Maintenance and Specifications The following procedure is for vehicles equipped with a gasoline engine. If your vehicle is equipped with a diesel engine, refer to the diesel supplement. 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. Locate the mass air flow sensor electrical connector on the air outlet tube. This connector will need to be unplugged. 2. Reposition the locking clip on the connector (connector shown from below for clarity), squeeze the connector and pull it off of the air outlet tube. 3. Clean the area around the air tube to air cover connection to prevent debris from entering the system and then 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. 4. Pull the air tube off from the air cleaner housing. 401 2011 F-250/350/450/550 (f23) Owners Guide, 4th Printing USA (fus)
