Removal Procedure


    Object Number: 602324  Size: SH
  1. Disconnect the mass air flow/intake air temperature (MAF/IAT) sensor electrical connector.
  2. Loosen the intake air duct clamp at the throttle body.
  3. Lift the air cleaner element assembly off of the air inlet assembly locating pins.
  4. Slide the air cleaner element assembly toward the fender to separate the air cleaner element assembly from the air inlet assembly.
  5. Remove the air cleaner element assembly and intake air ducting from the throttle body.
  6. Loosen the clamp connecting the air cleaner element to the MAF/IAT sensor assembly.
  7. Notice: 

       • Handle the MAF sensor carefully.
       • Do not drop the MAF sensor in order to prevent damage to the MAF sensor.
       • Do not damage the screen located on the air inlet end of the MAF.
       • Do not touch the sensing elements.
       • Do not allow solvents and lubricants to come in contact with the sensing elements.
       • Use a small amount of a soap based solution in order to aid in the installation.

  8. Carefully, separate the air cleaner element assembly from the MAF/IAT sensor assembly.

Installation Procedure


    Object Number: 602324  Size: SH
  1. Install the air cleaner element.
  2. Ensure the rubber locating grommets are secure in the bottom of the air cleaner element assembly.
  3. Slide the locating tab on bottom of the air cleaner element assembly down into the slot in the air inlet assembly.
  4. Press the air cleaner element assembly down onto the locating pins ensuring the locating grommets are secure in the bottom of the air cleaner element assembly.
  5. Notice: 

       • Handle the MAF sensor carefully.
       • Do not drop the MAF sensor in order to prevent damage to the MAF sensor.
       • Do not damage the screen located on the air inlet end of the MAF.
       • Do not touch the sensing elements.
       • Do not allow solvents and lubricants to come in contact with the sensing elements.
       • Use a small amount of a soap based solution in order to aid in the installation.

    Notice: Use the correct fastener in the correct location. Replacement fasteners must be the correct part number for that application. Fasteners requiring replacement or fasteners requiring the use of thread locking compound or sealant are identified in the service procedure. Do not use paints, lubricants, or corrosion inhibitors on fasteners or fastener joint surfaces unless specified. These coatings affect fastener torque and joint clamping force and may damage the fastener. Use the correct tightening sequence and specifications when installing fasteners in order to avoid damage to parts and systems.

  6. Install the MAF/IAT sensor and intake air ducting along with the clamps between the air cleaner element assembly and the throttle body.
  7. Tighten
    Tighten the clamps to 3 N·m (27 lb in).
