Air Cleaner (Gasoline Engines) - GMC SIERRA 1997 Manual

Air Cleaner (Gasoline Engines)
Your air cleaner is located between the battery and
coolant recovery tank.
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 in the air intake
tube between the air cleaner
and the engine.
See "Owner Checks and Services" in the Index to
determine 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.
