OnDemand step-by-step maintenance & repair BETA

Ford Focus 2005 - 2011  | 1.6 ZETEC Air filter change

  • time 5 to 45 minutes
  • difficulty 1
Caution: Never drive the vehicle with the air cleaner filter element removed. Excessive engine wear could result, and backfiring could even cause a fire under the bonnet
1 The air filter element is located in the air filter housing on the left-hand side of the engine compartment, as viewed from the driver's seat
2a Undo these four air filter cover bolts (arrowed)...
2b ...lift up the cover...
2c ...and remove the filter element
3 If carrying out a routine service, the element must be renewed regardless of its apparent condition
4 If you are checking the element for any other reason, inspect its lower surface; if it is oily or very dirty, renew the element. If it is only moderately dusty, it can be re-used by blowing it clean from the upper to the lower surface with compressed air. Because it is a pleated-paper type filter, it cannot be washed or re-oiled. If it cannot be cleaned satisfactorily with compressed air, discard and renew it
Caution: Wear eye protection when using compressed air
5 Wipe out the inside of the housing. Check that no foreign matter is visible, either in the air inlet or in the air mass meter
6 Refitting is the reverse of the removal procedure, noting the following points:
  1. Make sure that the filter is fitted the correct way up (observe any direction-of-fitting markings).
  2. Ensure that the element and cover are securely seated, so that unfiltered air cannot enter the engine.
  3. Where removed, secure the cover with the bolts, and ensure that the air inlet duct securing clip is fully tightened.
