Replace the air filter Ford F150
Release the filter cover clamps…
… slide the cover forward until the tabs at the rear of the housing are free…
… then lift-off the cover and remove the air filter element
1. The air filter is located inside a housing at the left (driver’s) side of the engine compartment. To remove the air filter, release the housing cover clamps, then lift-off the cover and remove the air filter element.
2. Inspect the outer surface of the filter element. If it is dirty, replace it. If it is only moderately dusty, it can be reused by blowing it clean with compressed air, in the reverse direction of normal engine airflow. Because the factory installed filter is a pleated paper type filter, it cannot be washed or oiled. If it cannot be cleaned satisfactorily with compressed air, discard and replace it.
Caution: Never drive the vehicle with the air filter removed. Excessive engine wear could result and backfiring could even cause a fire under the hood.
3. Wipe out the inside of the air filter housing.
4. Place the new air filter element into the housing, making sure it seats properly.
5. The remainder of installation is the reverse of removal.
