12. Fill reservoir tank up to ªMAXº level, and re-install radiator cap.
13. Run the engine at approximately 2,000 rpm for about oneminute.
14. Stop engine and cool it down, then refill the radiator and the reservoir tank up to the specified level.
Checking Cooling System
CHECKING HOSES
Check hoses for proper attachment, leaks, cracks, damage, loose
connections, chafing and deterioration.
CHECKING RADIATOR CAP
Apply pressure to radiator cap by means of a cap tester to see if it
is satisfactory. Radiator cap relief pressure:78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
CHECKING COOLING SYSTEM FOR LEAKS
Apply pressure to the cooling system by means of a tester to check
for leakage. Testing pressure:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher than the specified pressure may cause radiator dam-
age.
Checking and Replacing fuel filter and Draining
Water
Be careful not to spill fuel in engine compartment. Place a rag
to absorb fuel.
REPLACING FUEL FILTER
1. Remove fuel filter sensor and drain fuel.

4. Remove cylinder block drain plug located at left center of cyl-inder block.
5. Remove reservoir tank and drain coolant.
ÐREFILLING ENGINE COOLANTÐ
6. Install reservoir tank, radiator drain plug, and cylinder block drain plugs.
I Apply sealant to the thread of cylinder block drain plug.
Cylinder block drain plug:
:24-26N ×m (2.4 - 2.7 kg-m, 18 - 19 ft-lb)
7. Move heater TEMP control knob all the way to HOT.
8. Fill radiator with coolant up to the filler neck.
For coolant mixture ratio, refer to MA-19.
9. Fill reservoir tank with coolant up to the MAX level.
Coolant capacity (With reservoir tank):10.6 (9-3/8 Imp qt)
Reservoir tank capacity (for MAX level): 0.75 (5/8 Imp qt)
Pour coolant through coolant filler neck slowly to allow air in
system to escape.
10. Install radiator cap.
11. Warm up engine to normal operating temperature.
12. Run engine at 2,000 rpm for 10 seconds and return to idle speed.
I Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
13. Stop engine and cool it down.
I Cool down using a fan to reduce the time.
14. Remove the radiator cap and check coolant level.
I If necessary, refill radiator up to filler neck with coolant.
15. Refill reservoir tank to Max line with coolant.
16. Repeat step 9 through step 15 two or more times.
17. Warm up engine, and check for sound of coolant flow while running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
I Sound may be noticeable at heater water core.
18. If sound is heard, bleed air from cooling system by repeating steps 11 through 17 until coolant level no longer drops.
I Clean excess coolant from engine.
Checking Cooling System
CHECKING HOSES AND CLAMPS

CHECKING RADIATOR CAP
Apply pressure to radiator cap (side with pressure valve) with cap
tester to see if it is satisfactory.Radiator cap relief pressure:108 - 128 kPa
(1.08 - 1.28 bar, 1.1 - 1.3 kg/cm
2, 16 - 18 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:157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Use of higher pressure than the specified 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 filter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.
2. Remove fuel filter using band-type filter wrench.
3. Remove fuel filter and fuel filter sensor.
CAUTION:
Remove fuel filter without spilling fuel. If spilt, wipe off imme-
diately. Be specially careful not to spill fuel on engine mount
insulator.

Check fluid level.
Fluid level can be checked when the fluid is either hot or cold.
CAUTION:
IDo not overfill.
I Recommended fluid is Automatic Transmission Fluid

TMº type.
I Check lines for improper attachment, leaks, cracks, damage,
loose connections, chafing and deterioration.
Greasing Steering Linkage
Apply multi-purpose grease to point shown in the illustration.
Ventilation Air Filter
FUNCTION
Air inside passenger compartment is kept clean at either recircula-
tion or fresh mode by installing ventilation air filter into cooling unit.
REPLACEMENT PROCEDURES
IRemove glove box.
Refer to BT section.
I Take out ventilation air filter which is secured with one screw,
from cooling unit.
I Replace with new one and reinstall glove box.
