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 camshaft timing belt every 60,000 miles.

TIRE INFLATION

Cold tire inflation pressures can be found on the tire information label located on the center console lid.

WHEEL TIGHTENING

Tighten wheel lug nuts to 72-87 ft. lbs. (98-118 N.m).

BATTERY SPECIFICATIONS

If battery is replaced, new battery should be of the same group number as shown on the original battery's label. All years and models use BCI group 24 batteries.

SPARE TIRE USAGE

Ensure correct lug nuts are used when the spare tire is fitted. DO NOT use lug nuts from alloy wheels on steel wheels.

RADIATOR CAP

When checking the coolant level, always allow the engine to cool before removing the radiator cap. If the radiator cap of a hot engine is removed, hot, high pressure coolant may be sprayed out and cause injury.

FUEL INJECTION LINES

On vehicles equipped with electronic fuel injection, the fuel filter and fuel lines are under high pressure even when the engine is off. Exercise care when servicing these items so as not to cause injury to yourself.
