Alternator Replacement - Toyota & Lexus V6

[@markvette2307]

Extremely well done I really like how you edited it but yet kept everything pertinent and I like the little trick to keep the bolt on the socket from losing it

[@speedkar99]

Thanks I'm glad you appreciate my video

[@luisamoa2500]

Your toothbrush always cracks me up. :)

[@speedkar99]

+luis amoa haha

[@EddyGurge]

It's not his. It's his brother's. And he almost melted it on the hot alternator.

[@TikiHutDWI]

Hey dude, thanks for this awesome video. I watched it probably 40 times over the course of the week I spent replacing my alternator. Every part of this was so helpful. Big props to you for putting this together. Thanks so much.

[@GPerformance]

I just had the same symptoms on my 07 GS 350 while driving. your guide is just perfect - i love you for that. My Lexus just has 120k miles on it and the first alternator.

[@theodorenickel7462]

THis is one of the very best instructional vids I have watched to date. No nonsense about things that don't count. Thank you so much. Mine destroyed itself so bad it sucked the battery dry in very short order. Thanks to you, there is light at the end of the tunnel.

[@speedkar99]

You are welcome. Now I'm replacing the alternator on a Mazda 3

[@hang3xc1]

THis is the best video I've found for this particular job. THANKS !

[@speedkar99]

You are welcome. 😊

[@RodMo1911]

Man, this video just saved me a $1000. I changed it Sunday with very little problems. The only hard part was that bracket and bolt that’s in the back. I’m back rolling now. Great video. Thanks again!!!

[@speedkar99]

Glad it helped

[@jumpinghighest]

Great video. Well explained. Love the tooth brush!

[@speedkar99]

Thanks to my brothers teach-brush

[@Danny-ed4tn]

I have a 06 lexus is250 i went to autozone and replaced my battery but they told my altenator was bad but my car start right up with the new battery and dont give me none of those signals....thats means the altenator is good than right???

[@iPervy]

Man that tip with using tape on the nut made this video worth watching all by itself haha. Had times when that would have saved me big time. Great video all the way speedkar! Really would like to see you do more of these fixing videos as well!

[@speedkar99]

+iPervy thanks I'm glad you found that tip useful. Some people will stuff a tissue inside the socket so the nut is a snug fit, that works too but seems more risky. And yes- there will be more DIY auto repair videos to come, in the past year I focused more on how stuff works but you can check out some of my older DIYs from 2016 and before

[@samsonn25]

[@AyadrixBF]

Best Alternator replacement guide so far. Thank you for putting in the effort to film it!

[@speedkar99]

Wow, thanks!

[@AustinCoulson]

Awesome video. Was almost exactly the same on a 2014 GS350. Made the job a lot quicker as that bracket on the bottom is hard to see.

[@speedkar99]

Yes the 4th gen GS is the same mechanically

[@AustinCoulson]

@@speedkar99 Your vids are awesome. I learned as much from your great editing as I did the job.

[@IceESole]

Any suggestions where to buy a new alternator? I have a 2010 lexus 350gs

[@kevindeuvall2155]

Thank you. Your video was helpful when I replaced the alt. on my 07 GS350. Of course the hardest part was the rear bolt. The thing that helped the most was to place form padding across the top of the engine and lay on top of it. This allowed my left arm & hand to the correct angle to fit easily down the hole and access the stud / nut with a deep 12mm socket & 3” extension to remove / reinstall the nut. Thanks for taking the time to post your video.

[@RJ-pw9ij]

Why do they have so many fasteners for an alternator lol? It ain’t going nowhere, Toyota!

[@christophermccolm4156]

Great video once again! 😀 That's a clever trick about using tape to hold a bolt onto a socket--I'll have to remember that one. 👍

[@speedkar99]

+Christopher McColm thanks- definitely a tip you should use if you don't want to be hunting for nuts at the bottom of your engine bay when they fall!

[@Timetryp]

Very thorough and detailed video - excellent job!

[@notsoserious0944]

I'm the fat neighbor guy looking over your shoulder and drinking a beer. LOL.

[@speedkar99]

+notsoserious09 haha! sorry bud I only work on my own cars 😉

[@jimmyaab]

Thank you for your video, I did it on a 2008 IS350, had to remove the upper radiator hose as well but pretty much the same process, the 12mm nut behind was put there by the devil himself, but with a magnetic socket wasn't that bad, lots of scratches on the arm tho.

[@speedkar99]

Magnet socket is even better than the magnet I used

[@zhiyonghe850]

Battery light came on and off on my 2008 GS350 for a few weeks, but becoming on more frequent and longer overtime. Voltage was on low end of spec (13.7 just after start, and 13.3v when warmed up, 12.6v with heavy load), so it was still charging. I used a cheap Amazon video scope connected to my phone so I can put the socket on the stud in one try. In place of the tape, I simply used a small piece of paper towel between the nut and socket.

[@speedkar99]

Thanks for the tip

[@camiloisla]

Muchas gracias por este video, solucionó lo que nadie pudo. Muchas Gracias desde Chile 🇨🇱

[@nelsonflores2429]

Dude I have been stuck at that rear bracket for 2 days I cannot get the motherfr off! Argh! Any tips!

[@Nmakemoney]

Any luck man? Struggling here

[@koalabear5286]

I have a 2007 Lexus ex at 250000 km. I'm gonna replace the water pump as preventive maintenance. Should I replace the alternator along with it? Or should Rx alternator last much longer?

[@speedkar99]

I'm not sure if you meant ES or RX Changing the water pump on those are a bit tight... I'd wait until early signs of failure such as noise or leakage. Alternator shouldn't have to be changed until signs of failure as well...that's not preventative maintenance.

[@amccoyjr8]

Man! You have no idea how much your video helped me with installing the alternator on my 08 Lexus GS 350 AWD. All of your tips on camera work were spot on. Thank you kind Sir!

[@speedkar99]

+Arthur McCoy awesome! I'm glad it helped. For the AWD did you have to loosen the compressor, or were you able to wiggle it out ?

[@amccoyjr8]

speedkar99 No need to loosen the compressor. Once I removed the wire bracket on the right side,(10mm bolt), I was able to wiggle her out pretty easily.

[@speedkar99]

+Arthur McCoy good to know, I read it's much harder on the AWD on the forums

[@mrflamewars]

Touchscreen HVAC and radio controls are the work of beelzebub. What was wrong with a knob? is a knob not cool enough? You can fondle knobs and buttons and figure shit out while you're going along and make what you want to happen, happen, without looking away from the road.

[@speedkar99]

+John I thought the same way when I first got this car, but after a year and half of using it, I rarely use the touchscreen! Since the HVAC is automatic and the radio has dedicated hard buttons the touchscreen is only for advanced or custom settings which I don't need daily. I'd say Lexus did it well compared to other manufacturers, the only hardkey I miss is fan speed.

[@skbenergy]

awesome video...big help for me...by the way is that a 4GR-FSE engine ?

[@speedkar99]

2GR

[@skbenergy]

@@speedkar99 I drive a Toyota Mark X that has a 4GR-FSE engine.....they pretty much look almost identical so i guess this video can work for when my alternator goes bad...awesome video many thanks and island greetigns from the Caribbean :) !!!

Great video...but after following step by step....my alternator isn’t coming out on my 2010 GS 350

[@speedkar99]

Alot of people seem to have seized alternators...hmm

[@5tag5]

This video and the write up on ClubLexus were both very helpful! Couldn't have done it without this; never would have found the back bracket and would've had to pay the dealer. Thank you!! 2007 GS350 AWD. No issue getting the alternator off and back on with the AC compressor in place. Plenty of other issues getting everything put back together in tight quarters...

[@speedkar99]

Thanks for the feedback on the AWD model, I heard on those it's a bit more difficult. Glad the video helped!

[@demonshangover]

Hi, this is the best video I ran across on removing the alternator … it seems easy for you to remove the connector … I have having a heck of a time and still cannot unplug that thing. Is there a trick on how to remove the connectors? Is there a “latch” that must be pressed? Thanks for the awesome video!

[@boosted2.4_sky]

Nice. Those hidden bolts are a pita.

[@speedkar99]

+Craig Cundiff yes it's really tight along the side of the alternator. I don't see the point of that bracket

[@deasttn]

A lil grease in the socket is another way to help hold a nut

Sharing some info 3 years after this vid: Same problem on my 2007 IS300 at 130k miles. It seems that Lexus has tuned those alternators to fail after 100k miles. Same thing with my engine starter, it failed at 110k miles. Same with my friend's LS460. So if you are a Lexus owner, you know when to expect those fails.

When headed to the parts store...do your research so you get the correct AMP for your model. In most cases...the parts store will give it the SWAG method...SOME WILD ASS GUESS.

Yupp it worked, but I had to drop the ac compressor, thinking about drilling out the stud and use a regular 12mm bolt in. Soo pointless to have the bracket, but I can see it may be needed when going 180mph

[@speedkar99]

It's just extra security

[@TobbeArnesson]

On my alternator it was blown diodes that was the culprit. After a lot of searching I found a replacement rectifier. The old one was filed off from the windings and the new one has to be hard soldered back in. Search for: Mobiletron RN-34 (rectifier) Mobiletron BH-ND06 or BH-ND12 (brushes, not sure what the difference is - I bought both to be sure) Different brand: AS-PL ARC6043 (rectifier) AS-PL ABH6004S (brushes)

[@michaelserrano7097]

I changed my battery and when i checked the readings, my alternator was giving 13.8 in iddle no load and getting to 12.7 with some load ( with the new battery). The following day my alternator was giving 14.2 volts with load. What was that!? Some kind of self protection or resetting of the computer??

Very good video that I had much use of today - thank you! On my IS250 RWD 2008 there are a few differences with the radiator. There was not enough space between the electric fan and the engine to get the alternator out. I contemplated removing the radiator, but there's a hard line thin radiator sandwiched in front (Aircon?), so I didn't want to disconnect it. Instead I sawed (!) away part of the cage for the fan and disconnected the top radiator hose. That gave me the space needed to get the alternator out. 🙃
