Air Bypass Valve Actuator: Service and Repair

SUPERCHARGER BYPASS VACUUM SOLENOID - ACTUATOR

REMOVAL







1. Disconnect the electrical connectors from the EGR vacuum regulator solenoid, the supercharger bypass vacuum solenoid, and the differential pressure feedback EGR system.







2. Disconnect the vacuum hoses from the differential pressure feedback EGR system.







3. Disconnect the vacuum hoses from the supercharger bypass vacuum solenoid, and the actuator.







4. Disconnect the vacuum hoses from the EGR vacuum regulator solenoid.







5. Remove the vacuum accessory bracket mounting nut.







6. Remove the mounting bolts and the vacuum accessory bracket.







7. Remove the actuator mounting bolts.







8. Align the actuator rod with the slot in the actuator linkage, and remove the actuator.

INSTALLATION







1. CAUTION: The actuator adjustment tool included with the replacement actuator kit must be used when installing the supercharger bypass vacuum actuator. Failure to correctly adjust the actuator will result in incorrect operation of the supercharger assembly.

Install the actuator adjustment tool onto the actuator, making sure the tool is correctly attached to the actuator rod. Rotate the actuator into position until the rod engages the lever.







2. Install the actuator.
- Align the actuator rod with the slot in the linkage.







3. Install the actuator bolts.
4. Remove the actuator adjustment tool.







5. Install the vacuum accessory bracket, and the mounting bolts.







6. Install the vacuum accessory bracket mounting nut.







7. Connect the vacuum hoses to the EGR vacuum regulator solenoid.







8. Connect the vacuum hoses to the supercharger bypass vacuum solenoid, and the actuator.







9. Connect the vacuum hoses to the differential pressure feedback EGR system.







10. Connect the electrical connectors to the EGR vacuum regulator solenoid, the supercharger bypass vacuum solenoid, and the differential pressure feedback EGR system.
