2001 NISSAN ALMERA N16 fuel tank removal

Do not attempt to top off the fuel tank after the fuel pump nozzle
shuts off automatically. Continued refueling may cause fuel
overflow, resulting in fuel spray and possibly a fire.
WARNING:
To prevent ECM from storing the diagnostic trouble codes, do
not carelessly disconnect the harness connectors which are
related to the engine control system and TCM (Transmission
Control Module) system. The connectors should be discon-
nected only when working according to the WORK FLOW of
TROUBLE DIAGNOSES in EC and AT sections.
SGI787
PRECAUTIONS FOR MULTIPORT FUEL INJECTION
SYSTEM OR ENGINE CONTROL SYSTEM
NJGI0001S04+Before connecting or disconnecting any harness connector for
the multiport fuel injection system or ECM:
Turn ignition switch to ªOFFº position.
Disconnect negative battery terminal.
Otherwise, there may be damage to ECM.
+Before disconnecting pressurized fuel line from fuel pump to
injectors, be sure to release fuel pressure.
+Be careful not to jar components such as ECM and mass air
flow sensor.
PRECAUTIONS FOR THREE WAY CATALYSTNJGI0001S05If a large amount of unburned fuel flows into the catalyst, the cata-
lyst temperature will be excessively high. To prevent this, follow the
instructions below:
+Use unleaded gasoline only. Leaded gasoline will seriously
damage the three way catalyst.
+When checking for ignition spark or measuring engine
compression, make tests quickly and only when necessary.
+Do not run engine when the fuel tank level is low, otherwise the
engine may misfire, causing damage to the catalyst.
Do not place the vehicle on flammable material. Keep flammable
material off the exhaust pipe and the three way catalyst.

PRECAUTIONS FOR HOSESNJGI0001S06Hose Removal and InstallationNJGI0001S0601+To prevent damage to rubber hose, do not pry off rubber hose
with tapered tool or screwdriver.

CAUTION:
+After removing timing chain, do not turn crankshaft and
camshaft separately, or valves will strike piston heads.
+When installing chain tensioner, oil seats, or other sliding
parts, lubricate contacting surfaces with new engine oil.
+Apply new engine oil to bolt threads and seat surfaces
when installing camshaft sprocket and crankshaft pulley.
+When removing oil pump assembly, remove camshaft
position sensor (PHASE), then remove timing chain from
engine.
+Be careful not to damage sensor edges.

WARNING:
+Position vehicle on a flat and solid surface.
+Place chocks at front and back of rear wheels.
+Do not remove engine until exhaust system has com-
pletely cooled off, otherwise, you may burn yourself
and/or fire may break out in fuel line.
+Before disconnecting fuel hose, release pressure.
Refer to EC-38, ªFuel Pressure Releaseº.
+Be sure to lift engine and transaxle in a safe manner.
+For engines not equipped with engine slingers, attach
proper slingers and bolts described in PARTS CATALOG.
CAUTION:
+When lifting engine, be sure to clear surrounding parts.
Use special care near accelerator wire casing, brake lines
and brake master cylinder.
+When lifting the engine, always use engine slingers in a
safe manner.
+When removing drive shaft, be careful not to damage
grease seal of transaxle.
+Before separating engine and transaxle, remove crank-
shaft position sensor (POS) from the cylinder block
assembly.
+Always be extra careful not to damage edge of crankshaft
position sensor (POS), or signal plate teeth.
Engine cannot be removed separately from transaxle. Remove
engine with transaxle as an assembly.
REMOVALNJEM0022S011. Drain coolant from radiator and cylinder block. Refer to LC-17,
ªChanging Engine Coolantº.
2. Remove coolant reservoir tank and bracket.
3. Drain engine oil.
4. Remove battery and battery tray.
5. Remove air cleaner and air duct.
6. Remove drive belts.
7. Remove alternator and air conditioner compressor from
engine.
8. Remove power steering oil pump from engine and position
aside.

3. Remove front chain case.
+Move power steering fluid reservoir tank from the bracket.
+Loosen fixing bolts in the reverse order of that shown in the
figure and remove them.
+Remove No. 6, 10, and 11 bolts with the rubber washer as
space is limited for pulling them out.
SEM514G
CAUTION:
+While front chain case is removed, cover openings to pre-
vent entry of foreign material into engine.
+Do not remove two mass dampers on the back of cover.
SEM515G
4. Set the No. 1 piston to TDC on its compression stroke.
+Turn crankshaft pulley clockwise so that the alignment mark
(punched mark) on each camshaft sprocket is positioned as
shown in the figure.
+No position indicator is provided on the crankshaft pulley.
+When installing, color coded links on the secondary tim-
ing chain can be used as alignment marks. Marking may
not be necessary for removal; however, make alignment
marks as required because the alignment mark on fuel
injection pump sprocket may not be easy to see.
JEM124G
5. Remove chain tensioner.
a. Push the plunger of chain tensioner and keep it pressed with
a push pin.
JEM125G
b. Using a hexagon-head wrench (face to face: 5 mm, SST),
remove bolts to remove chain tensioner.

2. Disconnect the fuel hoses from the fuel injection pump.
3. Disconnect the harness connector from the fuel injection
pump.
+Disconnect the connector by pulling the connector stopper
fully.
+When the stopper is fully pulled, the connector will be discon-
nected together. For installation, push the connector half way
first, then press the stopper until it locks, so that the connec-
tor is connected together.
4. Remove the fuel injection pump rear bracket.
JEF352Y
5. Remove the front chain case.
+Move the power steering fluid reservoir tank from the bracket.
+Loosen and remove the mounting bolts in the reverse order of
the numbers shown in the figure.
+As for bolts 6, 10, and 11, remove with rubber washer because
there is not enough space for removing only the bolts.
CAUTION:
To prevent foreign objects from getting in the engine, cover
the opening during the removal of the front chain case.
JEF353Y
6. Adjust the No. 1 cylinder to the top dead center position.
+Turn the crankshaft pulley clockwise, then align the alignment
mark (punched mark) of the camshaft sprocket to the position
shown in the figure.
+There is no indicator on the crankshaft pulley.
+It is not necessary to mark the secondary timing chain for
removal because it can be matched by the link color for instal-
lation. However, the alignment mark on the fuel injection pump
sprocket is difficult to see; mark it if necessary.
JEF354Y
7. Remove the chain tensioner.
a. Push the plunger of the chain tensioner, then fix it with a tool
such as a push pin.
JEF355Y
b. Using the hexagon wrench (face to face: 5 mm) (SST), remove
the mounting bolts, then remove the chain tensioner.
+A multi-purpose tool may also be used.

CAUTION:
Tighten high-pressure rubber hose clamp so that clamp end is
3 mm (0.12 in) from hose end.
Tightening torque specifications are the same for all rubber
hose clamps.
Ensure that screw does not contact adjacent parts.
