hello all, my friends mom has a (10year old) 2002 SC430 closing in on the 140,000 miles mark,
she had the Timing Belt changed when the car had 75K miles on it. Its been running flawless
ever since. Should we change again? Its a daily driven car, but babied.

What is/are the "most" recommeded Service for a 140K miles 2002 SC430.
We checked the phamplet on the Milage Daily Services on what to do, but can anyone
chime in on the "most recommeded" service we should do on a 2002 140K miles car?
I know we are probably going to pay over $1,000 for the recommend service, which is fine,
better safe then sorry!

Thank you much for the input guys.

p.s.
please list as much as you can
She wants the car to last forever

Yes

For future reference, it's available on Lexus's website. But the last major service you missed was 135,000.

I would say in a short answer that it's not needed yet. 65k since last timing belt change. I would do the services LiquidSC posted above and do the timing belt in another 25k or so...at 90k since last timing belt.

.....how about the "spark plugs" changed? when do you guys have to change them out?

They are supposed to last to 120k per the dealer and recommended service or . I just did mine at 39k and 7 years. I've found that over the years my garage queens tend to need plugs more frequently mainly due to the lack of spark burning on the plugs causing more corrosion over time versus a plug that burning and hot all the time like a daily driver. Just my opinion with garage queens and third cars/sports cars. Plus...it couldn't hurt to do them earlier IMO. I upgraded to NGK Laser Iridium plugs.

I just picked up a set of eight Iridium Spark Plugs for $71 at Advance Auto, item number 3297. I'm not sure what they cost at the dealer.

You have the NGK Iridiums right? I got the NGK Laser Iridiums for right around the same price ($68) and love them! I definitely noticed a difference. Crisp acceleration, no hesitation whatsoever and she just wants more gas all the time!

Let us know what you think after you install, Jason
