WARNING:
Perform this step when engine is stopped.
• Check that the indicator (notch on fixed side) of drive belt auto-tensioner is within the possible use range
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
in the fig-
ure.
• Visually check entire drive belts for wear, damage or cracks.
• If the indicator (notch on fixed side) is out of the possible use range or belts is damaged, replace belts.

INFOID:0000000011009150
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.
CAUTION:
Refill Genuine NISSAN Long Life Antifreeze/Coolant (blue) or
equivalent in its quality mixed with water (distilled or deminer-
alized). Refer to
MA-23, "Fluids and Lubricants"
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
engine cooling system.
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:0000000011009151
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.
1.
Remove engine under cover. Refer to
EXT-39, "ENGINE UNDER COVER : Exploded View"
2.
Open radiator drain plug
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
3.
Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.

ENGINE MAINTENANCE (MR20DD)
• Move reservoir tank
, and then remove it numerical order as
shown in the figure.
4.
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:0000000011009152
CAUTION:
• Do not put additive such as waterleak preventive, since it may cause cooling waterway clogging.
• When refilling use Genuine NISSAN Long Life Antifreeze/Coolant (blue) or equivalent in its quality
mixed with water (distilled or demineralized). Refer to
MA-23, "Fluids and Lubricants"
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
.
2.
Check that each hose clamp has been firmly tightened.
3.
Fill radiator to specified level.
CAUTION:
Never adhere the engine coolant to electronic equipments
(alternator etc.).
• Pour coolant slowly of less than 2 (1-3/4 Imp qt) a
minute to allow air in system to escape.
4.
Refill reservoir tank to “MAX” level line with engine coolant.
5.
Install radiator cap.
6.
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.

7.
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.).
8.
Refill reservoir tank to “MAX” level line with engine coolant.
9.
Repeat steps 5 through 8 two or more times with radiator cap installed until engine coolant level no longer
drops.
10. Check cooling system for leakage with engine running.
11. 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.
12. Repeat step 11 three times.
13. If sound is heard, bleed air from cooling system by repeating step 5 through 8 until reservoir tank level no
longer drops.
ENGINE COOLANT : Flushing
INFOID:0000000011009153
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
2.
Fill radiator and reservoir tank with water and reinstall radiator cap.
3.
Run the engine and warm it up to normal operating temperature.
4.
Rev the engine two or three times under no-load.
5.
Stop the engine and wait until it cools down.
6.
Drain water from the system. Refer to
7.
Repeat steps 1 through 6 until clear water begins to drain from radiator.
RADIATOR CAP
RADIATOR CAP : Inspection
INFOID:0000000011009157
• Check valve seat
of radiator cap.
- Check that valve seat is swollen to the extent that the edge of the
plunger
cannot be seen when watching it vertically from the top.
- Check that valve seat has no soil and damage.
- Check that there is no dirt or damage on the valve seat of radiator
cap negative-pressure valve.
- Check that there are no unusualness in the opening and closing
conditions of negative-pressure valve.
