STARTING AND OPERATING 297
ENGINE BLOCK HEATER — IF EQUIPPED
The engine block heater warms the engine, and permits
quicker starts in cold weather. Connect the cord to a stan-
dard 110-115 Volt AC electrical outlet with a grounded,
three-wire extension cord.
The engine block heater cord is routed through the grille by
the right front tow hook.
It includes a removable cap that is secured by a tethered
strap. It also has a c-clip that is used for storage when not in
use for the winter months. During winter months, remove
the heater cord wiring assembly from itself on the c-clip.
The engine block heater must be plugged in at least one hour
to have an adequate warming effect on the engine.
ENGINE BREAK-IN RECOMMENDATIONS
A long break-in period is not required for the engine and
drivetrain (transmission and axle) in your vehicle. Drive moderately during the first 300 miles (500 km). After
the initial 60 miles (100 km), speeds up to 50 or 55 mph (80 or
90 km/h) are desirable.
While cruising, brief full-throttle acceleration within the
limits of local traffic laws contributes to a good break-in.
Wide-open throttle acceleration in low gear can be detri
-
mental and should be avoided.
The engine oil installed in the engine at the factory is a
high-quality energy conserving type lubricant. Oil changes
should be consistent with anticipated climate conditions
under which vehicle operations will occur. For the recom -
mended viscosity and quality grades, refer to “Fluids And
Lubricants” in “Technical Specifications”.
NOTE:
A new engine may consume some oil during its first few thou -
sand miles (kilometers) of operation. This should be considered
a normal part of the break-in and not interpreted as a problem.
Please check your oil level with the engine oil indicator often
during the break in period. Add oil as required.
WARNING!
Remember to disconnect the engine block heater cord
before driving. Damage to the 110-115 Volt electrical
cord could cause electrocution.
CAUTION!
Never use Non-Detergent Oil or Straight Mineral Oil in
the engine or damage may result.

SERVICING AND MAINTENANCE 529
Fluid Level Check — Eight-Speed Transmission
The fluid level is preset at the factory and does not require
adjustment under normal operating conditions. Routine
fluid level checks are not required, therefore the transmis-
sion has no dipstick. An authorized dealer can check your
transmission fluid level using special service tools.
If you notice fluid leakage or transmission malfunction, visit
an authorized dealer immediately to have the transmission
fluid level checked. Operating the vehicle with an improper
fluid level can cause severe transmission damage. Fluid And Filter Changes — Eight-Speed Transmission
Under normal operating conditions, the fluid installed at the
factory will provide satisfactory lubrication for the life of the
vehicle.
Routine fluid and filter changes are not required. However,
change the fluid and filter if the fluid becomes contaminated
(with water, etc.), or if the transmission is disassembled for
any reason.
Rear Axle And 4x4 Front Driving Axle Fluid Level
For normal service, periodic fluid level checks are not
required. When the vehicle is serviced for other reasons the
exterior surfaces of the axle assembly should be inspected. If
gear oil leakage is suspected inspect the fluid level. Refer to
“Fluids And Lubricants” in “Technical Specifications” for
further information. This inspection should be made with
the vehicle in a level position.
For all 2500/3500 Model axles, the fluid level should be 1/
4 in ± 1/4 in (6.4 mm ± 6.4 mm) below the fill hole on the
9.25 in front, 11.5 in rear axle, and 12.0 in rear axle.
CAUTION!
If a transmission fluid leak occurs, visit an authorized
dealer immediately. Severe transmission damage may
occur. An authorized dealer has the proper tools to adjust
the fluid level accurately.
