*3: Do not mix automatic transmission fluid and gear oil.
*4: Never use API CG-4.
*5: Use Genuine Nissan Anti-freeze Coolant (L250) or equivalent in its quality, in order to avoid possible aluminum corrosion within
the engine cooling system caused by the use of non-genuine engine coolant.
Note that any repairs for the incidents within the engine cooling system while using non-genuine engine coolant may
not be covered by the warranty even if such incidents occurred during the warranty period.

Engine Coolant Mixture Ratio
The engine cooling system is filled at the factory with a high-quality,
year-round and extended life engine coolant. The high quality
engine coolant contains the specific solutions effective for the anti-
corrosion and the anti-freeze function. Therefore, additional cooling
system additives are not necessary.
CAUTION:
IWhen adding or replacing coolant, be sure to use only
Genuine Nissan Anti-freeze Coolant (L2N) or equivalent.
Because L2N is premixed type coolant (Mixture ratio 50%).
The use of other types of engine coolant may damage your
cooling system.
I When checking the engine coolant mixture ratio by the coolant
hydrometer, use the chart below to correct your hydrometer
reading (specific gravity) according to coolant temperature.
Mixed coolant specific gravity

WARNING:
Never remove the radiator cap when the engine is hot. Serious
burns could be caused by high pressure fluid escaping from
the radiator. Wait until the engine and radiator cool down.

Preparation
1. Make sure that injection timing is correct.
2. Make sure that injection nozzle are in good condition.
3. Make sure that the following parts are in good condition.
IAir cleaner clogging
I Glow system
I Engine oil and coolant levels
I Valve clearance
I Air intake system (Oil filler cap, oil level gauge, etc.)
4. Set shift lever in ªNeutralº position. Engage parking brake and lock both front and rear wheels with wheel chocks.
5. Turn off air conditioner, lights and accessories.
I Warm up engine until water temperature indicator points to middle of gauge.
I Lights, heater fan and all accessories are off.
I Attach tachometer's pick-up to No. 1 fuel injection tube.
In order to take accurate reading of engine rpm, remove clamps that secure No. 1 fuel injection tube.
Start engine.

Run engine at about 2,000 rpm for
about 2 minutes under no-load.
Run engine for one minute at idle
speed.F
Check idle speed.

END
I
Race engine two or three times and allow engine to return to idle speed. If idle speed is not within
the specified range, check acceleration linkage for binding and correct it if necessary.

4. Remove cylinder block drain plug located at left center of cyl-inder block.
5. Remove reservoir tank and drain coolant.
ÐREFILLING ENGINE COOLANTÐ
6. Install reservoir tank, radiator drain plug, and cylinder block drain plugs.
I Apply sealant to the thread of cylinder block drain plug.
Cylinder block drain plug:
:24-26N ×m (2.4 - 2.7 kg-m, 18 - 19 ft-lb)
7. Move heater TEMP control knob all the way to HOT.
8. Fill radiator with coolant up to the filler neck.
For coolant mixture ratio, refer to MA-19.
9. Fill reservoir tank with coolant up to the MAX level.
Coolant capacity (With reservoir tank):10.6 (9-3/8 Imp qt)
Reservoir tank capacity (for MAX level): 0.75 (5/8 Imp qt)
Pour coolant through coolant filler neck slowly to allow air in
system to escape.
10. Install radiator cap.
11. Warm up engine to normal operating temperature.
12. Run engine at 2,000 rpm for 10 seconds and return to idle speed.
I Repeat 2 or 3 times.
Watch coolant temperature gauge so as not to overheat the
engine.
13. Stop engine and cool it down.
I Cool down using a fan to reduce the time.
14. Remove the radiator cap and check coolant level.
I If necessary, refill radiator up to filler neck with coolant.
15. Refill reservoir tank to Max line with coolant.
16. Repeat step 9 through step 15 two or more times.
17. Warm up engine, and check for sound of coolant flow while running engine from idle up to 2,000 rpm with heater tempera-
ture control set at several positions between COOL and HOT.
I Sound may be noticeable at heater water core.
18. If sound is heard, bleed air from cooling system by repeating steps 11 through 17 until coolant level no longer drops.
I Clean excess coolant from engine.
Checking Cooling System
CHECKING HOSES AND CLAMPS
Check hoses and clamps for proper attachment, leaks, cracks,
damage, loose connections, chafing and deterioration.

21. Hook hoists to slingers to secure the position.
22. Remove installation nuts for left and right engine mount insula-tors.
23. While adjusting position frequently, hoist and remove the engine.
CAUTION:
I While performing operation, check that all necessary wires
and pipes are disconnected.
I Avoid interference with parts on the vehicle.
Installation
Install the engine in the reverse order of the removal procedure.
IKeep each mount insulator from oil adherence and damage.
I While keeping each mount insulator free from twisting, tighten
mounting bolts and nuts for the engine mount.
Inspection
IBefore starting the engine, check coolant level and grease
amount, and if necessary, refill them to the specified level.
I Start the engine, and check that there is no abnormal noise or
vibration.
I Warm up the engine to the sufficient temperature, and check
that there is no leakage of coolant, greases, fuel, or exhaust
gas.
