Basic Inspection
Precaution:
Perform Basic Inspection without electrical or mechanical
loads applied;
+Headlamp switch is OFF,
+Air conditioner switch is OFF,
+Rear defogger switch is OFF,
+Steering wheel is in the straight-ahead position, etc.
BEFORE STARTING
1. Check service records for any recent
repairs that may indicate a related
problem, or the current need for sched-
uled maintenance.
2. Open engine hood and check the fol-
lowing:
+Harness connectors for improper con-
nections
+Vacuum hoses for splits, kinks, or
improper connections
+Wiring for improper connections,
pinches, or cuts
3. Using priming pump, bleed air from fuel
system. Refer to ``DRAINING WATER'',
``Checking and Replacing Fuel Filter
and Draining Water'' of ``ENGINE
MAINTENANCE'' in MA section.
CONNECT CONSULT TO THE VEHICLE.
Connect ``CONSULT'' to the data link con-
nector for CONSULT and select
``ENGINE'' from the menu. Refer to
EC-36.
DOES ENGINE START?
Ye s
cNo
Turn ignition switch OFF,
wait 5 seconds and then
start engine. If engine fails
to start, check diagnostic
trouble code (DTC).
Run engine for 10 minutes.
CHECK IDLE SPEED.
----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------
Read engine idle speed in ``DATA
MONITOR'' mode with CONSULT.
--------------------------------------------------------------------------------------------------------------------------------------OR--------------------------------------------------------------------------------------------------------------------------------------
Check idle speed using tachom-
eter tester.

CHECK INJECTION TIMING.
1. Set No. 1 piston at TDC on its com-
pression stroke.
2. Remove injection tubes and air bleeder
on the back of injection pump.
3. Set dial gauge so its indicator points to
somewhere between 1.0 and 2.0 mm
(0.039 and 0.079 in) on the scale.
4. Turn crankshaft 1 turn clockwise and
check that dial gauge indicates the
same value again.
5. Turn crankshaft counterclockwise about
100 degrees, then turn crankshaft
clockwise slowly, and set dial gauge
indicator to 0 mm at the position it
stops.
6. Turn crankshaft clockwise and set the
injection timing mark on the crankshaft
pulley to the timing indicator.
7. Read plunger lift.
Plunger lift:
0.92 0.04 mm (0.0362 0.0016 in)
+When repeating the checking, start
with step 5.
NG
cOK
+Bleed air from fuel sys-
tem.
+After this inspection,
unnecessary diagnostic
trouble code No. might
be displayed.
Erase the stored
memory in ECM.
Refer to ``ON BOARD
DIAGNOSTIC SYSTEM
DESCRIPTION'' (EC-30)
and ``HOW TO ERASE
DTC'' (EC-30).

Checking Cooling System
CHECKING HOSES AND CLAMPS
Check hoses and clamps for proper attachment, leaks, cracks,
damage, loose connections, cha®ng and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap with cap tester to see if it is satis-
factory.
Radiator cap relief pressure:
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Pull the negative-pressure valve to open it. Check that it closes
completely when released.
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system with cap tester to check for
leakage.
Testing pressure:
98 kPa (0.98 bar, 1.0 kg/cm
2, 14 psi)
CAUTION:
Use of higher pressure than the speci®ed value may cause
damage to radiator.
Checking and Replacing Fuel Filter and
Draining Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
CHECKING FUEL FILTER
Check fuel ®lter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.

2. Remove fuel ®lter using band-type ®lter wrench.
Remove fuel ®lter and fuel ®lter sensor.
CAUTION:
Remove fuel ®lter without spilling fuel. If spilt, wipe off imme-
diately. Be specially careful not to spill fuel on engine mount
insulator.
3. Wipe clean fuel ®lter mounting surface on fuel ®lter bracket and
smear a little fuel on rubber seal of fuel ®lter.
4. Screw fuel ®lter on until a slight resistance is felt, then tighten
an additional more than 2/3 of a turn.
5. Install fuel ®lter sensor to new fuel ®lter.
6. Bleed air from fuel line.
Refer to Bleeding Fuel System in EC section.
7. Start engine and check for leaks.
DRAINING WATER
1. Drain water as follows.
Loosen drain cock and drain water.
Loosening drain cock 4 to 5 turns causes water to start drain-
ing. Do not remove drain cock by loosening it excessively.
If water does not drain properly, move the priming pump up and
down.
2. Bleed air.
Checking Fuel Lines
Check fuel lines and tank for proper attachment, leaks, cracks,
damage, loose connections, cha®ng and deterioration.
CAUTION:
Keep clean parts with compressed air when assembling.

Cleaning and Replacing Air Cleaner Filter
VISCOUS PAPER TYPE
The viscous paper type air cleaner ®lter does not require any clean-
ing operation between renewal.
Checking Injection Nozzle
WARNING:
When using nozzle tester, be careful not to allow diesel fuel
sprayed from nozzle to come into contact with your hand or
body, and make sure that your eyes are properly protected.
1. Install nozzle to injection nozzle tester and bleed air from ¯are
nut.
2. Check initial injection pressure by pumping tester handle one
full stroke per second.
Initial injection pressure:
Used nozzle
More than 14,220 kPa
(142.2 bar, 145 kg/cm
2, 2,062 psi)
New nozzle
14,711 - 15,495 kPa
(147.1 - 155.0 bar, 150 - 158 kg/cm
2,
2,133 - 2,247 psi)
+Always check initial injection pressure before installing
new nozzle.
3. Check spray pattern by pumping tester handle one full stroke
per second.
a. If main spray angle is within 30 degrees as shown, injec-
tion nozzle is good.
b. It is still normal even if a thin stream of spray deviates from
main spray (pattern B).
4. If initial injection pressure or injection nozzle is not normal,
adjust or clean injection nozzle.
5. Test again. If it is not corrected, replace nozzle.
Refer to EC section for injection pressure adjustment, clean-
ing and replacement.
