A: INSPECTION
1) Check the radiator for leakage, filling it with cool-
ant and attach the radiator cap tester (A) to filler
neck.
PRESSURE:
157 kPa (1.6 kg/cm
2
, 23 psi)
Check the following points.
• Each portion of radiator for leakage
• Hose joints and other connections for leakage
CAUTION:
• For turbo model, be sure to install tester to
filler tank side.
• When attaching or detaching tester and when
operating tester, use special care not to deform
radiator filler neck.
• When performing this check, be sure to keep
the engine stationary and fill the radiator with
coolant.
• Wipe off check points before applying pres-
sure.
• Use care not to spill coolant when detaching
the tester from radiator.
• Non-turbo model
• Turbo model
2) Check the radiator cap valve open pressure us-
ing radiator cap tester.
Raise the pressure until the needle of gauge stops
and see if the pressure can be retained for 5 to 6
seconds. The radiator cap is normal if a pressure
above the service limit value has been maintained
for this period.
CAUTION:
Rust or dirt on the cap may prevent the valve
from functioning normally: be sure to clean the
cap before testing.
Radiator cap valve open pressure
Standard value:
93 — 123 kPa (0.95 — 1.25 kg/cm
2
, 14 — 18
psi)
Service limit:
83 kPa (0.85 kg/cm
2
, 12 psi)
3) Start the engine, and then check if it does not
over heat or it is cooled excessively. If it overheats
or it is cooled excessively, check the cooling sys-
tem. <Ref. to CO(H4SO)-19, Water Pump.> <Ref.
to CO(H4SO)-24, Thermostat.> <Ref. to
CO(H4SO)-26, Radiator.> <Ref. to CO(H4SO)-32,
Radiator Cap.>
4) Check the radiator fan operates using SUBARU
Select Monitor, when the coolant temperature ex-
ceeds 95
°
C (203
°
F). If not operate, check the radi-
ator fan system. <Ref. to CO(H4SO)-11, Radiator
Fan System.>
