I just bought a 2004 Focus.
The cover to air filter is difficult to remove and I dont want to force
it. There is one screw missing, and two screws "spin". The "nut" is
circular so I can't get a wrench on it.
I'm mostlikely going to take vice grips to it and chew everything up,
so I thought I'd ask if there it a trick to taking the cover off and
changing the air filter?
I had the same problem and it was a severe pain (especially in the fingers I
pinched with the pliers) after the dealer said it would
cost $200 to replace the whole box on 2001.
Best thing to do would be soak the bolts and nuts with a penetrate. I would
think a pair of good size needle nose
pliers with a 90 degree bend would be best. There is room to grab the nut,
but not much. I did it without this kind of pliers but next time I am
getting a new pair of pliers.
So the bottom of the circular "nut" is serrated towards the base of the
plastic airfilter cover? Therefore if I oil the screw and apply
pressure between the nut and the bottom airfilter cover it may catch
and allow me to take out the screw?
I had trouble getting mine off first time. I removed the box from the
engine bay and used a combination of penetrating oil and mole grip
pliers to get it undone. Then applied copper grease to all the threads
and not been a problem since.
