Changing the Engine Air Filter - 7.3L
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, and cause the engine to lose power or shut down.
When replacing the air filter element, use a Motorcraft® air filter element. See
Motorcraft Parts
.
Note:
Failure to use the correct air filter element may result in severe engine damage, and may void the vehicle warranty.
Change the air filter element at the correct interval. See
Scheduled Maintenance.
