•
If operating in arctic temperatures of –20°F (–29°C) or lower, consult
your truck dealer for information about special cold weather
equipment and precautions.
Note:
Idling in cold weather will not heat the engine to its normal
operating temperature. Long periods of idling in cold weather can cause
a buildup of heavy deposits of carbon and rust on valve stems causing
them to stick, which in turn, can cause valvetrain damage.
The following cold weather idling guidelines must be followed:
•
Avoid idling the engine for more than 10 minutes at a time.
•
Use a minimum of 42 Cetane Diesel fuel or use Cetane Index
improvers from a reputable manufacturer.
•
Maintain the engine cooling system properly.
•
Do not shut the engine down after an extensive idling period (10
minutes or more). Drive the vehicle under load for several miles at
normal operating temperatures to burn off any accumulated carbon
and varnish.
Hot weather operation
•
Keep the engine cooling system filled with a clean, permanent coolant
solution to protect against damage from overheating.
•
Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•
Keep external surfaces of the engine, radiator, charge air cooler, A/C
condenser and accessories clean to avoid dirt build-up.
Restarting after running out of fuel
The fuel system may need to be purged of air, refer to
Running out of
fuel
in the
Maintenance and Specifications
chapter.
GENERAL OPERATING INSTRUCTIONS
•
Accelerate smoothly and evenly; rapid acceleration increases fuel
consumption without increasing engine performance.
•
When approaching a hill, depress the accelerator smoothly to start the
incline at full power, then shift down as needed to maintain vehicle
speed.
•
When going down a hill, or long steep grades, prevent over-speeding
of the engine. The engine governor has no control over engine speed
when it is being pushed by a loaded vehicle.
