Drive Belts — Check Condition and Tension
Belt tension is controlled by means of an automatic
tensioner. Therefore, no belt tension adjustments are
required. However, belt and belt tensioner condition
should be inspected periodically and replaced if re-
quired. Improper belt tension can cause belt slippage and
failure. Low generator belt tension can cause battery
failure.
Inspect belts for evidence of cuts, cracks, glazing, or
frayed cords and replaced if there is indication of dam-
age, which could result in belt failure. Also, check belt
routing to make sure there is no interference between the
belts and other engine components. See your authorized
dealer for service.
Spark Plugs
Spark plugs must fire properly to assure engine perfor-
mance and emission control. New plugs should be in-
stalled at the specified mileage. The entire set should be
replaced if there is any malfunction due to a faulty spark
plug. Malfunctioning spark plugs can damage the cata-
lytic converter. Refer to “Fluids, Lubricants, and Genuine
Parts” in this section for the proper type of spark plug for
use in your vehicle.
Engine Air Cleaner Filter
Refer to the “Maintenance Schedule” in Section 8 of this
manual for engine air cleaner filter maintenance inter-
vals.
NOTE:
Be sure to follow the “dusty or off-road condi-
tions” maintenance interval if applicable.
