Cold Weather Operat ion
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
•
Optional Cold starting aid
•
Battery condition
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 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 Opera tion
•
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 correct specification of engine lubricant
before the beginning of cold weather.
•
Check all rubber parts (hoses, fan drive belts, etc)
weekly.
•
Check all electrical wiring and connections for any
fraying or damaged insulation.
•
Keep all batteries fully charged and warm.
•
Check the air cleaners and the air intake daily.
Personal injury or property damage c an result
from alcohol or starting fluids.
Alcohol or starting fluids are highly flamm able 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 i n an explosion and
personal inj
ury.
Viscosity of t
he Engine Lubricati on
Oil
Correct engine oil viscosity is essential. Oil viscosity
affects the amount of torque that is needed
to crank the e
ngine. Refer to Operation and
Maintenance Manual, “Fluid Recommendations” for
the recommended viscosity of oil.
Recommendations for the Coolant
Provide cooling system protection for the lowest
expected outside temperature. Refer to this Operation
and Mainten
ance Manual, “Fluid Recommendations”
for the recommended coolant mixture.
In cold wea
ther, check the coolant often for the
correct glycol concentration in order to ensure
adequate freeze protection.
Engine Block Heaters
Engine blo
ck heaters (if equipped) heat the
engine jacket water that surrounds the combustion
chambers. This provides the following functions:
•
Startability is improved.
An electri
c block heater can be activated once
the engine is stopped. An effective block heater is
typically a 1250/1500 W unit. Consult your Perkins
distribu
tor for more information.
