REPAIR DRIVE BELT INFORMATION
A single 'serpentine drive belt' drives all the
ancilliaries bar the air conditioning compressor, which
has a separate drive belt. It is essential that the belts
are fitted exactly as shown. It should also be noted
that the water pump/viscous fan is driven in a
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 160,000 kilometres, 96,000 miles or eight 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.
