Ls430/Celsior timing belt interval

[GEN]

I have had a 1998 LS400 for over a decade and I am now on my third timing belt and second water pump and tensioner.  I would be grateful if a Ls430 or Celsior owner could let me know what are the mileage/time intervals for changing the timing belt on that car.

Every 60000 miles I think it was. On the ls430 it's every 100000 miles or 10 years, which ever comes first 

[BigBoomer]

LS430 (2004-2006) is every 90,000 miles or 72 months (6 years) according to the manuals.
Mine was done at 75k miles so I plan on getting it done again at 150k miles.

with my Ls400 I followed the USA syndrome of 100k miles / 10 years for cambelt waterpump stuff

I changed mine last May at 100500 miles and 11 years ......  everything looked quite good, no fraying belt etc, pulleys a bit tired though I think

I did read somewhere that the zap point of " snap " on the cambelt is @ 150k miles

It's exactly the same set-up in the UK as the USA so don't understand why UK should be different

I remember reading that the nature of driving in USA is longer distances, therefore less stop/start. This was given as the reason the service intervals etc. are, different. Not my opinion , just something I read. Roger

Intervals are different in US and even Europe compared to the UK. Mainly down to higher speeds, fast acceleration, and more stop/start in UK/Europe but some of it is just marketing - what is the norm in each country and what the competition offer.

US may have longer intervals on a timing belt but have an oil change every 5-6k miles which is the norm there.

but why should that be different anywhere in the world .....  it's individual's driving style surely ?  NOT just, it's the USA and the climates different, the roads are better ( or worse )

I think it's just taking the p-ss by the marketing guys wherever

My experience above, many styles of driving over 10 years and 100k miles  including mine with this last change last May since I bought the car in June 2011 at 123k miles  ..... now on 217k miles

Thank you everyone.  I thought as much but someone (I shall not identify) was telling me that it was done on mileage only (at 60000 miles) and the car has only covered 50000 but is a 2001!  so the original timing belt! 

[Malc]

18 years is sure a long time on an original belt  !

are you certain it's original ?

my second Ls400, my 1994  Mk2 which I bought in December 2007 at 8542 miles had the original cambelt changed at 3400 miles at 10 years old 

now that must have been like brand new surely

Not sure that it's original but I'm told by the seller that it doesn't need one as it hasn't reached 60000 miles and it's done on mileage and not time!  I was pretty sure that the guy is wrong but wanted to check.  Given the replies I've had here the best interpretation I can put on what I've been told is that he doesn't know.  So if I decided to buy I guess I'd have 2 jobs to be done immediately : radiator to avoid transmission problems and the full timing belt, water pump, tensioner.. Then there's the air suspension.... 

[RgrWynne]

Do those items first, which in any event will give peace of mind. Don’t worry about the air suspension, most  do not fail and just enjoy !!!!!!!!

US have lower speed limits and less aggressive driving style (in general terms).

The series I RX for example had a transmission oil cooler fitted as standard in Europe, not in the US. Lexus' reason was higher driving speeds so it isn't just service intervals that are changed between countries.
