weather.
During
cold

the
starting

the
operation
of
the
diesel
engine
is
dependent
on
the
following
items:
• The type of fuel that is used
• The viscosity of the engine oil
• The operation of the glow plugs
• Optional Cold starting aid
• Battery condition
• Ambient air temperature and altitude
• Parasitic load of the application
• Application hydraulic and transmission oil
viscosities
This section will cover the following information:
• Potential problems that are caused by cold-
weather operation
• Suggest steps which can be taken in order to
minimize starting problems and operating
problems when the ambient air temperature is
between 0° to−40 °C (32° to 40 °F).
The operation and maintenance of an engine in
freezing temperatures is complex . This complexity is
because of the following conditions:
• Weather conditions
• Engine applications
Recommendations from your Perkins dealer or your
Perkins distributor are based on past proven
practices. The information that is contained in this
section provides guidelines for cold-weather
operation.
Hints for Cold Weather Operation
• If the engine will start, operate the engine until a
minimum operating temperature of 81 °C
(177.8 °F) is achieved. Achieving operating
temperature will help prevent the intake valves
and exhaust valves from sticking.
• The cooling system and the lubrication system for
the engine do not lose heat immediately upon
shutdown. This means that an engine can be shut
down for a period of time, and the engine can still
be ability to start readily.
• Install the correct specification of engine lubricant
before the beginning of cold weather.
• Check all rubber parts (hoses, fan drive belts.)
weekly.
• Check all electrical wiring and connections for any
fraying or damaged insulation.
• Keep all batteries fully charged and warm.
• Fill the fuel tank at the end of each shift.
• Check the air cleaners and the air intake daily.
Check the air intake more often when you operate
in snow.
• Ensure that the glow plugs are in working order.
Refer to Testing and Adjusting Manual, “Glow Plug
- Test”.
Personal injury or property damage can result
from alcohol or starting fluids.
Alcohol or starting fluids are highly flammable
and toxic and if improperly stored could result in
injury or property damage.
Do not use aerosol types of starting aids such as
ether. Such use could result in an explosion and
personal injury.
