Wastegate Functional Check
- Remove heat shields from turbocharger area. Disconnect linkage from wastegate. Manually operate lever to verify free movement and full travel. If restriction is felt, replace turbocharger.
- If no resistance is felt, connect wastegate linkage. Remove actuator hose from solenoid. Apply 8.5 psi (.59 kg/cm2 ) air pressure to actuator hose and check wastegate operation. If wastegate does not open, replace actuator, linkage and mounting plate.
