3. DISCONNECTION OF RADIATOR UPPER HOSE
Make mating marks on the radiator hose and the hose
clamp, and then remove the radiator hose.
8. DISCONNECTION OF FUEL HIGH PRESSURE HOSE Relieve pressure in the fuel pipe line to prevent fuel
outflow.
(Refer to GROUP
13-Service Adjustment Procedures.)
Caution
Cover fuel pipe line with rag after relieving pressure as
certain pressure may still remain.
15. REMOVAL OF FUEL RAIL, FUEL INJECTION AND PRESSURE REGULATOR
Remove fuel rail with fuel injector and pressure regulator.
Caution Do not drop injector when removing fuel rail.
INSPECTION
MlSMCAI
Check the following points; replace the part if a problem is
found.
INTAKE MANIFOLD PLENUM
(1) Check intake manifold plenum for defect or cracks. Re- place if defective 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.)

3. CONNECTION OF RADIATOR UPPER HOSE Align the mating marks on the radiator hose and the hoseclamp and install; then apply pressure where shown by
the arrows in the illustration so that the clamp is correctly
seated at the clamp’s previous trace indentations.
Caution Be absolutely sure that the hose clamp is correctly
seated to its previous trace indentations.
