6F-4 ENGINE EXHAUST


Service Precaution
CAUTION:
Always use the correct fastener in the proper location.
When you replace a fastener, use ONLY the exact part
number for that application. ISUZU will call out those
fasteners that require a replacement after removal. ISUZU
will also call out the fasteners that require thread lockers
or thread sealant. UNLESS OTHERWISE SPECIFIED, do
not use supplemental coatings (Paints, greases, or other
corrosion inhibitors) on threaded fasteners or fastener
joint interfaces. Generally, such coatings adversely affect
the fastener torque and the joint clamping force, and may
damage the fastener. When you install fasteners, use the
correct tightening sequence and specifications. Following
these instructions can help you avoid damage to parts
and systems.

Air Cleaner Filter
NOTE:
The air cleaner filter is not damaged with the edge of the air
cleaner housing.

Removal
1. Remove positive ventilation hose connector.
2. Remove intake air temperature sensor.
3. Remove mass air flow sensor.
4. Remove air cleaner duct assembly.
5. Remove air cleaner element.

Inspection
Check the air cleaner filter for damage or dust clogging.
Replace if it is damaged, or clean if it is clogged.



Cleaning Method
Tap the air cleaner filter gently so as not to damage the paper
filter, or clean the element by blowing with compressed air of
about 490 kPa (71 psi) from the clean side if it is extremely
dirty.
