Anti-freeze Coolant Mixture Ratio
The engine cooling system is ®lled at the factory with a high-quality,
year-round, anti-freeze coolant solution. The anti-freeze solution
contains rust and corrosion inhibitors. Therefore, additional cooling
system additives are not necessary.
CAUTION:
When adding or replacing coolant, be sure to use only an eth-
ylene glycol anti-freeze with the proper mixture ratio. See the
following examples:

4. Add engine oil.
Refer to Changing Engine Oil.
+Clean excess oil from engine.
Changing Engine Coolant
WARNING:
To avoid the danger of being scalded, never change the cool-
ant when the engine is hot.
ÐDRAINING ENGINE COOLANTÐ

Pour coolant through coolant ®ller neck slowly to allow air in
system to escape.
12. Warm up engine to normal operating temperature.
13. Run engine at 2,000 rpm for 10 seconds and return to idle
speed.
+Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
14. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
15. Remove the radiator ®ller cap and check coolant level.
+If necessary, re®ll radiator up to ®ller neck with coolant.
16. Re®ll reservoir tank to Max line with coolant.
17. Repeat step 12 through step 16 two or more times.
18. Warm up engine, and check for sound of coolant ¯ow while
running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
+Sound may be noticeable at heater water cock.
19. If sound is heard, bleed air from cooling system by repeating
steps 12 through 16 until coolant level no longer drops.

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.

Checking Idle Speed
Inspection should be carried out with gears in ``Neutral'' and
with air conditioner and other electrical loads off.
1. Warm up engine until engine coolant temperature indicator
points to the middle of gauge.
2. Attach a diesel tachotester's pick-up to No. 1 fuel injection tube.
3. Race engine two or three times and check idle speed.
