Great video! I have to do my alternator tomorrow--first time trying it, and this video is really clear and straightforward. Thanks for helping de-mystify auto repair!
Thanks man! I just replaced the alternator in my 98 Camry and it is working great! I've never done more than replace a battery in my car so I feel rather pleased with myself :P Thanks again!
This is the 1st video I've watched where I think I might actually be able to fix something myself on my car finally!! Thank u for making it simple to understand!!
Thank you so much man, I got a Camry 1999 too, and the alternator died on me in the middle of the road. I found your video and I saved a lot of money on labor just replacing it myself.
Juenes Carter np, gl with the repair. Make sure its your alternator first and not your battery. Check out my video on how to test your battery before attempting to replace your alternator. Just do a search in my channel.
Thank you for pointing to each fastener. I am deaf and can't follow most videos, but you made this very easy. I have a question: If you watch your video to the point that you can see inside the 3 pin oval connection, there is white corrosion inside the connector on your alternator connector. I pulled mine off today and it looked the same - like corroded battery residue in the connector. What causes this and is it a problem? My alternator gets weak once it warms up. I thought maybe this connection was the problem once I saw the corrosion, but I cleaned it, plugged it back in and still had the same problem. Is it possible that this is the problem even after being cleaned? I noticed this connector is sold on ebay - and a lot of them are sold. Makes me wonder if they are no good once they get that corrosion in them. Can you speak to that? Thanks again!
The power from your alternator comes out from the cable I take off at 1:13, make sure you remove that and clean it if there is any corrosion! I dont remember the white residue but it could have been dried up electrical grease they put on there from the factory. If your alternator is weak when the car wamrs up make sure the belt has enough tension and there is no play in the alternator pulley, but for a much more thorough testing procedure check out my videos on "How to test a car battery" and "How to test an alternator using a multimeter". If you visit my channel and sort the videos by date they are towards the most recent video's I've made. Hope that helped, thanks for watching and GL.
RatchetsAnd Wrenches Hi - I was talking about the connector showing at 2 minutes, 7 seconds. It could be white grease. Mine was dry like the white corrosive powder seen on battery terminals. I didn't see any de-laminating of the connector pins though. I did clean them up. I will get some white grease and put a little in there to help the seal. The belt is quite snug - no more than a quarter inch deflection at the mid point of the longest run between components and the belt was replaced with a new one about six months ago when the timing belt was changed. The battery is a week old and I had this problem before I replaced it. I have no mystery power drains - so that kind of leaves the alternator as the problem. It's the original part - 14 years of use and over 100k miles. Many newer car alternators don't make it half that far.
1drhnsd1 100k isnt that much for these toyota alternators, I know the connector you were talking about but the one that will effect the power supply is the one at 1:13. That one is a lot more important to clean up. Cheers
RatchetsAnd Wrenches I know the one you're talking about - it comes out of the rectifier where the voltage is output from the alternator - and is on the top rear section of the installed alternator. That connection is very tight and is clean. - but thanks for the advice. If I wanted to replace the entire regulator and rectifier assemblies, where could I find them cheaper than the dealer? I tried the typical auto parts stores - they don't sell these parts. I'm in San Diego, CA. (where it just rained finally after a year!)
1drhnsd1 If napa or autozone dont carry them, you'll have to buy them from Ebay. I am not sure which part you are planning to replace though? Are you talking about the alternator? on this car the regulator comes inside the alternator! also give me your make and model, I'll see if I can find you the part.
I appreciate all your help and advice. My car is a 1999 Toyota Camry with a 2.2L engine. It looks exactly the same as the engine in your video. The alternator is the original one. Inside the alternator back cover, there is a regulator and the 3 pin oval connector is part of it. I want that part. Next to the regulator, is a rectifier. That has the diodes in it and one end of it is threaded, goes through the back cover of the alternator and connects to the battery via a single large gauge wire with an eyelet on it. I want that entire rectifier unit. I also want new brushes with the holder. For all of these, I want only new parts. Toshiba sells them, but they cost more than an entire alternator from them. On ebay, I found a regulator and brushes (from China), but I couldn't find the correct rectifier there. I was hoping to find one company that sells a rebuild kit that included all these parts. Shops that redo alternator need all of these parts at one point or another - so someone sells them - I just don't know who. The rectifier and regulator both have electronic parts in them and all electronic parts will eventually fail from the hot/cold/hot cycles of a car (I think I said this already). Some parts outlast others, but none are forever. I want to replace all these parts instead of one now and one later and another. I've read stories about where a person buys a rebuilt alternator only to have it fail a year or so later. I think this happens because the alternator was repaired - leaving some of those old electronics in place that have already been through thousands of temp cycles. Thanks again - I really appreciate your time and help.
hey great video. how ever do these car alternators have built-in regulator or an external one? also , the 3 wire coming from the alternator what are they for?
Dude, awesome video bro. Very helpful. You make it seem simple. My alternator went out this morning on the same vehicle. A 99 Toyota Camry. Same engine too. So I'm buying a replacement alternator this afternoon and installing it myself. Thanks to you I now have the knowledge. I will be sure to follow your channel for any future tips I may need.
Thanks so much for the video it is so helpful and clearly explained. I ordered a replacement bosch alternator for my 1999 4cyl toyota camry fitted with a bosch alternator and the alternator is identical apart from the small wire connected to the d+ terminal on the original alternator is connected to the b+ on the new one. Is this a problem? Am I right in thinking d+ is for the warning light? Cheers
Not too car savvy so i apologize if this is not correct or is a dumb question, but is the "dry belt" that the timing belt? and if so wouldnt just dropping it like you did at 3:23 mess with the timing or something? if so, how would you recommend the best way to replace the alternator without losing the timing? or is there another video you'd recommend for that?
I changed the alternator on my200 Camry but in the process my pigtail plug was very dry and brittle it broke I still manage to plug it in and the battery light is still on
my car wont start after putting in the new alternator but i just bought the battery from auto zone a few months ago, anything else on the car i should check?
Great job. I am glad people like you are saving other people tons of money by showing us how to do these things ourselves.
10 years later and you're still saving people money, thanks
Great video! I have to do my alternator tomorrow--first time trying it, and this video is really clear and straightforward. Thanks for helping de-mystify auto repair!
Howd it go
Thanks man! I just replaced the alternator in my 98 Camry and it is working great! I've never done more than replace a battery in my car so I feel rather pleased with myself :P
Thanks again!
Np, glad to hear you got it working good. cheers
Thank you so much. Changed my girlfriend’s alternator in 30 mins, never done one previously. So straightforward and simple instructions
This is the 1st video I've watched where I think I might actually be able to fix something myself on my car finally!! Thank u for making it simple to understand!!

Ramon Zavero Awesome, people saving money watching my video's is music to my ears. cheers
Ramon Zavero yeah for me too my car is the same thanks for your time doing this video
ty for your comment, cheers.
ty for your comment.
This video is super useful. Making a video on the complete installation would be even better. Thank you for being part YTU.
Saved my freezing fingers! This was really helpful and saved me from spending more time than needed working on my car in 8 degree weather. Thanks!
Dam thats cold, very glad it was helpful to you!
I'm a chick. and my alternator on my 1999 camry is going bad. if I can do it myself im sure gonna give it a try. Great video.
Juenes Carter np, gl with the repair. Make sure its your alternator first and not your battery. Check out my video on how to test your battery before attempting to replace your alternator. Just do a search in my channel.
I'm part of the choir here. Great video on this job.

hey great video. how ever do these car alternators have built-in regulator or an external one? also , the 3 wire coming from the alternator what are they for?
Since I'm going to replace my alternator do you think is good for me to replace that that belt iI think its called the driving belt?
Dude, awesome video bro. Very helpful. You make it seem simple. My alternator went out this morning on the same vehicle. A 99 Toyota Camry. Same engine too. So I'm buying a replacement alternator this afternoon and installing it myself. Thanks to you I now have the knowledge. I will be sure to follow your channel for any future tips I may need.
How many miles on yours?
Excellent video my friend!!
Thanks so much for the video it is so helpful and clearly explained.

if so, how would you recommend the best way to replace the alternator without losing the timing? or is there another video you'd recommend for that?
Thats the drive belt. There is no timing aspect to it. The timing belt is in a plastic cover connected to the engine.
Thanks for the video, very informative.
Great video. Thank you 👍🏻
Fantastic Video and very helpful! - Thank you my friend!
