(NOTE*)
When disconnecting the fuel injector connector, the malfunction indicator light illuminates and DTC is stored in ECM memory.
Therefore, carry out the clear memory mode
mode
Ty p e o f s o u n d C o n d i t i o n P o s s i b l e c a u s e
Regular clicking soundSound increases as engine
speed increases.
•Valve mechanism is defective.
•Incorrect valve clearance
•Worn valve rocker
•Worn camshaft
•Broken valve spring
•Trouble of tappet
Heavy and dull clankOil pressure is low.•Worn camshaft main bearing
•Worn connecting rod bearing (large end)
Oil pressure is normal. Damaged engine mounting
High-pitched clank
Sound is noticeable when
accelerating with an overload
condition.
•Ignition timing advanced
•Accumulation of carbon inside combustion chamber
•Wrong spark plug
•Improper gasoline
Clank when engine speed is
between 1,000 and 2,000
rpms.
Sound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*)
•Worn crankshaft main bearing
•Worn bearing at crankshaft end of connecting rod
Knocking sound when engine
is operating under idling speed
and engine is warm
Sound is reduced when fuel
injector connector of noisy cyl-
inder is disconnected.
(NOTE*)
•Worn cylinder liner and piston ring
•Broken or stuck piston ring
•Worn piston pin and hole at piston end of connecting rod
Sound is not reduced if each
fuel injector connector is dis-
connected in turn. (NOTE*)
•Unusually worn valve lifter
•Worn cam gear
•Worn camshaft journal bore in crankcase
Squeaky sound — • Insufficient generator lubrication
Rubbing sound — • Poor contact of generator brush and rotor
Gear scream when starting
engine—•Defective ignition starter switch
•Worn gear and starter pinion
Sound like polishing glass with
a dry cloth—•Loose drive belt
•Defective water pump shaft
Hissing sound —•Insufficient compression
•Air leakage in air intake system, hose, connection or manifold
Timing belt noise —•Loose timing belt
•Belt contacting with case/adjacent part
Va l ve t a p p e t n o i s e —•Incorrect valve clearance
•Trouble of tappet

Cooling System
PERIODIC MAINTENANCE SERVICES
9. Cooling System
A: INSPECTION
1) To check the radiator for leakage, fill it with en-
gine coolant, and attach the radiator cap tester (A)
to the filler neck, and apply pressure. Check the fol-
lowing points:
157 kPa (1.6 kg/cm2, 23 psi)
NOTE:
•Hose joints and other connections for leakage
•Each portion of radiator for leakage
•Be particularly careful not to deform the filler
neck of radiator when installing and removing the
tester and after testing.
•When performing this check, be sure to keep the
engine stationary and fill radiator with coolant.
•Wipe off check points before applying pressure.
•Use care not to spill coolant when detaching
tester from radiator.
2) Check the radiator cap valve open pressure us-
ing radiator cap tester.
NOTE:
Rust or dirt on the cap may prevent valve from func-
tioning normally:be sure to clean the cap before
testing.
Raise the pressure until the needle of gauge stops
and see if the pressure can be retained for five to
six seconds. The radiator cap is normal if a pres-
sure above the service limit value has been main-
tained for this period.
Radiator cap valve open pressure
Standard:
93 — 123 kPa (0.95 — 1.25 kg/cm2, 14 — 18
psi)
Service limit:
83 kPa (0.85 kg/cm2, 12 psi)
3) Start the engine, and then check it does not
overheat or it is cooled excessively. If it overheats
or it is cooled excessively, check the cooling sys-
tem.
4) Check the radiator fan operates using Subaru
Select Monitor, when the coolant temperature ex-
ceeds 95°C (203°F). If it does not operate, check
the radiator fan system.
