damage. Replace the faulty timing belt as needed.
3) Measure the timing belt width W. If it is less than
27 mm (1.06 in), check idlers, tensioner, water
pump pulley and cam sprocket to determine idler
alignment (squareness). Replace the worn timing
belt.
4) Install the front timing belt cover and timing belt
cover (LH).
2. DOHC MODEL
1) Remove the timing belt cover (LH).
2) While cranking the engine at least four rotations,
check the timing belt back surface for cracks or
damage. Replace the faulty timing belt as needed.
3) Measure the timing belt width W. If it is less than
30 mm (1.18 in), check idlers, tensioner, water

General Description
C: CAUTION
Wear working clothing, including a cap, protec-
tive goggles and protective shoes during operation.
Remove contamination including dirt and corro-
sion before removal, installation or disassembly.
Keep the disassembled parts in order and pro-
tect them from dust or dirt.
Before removal, installation or disassembly, be
sure to clarify the failure. Avoid unnecessary re-
moval, installation, disassembly and replacement.
Be careful not to burn yourself, because each
part in the vehicle is hot after running.
Be sure to tighten bolts and nuts to the specified
torque.
Place shop jacks or rigid racks at the specified
points.
Before disconnecting electrical connectors of
sensors or units, be sure to disconnect the ground
cable from battery.
All parts should be thoroughly cleaned, paying
special attention to the engine oil passages, pis-
tons and bearings. Rotating parts and sliding parts such as piston,
bearing and gear should be coated with oil prior to
assembly.
Be careful not to let oil, grease or coolant contact
the timing belt, clutch disc and flywheel.
All removed parts, if to be reused, should be re-
installed in the original positions and directions.
Bolts, nuts and washers should be replaced with
new ones as required.
Even if necessary inspections have been made
in advance, proceed with assembly work while
making rechecks.
Remove or install engine in an area where chain
hoists, lifting devices, etc. are available for ready
use.
Be sure not to damage coated surfaces of body
panels with tools, or not to stain seats and windows
with coolant or oil. Place a cover over fenders, as
required, for protection.
Prior to starting work, prepare the following:
Service tools, clean cloth, containers to catch cool-
ant and oil, wire ropes, chain hoist, transmission
jacks, etc.
Lift-up or lower the vehicle when necessary.
Make sure to support the correct positions.

ENGINE (DIAGNOSTIC)
General Description
The OBD-II diagnostics procedure is different
from the usual diagnosis procedure. When trouble-
shooting the OBD-II models, connect Subaru Se-
lect Monitor or the OBD-II general scan tool to the
vehicle.
2. ENGINE AND EMISSION CONTROL SYS-
TEM
MFI system is a system that supplies the opti-
mum air-fuel mixture to the engine for all the vari-
ous operating conditions through the use of the
latest electronic technology.
With this system fuel, which is pressurized at a con-
stant pressure, is injected into the intake air pas-
sage of the cylinder head. The injection quantity of
fuel is controlled by an intermittent injection system
where the electro-magnetic injection valve (fuel in-
jector) opens only for a short period of time, de-
pending on the quantity of air required for one cycle
of operation. In actual operation, the injection quan-
tity is determined by the duration of an electric sig-
nal applied to the fuel injector and this permits
simple, yet highly precise metering of the fuel.
Further, all the operating conditions of the engine
are converted into electric signals, and this results
in additional features of the system, such as large
improved adaptability, easier addition of compen-
sating element, etc.The MFI system also has the following features:
Reduced emission of harmful exhaust gases.
Reduced in fuel consumption.
Increased engine output.
Superior acceleration and deceleration.
Excellent engine start and warm-up perfor-
mance by the correction of engine coolant tem-
perature and intake air temperature.3. AUTOMATIC TRANSMISSION AND
ELECTRONIC-HYDRAULIC CONTROL SYS-
TEM
The electronic-hydraulic control system consists of
various sensors and switches, TCM and the hy-
draulic controller including solenoid valves. The
system controls the transmission body including
shift control, lock-up control, overrunning clutch
control, line pressure control and shift timing con-
trol. It also controls the AWD transfer clutch. In oth-
er words, the system detects various operating
conditions from various input signals and sends
output signals to shift solenoids 1, 2 and low clutch
timing solenoid and 2-4 brake timing solenoid, line
pressure duty solenoid, lock-up duty solenoid,
transfer duty solenoid and 2-4 brake duty solenoid
(a total of eight solenoids).
