WARNING: 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 276 kPa (40 psi) air pressure.
NOTE: It may be necessary to clean the exterior of the radiator more
frequently if the engine is being operated in extremely dusty or dirty areas.
2. If necessary, clean the exterior using a quality grease solvent, such as
mineral spirits, and dry with compressed air. Do not use fuel oil, kerosene,
or gasoline.
3. If the low coolant level sensor is installed in the top tank of the radiator, test
for proper operation every 100,000 miles (160,000 km) or 12 months,
whichever comes first. Authorized Detroit™ distributors are properly
equipped to perform this service.
Monitoring the Cooling System Filter
NOTE: DD Platform engines built 2015 and later may not be equipped with
a coolant filter.
Install a new cooling system filter at the distance intervals indicated by each
specific Maintenance Interval chart.
Current engine designs no longer use coolant filters. If you have a coolant filter,
you may choose to remove the filter at your next maintenance interval. For more
details reference bulletin 15TS-10Rev (http://ddcsn-ddc.freightliner.com/cps/rde/
xbcr/ddcsn/15TS10Rev.pdf).
Monitoring the Fuel Filters
Monitoring the Three-Filter Fuel System Filters
The engine is equipped with a prefilter that filters down to 100 microns, a water
separator/coalescer that separates water and also filtering out particles down to 10
microns, and a final filter which filters material from 3 to 5 microns. The final filter
is 98% effective at filtering material at 5 microns. When servicing these elements,
all three filters should be changed at the same time. All three elements are located
within the fuel filter module located on the left side of the engine.
1. Located at the base of the fuel filter module is a water level sensor. Check
the water level sensor each day.
