31. REMOVE NO. 3 TIMING BELT COVER
Remove the 3 bolts and timing belt cover.
NOTICE:
Support the timing belt, so the meshing of the crank-
shaft timing pulley and timing belt does not shift..
Be careful not to drop anything inside the timing belt
cover
Do not allow the belt to come into contact with oil, wa-
ter or dust.
32. REMOVE CAMSHAFTS
NOTICE:
Since the thrust clearance of the camshaft is small, the
camshaft must be kept level while it is being removed. If the
camshaft is not kept level, the portion of the cylinder head
receiving the shaft thrust may crack or be damaged, caus-
ing the camshaft to seize or break. To avoid this, the follow-
ing steps should be carried out.
(a) Remove the exhaust camshaft.
(1) Set the knock pin of the intake camshaft at 10 − 45°
BTDC of camshaft angle.
HINT:
The above angle allows No. 2 and No. 4 cylinder cam lobes of
the exhaust camshaft to push their valve lifters evenly.
(2) Secure the exhaust camshaft sub gear to drive gear
with a service bolt.
Recommended service bolt:
Thread diameter6 mm
Thread pitch1.0 mm
Bolt length16 − 20 mm (0.63 − 0.79 in.)

24. REMOVE FRONT EXHAUST PIPE
(a) Using a 14 mm deep socket wrench, remove the 2 bolts
holding the front exhaust pipe to the front TWC.
(b) Remove the 2 bolts and 2 nuts holding the front exhaust
pipe to the TWC w/ pipe.
(c) Remove the front exhaust pipe and 2 gaskets.
25. DISCONNECT A/C COMPRESSOR FROM ENGINE
(a) Disconnect the A/C compressor connector.
(b) Remove the 2 bolts, nut and stud bolt, and disconnect the
A/C compressor from the engine.
HINT:

32. REMOVE ENGINE AND TRANSAXLE ASSEMBLY
FROM VEHICLE
(a) Install a engine hange No. 1 in the correct direction.
Part No. 1:
Engine hanger No. 1 12281−74060
Bolt 91611−B1020
Torque: 25 N·m (250 kgf·cm, 18 ft·lbf)
(b) Attach the engine sling device to the engine hangers.
(c) Remove the 2 nuts and 2 bolts, and disconnect the LH en-
gine mounting bracket from the mounting insulator.

FINDING A SHORT CIRCUIT
(a) Remove the blown fuse and disconnect all loads of the
fuse.
(b) Connect a test light in place of the fuse.
(c) Establish conditions in which the test light comes on.
Example:
- Ignition SW on
- Ignition SW and SW 1 on
- Ignition SW, SW 1 and Relay on (Connect the
Relay) and SW 2 off (or Disconnect SW 2)
(d) Disconnect and reconnect the connectors while
watching the test light.
The short lies between the connector where the test
light stays lit and the connector where the light goes
out.
(e) Find the exact location of the short by lightly shaking
the problem wire along the body.
CAUTION:
(a) Do not open the cover or the case of the ECU unless
absolutely necessary. (If the IC terminals are
touched, the IC may be destroyed by static
electricity.)
(b) When replacing the internal mechanism (ECU part)
of the digital meter, be careful that no part of your
body or clothing comes in contact with the
terminals of leads from the IC, etc. of the
replacement part (spare part).
DISCONNECTION OF MALE AND FEMALE
CONNECTORS
To pull apart the connectors, pull on the connector itself, not the
wire harness.
HINT: Check to see what kind of connector you are disconnecting
before pulling apart.
