Air Induction Systems (Turbocharger): WASTEGATE

1. Engine must be cool. Remove exhaust manifold insulator and side insulator. Remove hose connected to actuator and connect compressed air source with pressure gauge. See Fig 1 .
2. Apply 10 psi (0.7 kg/cm² ) of compressed air to actuator. Verify actuator rod moves when connecting and disconnecting hose supplying compressed air.

CAUTION: DO NOT apply compressed air more than 14 psi (1.0 kg/cm² ).
