REPAIR DRIVE BELT
A single 'serpentine drive belt' is introduced for 1995
model year. This belt drives the water pump and all
the ancilliaries. It is essential that the belt is fitted
exactly as shown in illustrations RR3956 and RR3957.
It should also be noted that the water pump/viscous
fan is driven in a counter clockwise direction.
A drive belt tensioner automatically tensions the drive
belt, eliminating the need for tensioning individual
drive belts. Turning the tensioner pulley in a clockwise
direction will release drive belt tension.
Under normal highway use the belt must be changed
at 120,000 kilometres, 75,000 miles or five years
whichever occurs first.
The drive belt must be examined at every service and
replaced if necessary.
Off road driving
Regular examination of the drive belt is essential if the
vehicle is used off road. The vehicle driver should be
requested to identify the type of mileage the vehicle
has covered.
After every off road session the owner should inspect
the belt for cuts and possible damage caused by
stones. If belt has jumped, reposition belt correctly. A
new belt must be fitted at the next service or before,
dependant on the type of damage sustained.
Fan cowl
To ensure easy access to the drive belt the top portion
of the fan cowl is detachable.
Check condition
Check condition of drive belt. Renew a belt that shows
signs of wear, splitting or oil contamination.DRIVE BELT RENEW
