CARE AND MAINTENANCE
ROUTINE INSPECTION
This inspection should be performed every
working day.
WITH ENGINE STOPPED
Inspect hoses for leaks. Carefully inspect all
fittings, clamps and ties. To prevent chafing,
make sure hoses are not touching shafts,
couplings, heated surfaces, sharp edges or other
parts. Since hose clamps and ties can vibrate
loose or fail over time, inspect frequently and
tighten or replace as necessary.
Check for loose nuts and bolts. Visually inspect
safety of compartment door latches. Test
operation of all exterior lights.
Leaks
Check for leaks under vehicle and in
compartments.
Correct leaking hoses immediately. Failure to
correct leaks can cause severe damage to the
equipment, as well as increase operating costs
due to lost fluids. Treat fuel and oil leaks as an
immediate fire hazard.
Warning: Personal injury and property damage
may result from fire caused by leaking
flammable fluids.
Hose Service Life
Hoses have a limited service life. Thoroughly
inspect hoses annually. Look for surface
damage or indications of twisted, worn, crimped,
cracked or leaking lines. Replace damaged
hoses immediately.
Hoses should be replaced during major overhaul
or after a maximum of seven years service. Be
certain replacement hoses match the original
equipment manufacturer's specifications.
Wheels And Tires
Check for loose wheel nuts. Both aluminum
alloy and steel wheel nuts should be tightened to
450 to 500 foot-pounds (610 to 680 N.m.)
torque.
Tire Pressure
Keep the tires inflated to the recommended
inflation pressure to prolong tire life and for
safety.
Note: Recommended tire inflation pressures are
given in the "Coach Final Record", placed in the
technical publications package supplied with the
vehicle. The cold tire inflation pressures are on
the Department of Transport certification plate
located on the L.H. console besides the driver’s
seat. When special tires are installed by Prevost
on a new vehicle, a special tire inflation chart is
added next to the certification plate.
Warning: Do not exceed maximum inflation
pressure. Incorrect tire pressure increases tire
wear and could lead to loss of driving control
because of reduced road handling. Check tire
pressure regularly.
Warning: If replacement tires are different from
those described on the certification plate,
pressure must be adjusted as requested in the
Tire and Rim Association Manual.
Doors
Close all exterior doors and windows. Check for
good tightness and fit.
Tools And Spares
Make sure the vehicle is equipped with a wheel
nut wrench, door keys, spare belts, reflectors
and jack.
Air System
To drain water from air and accessory tanks,
open drain cocks. Close drains when
completed. Refer to heading "Air Tank Purge" in
this chapter.
Water Separator
To drain water separator, open drain valve.
Close drain valve after draining.
Coolant Level
Check coolant level. Coolant level is correct
when visible in the filler neck of the surge tank.
If coolant level is low, fill system with 50-50
coolant-water mixture. Refer to the vehicle
"Maintenance Manual", section 05 for more
information.
Warning: Hot engine coolant is under
pressure. Do not attempt to open the coolant
filler cap when the engine is hot. Allow engine to
cool before adding coolant.
