The following procedure is for vehicles equipped with a gasoline engine.
If your vehicle is equipped with a diesel engine, refer to the diesel
supplement.
Note: Do not start your engine with the air cleaner removed and do not
remove it while the engine is running.
Changing the air filter element
1. Locate the mass air flow sensor
electrical connector on the air outlet
tube. This connector will need to be
unplugged.
2. Reposition the locking clip on the
connector (connector shown from
below for clarity), squeeze the
connector and pull it off of the air
outlet tube.
3. Clean the area around the air
tube to air cover connection to
prevent debris from entering the
system and then loosen the bolt on
the air tube clamp so the clamp is
no longer snug to the air tube. It is
not necessary to completely remove
the clamp.
4. Pull the air tube off from the air
cleaner housing. Maintenance and Specifications
