DIESEL ENGINE BREAK-IN RECOMMENDATIONS

• The Cummins

®

turbocharged diesel engine does not require a break-in period due

to its construction. Normal operation is allowed, providing the following recom-
mendations are followed:

• Warm up the engine before placing it under load.
• Do not operate the engine at idle for prolonged periods.
• Use the appropriate transmission gear to prevent engine lugging.
• Observe vehicle oil pressure and temperature indicators.
• Check the coolant and oil levels frequently.
• Vary throttle position at highway speeds when carrying or towing significant

weight.

NOTE:
Light duty operation such as light trailer towing or no load operation will extend the
time before the engine is at full efficiency. Reduced fuel economy and power may be
seen at this time.
• Because of the construction of the Cummins

®

turbocharged diesel engine, engine

run-in is enhanced by loaded operating conditions which allow the engine parts to
achieve final finish and fit during the first 6,000 miles (10 000 km).

DIESEL ENGINE STARTING PROCEDURES

Engine Block Heater
• For ambient temperatures below 0°F (-18°C), engine block heater usage is

recommended.

• For ambient temperatures below –20°F (-29°C), engine block heater usage is

required.

• The engine block heater cord is routed under the hood to the right side and can be

located just behind the grille near the headlamp.

• Connect the heater cord to a ground-fault interrupter protected 110–115 volt AC

electrical outlet with a grounded, three-wire extension cord.

NOTE:
The block heater will require 110 volts AC and 6.5 amps to activate the heater
element.
• The block heater must be plugged in at least one hour to have an adequate

warming effect on the coolant.

Water In Fuel Message
• If a Water In Fuel message or

indicator appears in the cluster and a chime

sounds five times, the fuel/water separator will need to be drained immediately to
prevent engine damage.

• Refer to “Draining Fuel Water Separator” in this guide for draining instructions or

see your dealer.
