Air Cleaner
To Remove the Air CIeaner Filter:
If you have the 4.3L engine (VIN Code Z) with the round air cleaner, you
must first remove the engine cover before changing the filter. (See "Engine
Cover" earlier in this section.) After removing the engine cover, unscrew the
wing nut to take the cover off the air cleaner. After changing the filter, put
the cover back on and be sure the wing nut is properly tightened. Be sure
air cleaner lid is correctly positioned to seal out dust and contaminants that
are harmful to your engine.
If you have the 4.3L engine (VIN Code W) with the square air cleaner, you
can change the air cleaner filter without removing the engine cover. Just lift
the hood, unsnap both clips and remove the top. After changing the filter,
snap both clips to secure the air cleaner. Be sure air cleaner
lid is correctly
positioned to seal out dust and contaminants that are harmful to your engine.
Refer to the Maintenance Schedule to determine when to replace the air
cleaner filter. See "Scheduled Maintenance Services" in the Index.
