Belts should be inspected for evidence of cuts, cracks, or
glazing, and replaced if there is indication of damage
which could result in belt failure. If adjustment is re-
quired, the belts must be adjusted according to the
specifications and procedures described in the Service
Manual. Low generator belt tension can cause battery
failure. A special tool is required to properly measure
tension and to restore belt tension to factory specifica-
tions.
Also check belt routing to make sure there is no interfer-
ence between the belts and other engine components.
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. For proper type of replacement spark
plugs, refer to the “ Vehicle Emission Control Informa-
tion ” label in the engine compartment.

ditions, the filter element should be inspected periodi-
cally and replaced if necessary at the intervals shown on
