II-60ENGINE -Service Adjustment Procedures
(9) If a cylinder’s compression pressure or pressure differenceis outside the limit, fill a small amount of engine oil through
the spark plug hole and repeat Items (7) and (8) above.
@ If the compression is increased when the oil is filled, the piston
and/or cylinder wall may be worn or
damaged.
@ If the compression is not Increased even though the oil is filled, the valve may be thermally seized, the valve
contact may be improper or pressure may leak at the
gasket. (10)Connect the connector of the crankshaft position sensor.
(1l)lnstall
the spark plug and spark plug cable.
(12)Erase the diagnostic trouble code with the scan tool or re-
connect the battery (-)
cable 10 seconds or more after it
was disconnected.
NOTE
This will erase the memory of the diagnostic trouble code which resulted from disconnection of the crankshaft posi-
tion sensor connector.
MANIFOLD VACUUM INSPECTION MllFNAD
(1) Before inspection and adjustment, put the vehicle into the following state.
l Engine coolant temperature:
85-95°C (185-205°F)
l Lights, motor cooling fan, and accessories: OFF
l Transaxle:
N (Neutral)
l Steering wheel: Neutral
(2) Check that the idling revolution speed is normal.
(3) Remove the PCV hose from the PCV valve and attach a
vacuum gauge.
(4) Check that the negative pressure at the intake manifold
during idle revolution is normal.
Standard value: Approx. 500 mmHg
(20 in.Hg)
(5) If outside the standard value, isolate the cause by referring to the following table and repair the fault.

BELT
Caution
1. Before checking, turn the engine one time or more.
2.If the belt tension is too strong, it is possible that the
generator or water pump bearing is damaged. If the belt tension is too weak, however, sounds of its slip-
ping will be heard, and the belt’s service life will be
reduced.
1.Loosen the generator pivot nut
2. Loosen the lock bolt of the belt tension adjuster.
3. Using the adjustment bolt, adjust the belt tension to
specified.
4. Tighten the lock bolt.
5.Tighten the generator pivot nut.
6.Check the deflection or the tension of the belt; readjust if
necessary.
NOTE
Even for a new belt, the adjustment value for a used belt
should be used to make the adjustment if the belt has been used for as long as five minutes or more.
DEFLECTION ADJUSTMENT OF POWER STEERING OIL
PUMP DRIVE BELT 1. Loosen power steering oil pump fixing bolt.
2. Move power steering pump, tension belt moderately and adjust deflection.
3. Tighten fixing bolts.
4. Run the engine one time or more. 5. Check the belt deflection. Readjust, if necessary.

32. DISCONNECTION OF POWER STEERING OIL PUMP Disconnect the oil pump with hoses from the bracket.
NOTE
The removed power steering oil pump should be fastened(by using rope, etc.) in a position that will not interfere
with the removal/installation of the engine assembly.
33. DISCONNECTION OF AIR CONDITIONING COMPRESSOR
Disconnect air conditioning compressor connector and re-
move it with hoses from the compressor bracket.
NOTE
The removed air conditioning compressor should be fas-
tened (by using rope, etc.) in a position that will not inter-
fere with the removal/installation of the engine assembly. OlA0177
37. DISCONNECTION OF ENGINE MOUNT BRACKETBefore removing the engine mount bracket installation
bolt, use a chain block or similar arrangement to suspend
the engine assembly (to the extent that there is no
looseness of the chain).
39. REMOVAL OF ENGINE ASSEMBLY After checking that the cables, hoses, harness connec-
tors, etc. are all removed, slowly raise the chain block tolift the engine assembly upward out of the engine
compartment.
