DRIVE BELTS : Checking
INFOID:0000000001095645
WARNING:
Perform this step when engine is stopped.
• Make sure that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
(A) in the figure.
NOTE:
• Check the drive belt auto-tensioner indication when the engine is cold.
• When new drive belt is installed, the indicator (notch on fixed side) should be within the range (B) in the fig-
ure.
• Visually check entire drive belt for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of the possible use range or belt is damaged, replace drive belt.
DRIVE BELTS : Tension Adjustment
INFOID:0000000001095646
Belt tension is not necessary, as it is automatically adjusted by drive belt auto-tensioner.
ENGINE COOLANT

LEVEL
• Check if the reservoir tank engine coolant level is within the “MIN”
to “MAX” when the engine is cool.
• Adjust the engine coolant level as necessary.
• Check that the reservoir tank cap is tightened.
WARNING:
Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escaping
from reservoir tank.

• To check for leakage, fit the adapter to the reservoir tank, and then
connect it to the reservoir tank cap tester [SST: — (M.S.554-07)]
(A) as shown.
WARNING:
Never remove reservoir tank cap when engine is hot. Serious
burns could occur from high-pressure engine coolant escap-
ing from reservoir tank.
CAUTION:
Higher test pressure than specified may cause radiator dam-
age.
• If anything is found, repair or replace damaged parts.
ENGINE COOLANT : Draining
INFOID:0000000001095648
WARNING:
• Never remove reservoir tank cap when engine is hot. Serious burns could occur from high-pressure
engine coolant escaping from reservoir tank.
• Wrap a thick cloth around the reservoir tank cap. Slowly turn it a quarter of a turn to release built-up
pressure. Then turn it all the way.
1.
Disconnect radiator hose (lower) and reservoir tank cap.
When draining all of engine coolant in the system, open water drain plugs on cylinder block. Refer
to
.
CAUTION:
• Perform this step when engine is cold.
• Never spill engine coolant on drive belt.
2.
Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
• Remove of engine mounting insulator (RH) is necessary. Refer to
(M/T
(CVT models).
3.
Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to
MA-35, "RADIATOR : Inspection"
.
ENGINE COOLANT : Refilling
INFOID:0000000001095649
1.
Install reservoir tank if removed.
2.
Connect radiator hose (lower).
If water drain plugs on cylinder block are removed, close and tighten them. Refer to
.
3.
Make sure that each hose clamp has been firmly tightened.
4.
Disconnect heater hose (1) at position (
) in the figure.
• Enhance heater hose as high as possible, keeping heater
hose end above reservoir tank MAX level.
Testing pressure: Refer to

5.
Fill reservoir tank to specified level.
• Pour coolant slowly of less than 2 (1-3/4 lmp qt) a minute
to allow air in system to escape.
• When coolant from heater unit starts to drain, connect
heater hose and continue to fill up to reservoir tank MAX
level.
• Start engine without closing reservoir tank cap.
• Keep engine racing at 1,500 rpm for about 2-3 minutes,
filling reservoir tank up to MAX. Level, if necessary.
• Use Genuine Nissan Engine Coolant or equivalent mixed
with water (distilled or demineralized). Refer to
.
6.
Install reservoir tank cap.
7.
Warm up engine until opening thermostat. Standard for warming-up time is approximately 10 minutes at
2,000 - 2,500 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 engine.
8.
Stop the engine and cool down to less than approximately 50
°
C (122
°
F).
• Cool down using fan to reduce the time.
9.
Refill reservoir tank to “MAX” level line with engine coolant, if necessary.
10. Repeat steps 6 through 9 two or more times with reservoir tank cap installed until reservoir tank level no
longer drops.
11. Check cooling system for leaks with engine running.
12. 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.
13. Repeat step 12 three times.
14. If sound is heard, bleed air from cooling system by repeating step 6 through 9 until reservoir tank level no
longer drops.
15. Check that the reservoir tank cap is tightened.
ENGINE COOLANT : Flushing
INFOID:0000000001095650
1.
Install reservoir tank if removed.
2.
Disconnect radiator hose (lower) and reservoir tank cap.
If water drain plugs on cylinder block are removed, close and tighten them. Refer to
.
3.
Fill reservoir tank with water and reinstall reservoir tank cap.
4.
Run the engine and warm it up to normal operating temperature.
5.
Rev the engine two or three times under no-load.
6.
Stop the engine and wait until it cools down.
7.
Drain water from the system. Refer to
8.
Repeat steps 1 through 7 until clear water begins to drain from radiator.
9.
Check that the reservoir tank cap is tightened.
