Hi folks next year the wife and I are going to travel around Australia, my 100 series 4.2 has 127.000 ks on the clock and by the time we are ready to go we will have over 130,000 ks plus on the clock, (we are heading off mid May) my owners manuel says change the timing belt at 150,000, do i change the belt before i go or wait until we return or do it while we are away.If we do it before we go how do i reset the dash light when 150,000 ks are on the clock, there are no black or clear plastic button or plugs on the speedo face to stick straightned paper clips into.I have the 1hz motor.
hope you can help ..Jaksun

Jaksun,
The timing belt is a major cost item if it goes on you as it usually takes a bit of other stuff with it.
I would talk to the service manager at a Toyota dealer and see what he suggests. I think the warning light may be reset when the belt is replaced.
The other option is to plan your trip to be a major centre at about the right time and get it done then.
Duncs.

I've been assured by a Toyota service manager that failure of the belt does no damage other than stopping the engine. I know that some makes do cause damage. Also if 150,000 is the prescribed time to replace, you'd have at least a 10% margin of safety so depends on how far past you'll be before you get home, but given the cost I'd be reluctant to replace it early.

AndrewX,
I can't believe that a tojo service manager would tell you that no damage would occur, other than stopping the engine. What happens to all the valves that are open, and the corresponding pistons crowns?
Damage does, and will occur, especially at highway speeds. Usually involves new head, plus valves. This going to be a lot more expensive than changing the t/belt a few clicks early.
Jacksun,
Change the belt now, and have one less thing to worry about on hols.
The belts are less than $100, and should be fitted for under $200. The 100 series belts must have been improved from 80 series, to extend the interval to 150K kms. Of course you could always plan to get it changed at tojo service centre, while getting oil change done, during your trip.
Enjoy the trip,
Hooroo...

Bob Y,
Many engines have recesses in the piston crowns to accomodate the valves should a timing belt break. My Prado has the 1KZ-TE engine and a Subaru EA82 for example have the recesses. Not absolutely sure about the 1HZ in question.
And if it were me, I'd get the timing belt replaced before going away. Too much hassle otherwise.

150,000 is correct for a 5/98 onwards 1HZ
On a 100 series the timing belt is reset by a procedure that can be carried out by any toyota dealer
Without this procedure you can not reset the light yourself unlike the early model toyotas
It is outlined in a service bulletin that toyota issuied to dealers as it was not in the 100 series workshop manual when released
If the belt is replaced before the speedo brings the light on at 150,000 klms the light can be reset to come on a 150,000 klms after the present odometer reading
It is not a difficult or expensive job to replace a 1HZ belt & if you replace it before the specified time it will be one less thing to do while you are away
Dealers will not normally give out timing belt reset procedures to the public
