off the vehicle. The "on the vehicle" type, however,
is the more desirable in that all rolling components
(rotating brake components, bearings, seals, etc.) are
included in the balancing process. Because of the
specialized equipment required, wheel and tire balan-
cing should be performed by a qualified service shop.
Tire Replacement
When replacing tires, be sure to consult your
chassis ope.rator's manual for information regarding
the proper lire sel.ection. Use of the incorrect size or
type tire may affect load carrying capacity, ride, handl-
ing, speedometer/odometer calibration, vehicle ground
clearance, and tire clearance to the body and chassis.
If replacing only a single tire, it should be paired on
the same axle with the least worn tire of the others.
WARNING: DO NOT MIX DIFFERENT TYPES OF
TIRES ON THE SAME VEHICLE SUCH AS RA-
DIAL, BIAS, AND BIAS-BELTED TIRES EXCEPT
IN EMERGENCIES, BECAUSE VEHICLE HANDL-
ING AND TIRE LIFE MAY BE SERIOUSLY AF-
FECTED AND,MAY RESULT IN LOSS OF CON-
TROL OR TIRE FAILURE.
ENGINE (Refer to Chassis Operator's Manual)
Refer to the chassis operator's manual for specific
fuel recommendations.
Engine' Oils
Refer to the chassis operator's manual and vehicle
maintenance schedule for the oil type, viscosity and
change intervals recommended for the operating con-
dition$.lilnc6untered.
ENGINE FUEL SYSTEMS
Fuel and Air Filters
Inspect and replace fuel and air filters according
to the chassis manufacturer's Maintenance Schedule.
Inspect and maintain the fuel and emission con-
trol systems in accordance with the chassis manufac·
turer's Maintenance Schedule. Check fuel lines for
signs of leakage, damage or deterioration. Tighten
clamps if they are loose. Replace filters in the fuel
line and the evaporative control system at the recom-
mended intervals.
Air Cleaner Element Replacement
Replace the air cleaner element according to the
chassis manufacturer's maintenance schedule.
COOLING SYSTEM
Maintenance and Inspection
Check the coolant level, appearance, and strength
periodically. Drain and replace at the intervals recom-
mended in the Maintenance Schedule, or sooner if
it is dirty. Check hoses regularly for signs of damage
39
or deterioration, and tighten hose clamps if necessary.
Check hoses for cuts or abrasion damage. If the
hoses have become hard and brittle and show signs
of cracking as a result of engine heat, replace them.
Replace hoses if they are soft and spongy, or swollen
as a result of exposure to oil and grease. Any flaking
or deterioration of the inner lining of·,.the hose is also
a reason for replacement. Such particles can clog the
cooling system, reducing its efficiency.
'5;
Wash the radiator cap with clean water and
pressure-check every 12 months.
Coolant Level
Remove the radiator cap periodically to observe
coolant level in the radiator.
WARNING: TO HELP AVOID THE DANGER OF
BEING BURNED, DO NOT REMOVE THE RADI-
ATOR CAP WHILE THE ENGINE AND RADIATOR
ARE STILL HOT; SCALDING FLUID AND STEAM
CAN BE BLOWN OUT UNDER PRESSURE IF THE
CAP IS TAKEN OFF TOO SOON.
Maintain coolant levels in the radiator to the top
of the filler neck.
Regardless of whether freezing. t.emperaturesartjl
expected or riot, maintain cooling system protection
to at least -34 ° F, to provide adequate corrosion pro;
tection and loss of coolant from boiling. ."
When adding solution due to loss of coolantAot
any reason or in areas where temperatures lower tha~
-34°F occur, use a sufficient amount of an ethylene
glycol base antifreeze that meets the chassis
manufacturer's specification.
• Alcohol or methanol base antifreeze, or plain water,
are not recommended for your engine at any time.
They will not provide proper protection against
corrosion.
• Additives in addition to a. good quality ethylene
glycol-base antifreeze meeting the chassis manufac-
turer's specification are not required or recommend-
ed. Many of the claims for additives are associated
with better heat transfer or cooling, but these claims
are not supported by test data. In some instances,
the ingredients may be incompatible with the recom-
mended coolant. Also, when used alone with water
as is sometimes suggested, the additive may not pro-
vide the corrosion protection given by the recom-
mended coolant solution.
Flushing Cooling System
Various methods and equipment may be used to
perform this service. If special equipment such as a
back flusher is used, follow equipment manufacturer's
instructions.
