Removal Procedure
- Open the hood.
- If equipped with a mass air flow (MAF) sensor, disconnect the MAF sensor electrical connector.
- Loosen the clamp at the MAF sensor and disconnect the air inlet tube from the MAF sensor.
- If required, remove the engine harness retainers at the air cleaner bracket.
- If required, remove the heater hose retainers.
- If required, remove the air restriction gage tube.
- Remove the oil fill tube bolt from the air cleaner bracket.
- Remove the 4 nuts and 2 bolts from the air cleaner bracket.
- Remove the air cleaner from the cowl.
Note: Take care when handling the mass air flow (MAF). Do Not dent, puncture, or otherwise damage the honey well located at the air inlet end of the MAF. Do Not touch the sensing elements or allow anything, including solvents and lubricants, to come in contact with them. A small amount of GM Lubricant P/N 99855406 may be used on the air duct only to aid in installation. Do Not drop or roughly handle the MAF.
Note: Do not remove any constant tension clamp retaining a bellow to an air cleaner elbow. Once a constant tension clamp is removed the integrity of the clamp is damaged. The sealing joint between a bellow and the air cleaner bellow should not be broken. Once this joint is broken, the air cleaner duct assembly must be replaced.
Installation Procedure
- Install the air cleaner to the cowl with the 4 nuts and 2 bolts.
- Install the oil fill tube to the air cleaner bracket
- If required, install the heater hose retainers.
- If required, install the engine harness retainers.
- If required, connect the MAF sensor electrical connector.
- if required, connect the air restriction gage tube.
- Connect the air inlet tube.
- Tighten the air inlet tube clamp.
Caution: Refer to Fastener Caution in the Preface section.
