SERVICE POINTS OF REMOVALNO7lBAC311. DISCONNECTION OF POWER STEERING OIL PUMP
Disconnect the oil pump with hoses from the bracket.
NOTEThe removed power steering oil pump should be fastened
(by using rope, etc.) in a position that will not interfere with
the removal/installation of the engine assembly.
27. REMOVAL OF TURBOCHARGER ASSEMBLY
Remove the turbocharger assembly with the exhaust
fitting, water pipe A, water pipe
B and the oil pipe attached
to it.
38. DISCONNECTION OF RADIATOR LOWER HOSE
After making mating marks on the radiator hose and the
hose clamp, disconnect the radiator hose.
INSPECTIONN07lCAAa3WATER PIPE AND HOSE INSPECTION
Check the water pipe and hose for cracks, damage, clog and
replace them if necessary.
SERVICE POINTS OF INSTALLATION
N071DAJ345. INSTALLATION OF
0-RING/44. WATER INLET PIPE
Insert the O-ring to the water inlet pipe, and coat the outer
circumference of the O-ring with water.
By coating with water, the insertion to the water pump will
become easier.
Caution
Care must be taken not to permit engine oil or other
greases to adhere to the O-ring.
38. CONNECTION OF RADIATOR LOWER HOSE
Align the mating marks on the radiator hose and hose
clamp and then connect them; then, applying force in the
direction indicated by the arrow in the illustration, seat the
clamp to the trace marks of the previous connection.
Caution
Be sure to install the hose clamps at the trace marks ofthe previous connection.

MANIFOLD VACUUM INSPECTION(1) Before inspection and adjustment, put the vehicle
in=following state.
l Engine coolant temperature:
85-95°C (185-205°F)
l Lights, electric, cooling fan, and accessories: OFF
lTransaxle: Neutral
(N or P for vehicles with an automa-
tic transaxle)
l Steering wheel: Neutral position
(2) Check that the idling revolution speed is normal.
(3) Remove the PCV hose from the PCV valve and attach a
vacuum gauge.
(4) Check that the negative pressure at the intake manifold
during idle revolution is normal.
Standard value: 510 mmHg (20
in.Hg)(5) If outside the standard value, isolate the cause by referring
to the following table and repair the fault.

9-26ENGINE <1.8L Engine> -Service Adjustment Procedures
TIMING BELT TENSION ADJUSTMENTNOSFGBCThere are two access holes provided in the timing belt front
lower cover. The two access holes can be used to readjust thetension of the timing belt, by following the procedures
described below, without the necessity of removing the timing
belt front lower cover. Note, however, that timing belt “B”,
which drives the right silent shaft, cannot be adjusted unless
the cover is removed.
(1) Turn the steering wheel all the way to the left.
(2) Remove the left side undercover panel.
NOTEThis work is done so that the crankshaft can be turned.
(3) Place a piece of wood against the engine oil pan and jack
(4)
:tmove the engine mounting bracket.
(5) Remove the timging belt front upper cover.
(6) Remove the four spark plugs.
(7) Turn the crankshaft clockwise and check the timing belt
condition.
