2. Fill radiator slowly with coolant until coolant spills from the air
relief plug, then install air relief plug.
3. Fill radiator and reservoir tank to specified level.
Air relief plug:
: 7.2 - 9.8 N´m (0.73 - 1.0 kg-m, 63.4 - 86.8 in-lb)
+Use genuine Nissan anti-freeze coolant or equivalent.
+Pour coolant through coolant filler neck slowly to allow air
in system to escape.
Refer to ªRECOMMENDED FLUIDS AND LUBRICANTSº,
MA-20.
Coolant capacity (With reservoir tank):
6.75!(6 Imp qt)
Reservoir tank capacity (for MAX level):
0.7!(5/8 Imp qt)
4. Warm up engine to normal operating temperature without
radiator cap installed.
+If coolant overflows radiator filler hole, install filler cap.
5. Run engine at 2,500 rpm for 10 seconds and return to idle
speed with radiator cap installed.
+Repeat two or three times.
Watch coolant temperature gauge so as not to overheat the
engine.
6. Stop engine and cool it down.
+Cool down using a fan to reduce the time.
+If necessary, refill radiator up to filler neck with coolant.
7. Refill reservoir tank to Max line with coolant.
8. Repeat step 5 through step 7 two or more times with radiator
cap installed until coolant level no longer drops.
9. Check cooling system for leaks with engine running.
10. Warm up engine, and check for sound of coolant flow while
running engine from idle up to 3,000 rpm with heater tempera-
ture controller set at several positions between COOL and
HOT.
+Sound may be noticeable at heater water cock.
11. If sound is heard, bleed air from cooling system by repeating
steps 5 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM ÐNLLC0108S031. Open air relief plug.
2. Fill radiator with water until water spills from the air relief hole,
then close air relief plug. Fill radiator and reservoir tank with
water and reinstall radiator cap.
3. Run engine and warm it up to normal operating temperature.
4. Rev engine two or three times under no-load.
5. Stop engine and wait until it cools down.
6. Drain water.
7. Repeat steps 1 through 6 until clear water begins to drain from
radiator.

Precautions
LIQUID GASKET APPLICATION PROCEDURENLLC00391. Use a scraper to remove all traces of old liquid gasket from
mating surfaces and grooves. Also, completely clean any oil
from these areas.
2. Apply a continuous bead of liquid gasket to mating surfaces.
(Use Genuine Liquid Gasket or equivalent.)
+For oil pan, be sure liquid gasket diameter is 4.0 to 5.0 mm
(0.157 to 0.197 in).
+For areas except oil pan, be sure liquid gasket diameter is 2.0
to 3.0 mm (0.079 to 0.118 in).
3. Apply liquid gasket around the inner side of bolt holes (unless
otherwise specified).
4. Assembly should be done within 5 minutes after coating.
5. Wait at least 30 minutes before refilling engine oil and engine
coolant.

Changing Engine OilNLLC0074WARNING:
+Be careful not to burn yourself, as the engine oil is hot.
+Prolonged and repeated contact with used engine oil may
cause skin cancer; try to avoid direct skin contact with
used oil. If skin contact is made, wash thoroughly with
soap or hand cleaner as soon as possible.
1. Warm up engine, and check for oil leakage from engine com-
ponents.
2. Stop engine and wait more than 10 minutes.
3. Remove drain plug and oil filler cap.
4. Drain oil and refill with new engine oil.
Oil Specification and Viscosity:
+API grade CF-4
+ACEA grade B1-98, B3-98

CAUTION:
+Be sure to clean drain plug and install with new washer.
Drain plug:

+The refill capacity depends on the oil temperature and
drain time. Use these specifications for reference only.
Always use the dipstick to determine when the proper
amount of oil is in the engine.
5. Check oil level.
6. Start engine and check area around drain plug and oil filter for
oil leakage.
7. Run engine for a few minutes, then turn it off. After several
minutes, check oil level.
