TURBINE WHEEL
●Check that there is no engine oil adhesion.
●Check that there is no carbon accumulation.
●Check that blades of the turbine wheel are not bent or broken.
●Check that the turbine wheel does not interfere with the turbine
housing.
COMPRESSOR WHEEL
●Check that there is no engine oil adhesion inside the air inlet.
●Check that the compressor wheel does not interfere with the
compressor housing.
●Check that the wheel is not bent or broken.
WASTEGATE VALVE ACTUATOR
●Connect the handy pump to the actuator, and check that the rod
strokes smoothly in compliance with the following pressure.
●Pressure to be applied at actuator part to move rod end as fol-
lows:

TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:
●Check that the engine oil level is between MIN and MAX of the dipstick. (When the engine oil amount is
more than MAX, the engine oil flows into the inlet duct through the blow-by gas passage, and the turbo-
charger is misjudged failure.)
●Ask the customer if he/she always runs the vehicle in idle engine speed to cool the engine oil down after
driving.
●Replace the turbocharger assembly when any malfunction is found after unit inspections specified in the
table below.
●If no malfunction is found after the unit inspections, judge that the turbocharger body has no failure. Check
the other parts again.

b. Apply a continuous bead of liquid gasket to mating surface of
lower oil pan.
Use Genuine Liquid Gasket or equivalent.
●Be sure liquid gasket is 3.5 to 4.5 mm (0.138 to 0.177 in)
wide.
●Attaching should be done within 5 minutes after coating.
8. Install oil pan drain plug.
●Refer to illustration of components parts for installation direc-
tion of washer.
9. Install in the reverse order of removal after this step.
●Pour engine oil or start engine at least 30 minutes after
oil pan is installed.
INSPECTION AFTER INSTALLATION
●Check engine oil level. Refer to LU-18, "ENGINE OIL" .
●Check for leakage of engine oil when engine is warmed.
