Change extended life coolant
**(See note 1 below)
NOTE
Refer to the following footnotes
when referenced in the preceding
maintenance schedules.
1.
A heavy-duty extended life
coolant (ELC) that meets ASTM
D 6210 chemical composition
specifications must be used. The
change interval is 750,000 mi
(1,200,000 km) or 22,000 hours
on-road use (8 years or 15,000
hours off-highway use) on initial
fill with no extender added. The
change interval is 1,000,000 mi
(1,600,000 km)/20,000 hours/8
years with an extender addition at
500,000 mi (800,000 km)/10,000
hours/4 years. Antifreeze
is essential for freeze and
corrosion protection. The use of
supplemental coolant additives
(SCAs) is not recommended.
2.
The lubricating oil and lubricating
oil filter interval can be adjusted
based on application, fuel
consumption, gross vehicle
weight, and idle time. See the
“Oil Drain Intervals” table in this
procedure.
3.
Service interval is every oil change
or 15,000 mi (24,000 km), 500
hours, or 6 months, whichever
occurs first. A heavy-duty
year-round antifreeze that meets
the chemical composition of
GM6038M must be used. The
change interval is 2 years
or 240,000 mi (385,000 km),
whichever occurs first. Antifreeze
is essential for freeze and
corrosion protection. SCA is
essential for liner pitting and
scaling protection.
4.
If equipped with rubber type
crankshaft vibration damper.
5.
Follow the manufacturers'
recommended maintenance
procedures for the starter,
alternator, batteries, electrical
components, engine brake,
exhaust brake, charge-air cooler,
radiator, air compressor, air
cleaner, refrigerant compressor,
and fan clutch.
6.
Reset valve lash, if needed, to
nominal specifications. Refer to
“General Engine Specifications”
7.
The aftertreatment diesel
particulate filter clean/replace
interval is based on the use of
lubricating oils that meet the
Cummins Engineering Standard
(C.E.S.) 20081 oil specification.
