Cold Weather Starting (Caterpillar®
Diesel)
Because the diesel engine uses compression ignition, it
is harder to start in cold weather than a gasoline engine.
The air intake heater, use of the proper engine oil,
optional engine coolant heater and optional ether
injection system help cold weather starting. See the
Caterpillar
®Diesel Engine Operation & Maintenance
Manual for more information.
Restarting the Diesel Engine While
Moving (Automatic Transmission)
If you have to restart the engine while the vehicle is
moving, shift to N (Neutral).
Stopping the Diesel Engine
1. Apply the parking brake. SeeParking Brake (With
Hydraulic Brakes) on page 2-38orParking Brake
(With Air Brakes) on page 2-41for parking
brake apply procedure.
2. Shift into N (Neutral) for a manual transmission or
P (Park) for an automatic transmission.3. Turn the ignition key to OFF.
If the vehicle has a two-speed axle, seeTwo-Speed
Rear Axle on page 2-36.
If you have a Caterpillar
®diesel engine, see the
Caterpillar®Diesel Engine Operation & Maintenance
Manual for additional information.
Diesel Engine Warm-Up
Several factors affect how quickly the diesel engine
warms up. These can include outside temperature,
engine load, idle time and the vehicle’s option content.
The vehicle may be equipped with some features
that can help the engine reach operating temperature
sooner. Some of these features are discussed below.
Also, remember that an automatic transmission
adds heat to the cooling system through the heat
exchanger in the radiator. Because of this, vehicles
equipped with automatic transmissions are often able to
retain engine coolant heat better than manual
transmission vehicles.
See the Caterpillar
®Operation & Maintenance manual
for additional diesel engine warm-up information.
