On this episode of FM, I'll walk you through the accessory belt tensioner test and replacement procedure on my LEXUS GS400. The test and replacement is similar across many other models. However, be sure to consult your specific FSM for your vehicle's procedure.
HISTORY
This resolved my tensioner issue that occurred when installing my XAT Racing Pulley Kit (episode is available here: • XAT Racing Aluminum Pu... ). XAT decided to solve my tensioner fitment issue by sending me a new 3UZ tensioner with their 3UZ pulley installed for use on my 1UZ VVT-i.
Replacement of the tensioner is a good preventative maintenance item as well, so even if the tests indicate yours is ok, it might be worth replacing it as a preventative measure. Typically we don't see tensioners as the cause for a thrown belt though; usually the bearing goes first and they get noisy.
PARTS
Tensioner: there are many options out there; select what's best for you. OEM is always a good option, but expensive.
Belt: Bando PN 6PK2240 has worked well for me.
XAT Racing Pulleys: xatracing.com/...
TOOLS
Basic hand tools
Ratchet set
Deep well 12mm socket for one nut (box wrench will work too)
Torque Wrench (5-35 lbf minimum range)

Snapped two belts the past two days and this is the only video I can find on the for the 1uz engine. Thank you for making these vids.
Thank you very much for going to the trouble of making this detailed video. It was the only one on UTube I've seen this detailed. Saved my butt
Wasn’t expecting this much labor . Not worried but I just started taking it apart then said . Ehhh I’ll take a break n watch TH-cam. Thanks for clarity
I watched it even though I would never attempt this...But wanted to thank you regardless,...Big fan of the channel! Thanks for all the great content/ideas/education! I ordered the spacers you promoted on the 3rd vid you posted for my 02 black GS430 all stock on OEM 17s! Look forward to the new look. Added you on the Gram as well! Happy Holidays FM!
damn i wish you showed how you put the timing over back on smh im struggling
Thanks🙏🏼 Really detailed video! Hope I’m able to get it done within 2 hours
Decided to change my belt after mechanic said it needed it. Belt actually looked pretty good so not sure what that was about.. 11lbs to move tensioner and it looks quite wobbly when running even with new belt.. And it's way out that arrow, 3 notch range as well.. May have to do this soon..
Following need to do this next
Haven't done this repair yet but as far as I can tell excellent production very useful and complete definitely deserve whatever credits coming your way on that thank you very much I believe this probably helped out a lot definitely subscribing.
I figured id drop 2 comments a d a like!
Here to support!
Thank you! Mutual respect!
great video! nice step by step instructions. Thank you
Sucks I ordered a set of XAT pulleys for my 1uz vvti and I waited 2 months and I only got 4 of the 5 pulleys because they said one wasn’t ready. Another problem I had was when I went to put the tensioner pulley on the tensioner sat too far inside the back of the pulley which was causing the pulley to not sit right resulting in it getting hung up on the engine. I didn’t receive my pulley kit until after I waited two months AND sent them an email asking what the problem was. They told me it was because one of the pulleys wasn’t ready which is weird because on their website and Instagram it says they are ready to ship. Also the person I emailed was being a little rude with me. Just putting this out there for all interested in ordering from them. BEWARE
Great video bud
First of all, thanks alot for the lovely vedio 😊
You mentioned in the vedio that the new belt tensioner you installed in your lovely car can be fit in 1UZFE engine .
Are you sure about that 🤔
I am gona say different way :
Is the OEM belt tensioner in Lexus LS400 1UZFE non VVTI engine, can fit in Lexus LS400 2UZFE VVTI engine as your car ?, it's the milion dollar question.
because some people say yes , and others say no .
I have LS400 96 non VVTI , I couldn't find OEM belt tensioner in our local Dealers , they said its discountenued, they have it only for LS400 98 99 2000 with 2UZFE 😢 wich also can fit in 3UZFE for LS430 from 2001 to 2006 .
That's way sir ,,, are you sure it can fit the 1UZFE?
If that's right, Kindly share me the link for it .
Thanks again.
Thanks for starting off by saying thanks. A lot of people don’t do that and they need better manners. Unfortunately the situation I found myself in with this video doesn’t allow me to answer your question. Here’s what happened: I ordered a pulley kit from XAT Racing. The tensioner pulley they provided would not fit on my engine. I told them, so they sent an entire tensioner assembly to me with no further information. Turns out that was an old pulley design and a couple years later the pulley came off the bearing entirely! So they sent me another pulley. That’s why I can’t answer your question. However, I think XAT Racing might be able to answer it for you. Also, you can try to cross reference part numbers using toyodiy: www.toyodiy.com/parts/q.html - I hope that helps!
@@ForwardMomentum thanks alot for the fast reply, 🙏
Keep doing what you do for your lovely 😍 car .
It's one of the best 👌 👍 GS400 in TH-cam. I like it so much, especially with manual transmission, and It is a rare wine red colour, I show it to my mechanic friend, he liked it a lot, because usually no one see a Lexus with a manual transmission.
You are an organized, dedicated person. You like to make everything clean and tidy. You are a person who only accepts the best, and only accepts that everything be in perfect condition. You are Intelligent, and always striving for perfection without getting tired, or desperate. All of these qualities are also present in me, and as I watch you working , I feel that I am the one doing this work. I still have my Lexus LS 400. Model 95, and now I have owned it for 19 years, and the odometer reading now is 626 thousand kilometres, and it is still as smooth as if it was new , and I did it myself as well alot of fixing with my own hand , good luck to you.
That’s the nicest thing anyone has said to me in a long time! So glad the vids are helping you out! 👊
Cool vid bro 👍🏼
I'm loving the vids Christian. What all exactly have you done in the engine bay?
Thanks! I try. Do you mean performance mods? Not a ton. Intake, exhaust, tune and modded VB.
What torque wrench do you have that clicks counterclockwise?
All of mine do as long as I switch the ratcheting mechanism. My big wrench is a Kobalt.
is this the same procedure for a 2007 Lexus Ls460
Sorry, I don’t know. You’ll have to look and see. Generally serpentine belt systems work like this.
Great video! As always.
And its never an easy job. Lol
You said OEM is expensive but I found XAT pulleys to be even more expensive. Am I right here?
If you can walk into a dealer and buy brand new pulleys cheaper than the XAT pulleys, I’ll be amazed. I’m not talking used off eBay or Chinese knockoffs, real brand new TOYOTA pulleys. Let me know the difference in pricing either way.
Is this the same for the 3uz ? Buddy my ls430 failed :(
Should be, yes.
Will this cause alternator problems?
Not unless it’s causing belt slip.
This is what I have to do to my car next , then on to the brake booster , how's yours??
My BMC is shot. It’s up next, along with the radiator.
Seems like Tensioner is my next replaceable. When are you doing a dor actuator video ? :-D
I have to get through this supercharger series first. Actuators are on the list. 😎
@@ForwardMomentum I mean you do the actuator video and you will have whole set of “need to know and how to fix for the 2GS”. ;-)
Any reasoning for using a 3UZ tensioner over 1UZ? Other than obvious weight savings. Weigh reduction>herspers
@@HussarPlays the pulley that XAT sent me didn’t fit on the 1UZ tensioner correctly. So they sent me a 3UZ and it worked great.
@@ForwardMomentum a ha, I understand.
So probably a good idea to include the tensioner replacement with the timing belt replacement.
Absolutely! Or as preventative maintenance.
That and the valve cover gasket, spark plug tube seals, and cam seals. But the cam seals sometimes last for two timing belts.
Great content. I have a 99 GS400, would you like a project car to work on for the channel?
You want to give me a GS4? 😳
So with the new tensioner it doesn’t move at 20 ft lb?
Correct. In fact it requires exactly 25lbf to move, which is perfect considering the margin of error for my non-calibrated torque wrench is probably 1-2%.
will this be the same for a 1uzvvti ls400?
The process should be the same. However, the part # could be different. Just plug it in at RockAuto or similar and see.
Hey I have a question about the vsc light that came on in my 1998 Lexus gs400 and was wondering what where some good ways to trouble shoot some of the problems if money is a bit of an issue
Get a cheap scan tool and check for codes. These cars love to trip all sorts of systems when it’s a simple, singular cause. Start with the DTCs.
@@ForwardMomentum I did that and to sort of an avail it was a vacuum leak but Im not sure if the power steering hoses or the pump itself because its a bit of a heavy leak would that cause tye vsc light to illuminate because of that or could that a problem because of the suspension
What was the code?
@@ForwardMomentumcode: P0171
@@charlescasineri8590 bank 1 lean. Check the entire intake system post MAF for leaks. Common problem areas are the resonator box and lines, and at the bend at the throttle body (the tube cracks on bottom). Check the entire thing very carefully.
Can you tell us what brand tensioner that is please?
I don’t know. XAT sent it to me. I’m sure they would tell you. Sorry!
@@ForwardMomentum ok thanks also I was wondering what hassle you had to go thru when you ordered the pulleys? I want to order some but don’t want and hassle or anything.
Several months later - was the xat pulley set worth it?
For my needs and how little I care about engine dress up items, I would say no, not for me. If the price point was around $125-$150, perhaps. Another thing is that I run the stock intake and it covers quite a bit of the front of the engine anyway. Just my thoughts...
@@ForwardMomentum I understand. I have a squeak coming from a pulley (probably the tensioner) and was curious if I should replace them all or not (minus the crank of course). Thank you
It’s a fair question that probably only you can answer. The XAT kit is probably much cheaper than replacing all the same pulleys at the dealer. So there is that on the plus side. 😎
Do you have a direct contact ?
Not understanding. Can you expand on the question please?
Is it possible to talk over the phone ?
Unfortunately no. I’m not a shop and only have a work phone.
Toyota is going way south on its design…
