Minimizing the Effect of Cold Weather on Diesel Engines
John Deere diesel engines are designed to operate
effectively in cold weather.
However, for effective starting and cold-weather
operation, a little extra care is necessary. The following
information outlines steps that can minimize the effect
that cold weather may have on starting and operation of
your engine. See your John Deere dealer for additional
information and local availability of cold-weather aids.
Use Winter Grade Fuel
When temperatures fall below 0 °C (32 °F), winter
grade fuel (No. 1-D in North America) is best suited for
cold-weather operation. Winter grade fuel has a lower
cloud point and a lower pour point.
Cloud point is the temperature at which wax begins to
form in the fuel. This wax causes fuel filters to plug. Pour
point is the lowest temperature at which movement of
the fuel is observed.
NOTE: On average, winter grade diesel fuel has a lower
Btu (heat content) rating. Using winter grade fuel
may reduce power and fuel efficiency, but should not
cause any other engine performance effects. Check
the grade of fuel being used before troubleshooting
for low-power complaints in cold-weather operation.
Air Intake Heater
An air intake heater is an available option for some
engines to aid cold weather starting.
Ether
An ether port on the intake is available to aid cold weather
starting.
CAUTION: Ether is highly flammable. Do not
use ether when starting an engine equipped
with glow plugs or an air intake heater.
Coolant Heater
An engine block heater (coolant heater) is an available
option to aid cold weather starting.
Seasonal Viscosity Oil and Proper Coolant
Concentration
Use seasonal grade viscosity engine oil based on the
expected air temperature range between oil changes
and a proper concentration of low silicate antifreeze as
recommended. (See DIESEL ENGINE OIL and ENGINE
COOLANT requirements in this section.)
Diesel Fuel Flow Additive
Use John Deere Fuel-Protect Diesel Fuel Conditioner
(winter formula), which contains anti-gel chemistry, or
equivalent fuel conditioner to treat non-winter grade fuel
(No. 2-D in North America) during the cold-weather
season. This generally extends operability to about 10 °C
(18 °F) below the fuel cloud point. For operability at even
lower temperatures, use winter grade fuel.
IMPORTANT: Treat fuel when outside temperature
drops below 0 °C (32 °F). For best results, use
with untreated fuel. Follow all recommended
instructions on label.
BioDiesel
When operating with BioDiesel blends, wax formation can
occur at warmer temperatures. Begin using John Deere
Fuel-Protect Diesel Fuel Conditioner (winter formula) at 5
°C (41 °F) to treat BioDiesel fuels during the cold-weather
season. Use B5 or lower blends at temperatures below
0 °C (32 °F). Use only winter grade petroleum diesel fuel
at temperatures below -10 °C (14 °F).
Winterfronts
Use of fabric, cardboard, or solid winterfronts is not
recommended with any John Deere engine. Their use
can result in excessive engine coolant, oil, and charge
air temperatures. This can lead to reduced engine life,
loss of power and poor fuel economy. Winterfronts may
also put abnormal stress on fan and fan drive components
potentially causing premature failures.
If winterfronts are used, they should never totally close
off the grill frontal area. Approximately 25% area in the
center of the grill should remain open at all times. At no
time should the air blockage device be applied directly
to the radiator core.
Radiator Shutters
If equipped with a thermostatically controlled radiator
shutter system, this system should be regulated in such
a way that the shutters are completely open by the time
the coolant reaches 93 °C (200 °F) to prevent excessive
intake manifold temperatures. Manually controlled
systems are not recommended.
If air-to-air aftercooling is used, the shutters must be
completely open by the time the intake manifold air
temperature reaches the maximum allowable temperature
out of the charge air cooler.
