•Do not increase engine speed
until the oil pressure gauge
indicates normal pressure (as
indicated by the arrows); this
should be indicated on the gauge
within 15 seconds after starting.
•Idle the engine for three to five
minutes before operating with a
full load.
•Try to limit engine idle to
10 minutes. Excessive idling reduces fuel economy.
•When starting a cold engine, increase the engine speed (RPM) slowly
to make sure adequate lubrication is available to the bearings.
Cold weather operation
WARNING:Do not use volatile starting aids such as ether,
propane or gasoline in the engine air intake system. Glow plugs
may ignite vapors which can cause engine damage or personal injury.
In order to operate the engine in temperatures of 32°F (0°C) or lower,
read the following instructions:
•Make sure that the batteries are of sufficient size and are fully
charged. Check other electrical components to make sure they’re in
optimum condition.
•Use a permanent-type engine coolant solution to protect the engine
against damage from freezing.
•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 –4°F (–20°C) or below, it is recommended that you
use a crankcase-mounted coolant heater to improve cold engine
starting.
•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.
