DRIVE BELT
DRIVE BELT : Checking
INFOID:0000000006057327
• 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 check 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, readjust to the specified value to avoid variation in deflection between
pulleys.
DRIVE BELT : Tension Adjustment
INFOID:0000000006057328
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, check 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.
Remove front fender protector (RH). Refer to
EXT-17, "FENDER PROTECTOR : Exploded View"
.
2.
Loosen the idler pulley lock nut (A) from the tightening position
with the specified torque by 45 degrees.
CAUTION:
• 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 (A), and check turning angle with a protractor. Never visu-
ally check the tightening angle.
3.
Adjust the belt tension by turning the adjusting bolt (B). Refer to
MA-10, "DRIVE BELT : Checking"
.
CAUTION:
• When checking immediately after installation, first adjust it to the specified value. Then, after
turning crankshaft two turns or more, readjust 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.
4.
Tighten the lock nut.
ENGINE COOLANT
ENGINE COOLANT : Inspection
INFOID:0000000006057336
LEVEL
• Check that the reservoir tank engine coolant level is within the
“MIN” to “MAX” when the engine is cool.
• Adjust the engine coolant level if necessary.
LEAKAGE
• To check for leakage, apply pressure to the cooling system with the
radiator cap tester (commercial service tool) (A) and the radiator
cap tester adapter (commercial service tool) (B).
WARNING:
Never remove radiator cap when engine is hot. Serious burns
may occur from high-pressure engine coolant escaping from
radiator.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
NOTE:
In a case that engine coolant decreases, replenish radiator with engine coolant.
• If anything is found, repair or replace damaged parts.
ENGINE COOLANT : Draining
INFOID:0000000006057337
WARNING:
• Never remove radiator cap when engine is hot. Serious burns may occur from high-pressure engine
coolant escaping from radiator.
• Wrap a thick cloth around the radiator cap. Slowly turn it a quarter of a turn to release built-up pres-
sure. Then turn it all the way.

ENGINE MAINTENANCE
1.
Open radiator drain plug (A) at the bottom of radiator, and then
remove radiator cap.
CAUTION:
Perform this step when engine is cold.
• When draining all of engine coolant in the system, open water
drain plugs on cylinder block. Refer to EM.
2.
Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
Refer to
3.
Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to
.
ENGINE COOLANT : Refilling
INFOID:0000000006057338
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 EM.
2.
Check that each hose clamp has been firmly tightened.
3.
Remove air duct inlet and air cleaner assembly. Refer to
EM-24, "Removal and Installation"
4.
Disconnect heater hose (1) at position (
) in the figure.
• Enhance heater hose as high as possible.
5.
Fill radiator (1) to specified level.
CAUTION:
Never adhere the engine coolant to electronic equipments
(alternator etc.).
• Pour coolant slowly of less than 2 (2-1/8 US qt, 1-3/4
Imp qt) a minute to allow air in system to escape.
• When engine coolant overflows disconnected heater
hose, connect heater hose, and continue filling the engine
coolant.
• Use Genuine NISSAN Engine Coolant or equivalent in its
quality mixed with water (distilled or demineralized). Refer

6.
Refill reservoir tank to “MAX” level line with engine coolant.
7.
Install air duct (between air cleaner case and electric throttle control actuator). Refer to
8.
Install radiator cap.
9.
Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at
3,000 rpm.
• 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.
10. 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.
CAUTION:
Never adhere the engine coolant to electronic equipments (alternator etc.).
11. Refill reservoir tank to “MAX” level line with engine coolant.
12. Repeat steps 5 through 10 two or more times with radiator cap installed until engine coolant level no
longer drops.
13. Check cooling system for leakage with engine running.
14. 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.
15. Repeat step 14 three times.
16. If sound is heard, bleed air from cooling system by repeating step 5 through 10 until reservoir tank level no
longer drops.
