8. Fill radiator and reservoir tank to specified level.
9. Start engine without installing radiator cap and warm it up at
2,000 rpm until radiator lower hose becomes hot.
If coolant level becomes low, refill coolant until coolant level
does not change.
If coolant overflows radiator filler hole, install filler cap.
10. Run engine at 2,500 prm for 10 seconds and return to idle
speed.
Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
11. Stop engine and cool it down.
Cool down using a fan to reduce the time.
If necessary, refill radiator up to filler neck.
12. Refill reservoir tank to Max line with coolant.
13. Repeat steps 9 through 12 two or more times with radiator
cap installed until coolant level no longer drops.
14. Check cooling system for leaks with engine running.
15. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tem-
perature control set at several positions between COOL and
HOT.
Sound may be noticeable at heater water cock.
16. If the sound is heard, bleed air from cooling system by
repeating steps 9 through 12 until coolant level no longer
drops.
—FLUSHING COOLING SYSTEM—
1. Open air relief plug.
2. Fill radiator with water until water spills from air relief hole,
then reinstall air relief plug.
Air relief plug:
:7-8N·m (0.7 - 0.8 kg-m, 5,1 - 5.8 ft-lb)
Fill radiator and reservoir tank with water and reinstall radia-
tor cap.
3. Run engine and warm it up sufficiently.
4. Rev engine 2 or 3 times under no-load.
Make sure that blower fan is“OFF”.
5. Stop engine and wait until it cools down.
6. Drain water.
7. Repeat steps 1 through 6 until clear water begins to drain
from radiator.
Checking Cooling System
CHECKING HOSES
Check hoses for proper attachment and for 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.
