Toyota recommends replacing the timing belt at the 90,000 mile service, or when it ha been in service for 6 years.
The engine is an interference engine, so don't push it too long after the recommended interval.
This is more of a mileage/time interval, so the schedule A and B are not relevant to this repair.
Awesome answere,,,,Question for you,, Looking at at the engine,,is that the timing belt (outside of) the engine? on the left hand side, on top looks like there is a belt ro something on the left side easy to get that it? how easy would it be to replace, I am a mechanic,, (not professionally-though like most of you) thx
