Great video Roy, thank you for well and easy explanation. God bless!

[@Crusty_Otter]

Thanks for the great video, it's the best one I've seen for this fix. Most guys don't cover little things like: pressing the tab on the electrical connector, using dielectric grease, judging belt tension, etc.. It's really important to know what type of connector you're working with when it's hard to see.

Aloha. I was just trying to figure out how to remove the cables connected to the alternator without damaging anything since I am replacing the various battery cables. Your video covered part of that and reduced the stress of the job. Thanks!

[@smrtnz5995]

Awesome a Local boy from Hawaii, as a Former kamaaina it’s nice to hear. My alternator has got the dreaded pig squeal. I’m gonna be tackling this alt replacement among many other maintenance and repairs on my ToTaco so trying to get the benefit of your expertise. Mahalo

i have a 1997 tacoma, and its just about the same steps, but upside-down. helped a lot in the places i got stuck on myself

[@angeloubarcelo8969]

Thank you for the info, I just replaced an autozone one with a lifetime warranty for the second time in two years yesterday. Gonna get a denso one and use the autozone one as a back up…

[@RoysGarage808]

With Toyota’s, always Denso. They manufacture for Toyota’s, so buying a Denso is like buying the exact same original part. Thanks for watching 🤙🏽🤙🏽🤙🏽

My little 1998 Toyota Tacoma had the belt tensioner bracket on top of the alternator and it was somewhat easy to take off weasling it down below and replacing it from inserting a new one again from underneath. It's a 2.4 L so maybe a different T tacoma than videoed here.

[@antinodellacioppa7525]

I will be replacing the alternator this weekend on my 2000 Toyota Tacoma,I must have watched your video at least 12 times.

I started pulling out the alternator in my 95 Tacoma by pulling out the top bolt and the bottom nut but it wasn't coming loose so I had to give up for the night so I could look this one up. I found and watch your video and saw that you had loosened and removed the adjusting bolt in back. I did not see or know of the adjusting bolt. Thank you for your video.
I just got the new alternator in but had trouble with the plug clip. You said to push the tab in then remove the plug. It seems my plug clip is ass backwards. The clip broke off but found that I had to pull the clip out instead of pushing the clip in. I had to pull (or pry with a small flat blade screwdriver) on what was left of the clip.
Here is a question... been having a problem with the 10A fuse in the left side dash fuse box which seems to blow when I put it in reverse but just noticed that when I was testing the voltage of the battery and alternator( with truck off and engine running ), I only had 12 volts engine off AND engine running until I put a new 10A fuse in. As soon as I put a new 10A fuse in I noticed a decrease in engine idle. When I tested the battery voltage again I had 14.5. Does this seem common knowledge for a blown 10A fuse to prevent the alternator from charging ?

[@OzarkPilot]

I agree,

[@madisondrumz]

I'm assuming the VOLTAGE REGULATOR is part of the original alternator and comes as part of the new one?

Thank you for this video, my alternator died on me on the way home today in negative temperatures and I had no idea what to do to get it out, but with this video i'll be set to take it on tomorrow and get 'er up and running again. Much appreciated!

Its funny, those "Pinch clips" always morph into "Busted clips" whenever I work on my vehicle.

Great video! Just replaced mine in about an hour. Thanks a bunch for the detailed instructions and getting straight to the point.

[@hscic2647]

Good video Roy. Is the replacement on the 1998 same for all Gen1 Tacomas (1995-2004) with 3.4L? Also where does that "L" shape adjustment bolt attach to under the alternator? Thanks

[@RoysGarage808]

Sorry for the late reply. I would like to say that it applies to all gen1 Tacoma’s because that’s usually the case but I’m not 100% sure unless I see the car myself as I’ve seen some (very little) variations before on other vehicles (like where the oil filter is and what not). As for the “L” shape bolt, it’s hard to see in the videos and to describe but the best I can tell you is that one side will bolt into the engine and the other to the bottom of the alternator. I hope that answers your questions. Thanks for watching 🤙🏽🤙🏽🤙🏽

On the bracket there is a cut out where the adjustment bolt sits in .I just did mine and it save me $532 from a shop.

i'm having trouble loosening the top alternator bolt. it's so tight not even a breaker bar can loosen it. any advice on how to loosen it?

[@RoysGarage808]

I used a 1/2in pipe and inserted my wrench and had to put a lot of force into it, similar to a break bar. Try the pipe idea, hopefully it’ll work. Let me know how it goes, and thanks for watching 🤙🏽🤙🏽🤙🏽

[@madisondrumz]

Thanks, I have a '97 taco w 3.4v6. I sense the alternator has finally gone, at a minimum dead battery and battery idiot lite has been on. Thanks for the thorough info here!

[@carloso5102]

Hi Roy, great tutorial. Mine is charging fine but it appears the bearing is ready to go. I can not find a denso alternator that is not a rebuilt. What do you think of one made by Bosch?

[@Gabriel-lo7jm]

It's such a bad design to have the oil intake right over the alternator. Oil has killed two of mine

[@madisondrumz]

Thanks, I have a '97 taco and your video was the most helpful. Successful!
