10. Install air cleaner case (LH). Refer to 

EM-25, "Exploded View"

.

11. Install radiator cap.
12. Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at

3,000 rpm.
• Make sure thermostat opening condition by touching radiator hose (lower) to see a flow of warm water.

CAUTION:

Watch water temperature gauge so as not to overheat engine.

13. Stop the engine and cool down to less than approximately 50

°

C (122

°

F).

• Cool down using fan to reduce the time.
• If necessary, refill radiator up to filler neck with engine coolant.

14. Refill reservoir tank to “MAX” level line with engine coolant.

15. Repeat steps 11 through 14 two or more times with radiator cap installed until engine coolant level no

longer drops. 

16. Check cooling system for leaks with engine running.

17. Warm up the engine, and check for sound of engine coolant flow while running engine from idle up to

3,000 rpm with heater temperature controller set at several position between “COOL” and “WARM”.
• Sound may be noticeable at heater unit.

18. Repeat step 17 three times.
19. If sound is heard, bleed air from cooling system by repeating step 6, and steps from 11 to 18 until engine

coolant level no longer drops. 

20. Check that the reservoir tank cap is tightened.

1.

Install reservoir tank if removed, and radiator drain plug.

CAUTION:

Be sure to clean drain plug and install with new O-ring.

If water drain plugs on cylinder block are removed, close and tighten them. Refer to

ting"

.

2.

Remove air relief plug (1) on heater hose.

3.

Remove air relief plug (2) on radiator.

4.

Fill radiator with water until water spills from the air relief holes, then close air relief plugs. Fill radiator and
reservoir tank with water and reinstall radiator cap.

Warm up the engine, and check for engine oil leakage from engine components. Refer to 

LU-7, "Inspec-

tion"

.

2.

Stop the engine and wait for 10 minutes.

Engine oil specification and viscosity: Refer to 

MA-16, "ENGINE OIL : Refilling"

CAUTION:

• When filling engine oil, do not pull out oil level gauge.
• The refill capacity depends on the engine oil temperature and drain time. Use these specifica-

tions for reference only.

• Always use oil level gauge to determine the proper amount of engine oil in engine.

3.

Warm up the engine and check area around drain plug and oil filter for engine oil leakage.

4.

Stop the engine and wait for 10 minutes.
