Cold Weather 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 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 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. This means that 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.
• 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.
• For jump starting with cables in cold weather, refer
to the Operation and Maintenance Manual,
“Starting with Jump Start Cables.” for instructions.
