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

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

longer drops. 

15. Check cooling system for leakage with engine running.

16. Warm up the engine, and check for flowing noise while repeat at least three time slow acceleration from

idle up to 3,000 rpm.

17. If flowing noise is heard, bleed air from cooling system by repeating step 10 through 16 until flowing noise

is no longer heard.

RADIATOR CAP

RADIATOR CAP : Inspection

INFOID:0000000011732688

• Fit the adapter to the reservoir tank cap tester [SST: — (M.S. 554-

07)] (A) as shown.

• When connecting the reservoir tank cap to the reservoir tank cap

tester, apply water or LLC to the reservoir tank cap seal part.

• Check reservoir tank cap relief pressure.

• Replace the reservoir tank cap if the engine coolant passes

through it, or if any fur signs is detected.

CAUTION:

When installing reservoir tank cap, thoroughly wipe out the res-
ervoir tank filler neck to remove any waxy residue or foreign
material.

RADIATOR

RADIATOR : Inspection

INFOID:0000000011732687

Check radiator for mud or clogging. If necessary, clean radiator as follows.

CAUTION:

• Never bend or damage radiator fins.
• When radiator is cleaned without removal, remove all surrounding parts such as radiator cooling fan

assembly and horns. Then tape harness and harness 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 radiator.

4.

Blow air into the back side of radiator core vertically downward.
• Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm

2

, 71 psi) and keep distance more than 30 cm

(11.81 in). 

5.

Blow air again into all the radiator core surfaces once per minute until no water sprays out.
