Cold Weather Operation
AMADAS/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 the
necessary. The information below outlines
steps that can minimize the effect that cold
weather may have on the starting and
operation of your engine. See your AMADAS/
John Deere deal
er for additional information
and local availability of cold weather aids.
Winter Blend Diesel Fuel
When temperatures fall below -10°C (14°F),
winter blend diesel fuel is best suited for cold
weather operation. Winter blend diesel fuel
has a lower cloud point and a lower pour point.
Cloud Point is the temperature at which wax
will begin to form in the fuel. This wax causes
the fuel filter to plug.
Pour point is the lowest temperature at which
movement of the fuel is observed.
Air Intake Heater
An intake heater is an available option to aid
cold weather starting.
Ether
An ether port on the intake is available to aid
cold weather starting.
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, page
306, and Diesel Engine Coolant, page 302).
Diesel Fuel Flow Additive
Use John Deere Premium Diesel Fuel
Conditioner (winter formula), which contains
anti-gel chemistry, or equivalent to treat Grade
No.2-
D fuel during the cold weather season.
This generally extends operability about 10°C
(18°F) below its Cloud Point. For operability at
temperatures further below, winter grade fuel
(a blend of No.2-D and No.1-
No.1-
D fuel) is best suited for cold weather
operation.
When running an engine with biodiesel blends,
wax formation can generate at warmer
temperatures. Begin to use John Deere
Premium Biodiesel Conditioner (winter) at 5°C
(40°
F) to treat biodiesel fuels during the cold
weather season. Below 0°C (32°
F) John
Deere requires the use of B5 or lower blends.
Below -10
°C (14°F), John Deere requires the
use of winter blend diesel fuel.
Do NOT use ether when starting an engine
equipped with glow plugs or one using an
Do NOT use ether when starting with an
air intake heater.
IMPORTANT! Treat fuel when outside
temperature drops below 0°C (32°F). For
best results, use with untreated fuel.
Follow all recommended instructions on
NOTE! Winter blend diesel fuel usually
has a lower BTU (heat content) rating.
Using winter blend diesel 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.
