Engine Coolant Mixture RatioINFOID:0000000001277601
The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality engine
coolant contains the specific solutions effective for the anti-corrosion
and the anti-freeze function. Therefore, additional cooling system
additives are not necessary.
CAUTION:
 When adding or replacing coolant, be sure to use only Genu-
ine NISSAN Engine Coolant or equivalent in its quality. Genu-
ine NISSAN Engine Coolant is premixed (mixture ratio 50%)
type coolant.
The use of other types of engine coolant may damage your
cooling system.
 When checking the engine coolant mixture ratio by the coolant hydrometer, use the chart below to correct
your hydrometer reading (specific gravity) according to coolant temperature.
Mixed coolant specific gravity
Unit: specific gravity
WARNING:
Never remove the radiator cap when the engine is hot. Serious burns could be caused by high pres-
sure fluid escaping from the radiator. Wait until the engine and radiator cool down.

DRIVE BELTS
DRIVE BELTS : CheckingINFOID:0000000001730848
 Inspection should be done only when engine is cold or over 30
minutes after the engine is stopped.
 Visually check belts for wear, damage, and cracks on inside and
edges.
 Turn crankshaft pulley two time clockwise, and make sure tension on all pulleys is equal before doing the
test.
 When measuring deflection, apply 98 N (10 kg, 22 lb) at the ( ) marked point.
 Measure the belt tension and frequency with acoustic tension gauge (commercial service tool) at the ( )
marked point.
CAUTION:
 When the tension and frequency are measured, the acoustic tension gauge should be used.
 When checking immediately after installation, first adjust it to the specified value. Then, after turning
crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflection
between pulleys.
DRIVE BELTS : Tension AdjustmentINFOID:0000000001730849
CAUTION:
 When belt is replaced with new one, adjust belt tension to the value for “New belt”, because new belt
will not fully seat in the pulley groove.
 When tension of the belt being used exceeds “Limit”, adjust it to the value for “After adjusted”.
 When installing a belt, make sure it is correctly engaged with the pulley groove.
 Never allow oil or engine coolant to get on the belt.
 Never twist or bend the belt strongly.
1. Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.

 When the lock nut is loosened excessively, the idler pulley tilts and the correct tension adjust-
ment cannot be performed. Never loosen it excessively (more than 45 degrees).
 Put a matching mark on the lock nut, and check turning angle with a protractor. Never visually
check the tightening angle.
2. Adjust the belt tension by turning the adjusting bolt.
CAUTION:
 When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, re-adjust to the specified value to avoid variation in deflec-
tion between pulleys.
 When the tension adjustment is performed, the lock nut should be in the condition at step“2”. If
the tension adjustment is performed when the lock nut is loosened more than the standard, the
idler pulley tilts and the correct tension adjustment cannot be performed.
3. Tighten the idler pulley lock nut.
ENGINE COOLANT
ENGINE COOLANT : InspectionINFOID:0000000001730856
LEVEL CHECK
 Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” range when engine is cool.
 Adjust the engine coolant level as necessary.
CHECKING COOLING SYSTEM FOR LEAKS
To check for leaks, apply pressure to the cooling system using suit-
able tool.
WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure coolant escaping from
the radiator.
CAUTION:
Higher pressure than specified may cause radiator damage.
ENGINE COOLANT : Changing Engine CoolantINFOID:0000000001730857
WARNING:
 To avoid being scalded, do not change engine coolant when engine is hot.
 Wrap a thick cloth around radiator cap and carefully remove the cap. First, turn the cap a quarter of a
turn to release built-up pressure. Then turn the cap all the way.
 Be careful not to allow engine coolant to contact drive belt.

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-27, "
Exploded View".
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.

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.
