I have a 2003 gs430 w/51k miles on it. Took to dealer to get ATF fluid changed and he recommended the timing belt be changed out @ 75k or 7 years. Do I really need to get this done now? Is the belt good for 10 years?

I know most 4g63's are 5yrs or 60k, theres no way I'd let a timing belt roll for ten years.

I work at a Lexus dealership as an advisor and I tell people 7 years or 90k. I wouldn't let it roll any longer on time. You just never know when that rubber belt will go.

Change that timing belt right away before it breaks and causes damage to other things.
90k or 7years which ever comes 1st. There's a reason why they tell you to change it at that interval. Do it for the piece of mind.
