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 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
downforaperiodoftimeandtheenginecanstill
have the ability to start readily.
•
Install the cor
rect specification of engine lubricant
before the beginning of cold weather.
•
Check all rubb
er parts (hoses, fan drive belts, etc)
weekly.
•
Check all elec
trical wiring and connections for any
fraying or damaged insulation.
•
Keep all batte
ries 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 Test
ing and Adjusting Manual, “Glow Plug
-Test”.
Personal injury or property damage can result
from a lcohol or starting fluids.
Alcohol or starting fluids a re highly flammable and
toxic and if improper ly stored could result in injury
or property
damage.
Do not use aerosol types of starting aids s uch as
ether. Such use could result in an explosion and
personal injury.

“Starting with Jump Start Cables.” for instructions.
Viscosity of the E ngine Lubricati on
Oil
Correct engine oil viscosity is essential. Oil viscosity
affects the amount of torque that is needed to
crank the engine. Refer to this Operation and
Maintenance Manual, “Fluid Recommendations” for
the recommended viscosity of oil.
Recommendations for the Coo lant
Provide cooling system protection for the lowest
expected outside temperature. Refer to this Operation
and Maintenance Manual, “Fluid Recommendations”
for the recommended coolant mixture.
