When To Service The Dry Type Air Cleaner - Detroit Diesel 60 Series Operator's Manual

8. With the engine cool, drain the
cleaner residue from the cooling
system.
9. Refill the system with the required
coolant. Refer to Section G.
10. Entrapped air must be purged after
filling the cooling system. To do this,
allow the engine to warm-up without
the pressure cap installed. With the
transmission in neutral, increase
engine speed above 1000 RPM and
add coolant as required.
Install the pressure cap after the
coolant level has stabilized at the bot-
tom of the radiator filler neck.
NOTICE:
If the engine overheats and the
coolant level is satisfactory, the cool-
ing system may require cleaning with
a descaling solvent and backflushing.
Authorized Detroit Diesel service out-
lets are properly equipped to perform
these services.
In addition to the cleaning procedure,
other components of the cooling system
should be checked periodically to keep
the engine operating at peak efficiency.
Hoses. Cooling system hoses should be
inspected and any hose that shows obvi-
ous signs of damage or feels abnormally
soft or hard should be replaced. Damaged
clamps should be replaced. All external
leaks should be corrected as soon as
detected.
NOTE:
If Detroit Diesel Power Cool antifreeze/
coolant (or equivalent fully formulated,
precharged antifreeze) is used, a
precharge element is not required.
Coolant inhibitor levels must be checked
at the intervals listed in Table 16.
I. When to Service the Dry
Type Air Cleaner
Replace dry type air cleaner elements
when the maximum allowable air clean-
er restriction (20 inches of water or 5.0
kPa) has been reached, or annually,
whichever comes first. Some air clean-
ers are equipped with a restriction indi-
cator which aids in determining the
servicing interval.
Cleaning and/or reusing dry paper
type air cleaner elements is not recom-
mended unless the cleaning method
used removes clogging without damag-
ing the element. Inspection and cleaning
of elements must be done in accor-
dance with the air cleaner manufactur-
er's recommendations, if any.
