11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no
longer drops.
13. Check cooling system for leaks with engine running.
14. Warm up 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.
15. Repeat step 14 three times.
16. If sound is heard, bleed air from cooling system by repeating steps 6 through 11 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed.
2. Install radiator drain plug.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-100, "
Exploded
View".
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-16, "
Component".
3. Fill radiator and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the cooling system. Refer to CO-11, "
Changing Engine Coolant".
8. Repeat steps 1 through 7 until clear water begins to drain from radiator.
RADIATOR
RADIATOR : Checking RadiatorINFOID:0000000001730858
Check radiator for mud or clogging. If necessary, clean radiator as follows.
 Be careful not to bend or damage radiator fins.
 When radiator is cleaned without removal, remove all surrounding parts such as cooling fan, radiator shroud
and horns. Then tape 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 surface 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
(11.8 in).
5. Blow air again into all the radiator core surfaces once per minute until no water sprays out.
FUEL LINES
FUEL LINES : InspectionINFOID:0000000001277610
Inspect fuel lines, filler cap and tank for improper attachment, leaks,
cracks, damage, loose connections, chafing or deterioration.
If necessary, repair or replace damaged parts.

6. Fill radiator and reservoir tank to specified level.
Pour engine coolant through engine coolant filler neck
slowly of less than 2 (2 1/8 US qt, 1-3/4 lmp qt) a minute
to allow air in system to escape.
Use NISSAN Genuine Engine Coolant or equivalent mixed
with water (distilled or demineralized). Fill cooling system
to specification. Refer to MA-19, "
Fluids and Lubricants".
 When engine coolant overflows disconnected heater hose,
connect heater hose, and continue filling the engine coolant, if
heater hose is disconnected.
7. Install radiator cap.
8. Install air duct assembly. Refer to EM-154, "
Component".
9. Warm up 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 the engine.
10. Stop 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.
11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no
longer drops.
13. Check cooling system for leaks with engine running.
14. Warm up 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.
15. Repeat step 14 three times.
16. If sound is heard, bleed air from cooling system by repeating steps 6 through 11 until engine coolant level
no longer drops.
FLUSHING COOLING SYSTEM
1. Install reservoir tank if removed.
2. Install radiator drain plug.
If water drain plug on cylinder block is removed, close and tighten it. Refer to EM-211, "
Compo-
nent".
CAUTION:
Be sure to clean radiator drain plug and install with new O-ring. Refer to CO-40, "
Component".
3. Fill radiator and reservoir tank with water and reinstall radiator cap.
4. Run engine and warm it up to normal operating temperature.
5. Rev engine two or three times under no-load.
6. Stop engine and wait until it cools down.
7. Drain water from the cooling system. Refer to CO-35, "
Changing Engine Coolant".
8. Repeat steps 1 through 7 until clear water begins to drain from radiator.

ENGINE MAINTENANCE (MR18DE)
 Install the air cleaner cover (1) in the direction shown.
ENGINE OIL
ENGINE OIL : InspectionINFOID:0000000001730867
ENGINE OIL LEVEL
NOTE:
Before starting engine, park vehicle on a level surface 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 make sure the engine oil level is within
the range (A) as shown.
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 areas:
 Oil pan (upper and lower)
 Oil pan drain plug
 Oil pressure switch
 Oil filter
 Intake valve timing control solenoid valve
 Front cover
 Mating surface between cylinder block and cylinder head
 Mating surface between cylinder head and rocker cover
 Crankshaft oil seals (front and rear)
 Oil filter (for intake valve timing control)
OIL PRESSURE CHECK
WARNING:
 Be careful not to burn yourself, as engine oil may be hot.
 For engine oil pressure check the transaxle should be in “Neutral position”, and apply the parking
brake securely.2 : Air cleaner filter
