Maintenance
Requirements
Engine Maintenance
PACCAR recommends that the engine be
maintained according to the maintenance
schedule in this section.
If the engine is operating in ambient
temperatures below 0°F (-18°C) or above
100°F (38°C), perform maintenance at
shorter intervals. Shorter maintenance
intervals are also required if the engine is
operated in a dusty environment or if
frequent stops are made.
Some of these maintenance procedures
require special tools or must be completed
by qualified personnel. Contact your local
PACCAR authorized repair location for
detailed information.
If your engine is equipped with a
component or accessory not manufactured
by PACCAR Inc, refer to the component
manufacturer's maintenance
recommendations.
WARNING
Never idle your vehicle for prolonged
periods of time if you sense that ex-
haust fumes are entering the cab. In-
vestigate the cause of the fumes and
correct it as soon as possible. If the
vehicle must be driven under these
conditions, drive only with the windows
open. Failure to repair the source of
the exhaust fumes may result in death,
personal injury, equipment or property
damage.
WARNING
Exhaust fumes from the engine con-
tain carbon monoxide, a colorless and
odorless gas. DO NOT breathe the en-
gine exhaust gas. A poorly maintained,
damaged or corroded exhaust system
can allow carbon monoxide to enter
the cab. Entry of carbon monoxide into
the cab is also possible from other ve-
hicles nearby. Failure to properly main-
tain your vehicle could cause carbon
monoxide to enter the cab, resulting in
death or personal injury.
Cleaning the Engine
You must clean the undercarriage, engine
compartment, and engine as needed, but
at least annually. Cleaning removes road
salt and debris that can be corrosive or
otherwise harmful to the electrical system.
Failure to properly clean the undercarriage
of the truck can increase the risk of an
electrical fire. When cleaning the engine,
follow the instructions from the vehicle
manufacturer's operator's manual and
observe all environmental protection
regulations.
CAUTION
Do not direct high pressure water onto
electrical components, plug connec-
tors, seals or flexible hoses on the en-
gine. Failure to comply can accelerate
corrosion and degrade electrical com-
ponent which may cause a fire or
equipment damage.
