belt tension can cause belt slippage and failure. Belts
should be inspected for evidence of cuts, cracks, glazing,
or frayed cords and replaced if there is indication of
damage which could result in belt failure. Low generator
belt tension can cause battery failure. Also check belt
routing to make sure there is no interference between the
belts and other engine components.
Spark Plugs
Spark plugs must fire properly to assure proper engine
performance and emission control. The plugs installed in
your vehicle should operate satisfactorily in normal
service for the mileage indicated in the Maintenance
Chart. New plugs should be installed at this mileage. The
entire set should be replaced if there is any malfunction
due to a faulty spark plug. Refer to Fluids, Lubricants
and Genuine Parts for the proper type of spark plug for
your vehicle.
CAUTION!
When replacing plugs, do not overtighten. You could
damage them and cause them to leak.

in the case of engine backfire. Do not remove the air
cleaner unless such removal is necessary for repair or
maintenance. Make sure that no one is near the
engine compartment before starting the vehicle with
the air cleaner removed. Failure to do so can result in
serious personal injury.
