Wastegate Actuator: Testing and Inspection
Turbocharger Components
Actuator Assembly Mounting
The waste-gate actuator assembly can be replaced separately from the turbocharger assembly. To check operation of the waste-gate actuator:
1. Pull the waste-gate actuator rod toward the rear of the engine (use care not to bend the rod).
2. Release the rod. The rod should snap back to the closed position.
If the rod does not snap back to a closed position, the waste-gate actuator is defective and should be replaced.
