- So your alternator has gone bad on your Toyota Tundra well this video will guide you on replacing it.
Tools needed :
Ratchet
Flat head screw driver or 8mm nut driver
10mm socket
12mm socket
14mm socket
There’s an easier way I found today while doing this. Pull the nut and bolt for the power steering pump so it can slide forward on the bolt. Then go below and on the bottom of the radiator fan shroud, look on either side there is a clip, pop both, and push up and voila the fan shroud is no longer in your way, and you can take the alternator down from the bottom, it makes disconnecting the wires easier cuz you can turn it while it’s still attached and get pliers on the wire, and nut, then twist it as you pull down between the hoses there. Goes right back in the same way, took me less than 15 minutes to get my new one back in and hooked back up once I figured this out. Hope this helps. Nice video, thanks for sharing your work.
Just did mine, took 1.5 hours, 2 things I would recommend, take the alt out from the side, just pop the tab that holds the little mud flapper and it comes right out, just turn the wheel to the right when you park it,,,and a trick I used to stab the alt onto the bolts, tie some twin around the pulley, you can hold the weight up with one hand and guide it in with the other, there is nor room for 2 hands down there,,,,,FYI I did this and I am missing my right arm,,,,so man up and get it done,,,,
I just wanted to say thank you. I replaced my alternator and serpentine belt on my 2007 Toyota Tundra with this video as a guide. I appreciate you making it.
I have an 07' and wasn't sure if his was a first or second gen so I appreciate you writing this comment.
Good video. But for anyone looking to do this. Loosen the power steering pump to mostly off, enough to slide forward. Get under the truck, undo the sway bar, reach up remove the 2 bolts and nut off the alternator. You have wide open access underneath without having to remove a bunch of other stuff but you'll need an impact for the sway bar.
Great video. Thanks for putting it together. One item of note, my PS pump had two different length bolts. Not sure if it matters but I definitely kept track of what went where. This is the first work I’ve done on a truck not manufactured in the 1970’s. Damn they cram everything in there.
So...1970s older cars were easier to fix, more spaced apart?
--never knew older mechanics had it easier...XD
I know it😅
Video was helpful. Did this job for a friend this morning. Tedious, not impossible. Whoever designed the power steering pump to have to be unbolted and moved before you can remove the alternator needs to be drop kicked in the nuts. Don't wrestle around with trying to pull the alternator our of the top. Unbolt the sway bar and drop it out the bottom. It's a lot easier and you have more room to work.
Thank you!! Helped my brother change his alternator just now... he called me asking for help and I just pointed him to this video and some written instructions from the forum.
This was a great deal of help, I probably wouldn't have gotten this done in the same day by myself without this video
Wow so proud
sweet, GOOD VIDEO MAN,THANKYOU!
IM INTO CAR AUDIO ,LOOKING TO REPLACING MY ALTANATOR ON MY 4.7 FIRST GEN. TUNDRA WITH A H/O ALT
THIS GAVE ME A BETTER UNDERSTANDING OF MY CHALLENGE'S ,SO THANKYOU!
I wish I filmed the headers I put on my first gen, took me 3 days on & off & still did it faster than the shops I called,books times!(their chart) the passenger bank was alot easier ,the driver side/bank had me going bald at 26. & I got em headers all on ,(obx racing) they look sweet & sound alot like a exotic ford cobra engine!
DIY is always the way to go, I just RUclips something before I do it, even if I've done it already!
SAVED ME $1,400 ON JUST MY HEADER INSTALL!
IT HELPED A LOT. THANK YOU. ALL THOUGH I TOOK THE ALT. OUT BETWEEN THE RIGHT INNER FENDER COVER AND FRAME. I DID IT IN THE FIELD LITTERALY. IF I WAS IN MY SHOP I WOULD HAVE SPUN THE SWAY BAR ANCHORS OUT AND DROPPED IT OUT THE BOTTOM. NO TOP STUFF. THANK YOU VERY MUCH. IT GAVE ME A GOOD IDEA.
Pulled mine out from the bottom. Jacked up the truck, let the tires hang.
Removed shield.
Rubber mat by wheel
Left wheel on
Serpentine Belt removal
3 alternator bolts. 130 A have towing package
Did not need to remove hoses or power steering pump. Power steering pump had 2 bolts and 1 nut on the front by the pully. Wasn’t necessary to remove.
Pulled out from the bottom from where I removed the rubber mat.
My brother I took it out through the bottom, it was very easy.
Thanks for the video. Ez to take it out from the bottom, just remove two of little bolt to hold the hose. You will see that hose at 1:23-1:25.
Thanks for the video. Helped me tackle the alternator on my 2011.
You Rock Cody! Thank you for taking the time to show us the process.
That looks pretty easy I can handle that how much are they and what's the best place to get one
thanks for your video, I'll be using this video to change my alternator tomorrow!
Did you mention disconnecting the battery terminal before starting the job?
Okay on the 2008 Tundra with the 4.7 everything in the video is pretty close until you are ready to remove the alternator. Instead of going out the top, go under the Tundra and drop the stabilizer across the front, the alternator just basically falls out. Fish the new one right back in thru the bottom. Start the alternator bolt and nuts. Put the power steering pump back in. All of this is in the video. Now the power steering pump has 2 bolts and 1 nut. All can be reached thru the holes in the power steering pulley. 1 is kinda hard to see but its below and to the left a hair of the top bolt.Get it thru the pulley.
mine came out from the side no issues, saved time having to R&R the stabilizer bar
Truck is low on coolant in overflow reservoir. Always use a nutdriver to tighten hose clamps . Screwdriver is just in a pinch
Did I see it correctly, did you have to pull the power steering pump to remove the alternator from the engine bay?
I didn't have to remove the power steering pump, like I said, the alternator was easier through the bottom.
Try it.
How
Mustve done it on a 2wd and not 4x4 😂
Watched the video cause a co worker needed an alternator but after finishing it's impossible to pull up top just remove the skid plate and the power steering pump then pull the one tranny hose at the bottom of the radiator and it slide right out 1.5 hour job and I'm like a 4 of out 10 mechanic
Toyota put one on for me, it lasted 13 months, I had it rebuilt for $50.
My 5.7 cannot use most of this info. can you do a 5.7, as it has A LOT LESS space due to hoses and steel lines.
I have a problem. Where does the longer bolt go? I didn't pay attention that one was longer than the other 2. Are the power steering bolts equal length?
Probably the same engineer who designed the starter on an 07, 5.7. Took me a month to change mine….. 4 hours of actual work, 30.5 days of cussing!
Thank you I just wish Toyota didn’t like to bury their alternators
What was the size (power) of the original alternator? Did you replace it with OE? Or upgrade to a larger one?
Please respond but the 14mm bolt on the alternator broke is the mount the alternator is bolted to able to be taken off?
How much labor should i expect to pay for a mechanic to do this?
Approx. 350-450
Not so easy with the 5.7. Little less room in the engine Bay.
Thanks for the video, would have helped to show how to reroute the serpentine belt to reinstall, rather than just saying you got it back on. Much easier to go in from the bottom.
Google it what i always do then screenshot it
where did you get that large rachet?
Man this really helped!!! Thank you!!!!
The mounting dowel pins that go behind the unit are rusted into the alternator. I went to the dealership and they said that they don't exist...??? I need to replace them on my new alternator. Anyone have a part number? 2007 5.7 Tundra. Thanks!!!
This is the same access method for a 2005 Toyota 4runner v8 sport 4.7 liter engine generation 4. thanks!

Same procedure for installing a high voltage alternator
Wait until you have to do the timing belt, man oh man FUN
total time spent?
Thank you 🙏!!!
take air box out and then remove power pump and then remove alternator Took about a 1 Hr to replace
Great video . Thank YOU!
Thanks
It’s a lot easier putting in and out from the bottom
What Brand alternator did you go with and have you had any issues with is since install? Thanks
+Joel Thomas went with advance auto brand and havnt had an issue since i installed it.
Joel Thomas
How many miles did it have when it went?
they don't if there denso
the one I have I have no clue if it's been replaced. but I bang 2,000watts rms all day long and it's been fine had 8 different system's in it it's never gave me a issue ,nothing last forever & I'm looking to get a mechman or GP
my alternator just went out.... 07 78k miles
not even close to the 5.7
it came out from the bottom for me!
Not the 5.7 I’m trying myself
Definitely not for a 2012 5.7
Best thing to do is junk the truck!
Such an awful design can't even believe they put this in that location. Alternator should be up on the very top totally accessible also oil filters
Very convaluted video. Nothing is in proper sequence order.
Your camera works sucks.
