DRIVE BELTSPFP:02117
Checking Drive BeltsEBS00LRA

Before inspecting engine, make sure engine has cooled down;
wait approximately 30 minutes after engine has been stopped.

Visually inspect all belts for wear, damage or cracks on contact-
ing surfaces and edge areas.

When measuring deflection, apply 98 N (10 kg, 22 lb) at the
marked point ( ).
CAUTION:

When checking belt deflection immediately after installa-
tion, first adjust it to the specified value. Then, after turn-
ing crankshaft two turns or more, re-adjust to the
specified value to avoid variation in deflection between
pulleys.

Tighten idler pulley lock nut by hand and measure deflection without looseness.
Belt Deflection:
*: When engine is cold.
Tension AdjustmentEBS00LRB

Adjust belts with the parts shown below.
CAUTION:

When a new belt is installed as a replacement, adjust it to the specified value under “New” value
because of insufficient adaptability with pulley grooves.

If the belt deflection of the current belt is out of the “Limit for re-adjusting”, adjust to the
“Adjusted” value.

When checking belt deflection immediately after installation, first adjust it to the specified value.
Then, after turning crankshaft two turns or more, re-adjust it to the specified value to avoid vari-
ation in deflection between pulleys.

Make sure the belts are fully fitted into the pulley grooves during installation.

Handle with care to avoid smearing the belts with engine oil or engine coolant.

Do not twist or bend the belts with strong force.

EXHAUST MANIFOLD AND TURBOCHARGER

14. Loosen exhaust manifold mounting nuts in reverse order in the
figure.
15. Rotate exhaust manifold and turbocharger assembly so that the rear side (EGR cooler mounting side)
faces upward. And then pull out the assembly from between the engine and the A/C piping.
CAUTION:
Be careful not to deform each turbocharger piping when pulling out the assembly.
INSTALLATION

When a stud bolt is pulled out, tighten it to the following torque:

Tighten the exhaust manifold mounting nuts in the following procedure:
1. Install gasket so that the alignment protrusion faces the No. 4 port. Refer to EM-141, "
Removal and Instal-
lation" .
2. Tighten the nuts in order specified in the figure.
3. Re-tighten the nuts 1 to 4.
4. Install in the reverse order of removal.
INSPECTION AFTER INSTALLATION
Start engine and raise engine speed to check no exhaust gas and engine oil leaks.

TURBINE WHEEL

Make sure that there is no engine oil adhesion.

Make sure that there is no carbon accumulation.

Make sure that blades of turbine wheel are not bent or broken.

Make sure that turbine wheel does not interfere with turbine
housing.
COMPRESSOR WHEEL

Make sure that there is no engine oil adhesion inside the air
inlet.

Make sure that compressor wheel does not interfere with com-
pressor housing.

Make sure that compressor wheel is not bent or broken.
TURBOCHARGER BOOST CONTROL ACTUATOR

Connect the handy vacuum pump to the actuator, and make
sure that the rod strokes smoothly in compliance with the follow-
ing pressure.

lows:

TROUBLE DIAGNOSIS OF TURBOCHARGER
Preliminary check:

Make sure that the engine oil level is between MIN and MAX of the oil level gauge. (When engine oil
amount is more than MAX, engine oil flows into the inlet duct through blow-by gas passage, and turbo-
charger is misjudged malfunction.)

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 malfunction.
Check the other parts again.
