alternator and used a pry bar and pulled the alternator more forward a bit. Solved the problem.

[@derek5395]

A squealing belt is either cracked and worn or too loose. If your alternator is older it could also be the alternator itself.

[@jimeerey]

2:20 something to note when removing this connector. My 08 is a squeeze release. The video shows the dude easily removing it. What I did was I left it connected and when I was able to remove the alternator. The connector was very easy to remove. I fought it for so long and almost broke it. Don’t do what I did unless absolutely sure.

[@NielVTEC]

Hopefully this help other people out! Thank you so much for sharing

[@mossymeadowminecraft]

Thank you so much

[@ZenCJ]

So I replaced it and the engine is shaking/vibrating pretty decently a little bit when idling. Is the the computer learning it or whatever ?

[@NielVTEC]

If it's still doing it for a couple of days, the bolts aren't probably tighten enough!

[@mistera166]

No. Check videos in YT on how to reset idle in Toyota cars. It takes about 10 minutes. It is necessary every time you disconnect the battery and reconnect it.

[@CouchMan88]

Car runs bad after restart because the throttle body is dirty. ECU will compensate to make it run correctly but if you clean the throttle body and possibly the MAF sensor it should idle pretty good right after reconnecting the battery. I did the same job and had the same problem but cleaning the throttle body fixed it. Before it had a slight vibration under load with the A/C or a lot of electrical components turned on.

[@NielVTEC]

That makes a lot of sense! Thanks for the information, I hope this help people out👍🏼

[@niekvos2136]

Good work bro. Thank you.

[@NielVTEC]

Appreciate it and I'm glad to help!

[@violetsky3067]

Super helpful video (and comments) thank you!

[@paulbhager]

Thanks. Just what I needed. 😎👍

[@cosysolitude]

Hey! What was the size of the screw u put in the thread? I am desperately trying so hard as the old screw does not fit!

[@NielVTEC]

Do you mean bolt? I reused the same one, be careful not to snap it like I did lol

[@NinjaNerosis]

How did you get the new one on? Mine isn't fitting good at all

[@NielVTEC]

You just got to put it sideways first, then put it at the correct position once inside. If that doesn't work, make sure you have the good part first!

[@matronix1977]

I just came here for your hair, so thick and shinny !

[@sparky3094z]

Bro your hair is sick af man what do you put on it ?

[@MiiksConspiracies]

Website to buy it?

[@NielVTEC]

I bought it from Amazon, but you could also get it from your local car parts store or even from the junkyard!

[@MarcoSoto-p9u]

Y para tensar el alternador igual hay que sacar el perno que está abajo

[@nomad9000]

I think the yaris was running on 500 RPM and dying for a few times not because of the new alternator. Today I've disconnected the battery to clean the connection points and my yaris had exactly the same symptoms as your but then went fine.

[@NielVTEC]

Yeah no, I just had to run it a couple of times and the car stopped dying!

[@rodrigogar]

It happens because the computer resets the throttle body plate position once the battery is disconnected, when driven for a while the computer adjusts the position again. Or clean the throttle body plate :)

[@NnnnLlll-xn7cw]

How do you clean the wires

[@NielVTEC]

I would use a specific spray cleaner for wires if it's really bad, then I would just use a brush!

[@kittyclops]

Where did you get your alternator?

[@NielVTEC]

At my local auto parts store!

[@anglesciufarink4215]

That bottom bolt is just stuck hard for me, already kinda slipped and messed the shape of it. No idea how im going to unscrew and replace the alternator 😮

[@NielVTEC]

Torching it might be your best bet!

[@jonathanmacdonald9276]

Belt needs to be pulled further up ( towards you if your in front of the car) mine is pulled closer like way further up, that belt is too loose. Has way to much slack, needs to be tighter. You did a good job tho that was the only thing you messed up on. Also, stay oem, Toyota makes amazing cars, and the Yaris is from Japan they’re even better made in Japan compared to Hondas and Toyotas that are made in Mexico, USA, and Canada. Japanese know what they’re doing. When my oem alternator went out a few years ago on my 09 Yaris ( same as yours and also grey) I went to the dealer and spent $280 for a NM new manufactured oem denso alternator. Denso and aisin make amazing parts and are Toyotas lead suppliers. If I got 13 years out of a oem alternator made in Japan might as well spend a little more money and go oem again.

[@jonathanmacdonald9276]

I had a Bosch alternator in before I put the oem one in and the Bosch lasted 2 weeks. Battery light kept flickering. Since I put the denso from Japan In, no problems 2-3 years now trouble free. Make sure to keep that throttle body clean every 10k miles give it a wipe down, keep battery terminals clean too and keep a strong battery in that car AGM batteries are best and maintenance free and last longest. Strong battery works well with an alternator weak battery makes alternator work harder. Also if you replace the spark plugs go to autozone they sell denso TT iridium plugs $40 for 4 plugs. Best plugs out there

[@jonathanmacdonald9276]

Also change that oil every 3k miles or every 6 months whatever comes first I use Castrol 5w-30 synthetic blend oil from autozone amazing oil with a good API rating. These engines are one of Toyotas best engines ever made. Since you drive same car as me I wanna see you get a ton of life out of it bro. If you ever need assistance or have questions on anything let me know I’ve done tons of maintenance to my car I wanna get 5 more years out of this thing so hmu on these comments.

[@lanharvids]

Thank you for the help man!

[@NielVTEC]

Happy to help out!

[@geniaroberts9303]

I snap the bracket bolt putting the bracket on worse day ever

[@NielVTEC]

Yeah, this bolt has been a lot of people's worst day. But hang in there, if I can go though it, you'll surely do the same!

[@Pockstriker]

Just did this last night and my new alternator is only putting out 12.3 volts(which I know means it isn't providing any current to the battery). I disconnected the battery before starting. Any ideas what could have went wrong?

[@jonathanmason2569]

might be a faulty regulator

[@jacquelineconerly9150]

And doing the job yourself saved you hundreds.

[@NielVTEC]

Definitely! And you'll feel accomplished after the job

[@MMR20]

lol I snapped that exact same bolt😂

[@NielVTEC]

Please start🤞🥹
