Cold Weather Operation
Perkins Diesel Engines can operate effectively in
cold weather. During cold weather, the starting and
the operation of the diesel engine depends 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 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
• After starting the engine, the engine speed will be
governed for up to a maximum of 30 seconds.
After this period, the engine should be operated at
low loads until a minimum coolant 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
shutdown for a period and the retained heat within
the engine will allow the engine readily start.
• 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 correct
operation 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.
