• Check 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.

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

°

C (122

°

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.

ENGINE OIL

ENGINE OIL : Inspection

INFOID:0000000011732678

ENGINE OIL LEVEL

NOTE:
Before starting engine, put vehicle horizontally and check the engine oil level. If engine is already started, stop
it and allow 10 minutes before checking.
1.

Pull out oil level gauge and wipe it clean.

2.

Insert oil level gauge and check that the engine oil level is within
the range (A) shown in the figure.

3.

If it is out of range, adjust it.

ENGINE OIL APPEARANCE

• Check engine oil for white turbidity or heavy contamination.
• If engine oil becomes turbid and white, it is highly probable that it is contaminated with engine coolant.

Repair or replace damaged parts.

ENGINE OIL LEAKAGE 

Check for engine oil leakage around the following area.
• Oil cooler
• Oil level sensor
• Oil temperature sensor
• Oil pan (upper and lower)
• Oil pan drain plug
• Oil pressure sensor
• Oil filter
• Valve timing control cover
• Valve timing control solenoid valve (intake and exhaust)
• Front cover
• Turbocharger
• Turbocharger oil tube (feed and return)
• Turbocharger oil hose
• Mating surface between high pressure pump and camshaft bracket
• Mating surface between cylinder head and camshaft bracket
• Mating surface between cylinder block and cylinder head
• Mating surface between camshaft bracket and rocker cover
• Crankshaft oil seals (front and rear)

OIL PRESSURE CHECK

WARNING:

• Be careful not to get burned, as engine oil may be hot.
• When checking engine oil pressure, shift position should be “Neutral”, and apply parking brake

securely.

4.

Start engine and warm it up to normal operating temperature.

5.

Check oil pressure with engine running under no-load.
NOTE:
When engine oil temperature is low, engine oil pressure becomes high.

If difference is extreme, check oil passage and oil pump for oil leakage.

6.

After the inspections, install oil pressure sensor as follows:

a.

Remove old liquid gasket adhering to oil pressure sensor and engine.

b.

Apply liquid gasket and tighten oil pressure sensor to specification.
Use Genuine RTV Silicon Sealant or equivalent.

c.

Check engine oil level. 

d.

After warming up engine, check that there is no leakage of engine oil with running engine.

ENGINE OIL : Draining

INFOID:0000000011732679

WARNING:

• Be careful not to get burned, as engine oil may be hot.
• Prolonged and repeated contact with used engine oil may cause skin cancer. Try to avoid direct skin

contact with used engine oil. If skin contact is made, wash thoroughly with soap or hand cleaner as
soon as possible. 

1.

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

MA-87,

"ENGINE OIL : Inspection"

.

2.

Never adhere the engine coolant to electronic equipments (alternator etc.).

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

11. Repeat steps 7 through 10 two or more times with radiator cap installed until engine coolant level no

longer drops. 

12. Check cooling system for leakage with engine running.

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

idle up to 3,000 rpm.

14. If flowing noise is heard, bleed air from cooling system by repeating step 7 through 13 until the flowing

noise is longer heard.

ENGINE COOLANT : Flushing

INFOID:0000000011497316

1.

Install reservoir tank if removed and radiator drain plug (1). 

CAUTION:

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

2.

Disconnect heater hose (1) at position (

) in the figure.

• Enhance heater as high as possible.

3.

Fill reservoir tank with water.
• When engine coolant over flows disconnected heater hose, connect heater hose, and continue filling the

engine coolant.

4.

Install radiator cap.

5.

Run the engine and warm it up to normal operating temperature.

6.

Rev the engine two or three times under no-load.

7.

Stop the engine and wait until it cools down.

8.

Drain water from the system. Refer to 

MA-95, "ENGINE COOLANT : Draining"

.

9.

Repeat steps 1 through 8 until clear water begins to drain from radiator.

RESERVOIR TANK CAP

RESERVOIR TANK CAP : Inspection

INFOID:0000000011497318

• 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.
