The air cleaner is a paper element type. The paper cartridge should be replaced every 30,000 miles, under normal conditions. Under dusty or severe conditions, the filter should be inspected frequently and changed as necessary.
Check the air filter more often if the vehicle is operated under severe dusty conditions and replace it as necessary.
REMOVAL & INSTALLATION
See Figures 1, 2 and 3
The Ranger, Explorer and Mountaineer vehicles used two types of air cleaner housings: the square panel and the conical (or canister) type. The square panel type retains the housing cover by bolts or, on later models, bail clips. The conical type utilizes a full circumference clamp around the housing.
- Loosen the clamp that secures the intake hose assembly to the air cleaner.
- If necessary, unplug the MAF (Mass Air Flow) and/or IAT (Intake Air Temperature) sensor electrical connector from the air cleaner housing.
Some air cleaner assemblies will have enough "give" in the air inlet pipe and sensor wiring harnesses to allow filter replacement without removing or disconnecting these items.
- Disconnect the hose and inlet tube from the air cleaner.
See Figures 4 and 5
- If equipped with the square panel type housing, remove the screws or bail clips attaching the air cleaner cover.
- If equipped with the conical type housing, unfasten the clamp on the air cleaner body.
- Seperate the lid from the housing base.
- Remove the air filter.
- Installation is the reverse of removal. Don't overtighten the hose clamps! A torque of 12-15 inch lbs. is sufficient.
