AIR FILTER MAINTENANCE
Refer to the scheduled maintenance guide for the appropriate intervals
for changing the air filter element.
When changing the air filter element, use only the Motorcraft air filter
element listed. Refer to Motorcraft Part Numbers.
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. Loosen the clamp that secures
the air filter element in place.
2. Carefully separate the two halves
of the air filter housing.
3. Remove the air filter element
from the open end of the air filter
housing.
4. Install a new air filter element.
5. Reassemble the two halves of the air filter housing, aligning the notch
and slot found on the top of each half. Secure the clamp, making sure
not to crimp the air filter edges between the two halves of the air filter
housing. This could cause filter damage and allow unmetered air to enter
the engine if not properly seated.
