Just got a quote for 1300 dollars for BIG O to do this for me. I immediately had it towed home. Thanks for the savings! Fingers crossed my goes as smooth as yours!
Thanks for the video. It was helpful in completing the job, however here are some tips to others who may attempt this:
1.) Removing the radiator will provide much easier access during removal and reinstall
Without removing the radiator will require you to contort your hands in awkward, tight spaces and may require special tools that the average garage may not have.
By removing the radiator one would also prevent damage to the condenser during removal/re-installation
2.) If your car is old enough, the nipple where the return hose connects to radiator cover/neck WILL break. This part can be separately removed without replacing entire radiator and should be available at your local parts store. Easy to remove and reinstall: Remove collar and gently push it backwards toward fire wall (see new part to get idea on how to remove)
3.) Serpentine belt is best removed by:
Jacking the vehicle up and remove the passenger side wheel
Remove the skirt that covers the serpentine belt area (Two 10mm and 1 push pin)
Use 14mm wrench (the longer the better) or slim socket wrench to pull DOWN and to the FRONT of vehicle on the tensioner bolt
Remove belt from the left most accessory at the bottom of the pulley
Then go back up top and remove from alternator
To reinstall, place belt back on alternator, loosen tensioner, and reattach belt to pulley
4.) Alternator bolt removal:
a.) Remove upper bolt of alternator from the top of vehicle (14mm)
b.) LOOSEN the lower/left bolt using a breaker bar w/14 mm socket or wrench with extension.
**Chances are you will not be able to remove the entire bolt from the top using a wrench/socket combination because of the limited space
c.) Continue to remove the lower/left bolt (14mm) from the bottom of the vehicle
You may have to lay on your back and reach up with left hand to remove the remainder of the bolt.
d.) Third, lower/right bolt (12mm) removal:
--Remove dipstick (10mm)
--Remove exhaust manifold heat shield (no need to remove O2 sensor)
--Use short extension and wrench to remove the bolt
****This bolt will FALL into the bowels of the car!! Have a magnetic pickup tool ready
Hopefully you have already removed the under skirting, for this is the only way to retrieve it
During reinstall I dropped it at least 10 TIMES!!! Each time it fell in the same exact spot!! ***
5.) If you DID NOT remove radiator, place a piece of cardboard or board in front of radiator to protect the condenser as you remove/reinstall alternator (this will however give you less space to remove alternator)
--If you skip this step wear some light duty gloves while removing alternator and use the back of your hand to position between condenser during removal/installation.
***The Third Bolt Re-installation**
DO NOT tighten the other two bolts, this will allow some wiggle room to install the 12mm bolt while the alternator is in close alignment because of the other 2 bolts... I made the mistake of tightening the lower 14mm bolt and caught hell trying to get the 12mm installed... It is only AFTER I loosened the other 2 14mm bolts was I able to successfully install the 12mm on the 1st!! try!!
Good luck!!
Very thorough! Thank you for the helpful tips for others completing this job easier!
FYI for anyone contemplating the job and researching on TH-cam - there is absolutely no need to remove the radiator fans assembly in order to remove the alternator. You undo the water inlet hose and remove the thermostat housing (two 10mm nuts + the 14mm idler pulley bolt) and remove the three screws holding the ABS brake unit to the chassis which then allows enough room to manoeuvre the alternator out.
If you are not intending to replace the serpentine belt, you can get away without removing the front wheel and access panel (just work on the idler/tensioner from overhead).
The only mildly tricky thing is removal of the rear alternator bolt because you can't see what's there. The alternator is bolted to the block with a bracket (google part number 125110P010 for a picture). Use a deep 12mm socket to remove the bracket from the block and you can then free the alternator enough to access the other bolt and remove the bracket from the alternator.
Good job bro , you have the only video literally on the RX350 . This is a blessing bro thank you . I have an alternator job in the morning and have never touched a Lexus . This is super informative
Yeah I know! I noticed there were no videos on on an rx alternator replacement so I decided to make one! Thank you! I appreciate it!
How did your repair go? I might be tackling this in 6-7 hours. It's incredible how much harder it is on the lexus than the avalons.
What Took The Longer For Me, Was Putting Back The Belt!! 😡
Thank You For The Video!! 😊
Great video but some tips for others as I just did this job myself- took about 6 hours. 2009 RX 350 with 172K miles, it started having real issues two weeks, light came on a few days ago,, but it was noisy for the last few thousand miles. Tough job for guys with larger hands as you'll have less maneuvering space but it's doable.
1. You'll probably break the bolts for the cover underneath, rusted to hell on mine. Air intake bolts might break off too, one of mine did. Exhaust manifold bolts might be rusted to hell, spray some pb blaster in case.
2. If you break the engine coolant filler neck accidently, Dorman sells the part, #902-408. Good to have in hand and return if not needed. If you do need it, break off the plastic retainer clip, use some wrench/locking plier to get a grip on it, and wiggle it off while using something to pry it off. Careful getting the broken plastic pieces inside the hose out- face it downwards and hope for the best. New one should go back right in with some suggestive tapping.
3. When it comes to the third bolt in the back, you don't actually have to remove initially to get the alternator off- you can just go straight in following the compressor line and the bolt for the bracket mounting to the engine block is right there, 12mm. You will have to take the exhaust manifold off first, don't need to touch the dipstick. You can wiggle the alternator out after taking that bolt out then actually remove the bolt connecting the bracket to the alternator out after. There is a line/wire connected to this bracket so you will have to take it off.
4. When it comes to wiggling the alternator out, I found it extremely helpful to pry the top, knock it back in with a wrench (anything's a hammer), then pry again and repeat and it will eventually loosen itself. You will have to pull it up from the bottom and start to maneuver it out that way. I believe my alternator pulley was facing downwards/towards the inside of the car for me to get it out. Replacing with another unit was extremely easy as it almost slipped right in. If you un did the bracket, finagle the bolt onto the alternator first but do not tighten all the way. When you get the alternator lined up for install, put in the top bolt, bottom left bolt, then bolt it into the engine. Tighten all the bolts down at this point
5. I found removing/replacing the belt is easiest with two people even if you do put a bolt in to hold it un tensioned. Getting it back on is extremely tough for your last pulley without having it un tensioned fully. Use two wrenches/breaker bar to get it loose. Then putting it back on have someone help or you may never finagle enough clearance to get the belt back on right.
6. Under air intake tube was annoying since you can't see that far back, until you realize it has to pivot off the clear res underneath. Use that as a pivot point and eventually you should get it to fit back into the air intake box easily.
7. I had new pulleys on hand but when it started getting late and I spun all the pulleys and didn't feel any resistance/grinding or hear any noise, I decided to just leave them there. Yes I should have gotten them replaced since I was there but it's a simple enough job that I can do it another time when I really have some issues. They're going back to amazon in the meantime.
Just wanna thank you for your effort very detailed enough to learn to change my own alternator which works like a charm now. Great work.
Fiona Jeffries awesome! I'm so glad my video was helpful to you! It's really cool that you did it yourself, not only does it save you a ton of money but it gives you a sense of accomplishment! Bravo!
Thanks so much for this video! Note on the 10mm bolt on the back attaches to a bracket - I actually removed the nut/bolt assembly from the exhaust manifold, then when the alternator was loose, removed the 10mm bolt. Repeated the process on install. Thanks again.
I replaced my alternator with special thanks to your video. Thank you so much for posting keep up the great work.
icecoled007 awesome! I'm glad I could be of assistance.
You didn't show us how you take the alternator out
THANKS YOU for the effort! Helped me a TON! I agree with Flynn Blu that it's a little easier to remove the back bracket rather than the dipstick - but whatever works! It's still a pain! Thanks again!
Thank you for watching!
Excellent video sir! Bravo for taking the time to do this.
Only thing I would mention is that when you were commenting on the electrical connections at the alternator, you refer to the main cable as a “ground” cable... it’s NOT a ground, it’s the main battery charge cable! This is a critical difference and could cause someone some serious damage if they do not understand this. That being said, if they follow your recommendation to disconnect the ground cable ahead of time, it will be safe anyhow.
Thank you again for the excellent quality video!
Awesome observation! Thanks for the input and correction.
Awesome man..keep it up..it came in pretty handy today..thanks
Very well done. I wish it was available a couple of years ago - couldn't figure it out so took the car to a mechanic and OUCH - $$$$
How much did it cost you and when was this & where
Great video with nice camera angles and recommendations for getting it done! This job is looking like a doozy compared to my TL already lol.
Thanks for this video. Great instructions. I took a break on the backside bolt and ended up read some comments. Figured out to remove the bracket from manifold and made it way easier. Total time getting the alternator out was 1 1/2 hours. I have to go pick up a new remanufactured one tomorrow. Put my battery on a trickle charge in the meantime.
Thats awesome I love when my videos are able to help people DIY!
@@LifeTac finished up the next day. It took close to 3 hours. It was easy getting back in but just a pain getting everything back together. I tried getting the bolt/bracket on the back of the alternator back on but finally gave up. I have also hated the cover underneath the radiator for a long time!
Thanks mate ! Pulled it out . Waiting for the part to arrive ..
Glad it helped
Mentioning the service access panel under the front passenger wheel well would have been nice. Something like 2 10mm bolts and you have easy access to your serpentine system and lower alternator bolt
You must remove the lower wheel arch cover (2 x 10mm) to remove/replace the serpentine belt. Also removing the tensioner pulley and then its bolt makes for easier lower alt. bolt removal/replacement.
I just used a bolt to stick in the whole on the bottom of the tensioner pulley lined up with the rectangle slot it gives easy access to the bottom alternator bolt. My problem was the 12mm bolt hidden
Oh yes you are right
I did my Lexus alternator
Yesterday and even
Have easy way to pull
The Alternator out on the little
Bracket behind the alternator
I just pull the front bolt
And the stud and that saved
Me probably a good hour
Of messing with the lower
Bolt it's a very good trick
And when i put the
Alternator back I put the
Bracket first and is better
And faster way
Very helpful for my first Alternator replacement (310,000 Kms). The 12mm lower inside bolt was the most difficult to get out. There is a 10mm nut on that bracket that would make it much easier to get out. The bracket stays with the alternator on removal.
Awesome tip! Also what a daunting job for your first alternator! Props to you!
U@@LifeTac I also found that removing the belt tensioner bolt (LH thread) made the lower alternator bolt very easy to remove/install. After fitting the new alternator, replace the tensioner, pulley and slip a 6mm drill into the loading hole of the tensioner and have it fully loaded before installing the belt. Took 3 minutes to load the belt. Would attach some photos if knew how. Lexus wanted AU$860 for a new Alt. but found one new for AU$270.
You are a good mechanic. Thank you
Thank you so much! That means Alot! Appreciate the support
This is definitely not as easy as a Ford... "Honey, can you go change the alternator on the Lexus before the Xmas party tonight?" Yikes, I have 4 hours and I'm starting now.
Nice Video, here's to 1 million views brother! I'll give you 3 or 4 today with a like and a comment. Good luck on your rise up
Amateur Adventurer thank you for your words energy and support! We need more people like you in this world! You can contact me or call me if you have any questions. Just lmk if you want my number
Thanks for this video. I was able to successfully replace my alternator using this video. There are two important things missing in this video.
1. How to remove the belt from the alternator
2. How to remove the alternator itself
To remove the alternator belt, it’s easiest to simply remove the front right passenger wheel and the plastic wheel well cover which will give you access to the belt pulley. You can use a long wrench and shift the pulley to loosen and remount the belt. It’s easy this way. The pulley does not need to be removed. You can see a video of the pulley here:
th-cam.com/video/zRfvf7-EcAw/w-d-xo.html
To remove the alternator itself, remove the top bolt which is visible from the top of the car then remove the bottom left bolt which is clearly visible from the passenger wheel well which you access to remove the alternator belt. The hard part is getting out the screw on the right side of the alternator. To remove that screw, you first have to remove the bracket screw that’s attached to the alternator screw on the right. A picture of that screw can be found at :31 of the video below. Do not follow the rest of the video below which shows to remove the pulley itself. That’s not needed! Once you remove the screw in the picture below, you can then remove the 3rd alternator screw on the right side.
th-cam.com/video/IAgFfeWbaMQ/w-d-xo.html
Good luck! This was my first time doing this and it took me almost 6 hours to do it. 4 to remove the alternator and 2 to install the new one and put everything back together.
That's is awesome! It's always great to hear when people DIY. There is no greater feeling of accomplishment. Thank you for your tips and I appreciate the feedback. Alot of people have mentioned that I forgot those 2 crucial components of the job, and for that I greatly apologize.
Just did my car you’re video was very helpful the bottom bolt was hard by the dipstick I left it off my hand could not reach it and turn my car is 08 worked fine
That’s awesome! I love when people have the confidence to do this job after watching my video! I know I left out a couple details but I think people can still perform the job!
Job well done!!!
Have you replaced CRANKSHAFT POSITION SENSOR?
Also, for both number two, the bottom alternator bolt at the side of the serpentine belt, take a little extra time and get the air conditioning line out of your way, and the ABS pump, especially it's bracket loosened up will give you more wiggle room
And, it's no fun, but will save you a lot of trouble to just remove the radiator hose from the water pump.
This is the best video to fix rx350 step by step and Wich tools to use
Not all RX350s from this era have that third bolt and bracket assembly - my 2008 does not - so even if it is present it likely is possible to leave it off. I used the method shown on another video to zip tie a serpentine belt tool to the motor mount to keep tension off the tensioner. The factory manual specifies removal of the radiator fan assembly. I would hate to attempt removal of the alternator with the fans in place.
Great job bro
Two bolts hold it in and the third one at the bottom is a nut. I didn't need to remove dipstick or us swivel. Extension alone was good. I also found that doing the bottom bolt it was better to do from in the front wheel area. Wheel and panel off to take belt off anyway. Putting alt back in I found that the first mount to line up was the stud down by the dipstick. Fell into place so to speak after that. Taking apart took just about 3 hours. Replacing took 1.5 hours. Sippin beers while doing it. Good overall vid thou.
Awesome tips! I like to see other peoples input! It helps others as well as me! Thanks for watching
@@LifeTac yes. Thanks. You did great....:)
Any recommendations on how I can short my alternator, my alternator is making an ugly noise like if the bearing is bad, and yes I have already found out it is the alternator.... I currently have a warranty on the vehicle that covers the alternator but they only cover it if it fails to charge not for making noise, so I want to make it not charge so then they can cover it cause it is making a very ugly noise but the bastard does not want to stop charging... I need it to stop charging
An endoscope works great for viewing areas you cannot see under the hood especially when you don't have a car lift!
would it be idle to change the pulleys and tensioner assembly and or water pump while doing this job? i have approx 160K miles clocked in..
dude how you took the belt out
having messed up a very expensive condenser while doing a job like this, I suggest we all find a way to shield the condenser on the radiator unit while we are doing this job because the bottom bold of this alternator is really hard to get to.. My suggestion is the remove it.
good job
Is there anything else you guys recommend changing or replacing in the LEXUS while its open from this alternator job???
hello, WHAT BRAND OF ALTERNATOR DO YOU RECOMMEND?? 130AMP? ANY PARTICULAR ONE YOU RECOMMEND?
Thanks for an awesome video. I probably spend 2 hours taking out the hidden back bolt. The trick for me was to remove the manifold plate which opened up loads of room to maneuver. With the plate pushed to one side it took me a few seconds to get it out.
Really. Very easy for me. But I first accidentally removed the manifold bolt. AMD after struggling to remove the alternator I got under the car AMD was like fuckkkkk the bolts still on AMD it was the manifold. After that I removed AMD reinstalled the right bolt AMD bam. Off like a charm
I'm thinking just doing water pump, thermostat and by the way do the alternator on my 07 rx350. It seems too much work just for the alternator I will just do all and don't worry about it later.
Awesome video! Do you think the ES350 has enough room to pull the alternator without removing the radiator?
Taylor Brown thanks! Yes it should be the same
No there is not enough room to remove it with out removing the fan assembly, if you have to remove the fan assembly then you might as well remove the radiator too... It’s not that much extra work
Wendell Greenidge its ALOT more extra work. fan assembly is a couple of bolts and connectors. radiator is hoses, tranny lines, coolant drain, refill and burp system. that adds alot more time to service. what are you talking about?
Random Google Name I did it without removing the radiator. However, Toyota TSB states that removing the radiator is required but not necessary.
@@hedga001 ok cool. Ill have to check my manual, i thought it did say in the manual to remove. Cool that yours says its optional.
Did you use the 100 or 130 amp alternator? They say the 100 is for the ones without the towing package and the 130 is the one for the ones with the towing. My 08 doesn’t appear to have a tow package and I know it doesn’t have AWD.
Same for me. Just pulled the old one out and took it with me to the parts store so they could match the part number. Was the more pricey one of course
How you get the 14on the bottom bolt
A VERY important detail: You must remove a stud from the exhaust manifold to get a grip on the 12 MM bolt that is on the inside lower tab.
This bolt is impossible to remove without doing this. Video makes it look easy, but it is not. I think I used every tool I own and many that I bought or borrowed!
Look up "replacing alternator on 2007 Toyota Camry V6" . Same engine.
gib472008 Yes, it’s the 3.5L 2GR-FE V6!
Did you install the alternator from the top or from the bottom? Also, great video sir!
G M Thanks! install from the top. 90% of the job is all done from the top
How many miles do you have on the car when the alternator went out.
Mine just went out at 169,000 miles
How many miles your 2007 Lexus RX350 had when you had to replace the alternator, because this part should last a long time?
I know mine today has 105k and have to replace today
2008 here, 200k until it failed
2007 here 202 k
Where are you located? How much do you charge to change mine? I dont have the tools.
Trevon Ellis I'm in chino California and id charge about $450 for this job
That bottom screw can be removed easier if you remove the heat shield.
No need... The bottom bolt attaches to a 90° bracket which goes straight into the engine block. A 12 mm straight on will take it off and save you a hell of a lot of trouble.
What a fucking pain in the ass.
First, thanks for the video! You made all the difference. I tried to do the same with this one on that car's transmission filter: th-cam.com/video/92pc9fCvK4c/w-d-xo.html
Here are some lessons learned:
- Buy and install a new serpentine belt. It’s time and you’ll save $100 in labor.
- Buy and install a new radiator filler neck. On the earlier RX350s, they’re notorious for breaking off at the bottom hose and, potentially, destroying the engine for lack of cooling.
- Gather cardboard to protect the radiator, a headlamp, a 2” nail, serpentine belt installation diagram and a magnetic grabber.
- Take photos of everything before you take it apart.
- You don’t need to loosen the dipstick but you do need to shift the exhaust manifold shield out of the way.
- Cover the radiator fins with cardboard after removing the fan.
- My hand won’t fit between the alternator and hoses from the top. That’s why getting to the bottom bolt from below proved to be so important. Same for the belt tensioner.
- Remove the passenger wheel and the cover over the belt. Find the belt tensioner at 2 o'clock from the big crankshaft pulley at the bottom of the engine. See the hole at the end of the tensioner arm? When you twist the tensioner to the left with a 14mm wrench on the nut, you’ll be able to pin it out of the way with the nail slipped through that hole and into the slot you see in the engine block. Remove the belt. That will expose the bottom alternator bolt and prep for the new belt.
- The light gray electrical connector you need to disconnect below the alternator has a locking clip hidden at the bottom. Remove it from below.
- The driver-side bracket on the alternator is tough. First, remove the nut holding it onto the engine. Pull the alternator off that bracket’s bolt, twist the alternator to expose the bolt holding the bracket to the alternator, and remove the bracket. That makes removing the alternator much easier. To install, put the new alternator in about that same place, then attach the bracket to the alternator, then finally fix the bracket to the engine.
Thanks again!
Bro how much was it?
didnt show how to get bottom bolt out of the front
How many miles did you get out of the original alternator?
Mine went at 168000 km
Jay Dahl My 08 went 264,000
I got 310,000kms on my 2008 RX350
How long did you take you to do the whole job?
Zhanpeng Feng it took me about 2 1/2 hours with recording but for the regular person you can look to expect about 4+ hours
LifeTac Thanks for the prompt reply. Is your $450 estimate labor only or is it parts included?
Zhanpeng Feng I don't remember. I think I charged 450 parts and labor but normally this is about a 600-700 repair
Was my first time and with the right knowhow it was almost 6 hours with the trip to the parts store.
The most important part was to show that hidden bolt.wich wasnt shown Its Much easier to un bolt ac compressor to get to that bolt.
vincent milano You don’t need to remove the AC compressor to remove that bolt. You unbolt the bolt strait next to the hidden one on the same bracket. Then you unbolt the hidden bolt once you get the alternator out and bolt the bracket to the new alternator.
m.th-cam.com/video/IAgFfeWbaMQ/w-d-xo.html
This may be worse than the water pump i just replaced on my rx
How many mile , alternator out
It depends it's usually as round 100 - 150k maybe even longer. But you should have a battery light on the dash most likely indicating weak alternator
@@LifeTac mine just went out today at 105k. I think its cause the job I have requires security lights which then drains some battery while the lights and radio is on. And when having to do patrols it's over works my alternator to recharge constantly. Only reason i can think why it went out at 105k
Please include the link for alternator in the description as well
Good thinking!
@@LifeTac yeah please. I will be waiting ;-)
@@LifeTac great help. Thanks alot man!!
tried to show everything except removing and replacing the alternator. what heck?
9:57 - T the bottom bolt attaches to a 90° bracket which goes straight into the engine block. A 12 mm bolt goes into the engine block straight on.
Don't mess with that really hard to reach both on the alternator. You will save a lot of time and angst by just going and looking at the bracket. Then just undo that bolt . There is no need for any swivel fitting for your ratchet.
I don't care how much someone would pay, I'd never do this again. Be warned everything that can go wrong on a 12 year old car will go wrong!
Yeah this job is not for the faint of hearted people. Must be pretty mechanically inclined or very driven or motivated to do it yourself
@@LifeTac I consider myself very mechanically inclined but jeez on this rx350 everything was packed to tight. I could only do it by removing the front passenger tire. The new alternator I got was 0.5 cm too small to fit for the front bolt. That and it's -10 outside right now did not make this fun. Thanks for the video!
@@LifeTac I can admit it's a very tight job but once I figured all the right angles and saw that removing the passenger tire was easier. Going in was a total breeze. While I'll never have to work on this car again if I did it would be a breeze knowing all the bolts and angles. Only hard for a person who never touched it but a mechanic will do this at a breeze. Took me around 4-5 hrs but that's also including watching TH-cam videos and waiting for a second hand to come
This is wrong way to take Alternator, passengers wheel should take off, this is stupid way and got many good comment.
Did you seriously not put in the 3rd bolt on the bottom of the backside of the alternator?? Lol.
Ben Stephens I seriously did not put back the 3rd bolt. It's pointless I promise you.
First sign of a hack mechanic imo
I'm gonna put back the 3rd bolt.
Jacques Koorts I did and it wasn’t as bad as bad as you might think because I didn’t even have to use a u joint. You unbolt the bolt strait next to the hidden one on the same bracket with a deep 12mm socket, 3/8 preferably. Then you unbolt the hidden bolt once you get the alternator out and bolt the bracket to the new alternator with that hidden bolt. Then once you manage to get the alternator in it’s spot, like the bracket hole into the stud with the 2 alternator fasteners.
m.th-cam.com/video/IAgFfeWbaMQ/w-d-xo.html
Good effort, but keep working you rushed Alittle and became frustrated, there is a easier way to do that, your a new mechanic I can tell KEEP AT IT
I wouldn’t hire you to assembly a hot wheels car
