MAINTENANCE SERVICE INFORMATION

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)

* Extended Idling Or Low Speed Operation

* Frequent Short Trips Of Less Than 7 Miles

* Extended Operation In Dusty Or Sandy Conditions

* Trailer Towing Operations

* Driving In Mountainous Conditions

CAMSHAFT TIMING BELT

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

Volvo recommends replacement of the camshaft timing belt at

the following intervals:
