Engine Maintenance

Servicing the Air Cleaner

Check the air cleaner body for damage which could
cause an air leak. Replace if damaged. Check the
whole intake system for leaks, damage or loose hose
clamps.
Service the air cleaner filter only when the service
indicator (Figure 69) requires it. Changing the air filter
before it is necessary only increases the chance of
dirt entering the engine when the filter is removed.
Important:
Be sure the cover is seated correctly
and seals with the air cleaner body.
1. Release the latches securing the air cleaner
cover to the air cleaner body

2. Remove the cover from the air cleaner body.
Before removing the filter, use low pressure air
(40 psi, clean and dry) to help remove large
accumulations of debris packed between outside
of the filter and the canister. Avoid using high
pressure air which could force dirt through
the filter into the intake tract.
This cleaning process prevents debris from
migrating into the intake when the filter is
removed.
3. Remove and replace the filter
Cleaning of the used element is not
recommended due to the possibility of damage
to the filter media. Inspect the new filter for
shipping damage, checking the sealing end of
the filter and the body. Do not use a damaged
element. Insert the new filter by applying
pressure to the outer rim of the element to seat
it in the canister. Do not apply pressure to the
flexible center of the filter.

4. Clean the dirt ejection port located in the
removable cover. Remove the rubber outlet
valve from the cover, clean the cavity and
replace the outlet valve.
5. Install the cover orienting the rubber outlet valve
in a downward position—between approximately
5:00 to 7:00 when viewed from the end.
6. Secure the latches.

Servicing the Engine Oil

Oil Specification
Use high-quality, low-ash engine oil that meets or
exceeds the following specifications:
•
API service category CJ-4 or higher
•
ACEA service category E6
•
JASO service category DH-2
Important:
Using engine oil other than API CJ-4
or higher, ACEA E6, or JASO DH-2 may cause the
diesel particulate filter to plug or cause engine
damage.
Use the following engine oil viscosity grade:
•
Preferred oil: SAE 15W-40 (above 0°F)
•
Alternate oil: SAE 10W-30 or 5W-30 (all
temperatures)
