Cold

Operation
Perkins
Diesel
Engines
can
operate
effectively
in
cold
weather.
During
cold
weather,
the
starting
and
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
This section will cover the following information:
• Potential problems that are caused by cold-
weather operation
• Suggest steps which can be taken 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 80° C (176° 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. An engine can be shut down for a
period and the engine can still have the ability to
start readily.
• Install the correct specification of engine lubricant
before the beginning of cold weather. Refer to this
Operation and Maintenance Manual, “Fluid
Recommendations” for the recommended
viscosity of oil.
• 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 by
ensuring that the engine is allowed to operated at
normal operating temperature.
• Fill the fuel tank at the end of each shift.
• Drain the water from the fuel system. Refer to this
Operation and Maintenance Manual, “Fuel System
Primary Filter/Water Separator - Drain”
• 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 Troubleshooting, “Glow Plug Starting Aid-
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.
