Engine Noise
23.Engine Noise
A: INSPECTION
NOTE*:
When disconnecting fuel injector connector, the malfunction indicator light illuminates and DTC is stored in ECM memory.
Therefore, carry out the clear memory mode
Regular clicking soundSound increases as engine
speed increases. Valve mechanism is defective.
Incorrect valve clearance
Worn valve rocker
Worn camshaft
Broken valve spring
Heavy and dull clankOil pressure is low. Worn crankshaft main bearing
Worn connecting rod bearing (big end)
Oil pressure is normal. Loose flywheel mounting bolts
Damaged engine mounting
High-pitched clank (Spark
knock)Sound is noticeable when
accelerating with an overload. Ignition timing advanced
Accumulation of carbon inside combustion chamber
Wrong spark plug
Improper gasoline
Clank when engine speed is
medium (1,000 to 2,000 rpm).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 warmSound 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 — Defective generator brush and rotor contact
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 — Loss of compression
Air leakage in air intake system, hoses, connections or mani-
folds
Timing belt noise — Loose timing belt
Belt contacting case/adjacent part
Valve tappet noise — Incorrect valve clearance

COOLING
Engine Coolant
B: INSPECTION
1. RELATIONSHIP OF SUBARU COOLANT
CONCENTRATION AND FREEZING TEM-
PERATURE
The concentration and safe operating temperature
of the SUBARU coolant is shown in the diagram.
Measuring the temperature and specific gravity of
the engine coolant will provide this information.
[Example]
If the engine coolant temperature is 25°C (77°F)
and its specific gravity is 1.054, the concentration is
35% (point A), the safe operating temperature is −
14°C (7°F) (point B), and the freezing temperature
is −20°C (−4°F) (point C).
2. PROCEDURE TO ADJUST THE CON-
CENTRATION OF THE ENGINE COOLANT
To adjust the concentration of the engine coolant
according to temperature, find the proper fluid con-
centration in the above diagram and replace the
necessary amount of the engine coolant with an
undiluted solution of SUBARU genuine coolant
(concentration 50%).
The amount of the engine coolant that should be
replaced can be determined using the diagram.
[Example]
Assume that the engine coolant concentration must
be increased from 25% to 40%. Find point A, where
the 25% line of the engine coolant concentration in-
tersects with the 40% curve of the necessary the
engine coolant concentration, and read the scale
on the vertical axis of the graph at height A. The
quantity of coolant to be drained is 2.12 (2.2 US qt,
1.8 Imp qt). Drain 2.12 (2.2 US qt, 1.8 Imp qt) of
the engine coolant from the cooling system and
add 2.12 (2.2 US qt, 1.8 Imp qt) of the undiluted
solution of SUBARU coolant.
If a engine coolant concentration of 50% is needed,
drain all the engine coolant and refill with the undi-
luted solution only.
