3. TROUBLESHOOTING

The followings are cautions to take in handling defects of turbocharger, which must be fully aware of.

1) Cautions

After stopping the engine, check whether the bolts on pipe connecting section are loose as well as the

connecting condition of vacuum port and modulator, which is connected to the actuator.

During idling of the engine, check for leakage in the connecting section of pipe (hoses and

pipes, duct connections, after the turbocharger) by applying soap water. The leakage condition

in the engine block and turbine housing opening can be determined by the occurrence of

abnormal noise of exhaust.

By running the engine at idle speed, abnormal vibration and noise can be checked. Immediately

stop the engine when abnormal vibration and noise is detected and make thorough inspection

whether the turbocharger shaft wheel has any damages as well as checking the condition of

connections between pipes.

In case where the noise of engine is louder than usual, there is possibility of dampness in the

areas related with air cleaner and engine or engine block and turbocharger. And it could affect

the smooth supply of engine oil and discharge.

Check for damp condition in exhaust gas when there is sign of thermal discoloration or

discharge of carbon in connecting area of the duct.

When the engine rotates or in case where there is change in noise level, check for clogging of

air cleaner or air cleaner duct or if there is any significant amount of dust in the compressor

housing.

During the inspection of center housing, inspect inside of the housing by removing the oil drain

pipe to check for sludge generation and its attachment condition at shaft area or turbine side.

Inspect or replace the air cleaner when the compressor wheel is damaged by inflow of foreign

materials.

Inspect both side of the turbocharger wheel after removing inlet and outlet pipe of the turbocharger.
