17. REMOVAL OF RADIATOR UPPER HOSEF-isMake mating marks on the radiator hose and hose clamp,
and then disconnect the radiator hose.
25. DISCONNECTION OF HIGH PRESSURE FUEL HOSE
Caution
Cover the hose connection with rags to prevent splash
of fuel that could be caused by some residual ljressure
in the fuel pipe line.For information concerning the bleeding of the residual
pressure, refer to GROUP 14-Service Adjustment Proce-
dures.
39. REMOVAL OF TIMING BELTRefer to
P.9-98.
47. REMOVAL OF CYLINDER HEAD ASSEMBLYUsing the special tool, loosen the bolts in the order shown
in the figure (in 2 or 3 cycles) and remove. Then remove thecylinder head assembly.A

39. INSTALLATION AND ADJUSTMENT OF TIMING BELTRefer to
P.9-104.
25. CONNECTION OF FUEL HIGH PRESSURE HOSEWhen connecting the fuel high-pressure hose to the
delivery pipe, apply a coating of gasoline to the hose union,and insert so that the O-ring is not damaged.
17. INSTALLATION OF RADIATOR UPPER HOSEAlign the mating marks (of the radiator hose and hose
clamp), and then, while applying force in the direction of thearrow in the illustration, set the hose clamp to the trace
marks (on the hose) remaining from the prior connection.
Caution
Be sure to install the hose clamp at the trace marks (on
the hose) remaining from the prior connection.

04A0088 19. DISCONNECTION OF FUEL HIGH PRESSURE HOSE
Relieve pressure in the fuel pipe line to prevent fueloutflow.
(Refer to GROUP 14 - Service Adjustment Procedures.)
Caution
Cover fuel pipe line with rag after relieving pressure ascertain pressure may still remain.16.REMOVAL OF DELIVERY PIPE, FUEL INJECTOR AND
PRESSURE REGULATOR
Remove delivery pipe with fuel injector and pressure
regulator.
CautionDo not drop injector when removing delivery pipe.
INSPECTIONNllMCAl
Check the following points; replace the part if a problem isfound.
AIR INTAKE PLENUM
(1) Check air intake plenum for defect or cracks. Replace ifdefective
or cracked.
(2) Check load (negative pressure) of drain port. Check
cooling water and jet air passages for clogging. Clean if
required.
(3) Check deflection of installation surface with straight edge
and feeler gauge.Standard value: 0.15 mm
(.006 in.) or less
Limit:0.3 mm (.012 in.)05AOOB4

Caution
Be careful not to drop the injector when the delivery
pipe is installed.

mating marks on the radiator hose and the hose
clamp and install; then apply pressure where shown bythe
arrows in the illustration so that the clamp is correctly
seated at the clamp’s previous trace indentations.A
Caution
-Be absolutely sure that the hose clamp is correctly
seated to its previous trace indentations.
