Inspection
INFOID:0000000012197516
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-11, "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.
Draining
INFOID:0000000012197517
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. Connect drain hose.
• Use a genera-purpose hose with the dimensions show in the
figure.

2. 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
3. Remove reservoir tank if necessary, and drain engine coolant and clean reservoir tank before installing.
4. Check drained engine coolant for contaminants such as rust, corrosion or discoloration. If contaminated,
flush the engine cooling system. Refer to
.
5. Disconnect drain hose.
Refilling
INFOID:0000000012197518
CAUTION:
• Do not reuse O-rings.
• 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-11, "Fluids and Lubricants"
1. Install reservoir tank if removed, and install 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. Remove air duct (suction side). Refer to
4. Disconnect vacuum hose break booster side, and removal vacuum tube from clamp. Refer to
5. Disconnect heater hose (1) at position (
) in the figure.
• Enhance heater hose as high as possible.
6. 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.

ENGINE COOLANT
7. Refill reservoir tank to “MAX” level line with engine coolant.
8. Install air duct (suction side). Refer to
9. Install radiator cap.
10. 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.
11. 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.).
12. Refill reservoir tank to “MAX” level line with engine coolant.
13. Repeat steps 6 through 11 two or more times with radiator cap installed until engine coolant level no
longer drops.
14. Check cooling system for leakage with engine running.
15. 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.
16. Repeat step 15 three times.
17. If sound is heard, bleed air from cooling system by repeating step 6 through 11 until reservoir tank level no
longer drops.
Flushing
INFOID:0000000012197519
1. Install 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. Remove air duct (suction side), air cleaner cover assembly and air cleaner body assembly. Refer to
3. Disconnect vacuum hose break booster side, and remove vacuum tube from clamp. Refer to .
