The air cleaner is a dry-type, chemically treated, pleated paper element. The paper cartridge should be replaced every 30,000 miles (48,000 km).
Check the air filter more often if the vehicle is operated under severe (especially dusty) conditions and replace or clean it as necessary.
The air inducation system functions as follows:
- Outside air flows from an air intake into the air tray through an opening in the front fender.
- The incoming air is filtered by the paper element in the air tray.
- From the air tray, the filtered air flows through the Mass Air Flow (MAF) sensor and air cleaner outlet tube into the trhottle body.
The Positive Crankcase Ventilation (PCV) system uses filtered air from the induction system. The air for the PCV system is taken from the air cleaner outlet tube via a fitting and hose.
On 3.8L and 5.0L engines, air induction noise is controlled by means of a sealed cover with an integral resonator, which is a part of the MAF sensor unit.
REMOVAL & INSTALLATION
See Figures 1 through 8
- Disconnect the negative battery cable.
- Label and disconnect all hoses, tubes and wires connected to the air filter assembly or outlet hose.
- Unfasten the clamps that attach the air tray to the MAF sensor housing.
- Separate the MAF sensor housing from the air tray and position the MAF sensor aside.
Before removal, be sure to note the proper positioning of the element within the housing for installation purposes.
- Remove the filter element from the air tray.
- Using a damp rag, clean all of the inside surfaces of the air tray.
- Install the air filter element (as noted during removal) and position the MAF sensor against the air tray.
- Fasten the retaining clamps, then connect all hoses, tubes and wires to the air induction components.
- Connect the negative battery cable.
