Every 60,000 Miles (100 000 km) Crankcase Depression Regulator Valve (CDRV) System Inspection Engine Accessory Drive Belt Inspection Exhaust Gas Recirculation (EGR) System Inspection (if equipped) Exhaust Pressure Regulator Valve Inspection Maintenance Schedule I - Gasoline Engines With Light Duty Emissions

The services shown in this schedule up to 60,000 miles (1 00 000 km) should be performed after 60,000 miles (100 000 km) at the same intervals.

Footnotes 3 The California Air Resources Board has determined that the failure to perform this maintenance item will not nullify the emission warranty or limit recall liability prior to the completion of vehicle useful life. We, however, urge that all recommended maintenance services be performed at the indicated intervals and the maintenance be recorded. :$* Drive axle service:

Locking Differential - Drain fluid and refill at first engine oil change. At subsequent oil changes, check fluid level and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km).

0 Standard Differential - Check fluid level and add fluid as needed at

every oil change. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km). More frequent lubrication may be required for heavy-duty or off-road use. 3500 HD Models with applications requiring extreme overload/trailer towing conditions and high speed (above 45 mph or 72 kmh) conditions for extended periods of time must have the drive axle fluid changed every 3,000 miles (5 000 km) or 3 months, whichever occurs first, or must use 75W-140 synthetic fluid meeting GM specifications. See “Recommended Fluids and Lubricants” in this section.

Footnotes *<: Drive axle service:

Locking Differential - Drain fluid and refill at first engine oil change. At subsequent oil changes, check fluid level and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km). Standard Differential - Check fluid level and add fluid as needed at every engine oil change. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 00 km). More frequent lubrication may be required for heavy-duty or off-road use. 3500 HD Models with applications requiring extreme overload/trailer towing conditions and high speed (above 45 mph or 72 km/h) conditions for extended periods of time must have the drive axle fluid changed every 3,000 miles (5 000 km) or 3 months, whichever occurs first, or must use 75W-140 synthetic fluid meeting GM specifications.

Footnotes .I, .!. - ~ * - ~ - Drive axle service: 0 Locking Differential - Drain fluid and refill at first engine o i l change.

At subsequent oil changes. check fluid and add fluid as needed. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km).

0 Standard Differential - Check fluid level and add fluid a s needed at every engine oil change. If driving in dusty areas or towing a trailer, drain fluid and refill every 15,000 miles (25 000 km).

0 More frequent lubrication may be required for heavy-duty or off-road

use.

0 3500 HD Models with applications requiring extreme overload/trailer

towing conditions and high speed (above 45 mph or 72 km/h) conditions for extended periods of time must have the drive axle fluid changed every 3.000 miles ( 5 000 km) or 3 months, whichever occurs first, or rnust use 75W-140 synthetic tluid meeting GM specifications.
