replacing timing belt in 03 ultra
a little help from all you "lexus " guys out there.;...........I currently have a 03 LS Ultra with 54K miles on it. I know the manual calls for the timing belt to be replaced at 90K miles OR 7 years. My question is since mine has only 54K miles but is older that 7 years.......which is the more important one in trying to figure out when to get this done? Thanks in advance. RJ

To be extra-safe you can replace it. But you may (and probably will) find, that current state of the belt is 'as new' at this mileage. They last over 100k miles.

It is a rubber belt so and so like any item made of rubber it does age over time even with low miles. I personally think 7 years is very conservative but a lot depends on the condition of the car in general and how it is driven and stored. My LS is an 06 and it is not gonna have 90k miles on it anytime soon. My car has 51k on it right now and I drive about 6k miles a year. It is very gently driven and garaged all the time so given my specific situation I am likely going to wait till car is 10 years old to change TB. But even more likely is that I will sell the car at 10 yo with approx 70k miles on it (approx June 2016) and let someone else decide what to do about the TB.

I agree,,,my sc400 is 20 years old, and its on the original belt still, ,and I drive that thing , I mean I ABUSE that thing like u wouldn't believe, 25-30 000 kilometres a year of very hard driving ,, winter and all.
I truly think 99% of timing belts would last to 200 000+ miles, but its not worth it , id say change it every 100k and I think that's being reasonable.
I think when I do mine I will change the tensioner and all the pulleys, from what I heard they are usually the reason for the belt breaking.

If one was to change out the tensioner ....then in order to do this, one would have to spend the same in labor to get to this as it would be involved in labor to get to the Timing bely---Right?? Sp, if that is true, then one would be foolish to spend all that money to change tensioner/pulleys and not change the timing belt while you have everything pulled. The timing belt itself is not that much....it is the labor to get to that thing.RJ

Yes. Basically to access tb+pulleys+tensioner+waterpump you need to drain coolant, remove radiator, remove aux belt, remove aux belt tensioner and pulley, take tb covers off. So, yes, same amount of work.

Here in the States they do NOT remove the radiator to replace the timing belt.

So it makes no difference----if the tensioner is the real thing to worry about----the money involved to "fix" the real culprit is the same ....so you might as well change the tb while you have everything pulled....that is the point I am trying to make....it makes no difference if the tb or ensioner is to blame.....it costs are the same.

replaced my TB, tensioners and leaking vvt-i tube assy... took whole day, job not for faint hearted.
i have no idea, rookie, how can you access the tb without removing the rad and draining coolant. it's just impossible.
