Removal Procedure
1. Remove the Intake Air Temperature (IAT) sensor connector.
2. Loosen the clean air duct clamp at the Mass Air Flow Sensor end of the duct.
3. Disconnect the clean air duct from the Mass Air Flow Sensor.
4. Disengage both air cleaner cover latches. One latch is located at the rear corner of the inboard edge of the cover. The other is located at the
outboard corner of the rear edge of the cover.
5. Pivot the air cleaner and clean air duct assembly toward the front of the vehicle.
6. Remove the assembly.
7. Inspect air filter element.
8. Remove any loose debris that may be found laying in the base of the air cleaner.
Installation Procedure
1. Install a new AC 1096C Air filter element.
2. Engage the front edge of the air cleaner lid into the slots in the front edge of the air cleaner base.
Important: The outlet of the air cleaner assembly and the Mass Air Flow Sensor sensor inlet duct must be lined up when completely installed.
Misalignment may cause incorrect air flow readings resulting in Malfunction Indicator Lamp (MIL) illumination or a driveability concern.
3. Pivot air cleaner cover and duct assembly down until the two latches in the cover engage in the air cleaner base.
4. Inspect to be sure that both latches latch.
5. Install the intake air duct over the Mass Air Flow Sensor, being careful to ensure that the intake air duct is secure around the entire outer edge of
the Mass Air Flow Sensor.
