submerged in water.
Timing Chain
If you use your vehicle extensively at a race
track or at high rpm, it is possible to exceed
the service life of the engine timing chain.
A wrench indicator light will illuminate
when it is time for you to replace your
chain. See an authorized dealer.
California Fuel Filter Replacement
If you register your vehicle in California, the
California Air Resources Board has
determined that the failure to perform this
maintenance item does not nullify the
emission warranty or limit recall liability
before the completion of your vehicle's
useful life. Ford Motor Company, however,
urges you to have all recommended
maintenance services performed at the
specified intervals and to record all vehicle
service.
