Engine Maintenance
Introduction and important maintenance
requirements.
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
Engine cleaning precautions.
When cleaning the engine, follow the
instructions from the vehicle manufacturer
operator's manual and observe all
environmental protection regulations.
CAUTION
DO NOT direct water onto electrical
components, plug connectors, seals or
flexible hoses on the engine. Water
may enter the part causing electrical
damage or contaminating the engine
oil. To prevent damage to engine com-
ponents, keep the water moving at all
times while cleaning the engine. Fail-
ure to comply may result in equipment
damage.
