For your convenience, listed below are the section numbers that contain specific instructions for performing the maintenance checks listed in the maintenance schedule. Perform maintenance at whichever interval occurs first. At each scheduled maintenance interval, perform all previous checks that are due for scheduled maintenance. Maintenance Procedures at Daily Interval4 (Section 3) Drive Belts - Check Coolant Level - Check Cooling Fan - Check Lubricating Oil Level - Check Fuel-Water Separator - Drain Maintenance Procedures at 10,000 Kilometers [6000 miles], 250 Hours, or 3 Months1, 4 (Section 4) Air Cleaner Restriction - Check Charge Air Cooler - Check Charge Air Piping - Check Lubricating Oil and Filters - Change Air Intake Piping - Check Air Compressor - Check Radiator Pressure Cap - Check Maintenance Procedures at 19,000 Kilometers [12,000 miles], 500 Hours, or 6 Months2, 3, 4 (Section 5) Coolant Filter - Change Supplemental Coolant Additive (SCA) and Antifreeze - Check Cooling System - Check Fuel Filter (Spin-On Type) - Change Maintenance Procedures at 38,000 Kilometers [24,000 miles], 1000 Hours, or 1 Year4 (Section 6) Cooling Fan Belt Tensioner - Check Overhead Set - Adjust Drive Belts - Check Maintenance Procedures at 77,000 Kilometers [48,000 miles], 2000 Hours, or 2 Years2, 3, 4, 5 (Section 7) Air Compressor Discharge Lines - Check Cooling System - Flush Vibration Damper, Rubber - Inspect for Reuse Vibration Damper, Viscous - Inspect for Reuse The lubricating oil and lubricating oil filter interval can be adjusted based on fuel consumption, gross vehicle weight, and idle time. Refer to Oil Drain Intervals in this section. Test the SCA concentration level every 6 months unless concentration is over three units; then check at every oil drain interval until concentration is below three units. Antifreeze check interval is every oil change or 19,000 Kilometers [12,000 Miles], 500 hours or 6 months, whichever occurs first. The operatormust use a heavy-duty year-round antifreeze that meets the chemical composition of ASTM D6210. The antifreeze change interval is 2 years or 77,000 Kilometers [48,000 Miles], whichever occurs first. Antifreeze is essential for freeze, overheat, and corrosion protection. Follow the manufacturer's recommended maintenance procedures for the starter, alternator, generator, batteries, electrical components, engine brakes, exhaust brake, charge-air cooler, air compressor, refrigerant compressor, and fan clutch. This cooling system requirement to Flush at this scheduled maintenance includes Drain, Flush, and Fill.
