Wastegate Actuator: Testing and Inspection

TURBOCHARGER WASTEGATE ACTUATOR CHECK







1. Connect a hand vacuum pump (pressure-application type) to nipple.

CAUTION
In order to abovid damage to the diaphragm, do not apply a pressure of 117 kPa or higher.

2. While gradually applying pressure, check the pressure that begins to activate (approximately 1 mm stroke) the wastegate actuator rod.

Standard value: Approximately 100 kPa

3. If there is a significant deviation from the standard value, check the actuator or the wasteg ate valve: replace if necessary.
