CAMSHAFT TIMING BELT
Replace camshaft timing belt at 60,000 mile intervals.
The condition of camshaft drive belts should always be checked on vehicles which have more than 50,000
miles. Although some manufacturers do not recommend belt replacement at a specified mileage, others require
it at 60,000-100,000 miles. A camshaft drive belt failure may cause extensive damage to internal engine
components on most engines, although some designs do not allow piston-to-valve contact. These designs are
often called "Free Wheeling".
Many manufacturers changed their maintenance and warranty schedules in the mid-1980's to reflect timing belt
inspection and/or replacement at 50,000-60,000 miles. Most service interval schedules in this manual reflect
these changes.
Belts or components should be inspected and replaced if any of the following conditions exist: NOTE: Use the Severe Service schedule if the vehicle to be serviced is operated under
ANY (one or more) of these conditions:
CAUTION: Failure to replace a faulty camshaft timing belt may result in serious
engine damage.
