MAINTENANCE Item 16 – Exhaust System Item 18 Radiator 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. 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. 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.
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. 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. 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. 70 All information subject to change without notice. DDC-SVC-MAN-0039 Copyright © 2009 DETROIT DIESEL CORPORATION
