Checking Drive BeltsEBS00LRA
●Before inspecting the engine, make sure the engine has cooled
down; wait approximately 30 minutes after the 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 the 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 value specified 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 cooling water etc.
●Do not twist or bend the belts with strong force.

EXHAUST MANIFOLD AND TURBOCHARGER
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.

CHECKING COMPRESSION PRESSURE
1. Warm up engine thoroughly. Then, stop it.
2. Using CONSULT-II, make sure no error codes are indicated for self-diagnosis items. Refer to EC-1412,
"Basic Inspection" .
●Do not disconnect CONSULT-II until the end of this operation; it will be used to check engine rpm and
for error detection at the end of this operation.
3. Disconnect the negative battery terminal.
4. Remove charge air cooler. Refer to EM-122, "
Removal and Installation"
5. To prevent fuel from being injected during inspection, remove
fuel supply pump fuse [ENG CONT (20A)] from fuse box on the
left side of engine compartment.
●Among marks on fuse box, [ENG CONT 2 (20A)] is for fuel
supply pump fuse.
6. Remove glow plugs from all the cylinders. Refer to EM-138,
"Removal and Installation" .
CAUTION:
●Before removal, clean the surrounding area to prevent
entry of any foreign materials into the engine.
●Carefully remove glow plugs to prevent any damage or
breakage.
●Handle with care to avoid applying any shock to glow plugs.
7. Install adapter to installation holes of glow plugs and connect
compression gauge for diesel engine.
8. Connect battery negative terminal.
9. Set the ignition switch to “START” and crank. When gauge
pointer stabilizes, read compression pressure and engine rpm.
Repeat the above steps for each cylinder.
●Always use a fully-charged battery to obtain specified engine
speed.
Compression pressure
Unit: kPa (bar, kg/cm2 , psi)/rpm
●When engine rpm is out of the specified range, check the specific gravity of battery liquid. Measure
again under corrected conditions.
●If engine rpm exceeds the limit, check valve clearance and combustion chamber components (valves,
valve seats, cylinder head gaskets, piston rings, pistons, cylinder bores, cylinder block upper and lower
surfaces) and measure again.
●If compression pressure is low in some cylinders, apply engine oil from glow plug installation hole. Then
check pressure again.
–If compression pressure becomes normal after applying engine oil, piston ring may be worn or dam-
aged. Check piston ring for malfunction. If any, replace piston ring.
–If compression pressure is still low after applying engine oil, valve may be malfunctioning. Check valve
for malfunction. If contact malfunction is found, replace valve or valve seat.
●If compression pressure in adjacent two cylinders is low after applying engine oil, pressure may be
leaking from gasket. In this case, replace cylinder head gasket.
10. Complete this operation as follows:

EC
When the engine coolant temperature reaches an abnormally high temperature condition, a malfunction is
indicated.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant following the procedure in the MA-27,
"Changing Engine Coolant" . Also, replace the engine oil.
1. Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure to
use coolant with the proper mixture ratio. Refer to MA-18, "
Engine Coolant Mixture Ratio" .
2. After refilling coolant, run engine to ensure that no water-flow noise is emitted.
Overall Function CheckEBS004QV
Use this procedure to check the overall function of the cooling fan. During this check, a DTC might not be con-
firmed.
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator.
Wrap a thick cloth around the cap. Carefully remove the cap by turning it a quarter turn to allow built-
up pressure to escape. Then turn the cap all the way off.
WITH CONSULT-II
1. Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to EC-1511,
"Diagnostic Procedure" .
2. Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to EC-1511,
"Diagnostic Procedure" .
3. Turn ignition switch “ON”.
4. Perform “COOLING FAN” in “ACTIVE TEST” mode with CON-
SULT-II and make sure that cooling fans operate when touching
“HIGH” or “LOW”.
If NG, go to EC-1511, "
