It appears that 1998 (my year) is the only goofy year. For 98 the
federal spec says replace the timing belt @ 60k, while the Cal spec
says 105K. Is this a typo or does the federal car use a cheaper belt?
Common replies are that California law requires 100k mile belt life.
The manufacturers responded by printing a maintenance schedule showing
that the belt should be inspected a regular intervals and replacement
at +100k miles even though it is the same belt.
The dealer will then recommend replacement at 60k miles when it is
inspected.
In reality your belt may last 100k miles without needing replacement.
If you gamble, at least know the odds and the payout. Breaking a
belt on a non-interference engine usually costs a tow plus replacement.
Breaking a belt on an interference engine can be very costly.
If you're doing other work which will make timing belt replacement
less expensive before the recommended replacement period has
expired, that might be a good bet.
I'm currently running a belt at 135k kms with a normal life of over
160k kms. The replacement recommendation is 100k kms, but 160k kms
in California. Since engine is non-interference, I will replace it
either when other work needs doing, or at 160k kms as required.
