Chevrolet GMC 2002 Owner's Manual Supplement page 52

See "Engine Compartment Overview" in the Index
for more information on location.
See "Owner Checks and Services" in the Owner's
Manual for when to check the indicator.
If the area inside the clear section of the indicator is
green, no air filter service is required. When the area
inside the indicator is orange and CHANGE AIR
FILTER appears, the filter should be replaced.
The air cleaner assembly
has an indicator that lets
you know when the
air filter is dirty and
needs to be serviced.
The indicator is located
between the air cleaner
and the turbocharger.
1. To remove the engine air cleaner/filter, unhook
the retaining clips and remove the cover. Lift the
filter and the connected duct out of the air cleaner
housing. Hold the duct and remove the filter by
both pulling and twisting the filter away from the
duct. Care should be taken to dislodge as little dirt
as possible.
