Cold Weather Starting
Steps for starting the engine in cold
temperatures.
Follow this engine starting procedure when
the outside temperature is below 50° F
(10° C).
CAUTION
To reduce the possibility of damage to
the lubricating oil
pan, due to the ma-
terials used in the manufacture of the
lubricating oil pan, under no circum-
stances should an external heat
source be applied directly or indirectly
to the lubricating oil pan.
1. Follow the Normal Starting
Procedure on page 20.
Refer to the vehicle operator's manual
instructions for any additional cold weather
starting procedures.
2. If starting a cold engine, slowly
increase the engine speed. This
provides adequate lubrication to
the bearings and gives ample time
to allow the oil pressure to
stabilize.
CAUTION
The use of starting aids, such as ether,
may result in
damage to the engine
and aftertreatment system.
If an engine must idle for an extended
period of time, it should be done at a fast
idle (1,000 RPM maximum) at coolant
temperatures below 150°F (70°C).
3. For coolant temperatures below
150°F (70°C), use a low gear and
drive at moderate engine speed
until the engine coolant has
reached operating temperature. Do
not let the engine idle longer than
necessary.
CAUTION
Do not operate the engine at low idle
for long periods
of time when the cool-
ant temperature is below the normal
operating range. This could result in
the following:
• Fuel dilution of the lubricating
oil.
• Carbon buildup in the com-
bustion chamber.
•
Sticking of the valves in the
cylinder head.
• Reduced performance.
• Damage to aftertreatment
components.
Starting Procedure After Extended
Shutdown or Oil Change
Guideline on starting the engine after
prolonged shutdown or oil change.
After extended shutdown or an oil change
follow the Normal Starting Procedure on
page 20.
Operating the Engine
After the engine starts:
Monitor the oil pressure and coolant
temperature gauges frequently. Refer to
Engine Oil Specifications on page
40 and
Engine Coolant Specifications on page 45
for recommended operating pressures and
temperatures. Shut off the engine if any
pressure or temperature does NOT meet
the specifications.
