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:
Operating your vehicle in heavy snowfall or extreme rain conditions may allow excessive amounts of snow or water into the air intake system. This could plug or soak the air filter that could cause the engine to lose power or shut down.
When replacing the air filter element, use a Motorcraft® air filter element. See
Motorcraft Parts - 7.3L.
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.
Locate the mass air flow sensor electrical connector on the air outlet tube. Disconnect the mass air flow sensor electrical connector.
Reposition the locking clip on the connector, squeeze the connector and pull it off of the air outlet tube.
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.
Pull the air tube off from the air cleaner housing.
Remove the clips that secure the air filter housing cover.Push the air filter cover toward the center of the vehicle and up slightly to release it.
Remove the air filter element from the air filter housing.
Install the new air filter element.
Engage the clips to secure the air filter housing cover to the air filter housing.Be careful not to crimp the filter element edges between the air filter housing and cover.Ensure that you align the tabs on the edge properly into the slots.
Slip the air tube onto the air filter housing and tighten the air-tube clamp bolt snugly. Do not over tighten air-tube clamp bolt.
Reconnect the mass air flow sensor electrical connector to the outlet tube. Make sure the locking tab on the connector is in the locked position.
