Routine Preventive Maintenance

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

Install a new cooling system filter at the distance intervals indicated by each

specific Maintenance Interval chart.

• Refer to section "Preventive Maintenance Tables".

Monitoring the Fuel System Filters

The engine is equipped with a prefilter that filters down to 100 microns, a

coalescer/final filter that separates water, and filters down to 3 to 5 microns. When

servicing these elements, all two filters should be changed at the same time. All

two elements are located within the fuel filter module located on the left side of the

engine.

NOTICE: Do not over-tighten the water drain valve. Failure to properly

tighten the water drain valve may cause damage to the water drain valve

and housing.

NOTE: Filter change intervals may be shortened to conform with

established preventive maintenance schedules, but should never be

extended.

1. Replace the fuel filters using the Preventative Maintenance Tables.
