Maintenance and Specifications Do not use supplemental transmission fluid additives, treatments or cleaning agents. The use of these materials may affect transmission operation and result in damage to internal transmission components. AIR FILTER Refer to scheduled maintenance information 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 in this chapter. 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. Release the clamps that secure the air filter housing cover. 2. Carefully separate the two halves of the air filter housing. 3. Remove the air filter element from the air filter housing. 4. Wipe the air filter housing and cover clean to remove any dirt or debris and to ensure good sealing. 5. Install a new air filter element. Be careful not to crimp the filter element edges between the air filter housing and cover. This could cause filter damage and allow unfiltered air to enter the engine if not properly seated. 6. Replace the air filter housing cover and secure the clamps. Note: Failure to use the correct air filter element may result in severe engine damage. The customer warranty may be voided for any damage to the engine if the correct air filter element is not used.
