When changing the air filter element, use only the air filter element
listed. See Motorcraft® Part Numbers in the Capacities and
Specifications chapter.
See Scheduled Maintenance Information for the appropriate intervals
for changing the air filter element.
Note: Failure to use the correct air filter element may result in severe
engine damage. The customer warranty may be void for any damage to
the engine if the correct air filter element is not used.
Changing the Air Filter Element
1. Disconnect the fresh air inlet
tube from the radiator support.
2. Open the clamp that secures the
two halves of the air filter housing
together.
3. Carefully separate the two
halves of the air filter housing.
4. Remove the air filter element
from the housing.
5. Install a new air filter element. Be careful not to crimp the filter
element edges between the air filter housing. This could cause filter
damage and allow unfiltered air to enter the engine if not properly
seated.
6. Replace the two halves of the air filter housing and secure the clamp.
7. Connect the fresh air inlet tube to the radiator support.
