AIR CONDITIONING ENGINE
COOLANT TEMPERATURE
SWITCH
(1) Immerse the air conditioning engine coolant temperature switch in oil and then heat (by using a gas stove flame or
similar method) so as to increase the oil temperature.
(2) Check to be sure that the air conditioning engine coolant temperature switch is switched OFF when the oil tempera-ture reaches the standard value.
Standard value:
112-l 18°C (234-244°F)
Caution
The oil used above should be engine oil and should be
stirred well while being heated; do not heat more than
necessary.

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.
