CHANGING THE ENGINE AIR
FILTER
WARNING
To reduce the risk of vehicle damage
and personal burn injuries, do not
start your engine with the air cleaner
removed and do not remove it while the
engine is running.
Note: Failure to use the correct air filter
element may result in severe engine
damage. Resulting component damage
may not be covered by the vehicle Warranty.
When changing the air filter element, use
only the air filter element listed. See
Motorcraft Parts (page 304).
Change the air filter element at the correct
interval. See Scheduled Maintenance
(page 456).
1. Locate the mass air flow sensor
electrical connector on the air outlet
tube. Disconnect the mass air flow
sensor electrical connector.
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 from around the air tube
to the air cover connection to prevent
debris from entering the system. Next,
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.
