3. TROUBLESHOOTING
The followings are cautions to take in handling defects of turbocharger, which must be fully aware
of.
1) Cautions
1. 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.
2. 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.
3. 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.
4. 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.
5. Check for damp condition in exhaust gas when there is sign of thermal
discoloration or discharge of carbon in connecting area of the duct.
6. 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.
7. 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.
8. Inspect or replace the air cleaner when the compressor wheel is damaged by
inflow of foreign materials.
9. Inspect both side of the turbocharger wheel after removing inlet and outlet pipe of
the turbocharger.
- Is the rotation smooth when the rotor is rotated by hand?
- Is the movement of bearing normal?
- Inspect whether there has been any signs of interference between two wheels.
It's important not to drive the engine when the intake manifold hose has been removed.
