CAMSHAFT TIMING BELT REPLACEMENT INFORMATION
CAUTION: Failure to replace a faulty camshaft timing belt may result
in serious engine damage.
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:
* Cracks Or Tears In Belt Surface
* Missing, Damaged, Cracked Or Rounded Teeth
* Oil Contamination
* Damaged Or Faulty Tensioners
* Incorrect Tension Adjustment
Replace camshaft timing belt at 60,000 mile intervals.
SEVERE & NORMAL SERVICE DEFINITIONS
NOTE: Use the Severe Service schedule if the vehicle to be serviced
is operated under ANY (one or more) of these conditions:
Service is recommended at mileage intervals based on vehicle
operation. Service schedules are based on the following primary
operating conditions.
Normal Service
* Driven More Than 10 Miles Daily
* No Operating Conditions From Severe Service Schedule
Severe Service (Unique Driving Conditions)
* Short Trips In Freezing Temperatures
* Towing Or Commercial Use
* Driving Off-Road Or In Salty Or Sandy Areas
