3.DISCONNECTION OF THE HIGH PRESSURE FlJFL HOSE /;;
Bleed the residual pressure within the fuel pipe line’& as to~prevent the flow of fuel.
For information concerning the method to be folfowed for
bleeding the residual pressure, refer to
P.14-44.Caution
Cover the hose connection with rags to prevent splash,
of fuel that could be caused by some residual pressure
in the fuel pipe line.
12. REMOVAL OF DELIVERY PIPE/ 15. INJECTOR
Remove the deliver-y pipe (with the injectors attached to it).Caution
Care must be taken, when removing the delivery pipe,
not to drop the injector.
INSPEiZTION
INJECTORS
N14NGAA
(1) Measure resistance between terminals of injector using a
circuit tester.+-%Standard value:
/13-1652 [at
20°C (68”F)] <1.8L Engine, 2.0L DOHC
Engine
(NoniTurbo)>
2-3Q [at 20°C (68”F)] <2.0L DOHC Engine (Turbo)>
(2) If the resistance is out of specification, replace the injector.
SERVICE POINTS OF INSTALLATION
N14SDAEl’17. INSTALLATION OF
GROMMET/lG. 0-RINGI15. IN-
JECTOR
(I) After installation of the grommet and O-ring (in that
sequence) to the injector, apply light oil or petrol to the
O-ring.(2) While turning the injector to.the left and right, install it
to the delivery pipe.
(3) Check to be sure that the injector turns smoothly.
Caution
If it does not turn smoothly, the O-ring may be
~trapped remove the injector and then re-insert it
into the delivery pipe and check once again.

V-BELT TENSION CHECKNlSFliAl
1.Check to be sure that the belt is not damaged and that the
V-belt is correctly attached to the groove of the pulley.
NOTE, If there is abnormal noise or belt slippage, check the belt
tension and check for unusual wear or abrasion, or damage,
of the
pullev contact surface, and for scars or scratches onthe
pulley.2.
Press in V-belt at the illustrated position with about 100 N
(22 Ibs.) and measure deflection.
Standard value: 6-9 mm
1.26.35 in.)
3. If there is a deviation from the standard value range, make
an adjustment of the belt tension by following the procedures
described below.
(1) Loosen bolts A, B and C (for holding the oil pump).
(2) Place a bar or similar object against the body of the oil
pump, and, while manually providing the suitable
amount of tension, adjust the amount of
flexion of the
belt.
(3) Tighten bolts A, B and C (for holding the oil pump).
(4) Check the amount of flexion of the belt; readjust if
necessary.
CautionThe check should be made after turning the engine
one time or more in the regular direction of rotation (tothe
dght).
FLUID LEVEL CHECKNlSFIAI
1.Park the vehicle on a flat, level surface, startthe engine, andthen turn the steering wheel several times to raise the
temperature of the fluid to approximately
50-60°C
(122-140°F).2. With the engine running, turn the wheel all the way to the
left and right several times.3. Check the fluid in the oil reservoir for foaming or milkiness.
Check the difference of the fluid level when the engine is
stopped, and while it is running. If the fluid level changes
considerably, air bleeding should be done.
FLUID REPLACEMENTNlSFJAJ
1.Raise the front wheels on a jack, and then support them with
rigid racks.2. Disconnect the return hose connection.
3.Connect a vinyl hose to the return hose, and drain the oil into
a container.
