Mitsubishi Montero (1991+). Manual - part 176

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.
