Thanks OBP. The Aisin kit comes with Mitsuboshi which is the OEM. I replaced my serpentine with GATES back in 2010. It still looks good.
Yes I want to see the OEM belt, but yours is young, they will look almost new.
See you later in the month.

First off,thank you very much for the .PDFs at the beginning of this thread!
I lost my digital workshop manual set late last year when my last laptop's HDD crashed and as I'm doing the belt,tensioners,idlers & pump on my LS430 this weekend,the info is invaluable!
One quick question for you all: Have any of you changed the oil seals?
No-one's mentioned it so far and I have generally always done these as well when doing a job like this,so you know you never need to open it up again...
The cam seals are several hours work to do as thw whole cam has to come out and be pulled apart to get them out,but the crank is straight forward.
Mine look okay so far,so they're staying this time around,but what sort of mileage have people seen them fail at?
My car has 146k km on it,and was running an original belt until a few hours ago...
I plan to pull the top covers every second service and inspect the oil seals from here on out until they start to leak.
This is an interesting topic. I went back-and-forth on whether to change seals when I did my timing belt. They looked good and weren't leaking (of course). I read a few comments from Lexus/Toyota techs who claimed crank/cam seal failure was rare in Toyota/Lexus. Also, I've owned a lot of cars in the past 40 years, and take many of them to high mileage - gas, diesel, turbo charged, 4's, 6's, 8's - and I've never had a crank or cam seal failure. Maybe I'm lucky, or fussy, or both.
So I passed on changing the seals. So far, so good (that was almost 60K miles ago on my '02)
I changed all the front end seals on my SC430 engine last year, and included the power steering pump too. Seems like the opportune time to do it,, and yes I have had them fail on other Lexi I've owned the crankshaft seal failure being the most annoying and costly one.
I'd even chrome my wife, if she'd let me.
