Changing Air Filter in F-53
Just got done changing the air filter in my 2007 373 on a F-53. Had so much fun thought I would write a post that may same someone else a minute or two. Warning this may not be the best way or the right way but its what worked for me. The housing is simple to get to and the three clips on the front flip up easy. Now the fun, in theory you can remove the air tube from the top of the box, push the air box top to the back and lift up to disengage the rear clips and lift the top off of the unit. I found that the air tube is so stiff on mine that pushing it off the attachment tube on the air box top impossible. Instead I removed the engine cover and loosened the clamp holding the air tube onto the intake of the engine and what appears to be a pcv hose from the air tube by pushing the green retainer to the passenger side to clear its clip and then forward. This allowed me to be able to pull the air tube to the rear so the front of it could be removed from the top of the air box. Then the top of the air box can be lifted and the filter element changed. Now the front drivers side clip snaps into the lower air box horizonally where the other two snap in vertically now I do not know if this is a safety warning if the element is not in correctly or some secret Ford planning but I do know if there is any pressure on the filter box top this clamp will keep popping off. So I learned to reattached the Air box top and its three clips first. I then put the air tube back on to the air box and tightened the clamp. Then went inside and attached the other end of the air tube on to the intake and tightened its clamp, reattached the PVC line and closed the engine cover back up. Its not really a bad job, like most stuff in these, its doing it for the first time in a space that is almost to tight. Only tool needed is a straight blade screwdriver to fit the hose clamps.
