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 105,000 mile intervals if vehicle is operated under normal service conditions, and at 102,000 mile intervals if operated under severe service conditions.
SPARK PLUG REPLACEMENT INTERVAL INFORMATION
Spark plug replacement intervals, if given, are for Original Equipment Manufacturer (OEM) installed or specified plugs. If vehicle is equipped with platinum type or other non-OEM type spark plugs, follow replacement interval specified by spark plug manufacturer.
