Engine Block Heater:
The block heater cord is located in the rear engine compartment. The block
heater, depending on engine size, is rated between 850-1500 watts. The block
heater cord may be connected to a separate power cord as long as the power cord
is rated for 1500 watts and the outlet used must be GFCI protected rate at 20 Amps.
The engine may require several hours of pre-heating before it will start. It is
recommended to start pre-heating the engine the night before departure.
Remember to unplug the separate power cord.
WARNING: Do not use ether cold starting aids to aid in starting the
engine as engine damage may occur.
Following the maintenance guidelines in the engine manufacturer OEM
Manual recommendations for the engine will help to extend engine life and
improve performance, resulting in cost efficient operations. A good
maintenance schedule begins with a daily awareness of the engine and its
various systems.
A high grade 15W-40 multi-viscosity heavy-duty lubricating oil meeting
Cummins Engineering Specification CES 20071 or CES 20076, American
Petroleum Institute (API) specification CH-4 that can be used as an alternative to
CES 20071 is recommended. Lubricating oils meeting API CG-4 specifications
may be used at a reduced drain interval. The engine uses Pennzoil 15W-40
heavy-duty engine lubricating oil that meets Cummins specifications. A
critical factor in maintaining engine performance and durability is the use of
high-grade multigrade lubricating oil and strict adherence to the maintenance
service intervals.
A straight weight or monograde lubricating oil is not recommended.
Shortened drain intervals may be required as determined by a close monitoring
of the lubricating oil condition by means of an oil-sampling program. The use
of oil analysis to extend drain interval is not recommended. There are numerous
variables, which is the basis of the recommendation.
Synthetic oils API category III specifications are recommended for
extreme cold temperatures only.
Low viscosity oils, used for winter operations, will aid in starting.
Synthetic oils, or oil with adequate low temperature properties used for Arctic
operations where the engine cannot be kept warm when shut down, will aid in
starting.
The use of synthetic oils should not be used to extend drain intervals.
Extended oil change intervals can decrease engine life and possibly affect the
engine warranty.
