MAINTENANCE

The design of the installation must take into account the engine's need for periodic maintenance
and allow access to these service points.
A schedule of periodic maintenance will provide for long term efficiency of the cooling system
and extended engine life. Daily visual inspections should be made of the coolant level and the
overall condition of the system components. This should include looking for obvious leaks and
abnormal distress of the following components:
□ Radiator Core and CAC - Contaminated with oil, dirt and debris; fins/tubes damaged
□ Fill Cap/Neck - Dirty or damaged seats; gasket/seal deteriorated
□ Fan - Blades bent, damaged or missing
□ Belts/Pulleys - Loose belts; frayed; worn; missing
□ Fan Shroud - Loose; broken; missing
□ Hoses/Plumbing - Frayed; damaged; ballooning; collapsing; leaking
□ Coolant - Contaminated, concentration
□ Recirculation Baffles - Missing; not sealing
If any of the above conditions are observed, corrective action should be taken immediately.
Any time a coolant gauge, warning, shutdown, or low level device is malfunctioning, it should
be fixed immediately.
A proper glycol (ethylene, propylene, or extended life organic acid), water, SCA mixture meeting
DDC requirements is required for year-round usage.
the coolant provides freeze and boil protection and reduces corrosion, sludge formation, and
cavitation erosion. antifreeze concentration should not exceed 67% for ethylene glycol (50% for
propylene glycol). Detroit Diesel requires SCAs be added to all cooling systems at initial fill and
be maintained at the proper concentration. Follow SCA manufacturers' recommendations.
