For more information, refer to ªMAIN 11 CAUSES
OF OVERHEATINGº, EC-3348.
CAUTION:
When a malfunction is indicated, be sure to replace the coolant. Refer to MA section, ªChanging Engine
Coolantº. Also, replace the engine oil.
1) Fill radiator with coolant up to specified level with a filling speed of 2 liters per minute. Be sure
to use coolant with the proper mixture ratio. Refer to MA section, ªAnti-freeze Coolant Mixture
Ratioº.
2) After refilling coolant, run engine to ensure that no water-flow noise is emitted.

Overall Function CheckNEEC1535WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator.
Wrap a thick cloth around cap. Carefully remove the cap by
turning it a quarter turn to allow built-up pressure to escape.
Then turn the cap all the way off.
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is below
the proper range, skip the following steps and go to ªDiagnos-
tic Procedureº, EC-3345.
2) Confirm whether customer filled the coolant or not. If customer
filled the coolant, skip the following steps and go to ªDiagnos-

2) Confirm whether customer filled the coolant or not. If cus-
tomer filled the coolant, skip the following steps and go to
ªDiagnostic Procedureº, EC-3494.
3) Turn ignition switch ªONº.
4) Perform ªCOOLING FANº in ªACTIVE TESTº mode with

touching ªONº or ªOFFº.
If NG, go to ªDiagnostic Procedureº, EC-3494.
WITHOUT CONSULT-II
1) Check the coolant level in the reservoir tank and radiator.
Allow engine to cool before checking coolant level.
If the coolant level in the reservoir tank and/or radiator is
below the proper range, skip the following steps and go to
ªDiagnostic Procedureº, EC-3494.
2) Confirm whether customer filled the coolant or not. If cus-
tomer filled the coolant, skip the following steps and go to

RECOMMENDED FLUIDS AND LUBRICANTS
MA-3008

3. Remove reservoir tank, drain coolant, then clean reservoir
tank.
+Be careful not to allow coolant to contact drive belts.
4. Remove drain plug of cylinder block.
5. Check drained coolant for contaminants such as rust, corro-
sion or discoloration. If contaminated flush engine cooling
system, refer to MA-3016, ªFLUSHING COOLING SYS-
TEMº.
Ð REFILLING ENGINE COOLANT Ð
1. Install reservoir tank, radiator drain plug and cylinder block
drain plug.
+Apply sealant to the thread of cylinder block drain plugs.
:8-11Nzm (0.8 - 1.2 kg-m, 70 - 104 in-lb)
2. Fill radiator with coolant to the filler neck of the radiator cap
at a rate of 2!(1-3/4 Imp qt)/min or lower.
+Use genuine Nissan Anti-freeze Coolant or equivalent
mixed with water (distilled or demineralized).
Refer to MA-3008, ªRECOMMENDED FLUIDS AND LUBRI-
CANTSº.
CAUTION:
If the filling rate is too fast, this could lead to air being mixed
in the coolant. Be sure to fill the coolant slowly according
to the rate indicated above.
Engine coolant capacity (With reservoir tank):
8.6!(7-5/8 Imp qt)
Reservoir tank capacity:
0.7!(5/8 Imp qt)
3. Fill reservoir tank to the MAX level.
4. Warm up engine to normal operating temperature without
radiator cap installed.
+If coolant overflows radiator filler hole, install radiator
cap.
5. Run engine at 3,000 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 tem-
perature 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 repeat-
ing steps 4 through 7 until coolant level no longer drops
+Clean excess coolant from engine.
Ð FLUSHING COOLING SYSTEM Ð
1. Fill radiator and reservoir tank with water and reinstall radia-
tor cap.
2. Run engine and warm it up to normal operating temperature.
3. Rev engine two or three times under no-load.
4. Stop engine and wait until it cools down.
5. Drain water.
6. Repeat steps 1 through 5 until clear water begins to drain
from radiator.
Checking Cooling System
WARNING:
Never remove the radiator cap when the engine is hot; seri-
ous burns could be caused by high pressure fluid escaping
from the radiator.
Wrap a thick cloth around the cap and carefully remove it by
turning it a quarter turn to allow built-up pressure to escape
and then turn the cap all the way off.
CHECKING COOLING SYSTEM HOSES AND CLAMPS
Check hoses and clamps for improper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.
CHECKING RADIATOR
Check 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
vertically downward.
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 down-
ward.
+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.
