Use the 215-2592 Wastegate tool kit .Procedure for Troubleshooting the Wastegate Canister
Note: The following procedure is a check of the actuator rod and the wastegate in order to ensure that the actuator rod and the wastegate are not stuck. This procedure is not meant to be a pressure check.Note: This procedure can be completed while the turbocharger is installed on the engine or while the turbocharger is not installed on the engine.
Remove the silicone hose that is connected to the wastegate canister and install the test kit. Refer to Illustration 1.
Illustration 1 g01717703
(1) Wastegate actuator (2) Test hose
Use the regulator to increase and decrease the air pressure. Do not exceed 138 kPa (20 psi). As the air pressure to the canister increases, the actuator rod will move. The movement of the rod causes the opening of the wastegate and the closing of the wastegate. While the actuator rod is moving, inspect the rod for damage or for bending.
If the actuator rod does not move, then the wastegate canister is faulty and the turbocharger needs to be replaced.
If the actuator rod moves, then the canister is operational.
Disconnect the test kit and install the silicone hose to the wastegate canister.
