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.
