5 VEHICLE MAINTENANCE REQUIREMENTS

F060D01A-AAT
o Fuel Lines, Fuel Hoses and Con-
nections
Check the fuel lines, fuel hoses and con-
nections for leakage and damage. Have a
trained technician replace any damaged
or leaking parts immediately.
F060B01NF-GAT
o Drive Belts
Inspect all drive belts for evidence of cuts,
cracks, excessive wear or oil saturation
and replace if necessary. Drive belts should
be checked periodically for proper tension.
F060M01A-AAT
o Engine Oil and Filter
The engine oil and filter should be changed
at the intervals specified in the
maintenance schedule. If the car is being
driven in severe conditions, more frequent
oil and filter changes are required.
F060C01A-AAT
o Fuel Filter
A clogged filter can limit the speed at which
the vehicle may be driven, damage the
emission system and cause hard starting.
If an excessive amount of foreign matter
accumulates in the fuel tank, the filter may
require replacement more frequently.
After installing a new filter, run the engine
for several minutes, and check for leaks at
the connections. Fuel filters should be
installed by trained technicians.
F060F01A-AAT
o Vacuum, Crankcase Ventilation
Hoses
Inspect the surface of hoses for evidence
of heat and/or mechanical damage. Hard
and brittle rubber, cracking, tears, cuts,
abrasions, and excessive swelling indicate
deterioration. Particular attention should
be paid to examine those hose surfaces
nearest to high heat sources, such as the
exhaust manifold.
Inspect the hose routing to assure that the
hoses do not come in contact with any heat
source, sharp edges or moving component
which might cause heat damage or
mechanical wear. Inspect all hose
connections, such as clamps and
couplings, to make sure they are secure,
and that no leaks are present. Hoses should
be replaced immediately if there is any
evidence of deterioration or damage.
