SEVERE & NORMAL SERVICE DEFINITIONS

Service is recommended at mileage intervals based on vehicle operation and engine type. Service schedules are based on the following primary operating conditions

Normal Service

1. Driven More Than 10 Miles Daily
2. No Operating Conditions From Severe Service Schedule

Severe Service (Unique Driving Conditions)

1. Towing A Trailer, Using A Camper Or Car Top Carrier
2. Repeated Short Trips Less Than 5 Miles When Temperatures Are Below Freezing
3. Extensive Idling Conditions (Taxi Or Delivery Type Service)
4. Operating On Dusty, Rough, Muddy Or Salt Spread Roads

CAMSHAFT TIMING BELT

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

1. Cracks Or Tears In Belt Surface
2. Missing, Damaged, Cracked Or Rounded Teeth
3. Oil Contamination
4. Damaged Or Faulty Tensioners
5. Incorrect Tension Adjustment

Replace the camshaft timing belt every 72 months or 60,000 miles if the vehicle is operated under Severe Service conditions such as frequent idling or extensive long distance driving at low speeds (taxi, police or door-to-door delivery).
