you should be concerned about the timing belt, water pump, tensioner, idler pulley etc...and have them replace the serpentine belt since they removed it to do the TB job.
you can always ask your local Lexus or Toyota dealer.

Think about it like this. Would you trust 10 year old tires on your car, even if the had low miles? Now a 10 year old rubber belt, that if it breaks you are buying a new engine. Rubber degrades not just from use, but time also.

Serpentine belt
Has anyone ever known or heard of someone whose timing belt on an SC430 or other Toyota 4.3L actually broke?
It would be interesting to know the age/mileage of a real life timing belt failure example.
I believe the rubber is a synthetic rubber and I would like to think the Toyota engineers built in a margin of safety over and above the recommended service interval.
There are probably many factors such as driving style, weather fluctuations, etc. that would influence the life cycle of a belt.
And I totally agree that its a good investment rather than trying to rebuild or replace your engine (I did mine at 72k miles/ 13 years and it looked just fine).
The serpentine belt is very easy to visually inspect for cracks and missing teeth.
I'm not even sure how you would easily remove a cam cover to see the timing belt and cycle it so it could be inspected?

Yes, plenty of talk about that. Read post #15.

I just done mine at 65k miles of an 07 for less than $750 that included transmission fluid serviced and Mobil 1 oil changed. Post # 13 and 16.

the link is in my previous post.
just curious, you asked about changing the serpentine belt, is there any difference between that belt and the timing belt?
