off the vehicle. The "on the vehicle" type, however,
is the more desirable in that all rolling components
lrotating 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 operator's manual for Information regarding
the proper tire selection. 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)
Your motor home is equipped with either a 454 CID
(Chevrolet chassis) or 460 CID(Ford or .Oshkosh
chassis) gasoline engine. Refer to the chassis
operator's manual for specific fuel recommendations.
Engine Oils
Refer to the chassis operator's mantlal and vehicle
maintenance schedule for the oil type, viscosity and
change intervals recommended for the operating con-
ditions encountered.
ENGINE FUEL SYSTEMS
Fuel and Air Filters
Inspect and replace fuel and air filters acc;.ording
to the chassis manufacturer's Maintenance Schedule.
Inspect and maintain the fuel and emission con-
trol systems in accordance with the cihassis' manufac-
turer's Maintenance Schedule. Check fuel lines for
signs of leakage, damage or deterioration.nghten
- 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 SOOr.ler if
it is dirty. Check
hos~s
regularly for signs of damage
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 Iiniflg of the hose is also
a reason for replacement. Such particles can clog the
cooling system, reducing Its efficiency.
Wash the radiator cap with clean water and
presstire'checkevery 12 months,
Coolant Level
The coolant level can be seen in the "see through"
recovery bottle while the engine Is at normal operating
temperature. The radiator
CI)P
need not normally be
removed,
The coolant level should be at the "Full Cold" mark
. when the system is cool or at ambient temperature.
After the vehicle has been driven sufficiently to ob-
.tain l1ormaloperating temperatures, the level should
be above the "Full Cold" mark,
Remove the radiator cap periodically to observe
coolant level in-the radiator.
WARNING':'TO:HELPAVOID niEDANGER 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, Be sure the recovery bottle is at
its appropriate mark when checking,
Regardless of whether freezing temperatures are
expected or not, maintain cooling system protection
to at least -34 OF, to provide adequate corrosion pro-
tectionand loss of coolant from boiling,
When

area~
where temperatures lower than
-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 notrecommended for your engine at a ny time.
They
will
not provide proper protection against
corrosion,
• Additives in addition to a good quality ethylene
glycol-base antifreeze meeting the chassis
manufacturer's specification are not required or
recommended, Many of the claims for additives
are associated with better heat transfer or cool·
ing, but these claims are not supported by test
data, In some instances, the ingredients may be
incompatible with the recommended coolant, Also,
when used alone with water as is sometimes sug-
gested, the additive may not provide the cor-
