Just want to say this channels dope! I live in America and I just got a 1991 RHD Celsior. This engine seemed big and daunting doing maintenance until I started watching your videos. This engine is amazing and not that hard to work on. Cheers
Cool as. Attitude is the key. These engines are simple with some know how. Cheers Kelvin
I could have saved myself so much bloody time if I just watched this video. I straight up thought the big tabs on the cam gears were the timing indicators. 😭
Glad I found this channel! So much 1UZ information. I picked one up yesterday for my 1UZ IS300 project!
by far the most helpful one of these I've seen
Thanks. I have a longer one too. ruclips.net/video/pCk18Q8CxtQ/видео.html
Thank you for the detailed install Kelvin...this is a perfect reference video !
Thanks Billy. The intention of this whole series was a reference for questions I'm frequently asked. I can politely pass on a video and spend time making more, oh and working. Cheers Kelvin.
Thanks for this video, re doing my timing belt as the previous owner did it wrong on my sc400. Picked it up for dirt cheap.
Always a few little extra hints and tips in these videos, great work and thanks.
Sometimes I feel like I'm repeating myself but I'm getting used to it as you say, always something new too. Cheers Kelvin
Hi sir what is causing my 1994 Lexus sc400 to do a hard shift...does the ecu have anything to do with it.
Could be lots of things, including ecu, best do some testing
@@CartuneNZ sent my ecu to get repaired by ECUREPAIR on Ebay...put it in and car runs like a lawnmower
@@kangokidkidd4037 doesnt sound ideal. Might want to confirm exact issue and repair as required
Very expertly done thanks for making this video
Once again super clutch 🎉 thank you
No problem 👍
All my cars have been old Mercedes, but this engine is just amazing.
Thanks for the inspiration. I have made a camwheel tool today
Nice work!
Always great to look it again bevore touching the belt. It seems my tensioner spring didn't like to bath in saltwater and lost tension. It was a good idea to open the covers bevore starting the engine.
well done. Cheers Kelvin
Hey Kelvin, as usual, love the videos. Most I watch to see one tiny part of the engine just to see how something is bolted in, or a certain mark on the engine. (Such as these timing marks) I just did another T-belt on a 93 LS400 and the timing was off when I finished. 1st time this ever happened to me. I ended up using a wrong mark on the left cam gear. There's more then one notch on the back side. I never marked it when I had it off so I was going by touch to find it because I couldn't see anything with the bad lighting I had. I finally realized it when I spun the crank around the 2 times again. I saw a tiny notch mark on the front of the left cam gear which lines up with a different notch then I was using on the back. I noticed, and you mentioned in this video, the cam gear you used doesn't have the notch on the front. If I can miss that, then some of the newbie mechanics can surely miss it and maybe mention it in future videos of the timing belt.
EDIT: I just noticed on this other video of yours has the front mark; ruclips.net/video/S4eYWRR1C3U/видео.html&ab_channel=CartuneNZ
After all that, I do have one question. The cam gears should be torqued at 80 ft lbs. I see you just used your muscle torque wrench (the best way) to tighten them, which looked alot more then 80 ft lbs. Would it matter anything with the cam itself being tightened way too much?
Keep up the good work and thanks for the time you take to make these videos and answer questions and still be able to do your business side of everything also.

I am careful with my arm torque. Its interesting what people notice in my videos. I havent chatted about how some pulleys have marks on the front and some don't but you were able to spot it. Cheers Kelvin
How do I time the crank with the cams of the pulley and the gear are both off the crankshaft
Do u have a video installing the front loom
😂😂 I was doing diagnostic on my 97 1uz. Because it was acting weird during a drift event but sent it. Turns out the crank was off by 4 teeth. I guess that explains slight misfire and it would limp at 3k rpm. Hope its isn't totaled
Once again Thanks for this amazing video Kelvin
I rotated my engine counter-clockwise, only saw later that it should have been clockwise, could this cause me issues in the future
Thanks in advance bud
hello friend, good morning, joshep greets you from peru, I tell you that the 1uz fe in peru is not very commercial, however I got one but I have a problem the timing belt temperer does not tighten the pulley I remove the trigger but it stays loose the belt, I would like to know if the 1uz and 2uz hydraulic tempers vary because we import the temper and the water pump and oil pump as well and the 209-tooth belt but I have this problem, please I need your help with this problem since you are an expert in the 1uz faith
TY.💫💜
thanks
Is a Helicoil kit the way to go for repairing the stripped tensioner threads? Thanks for the great videos.
yes. Fitted properly it will be as strong as factory
The cover that everone forgets to put in that you mention at 3:00. Do you have any spare laying around by any chance as it seems it unfortunately wasn't there on my engine.
Thats one one I have had heaps of questions about recently. I happen to have found some brand new ones which were dead stock at a dealer. Dont come with the little gasket runner bit on the back but should solve a few issues for guys. Cheers Kelvin
I’m trying to do the timing belt and water pump replacement but when I try lining up the timing marks , the cam
Shafts line up but the crank pulley is still not lined up and still needs to be rotated more to line up but that would just rotate the cams and mis align em
ok. Hopefully you got it sorted. Cheers Kelvin
Hi Kelvin, I recently bought my first vehicle with a Lexus 1UZ engine. I would appreciate it if you could give some advice on the most critical things to check or test on these engines when you take ownership. It runs beautifully, but I would obviously like to get to know it so that I can keep it going like it is. Cheers!
Hello. Basic maintenence is first up, oil , filter , air filter , cabin filter , fuel filter, trans filter and oil , diff oil. Cambelt if required. Antifreeze. If its an older UZ tappet cover gaskets and engine connectors , if its newer AVIS solenoid. Cheers Kelvin
Can someone link me the next video
Any reason my cam gear timing marks would not line up at all but my engine(not well) ran before dissambly. junkyard engine, will not accelerate under load. There are tabs at the back cam gear sticking up. Should I use those tabs to line up to the timing marks on the engine, or use the grooves on the front of the cam gear like normal. The tabs in back are closer to lining up at tdc. L on, R 3 teeth off. I can't ever get the grooves in front to line up. I don't see how this engine ran in its current state. Someone has been in this engine before I think. I am thinking about lining up everything like you show and if my engine implodes. No big deal. I can get another one cheap. Almost all of the capacitors are leaking in the ecu. I am replacing those right now as well.
Thanks for any insight you can provide Kelvin.
Kelvin.
I would be timing it like normal , as thats how its meant to be timed. The tabs are for the camsensor triggers so dont time with those. Cheers , Another Kelvin.
I messed up my timing on my 1uz-fe interference engine trying to replace my water pump the belt jumped many times trying to remove the bolt for the crankshaft. The engine stopped rotating and got stuck now I don’t know how to get the timing back in place because I am guessing the valves are now hitting the pistons. Any advice need help
Bugger. What I do when guys have done this is drop all pistons to half way in bore, align cam marks, then bring pistons up. Then I fit belt and compression test as often valves are bent
My tensioner pulley, the part thats supposed to free wheel, is locked up when i tighten it down, is this normal or should i buy a replacement? Its the new one that came with the kit but it wont move what could be the issue? Threads are fine also
I suggest you check it over carefully as something isnt right. It should move freely. Cheers Kelvin
@@CartuneNZ thanks for the help
Does the timing belt run the water pump on these
Yes the waterpump is run by the timing belt. I have videos of the timing belt change and waterpump change. Cheers Kelvin
Mate, your help would be appreciated. I've fitted my belt a few times and after my two turns I'm a tooth off. Your belt slides on so easy, my belt doesn't. It's a genuine Toyota belt, with all Toyota genuine or OEM (Koyo, Aisin, NTN) parts. Any advice on what I need to to do to get it fitted? Cheers!
Do it again until your timing is correct.
@@CartuneNZ sounds good! Thanks mate. Appreciate the advice and the content.
Great video Kelvin! What brand of timing belt do you use please?
I only use genuine toyota timing belts, pulley, tensioner and waterpump, all genuine toyota.
Heyy! Thanks for your informative videos!!! Also, why do you put lock tight on every bolt, I've worked a bit on my Camry, doing the timing and I've never seen anyone put on as much thread lock as you. Is it Lexus procedure, Or you're own precaution? I'm doing the timing on it today and I'm a bit curious
I dont like stuff coming loose. If you take note when pulling most bolts out there is a little bit of loctite on them.
Thank you so much for the speedy reply. I'll be sure to grab some because why not! Better safe than sorry.
Heyy, I just threw a new belt on, everything was previously lined up, belt was tentioned, after spinning the engine by hand, L cam and R cam Mark's are 6 teeth past the marks while the crank is on tdc. Any suggestion to fix? I'm taking it apart again and refitting the belt
This is my engine. What is the part number for that Timing Belt (with the marks on it)?
What happens if my cams don’t line up ? When the crank mark is lined up , I already did a few set of rotations and the marking are still off
If the cams don't line up then the camtiming is wrong and I'd recommend correcting it
@@CartuneNZ how am I able to do that ? I tried spinning it by itself but it just swung back , and the crank pulley bolt I tried turning it but it doesn’t want to turn any more it just stuck , I was doin it without the belt not sure if I messed it up
Try watching this. ruclips.net/video/qL4NFeD1Bks/видео.html
@@CartuneNZ does the engine
Have to have oil when turning the crank pulley to set the timing ?
@@dabs7103 nope, they are fine provided its not started without oil
Hola! Tengo un 1uz non vvti y tengo que cambiar una junta que esta débil entonces es no se que kit de esos es que le cae al mío, y tengo que pedirlo por ebay, el que trae la correa y todo de una vez. necesito ayuda

Any advice if the belt doesn't have timing marks on it?
Its the same process however the fitter must rely on the marks on the backing plates. Personally I only use genuine belts so this isn't an issue I have to deal with.
@@CartuneNZ Thanks for the quick response Kelvin! I have been using the marks on the backing plates and I'm having an issue. I keep getting too much slack between the crankshaft pulley and the left cam pulley. I keep checking and rechecking the timing marks and they are correct but I'm still getting too much slack on the side without the tensioner. Any advice would be appreciated. Thanks for your time.
@@kameronclark515 have you found a solution to this? I've been having the same issue with a genuine Toyota Belt.
@@avianaviator1570 basically I could never get the timing marks to fully line up. The harmonic balancer mark seemed to be half a tooth off from what I could tell. That's the only way I could get the belt back on there without any slack. The 1uz-fe motor is non interference and the motor seemed to run fine. So basically I just lived with it. It is what it is. If it makes you feel better the crank pulley can only fit on the crank one way also. Hope this helps. Good luck 🤞!
@@kameronclark515 dude, that explains what's going on with my belt exactly lol. Seems half a tooth off perfectly. I'm wondering if it has something to do with my head's getting resurfaced. But considering yours is running just fine I'll just line it up with the marks on the belt and see how it runs. Thank you so very much for the input! It's a huge help!
Hi kelvin i have a 92 ls400 did a timing belt cam crank seals wtr pump tentioner pilleys and distributer rotors. I did everything exactly as you do. When i started the car it idles a little low and runs rich i give it gas let go it turns off
Doesn't sound ideal. First check is that the camtiming is perfect. then work on other stuff which could have been bumped , like the top coil plug being left off or poor connections. Confirm leads are on correctly. Confirm its running on all cylinders , check codes etc. Good luck. Cheers Kelvin
Did you ever find the issue my cars doing the same thing not sure if it’s off a tooth or something ran perfect before all
I got done was the timing belt. Runs but it cuts off at around 3500rpm
Next time install trigger wheel, how to position it correctly. Thanks
Its got a key on it. Only goes in one place. Only thing is people could fit it backwards but its pretty obvious which way it goes.
Is there a world where even though your timing lines are perfectly aligned that it still wouldn’t work?
Not one that I know of.
Detailed explanation in not even 8 mins
Some guys like a quickie , some want it for longer , so this is the quick one and I'm sure you could find my long one if you needed it. Cheers Kelvin
I don’t understand whenever i see a video of someone doing this they just slap it on when i try that i always end up with it 1 tooth off :( always ask my homie for help
I may have done it once or twice.
@@CartuneNZ im a mechanic myself just new to doing timing belts
En español lol
Done.
