Precautions
LIQUID GASKET APPLICATION PROCEDURENLLC00141. 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 3.5 to 4.5 mm
(0.138 to 0.177 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.

Precautions
LC-11

Cooling CircuitNLLC0016
SLC317B
System CheckNLLC0017WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could occur from high pressure fluid escaping from the
radiator.
Wrap a thick cloth around the cap. Slowly turn it a quarter turn
to allow built-up pressure to escape. Carefully remove the cap
by turning it all the way.
CHECKING COOLING SYSTEM HOSESNLLC0017S01Check hoses for the following:
+Improper attachment
+Leaks
+Cracks
+Damage
+Loose connections
+Chafing
+Deterioration

LC-12

CHECKING RADIATORNLLC0017S04Check radiator for mud or clogging. If necessary, clean radiator as
follows.
+Be careful not to bend or damage the radiator fins.
+When radiator is cleaned without removal, remove all sur-
rounding parts such as cooling fan, radiator shroud and horns.
Then tape the harness and connectors to prevent water from
entering.
1. Apply water by hose to the back side of the radiator core ver-
tically download.
2. Apply water again to all radiator core surfaces once per
minute.
3. Stop washing if any stains no longer flow out from the radia-
tor.
4. Blow air into the back side of radiator core vertically download.
+Use compressed air lower than 490 kPa (4.9 bar, 5 kg/cm
2,71
psi) and keep distance more than 30 cm (11.8 in).
5. Blow air again into all the radiator core surfaces once per
minute until no water sprays out.
SLC613-A
CHECKING RADIATOR CAPNLLC0017S03To check radiator cap, apply pressure to cap with a tester.
Radiator cap relief pressure:
Standard
78-98kPa
(0.78 - 0.98 bar, 0.8 - 1.0 kg/cm
2, 11 - 14 psi)
Limit
59-98kPa
(0.59 - 0.98 bar, 0.6 - 1.0 kg/cm
2,9-14psi)
SMA967B
Pull the negative pressure valve to open it.
Check that it closes completely when released.
SLC756AA
CHECKING COOLING SYSTEM FOR LEAKSNLLC0017S02To check for leakage, apply pressure to the cooling system with a
tester.
Testing pressure:
157 kPa (1.57 bar, 1.6 kg/cm
2, 23 psi)
CAUTION:
Higher pressure than specified may cause radiator damage.

CAUTION:
+When removing water pump assembly, be careful not to
get coolant on drive belt.
+Water pump cannot be disassembled and should be
replaced as a unit.
+After installing water pump, and check for leaks using
radiator cap tester.
1. Drain engine coolant.
Refer to LC-19, ªChanging Engine Coolantº.
2. Remove drive belts and idler pulley.
3. Loosen water pump pulley bolts.
4. Remove water pump pulley.
5. Remove front right wheel.
6. Remove front right undercover and front right fender protector.
7. Remove water pump bolts.
8. Remove water pump.
9. Reinstall parts in reverse order of removal.

Ð REFILLING ENGINE COOLANT ÐNLLC0037S021. Install reservoir tank, lower radiator hose and cylinder block
drain plug.
+Apply sealant to the thread of cylinder block drain plug.
: 35 - 44 N´m (3.50 - 4.50 kg-m, 26 - 32 ft-lb)
2. Fill radiator slowly with coolant until coolant spills from the air
relief plug, then install air relief plug.
Air relief plug:
: 6.7 - 7.8 N´m (0.68 - 0.80 kg-m, 59 - 69 in-lb)
+Use genuine Nissan anti-freeze coolant or equivalent.

CANTSº.
Coolant capacity:

With reservoir tank 6.75 (6)
Reservoir tank 0.7 (5/8)
+Pour coolant through coolant filler neck slowly to allow air
in system to escape.
3. Fill radiator and reservoir tank to specified level.
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 level line with coolant.
8. Repeat steps 4 through 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 4 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM ÐNLLC0037S031. 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.
