•  To provide high torque and response in all engine-speed ranges, a two-stage turbocharger has been adopted in which one small and one large turbocharger are selectively operated according to driving conditions.

•  To restrict the emission of NOx and carbon, a two-stage turbocharger has been adopted which can assure oxygen even under a low-compression ratio and high EGR (exhaust gas recirculation) condition.

•  Because of the low-compression ratio, ignition worsens during cold periods, however, the small-type turbocharger compresses and heats the intake air for improved ignition stability.

•  As a water pipe No.2 installation note (positioning for installation), pinch the flange nut (M10: Aoorox. 9 mm) and tighten water pipe No.2 (turbocharger side).

•  Measure the distance between water pipes No.2 and No.3 and verify that they are installed correctly.

•  When assembling the turbocharger sub component to the engine, follow the engaging order at the cylinder head engaging part.

•  Store the turbocharger sub component with the turbine inlet flange facing upward.

•  Store the turbocharger with the turbine wheel spindle horizontal.Do not hold the turbocharger actuator rod. In addition, do not touch the turbocharger actuator rod adjustment nut.

•  Connect the vacuum pipe (pipe hose solenoid valve) correctly (marking color should be matched).

•  Connect the solenoid valve harness correctly.

•  Not applicable

•  When installing to the engine, the water pipe could be installed incorrectly. If the water pipe is forcefully assembled, it may be damaged and water leakage may occur.

•  If the turbocharger sub component is not stored in the correct posture, excessive force may be applied to the water pipe, oil pipe, and actuator pipe and they may be deformed or damaged.

•  If the turbocharger is stored with its spindle in the vertical direction, oil inside the center housing may run down the spindle into the turbine compressor housing.

•  The actuator rod may be deformed or damaged, or if the adjustment of the actuator is out of tune, the drive performance may be lowered or the turbocharger may be damaged.

•  If the vacuum pipe is connected incorrectly or it is not connected, the drive performance may be lowered or the turbocharger may be damaged.

•  Be very careful because the same two solenoid valves are positioned closely. If connected incorrectly, the drive performance may be lowered or the turbocharger may be damaged.
