While filling, if coolant from engine side spills out, be sure to
reconnect the heater hose.
Fill coolant to the level of the radiator cap at a rate of 2(1-3/4
Imp qt)/min or lower.
(Close the air relief plugs in order starting with the location from
where the coolant began spilling out.)
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.
Replace the copper washer of the air bleeding plug.
Air relief plug:
: 6.7 - 7.9 N·m (0.68 - 0.81 kg-m, 59 - 70 in-lb)
Use genuine Nissan anti-freeze coolant or equivalent
mixed with water (distilled or demineralized).

Refer to MA-19, “RECOMMENDED FLUIDS AND LUBRICANTS”.
Engine coolant capacity (With reservoir tank):
8.7(7-5/8 Imp qt)
Reservoir tank capacity:
0.7(5/8 Imp qt)
Pour coolant through coolant filler neck slowly to allow air
in system to escape.
4. Fill radiator and reservoir tank to specified level.
5. Warm up engine to normal operating temperature without
radiator cap installed.
If coolant overflows radiator filler hole, install radiator cap.
6. 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.
7. 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.
8. Refill reservoir tank to MAX level line with coolant.
9. Repeat steps 4 through 7 two or more times with radiator cap
installed until coolant level no longer drops.
10. Check cooling system for leaks with engine running.
11. 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.
12. 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.

Inspection for Spill Tube AirtightnessNJEC0619S01Before the rocker cover is installed, perform the inspection as fol-
lows.
1. Connect the handy vacuum pump to the spill hose.
2. Check that the airtightness is maintained after the negative
pressure shown below is applied.
Standard:
–53.3 to –66.7 kPa (–533 to –667 mbar, –400 to –500
mmHg, –15.75 to –19.69 inHg)

Air Bleeding of Fuel PipingNJEC0619S02After the repair, bleed air in the piping by pumping the priming
pump up and down until it becomes heavy.
JEF348Y
Injection Pressure TestNJEC0619S031. Install injection nozzle assembly to injection nozzle tester and
bleed air from flare nut.
2. Pump the tester handle slowly (one time per second) and
watch the pressure gauge.
3. Read the pressure gauge when the injection pressure just
starts dropping.
Initial injection pressure:
New
21,476 - 22,457 kPa (214.7 - 224.5 bar, 219 - 229
kg/cm
2, 3,114 - 3,256 psi)
Limit
18,275 kPa (182.7 bar, 186 kg/cm
2, 2,650 psi)
The injection nozzle assembly has a 2-stage pressure injection
function. However, the judgement should be made at the first
stage of the valve opening pressure.
Always check initial injection pressure using a new nozzle.

DESCRIPTIONNJEC0623A water draining cock is on the lower side and a priming pump for
bleeding air is on the upper side.
SEF375Y
AIR BLEEDINGNJEC06241. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds. To start the engine more quickly, crank the engine
while pumping the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
When air is bled completely, the pumping of the priming
pump suddenly becomes heavy. Stop the operation at that
time.
If it is difficult to bleed air by the pumping of the priming
pump (the pumping of the priming pump does not become
heavy), disconnect the fuel supply hose between the fuel
filter and the injection pump. Then, perform the operation
described above, and make sure that fuel comes out. (Use
a pan, etc. so as not to spill fuel. Do not let fuel get on
engine and other parts.) After that, connect the hose, then
bleed air again.
Start engine and let it idle for at least one minute after
performing air bleeding.
WATER DRAININGNJEC06251. Remove the fuel filter, filter bracket, protector assembly from
the dash panel as follows.
a. Remove the air cleaner case (upper), air duct assembly, and
vacuum hose for brake booster (between the vacuum pump
and vacuum pipe).
CAUTION:
After the duct is removed, cover the opening with gum tape,
etc. to prevent foreign object from getting into the engine
during the operation.
b. Disconnect the water level warning sensor harness connector.
c. Remove the mounting nuts on the dash panel, then remove the
fuel filter, filter bracket, and protector assembly from the dash
panel.
It is not necessary to disconnect the fuel hose.
2. Using a tool such as a pliers, loosen the water draining cock
at the bottom of the water level warning sensor located under
the fuel filter.

3. Install the fuel filter, filter bracket, and protector assembly tem-
porarily. Then, drain the water by pumping the priming pump
with the filter standing straight.
Extend the drain hose if necessary.
Water amount when the MI lights up:
65 - 100 m(2.3 - 3.5 Imp fl oz)
CAUTION:
When the water is drained, the fuel is also drained. Use a pan,
etc. to avoid fuel adherence to the rubber parts such as the
engine mount insulator.
4. Tighten the water draining cock, then install the fuel filter, filter
bracket, protector assembly in the reverse order of removal.
CAUTION:
Do not over-tighten the water draining cock. This will damage
the cock thread, resulting in water or fuel leak.
5. Bleed air of the fuel filter. Refer to EC-32.
Start engine and let it idle for at least one minute after
performing air bleeding.

Bleeding Fuel FilterNJFE00231. After the repair, bleed air from the piping by pumping the prim-
ing pump up and down until it becomes heavy.
2. To start the engine, rotate the starter for a maximum of 30
seconds.
To start the engine more quickly, crank the engine while pump-
ing the priming pump (requires two workers).
3. If the engine does not start after rotating the starter for a maxi-
mum of 30 seconds, stop it once, and pump the priming pump
again until it becomes heavy.
4. Rotate the starter again until the engine starts running.
5. After the engine starts, let it idle for at least 1 minute to stabi-
lize the behavior.
NOTE:
When air is bled completely, pumping the priming pump sud-
denly becomes heavy.
Stop the operation at that time.
If it is difficult to bleed air by pumping the priming pump (the
priming pump does not become heavy during pumping), dis-
connect the fuel supply hose between the fuel filter and the
injection pump. Then, pump the priming pump up and down,
and make sure that fuel comes out. (Use a pan and be care-
ful not to spill fuel. Keep fuel clear of the engine.) After that,
connect the hose, then bleed air again.
DEF017
Checking Priming PumpNJFE0024Before checking priming pump, make sure that fuel filter is
filled with fuel.
1. Disconnect fuel return hose.
Place a suitable container beneath hose end.
2. Pump priming pump and check that the fuel overflows from the
hose end. If not, replace priming pump.
Removal and InstallationNJFE0015WARNING:
When replacing fuel line parts, be sure to observe the following.
Put a “CAUTION: FLAMMABLE” sign in workshop.
Be sure to furnish workshop with a CO
2fire extinguisher.
Do not smoke while servicing fuel system. Keep open flames and sparks away from work area.
CAUTION:
Before removing fuel line parts, carry out the following procedures:
a) Put drained fuel in an explosion-proof container and put the lid on securely.
b) Disconnect battery ground cable.
