MAINTENANCE
Item 15 – Air System
All the connections in the air system
should be checked to make sure
they are tight and leak free. Check
all hoses and ducting for punctures,
deterioration or other damage and
replace, if necessary.
Item 16 – Exhaust System
Have the exhaust manifold retaining
bolts and other connections checked
for tightness. Have the exhaust pipe
rain cap checked for proper operation,
if so equipped.
Item 17 – Engine (Steam Clean)
Steam clean the engine and engine
compartment every 60,000 miles
(96,000 km) or 2,000 hours,
whichever comes first.
NOTICE:
Do not apply steam or solvent
directly to the battery-charging
alternator, starting motor, DDEC
components, sensors or other
electrical components, as damage
to electrical equipment may result.
Item 18 – Radiator
The exterior of the radiator core
should be inspected every 30,000
miles (48,000 km), 12 months, or 300
hours (industrial applications) and
cleaned, if necessary.
EYE INJURY
To avoid injury from flying debris
when using compressed air, wear
adequate eye protection (face
shield or safety goggles) and do
not exceed 40 psi (276 kPa) air
pressure.
Use a quality grease solvent, such
as mineral spirits, and dry with
compressed air. Fuel oil, kerosene or
gasoline should not be used.
It may be necessary to clean the
radiator more frequently if the engine
is being operated in extremely dusty
or dirty areas.
If the low coolant level sensor is
installed in the top tank of the radiator,
it should be tested for proper operation
every 100,000 miles (160,000 km)
or 12 months, whichever comes first.
Authorized Detroit Diesel distributors
are properly equipped to perform this
service.
