10. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tem-
perature controller set at several positions between COOL
and HOT.
+Sound may be noticeable at heater water cock.
11. If sound is heard, bleed air from cooling system by repeat-
ing steps 4 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM Ð
1. Fill radiator and reservoir tank with water and reinstall radia-
tor cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water.
6. Repeat steps 1 through 5 until clear water begins to drain
from radiator.
Checking Cooling System
WARNING:
Never remove the radiator cap when the engine is hot; seri-
ous burns could be caused by high pressure fluid escaping
from the radiator.
Wrap a thick cloth around the cap and carefully remove it by
turning it a quarter turn to allow built-up pressure to escape
and then turn the cap all the way off.
CHECKING COOLING SYSTEM HOSES AND CLAMPS
Check hoses and clamps for improper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check radiator for mud or clogging. If necessary, clean radiator
as follows.
+Be careful not to bend or damage the radiator fins.
+When radiator is cleaned without removal, remove all sur-
rounding parts such as cooling fan, radiator shroud and
horns. Then tape the harness and connectors to prevent
water from entering.
1. Apply water by hose to the back side of the radiator core
vertically downward.
2. Apply water again to all radiator core surfaces once per
minute.
3. Stop washing if any stains no longer flow out from the radia-
tor.
4. Blow air into the back side of radiator core vertically down-
ward.
+Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2,
71 psi) and keep distance more than 30 cm (11.8 in).
5. Blow air again into all the radiator core surfaces once per
minute until no water sprays out.

3. Make sure that the spiral cable is in the neutral position.
The neutral position is detected by turning left about 2.5
revolutions from the right end position. Align the two marks
(
,
m).
CAUTION:
+The spiral cable may snap due to steering operation if
the cable is installed in an improper position.
Also, with the steering linkage disconnected, the cable
may snap by turning the steering wheel beyond the lim-
ited number of turns.
The spiral cable can be turned up to about 2.5 turns from
the neutral position to both the right and left.
4. Connect spiral cable connector and tighten with screws.
Install steering column cover.
5. Install steering, wheel setting spiral cable pin guide, and pull
spiral cable through.
6. Connect horn connector and engage spiral cable with pawls
in steering wheel. Move air bag module connector away from
steering wheel lower lid opening.
7. Tighten nut.
