Cold Weather Starting
SMCS Code: 1000; 1250; 1450; 1453; 1456; 1900
Note: Oil pan immersion heaters are not
recommended for heating the lube oil. To ensure the
compatibility of the components, only use equipment
that is recommended by Caterpillar.
Startability will be improved at temperatures below
16 °C (60 °F) with a starting aid. A jacket water
heater may be needed and/or the crankcase oil may
need to be warmed.
A jacket water heater is available as an option for
starting in temperatures as low as 0 °C (32 °F). The
jacket water heater can maintain the water
temperature at approximately 32 °C (90 °F). The
heated water will help to keep the oil in the engine
block warm enough to flow when the engine is
started.
Maintain the proper level of electrolyte in the
batteries. Keep the batteries fully charged.
To maximize the battery power, heat the battery
compartment or store the batteries in a warm
location. Typically, batteries only have 50 percent of
the capability at −10 °C (14 °F) versus 27 °C (80 °F)
.
Extra battery capacity may be necessary for very
cold temperatures.
When No. 2 diesel fuel is used, a fuel heater will
maintain the temperature of the fuel above the cloud
point. Fuel line insulation will help to maintain the fuel
temperature.
Consult your Caterpillar dealer for more information
on the starting aids that are available for cold weather
starting.
Starting With the Starting Aid
Switch
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.
NOTICE
Excessive starting fluid can cause piston and ring
damage.
Use starting fluid for cold starting purposes only.
Do not use excessive starting fluid during starting or
after the engine is running.
The optional ether starting aid which is located
on the control panel is the only system that is
recommended for the injection of starting fluid.
Perform the procedures that are described in this
Operation and Maintenance Manual (Operation
Section), “Before Starting Engine”.
1. Turn the Engine Control Switch to the “MAN.
START” position. The engine will crank.
2. Ether will automatically be injected if the following
conditions are met:
a. The “STARTING AID” switch is in the
AUTOMATIC position.
b. The jacket water temperature is less than
21 °C (70 °F).
Note: Additional injections may be necessary in
order to start the engine. Additional injections may
also be necessary in order to achieve low idle.
3. If additional injection is necessary, toggle the
“STARTING AID” switch to the MANUAL position.
For additional injection, the jacket water
temperature must be less than 21 °C (70 °F).
4. The “STARTING AID” switch is a momentary
switch. To stop the injection, release the
“STARTING AID” switch.

Starting with Jump Start
Cables
SMCS Code: 1000; 1401; 1402; 1900
Improper jump start cable connections can cause
an explosion resulting in personal injury.
Prevent sparks near the batteries. Sparks could
cause vapors to explode. Do not allow jump start
cable ends to contact each other or the engine.
If the installation is not equipped with a backup
battery system, it may be necessary to start the
engine from an external electrical source.
