•
If your vehicle is equipped with a water-fuel separator, drain it daily.
Fill the fuel tank at the end of daily operation to prevent condensation
in the fuel system.
•
Make sure you use proper cold weather engine oil and that it is at its
proper level.
•
At temperatures of –20°C (–4°F) or below, it is recommended that you
use a crankcase-mounted coolant heater to improve cold engine
starting.
•
If operating in arctic temperatures of –29°C (-20°F) 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 45 Cetane Diesel fuel or use Cetane Index
improvers from a reputable manufacturer.
•
Maintain a minimum idle of 1250 RPM by using the hand throttle.
Always make sure that the parking brake is applied and the
transmission is in neutral before applying the hand throttle.
•
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.
•
Consider using an engine block heater, approved winter fronts and/or
radiator shutters where conditions warrant.
Winter fronts
The use of winter fronts, or other air-restrictive devices mounted in front
of the radiator on vehicles with chassis-mounted charge air coolers, are
not recommended unless extremely cold weather conditions exist. Air
flow restriction can cause high exhaust temperatures, power loss,
excessive fan usage and a reduction in fuel economy. If you insist on
using a winter front, the device should have a permanent opening of at
least 774 sq. cm (120 sq in.) directly in line with the fan hub.
