Drive Belt ± Check Condition
At the mileage shown in the maintenance schedules,
check the drive belt for condition.
Inspect the drive belt for evidence of cuts, cracks, or
glazing and replace belt if any sign of damage which
could result in belt failure.
The belt is self-tensioning and will not need adjustment.
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. Refer to the Engine data Label located under the
hood for the proper type of spark plug for use in your
vehicle.
Catalytic Converter
The catalytic converter requires the use of unleaded fuel
only. Leaded gasoline will destroy the effectiveness of the
catalyst as an emission control device.
Under normal operating conditions, the catalytic con-
verter will not require maintenance. However, it is im-
portant to keep the engine properly tuned to assure
proper catalyst operation and prevent possible catalyst
damage.
