1. Inspect the air filter every 6 months. Replace the air filter every 12 months, or when filter restriction reaches 25 inH20 (if equipped with an air restriction gauge).
2. Replace the organic acid technology (OAT) coolant every 600,000 miles (965 400 km); supplemental coolant additives (SCAs) are not used with OAT coolant. Replace nitrited organic-acid technology (NOAT) and SCA pre-charge ethylene glycol coolants every 30,000 miles (48 270 km). You must check and, if necessary, recharge the SCA levels and freeze point every 25,000 miles (40 225 km) or 6 months, whichever comes first. See the applicable engine operation and maintenance manual for further information. For Cummins engine service literature, refer to the  Cummins Online  website at Cummins Online website. For Cummins engine service literature, refer to the  Cummins Online  website at https://www.cummins.com/support/manuals . For Detroit™ engine service literature, refer to the  Detroit Diesel  link on the DTNA TechLit website https://www.dtnatechlit.com/portal-public .
3. For oil change intervals, see the applicable Eaton Fuller Driver Manual or Service Manual.
4. For oil and filter change intervals, see the applicable Allison Operator's Manual.
5. For Detroit axles, complete this procedure once a year or at the following applicable interval, whichever comes first: every 5000 miles (8000 km) for Schedule I vehicles; or every 10,000 miles (16 000 km) for Schedule II vehicles.
6. For Detroit axles, complete this procedure once a year or at the following applicable interval, whichever comes first: every 5000 miles (8000 km) for Schedule I vehicles; or every 10,000 miles (16 000 km) for Schedule II vehicles.
7. For Detroit rear axles with petroleum-based oil, change the lubricant every 100,000 miles (161 000 km) or every 12 months, whichever comes first; if synthetic oil is used, change the lubricant every 250,000 miles (402 000 km) or every 36 months, whichever comes first. For Meritor rear axles with petroleum-based oil, change the lubricant at 100,000 miles (161 000 km) or at 12 months of service, whichever comes first, and every 24 months thereafter; if synthetic oil is used, change the lubricant every 250,000 miles (402 000 km) or every 36 months, whichever comes first.
8. If equipped with an oil-coalescing desiccant cartridge, replace the cartridge once a year, regardless of mileage.
9. Meritor Q Plus brake system slack adjusters and camshaft brackets use a special NLGI Grade synthetic polyurea grease and do not require lubrication for 3 years or 500,000 miles (800 000 km), whichever comes first.
10. Meritor Q Plus brake system slack adjusters and camshaft brackets use a special NLGI Grade synthetic polyurea grease and do not require lubrication for 3 years or 500,000 miles (800 000 km), whichever comes first.
