2001 NISSAN PICK-UP sensor

Removal operation
15. Install the engine slingers (standard service part) to front-left
and rear-right.
: 29.5 - 37.3 Nzm (3.0 - 3.8 kg-m, 22 - 27 ft-lb)
WARNING:
For engines without engine slingers, attach proper slingers
and bolts described in the PARTS CATALOG.
16. Hook hoists to slingers to secure the position.
17. Remove installation nuts for left and right engine mount insu-
lators.
18. Remove crankshaft position sensor (TDC sensor) from trans-
mission.
19. Separate engine and transmission, remove the engine.
CAUTION:
+While performing operation, check that all necessary
wires and pipes are disconnected.
+Avoid interference with parts on the vehicle.
Installation
Install the engine in the reverse order of the removal procedure.
+Keep each mount insulator from oil adherence and damage.
+As for a location with positioning pin, insert the pin correctly
to the hole of mating part.
+While keeping each mount insulator free from twisting,
tighten mounting bolts and nuts for the engine mount.
Inspection
+Before starting the engine, check levels of coolant, engine oil,
and other operating fluids, and if necessary, refill them to the
specified level.
+Start the engine, and check that there is no abnormal noise
or vibration.
+Warm up the engine to the sufficient temperature, and check
that there is no leakage of coolant, greases, fuel, or exhaust
gas.

EM-3065

Removal and Installation
CAUTION:
+When installing bearings, pistons, or other sliding parts,
lubricate contacting surfaces with new engine oil.
+Place removed parts such as bearings and bearing caps
in their proper order and direction.
+When installing connecting rod nuts, and main bearing
cap bolts, apply new engine oil to threads and seating
surfaces.
+Do not allow any magnetic materials to contact the sig-
nal plate of flywheel.
+Do not remove the signal plate at back.
+Do not place the signal plate side facing under.
+Handle with care so as not to damage the signal plate
[especially four places on protrusions for signal of crank
position sensor (TDC sensor)].
Disassembly
PISTON AND CRANKSHAFT
1. Remove engine. Refer to ªENGINE REMOVALº, EM-3063.
2. Place engine on a work stand.
a. Remove flywheel.
+Hold ring gear with ring gear stopper (KV10105630,
KV10105610). Then, loosen securing bolts with TORX
socket (size: Q8 E20, Commercial Service Tool) and remove
them. As an alternative method, hold the crankshaft pulley
with a pulley holder (SST) to remove the flywheel.
b. Install engine sub-attachment (SST) to rear surface of cylin-
der block.
+To install, align the hole on the sub-attachment with the
knock pin on the cylinder block.
+The engine sub-attachment has five bolts.
c. Install engine attachment (SST).
+The four sets of bolts and nuts are multi-purpose products.

Checking and Replacing Fuel Filter and
Draining Water
Be careful not to spill fuel in engine compartment. Place a
rag to absorb fuel.
CHECKING FUEL FILTER
Check fuel filter for fuel leakage, damage and other abnormal
signs.
REPLACING FUEL FILTER
1. Disconnect harness connector and drain fuel.
2. Remove two installation bolts. Remove fuel filter and fuel fil-
ter bracket assembly from vehicle-side bracket. (It is not nec-
essary to disconnect fuel hose.)
3. Remove fuel filter using band-type filter wrench.
4. Remove fuel filter and fuel filter sensor.
CAUTION:
Remove fuel filter without spilling fuel. If spilt, wipe off
immediately. Be specially careful not to spill fuel on engine
mount insulator.
5. Wipe clean fuel filter mounting surface on fuel filter bracket
and smear a little fuel on rubber seal of fuel filter.
6. Screw fuel filter on until a slight resistance is felt, then tighten
an additional more than 2/3 of a turn.
7. Install fuel filter sensor to new fuel filter.
8. Bleed air from fuel filter.
Refer to ªAir Bleedingº in EC section.
9. Start engine and check for leaks.
DRAINING WATER
1. Drain water as follows.
Loosen drain cock and drain water by operating priming
pump.
Loosening drain cock four to five turns causes water to
start draining. Do not remove drain cock by loosening it
excessively.
2. Bleed air.
Refer to ªAir Bleedingº in EC section.
