NOTE:
Explained here is how to disassemble with engine stand s
upporting transmission surface. When using a differ-
ent type of engine stand, note the difference in the steps, etc.
1. Remove the engine assembly from the vehicle. Refer to EM-98, "
Exploded View".
2. Remove crankshaft pulley. Refer to EM-96, "
FRONT OIL SEAL : Removal and Installation".
NOTE:
The drive plate is fixed with a ring gear stopper [SST: KV10119200 (J-49277)]. Loosen the crankshaft pul-
ley mounting bolts before installing the engine stand.
3. Remove the parts that may restrict installation of engine to a widely used engine stand.  Fix crankshaft with a ring gear stopper [SST: KV10119200 (J-49277)]. Loosen drive plate mounting bolt
with power tool.
 Check for deformation or damage of drive plate. Refer to EM-115, "
Inspection".
NOTE:
The procedure is described assuming that you us e a widely used engine stand holding the surface, to
which transmission is installed.
4. Remove pilot converter using the pilot bushing puller (commercial service tool), if necessary.
5. Lift the engine with hoist to inst all it onto the widely used engine stand.
CAUTION:
Use an engine stand that has a load capacity [240 kg (529 lb) or more] large enough for supporting
the engine weight.
 If the load capacity of the stand is not adequate, remove the following parts beforehand to reduce the potential risk of overturning the stand.
- Remove intake manifold. Refer to EM-30, "
Exploded View".
- Remove fuel injector and fuel tube assembly. Refer to EM-48, "
Exploded View".
- Remove ignition coil. Refer to EM-29, "
Exploded View".
- Remove rocker cover. Refer to EM-33, "
Exploded View".
- Remove exhaust manifold. Refer to EM-40, "
Exploded View".
- Other removable brackets. NOTE:
The figure shows an example of widely used engine stand (A)
that can hold mating surface of transmission with drive plate
removed.
CAUTION:
Before removing the hang ing chains, check the engine
stand is stable and there is no risk of overturning.
6. Drain engine oil. Refer to LU-8, "
Draining".

HFC-134a (R-134a) Service Tool and Equipment
 Never mix HFC-134a (R-134a) refrigerant and/or its s pecified lubricant with CFC-12 (R-12) refrigerant and/
or its lubricant.
 Separate and non-interchangeable service equipment must be used for handling each type of refrigerant/ lubricant.
 Refrigerant container fittings, service hose fittings and service equipment fittings (equipment which handles
refrigerant and/or lubricant) are different between CF C-12 (R-12) and HFC-134a (R-134a). This is to avoid
mixed use of the refrigerants/lubricant.
 Never use adapters that convert one size fitting to another: refrigerant/lubricant contamination occurs and
compressor malfunction may result.

Rear Blower MotorINFOID:0000000006275858
The rear blower motor utilizes a brush-less motor with a rotating
magnet. Quietness is improved comp aring to a conventional motor
(brush motor) that rotates coil while brush functions as contact
points.
Refrigerant Pressure SensorINFOID:0000000006275859
Description
Refrigerant pressure sensor is installed to upper porti on of liquid tank. The refrigerant pressure sensor con-
verts high-pressure side refrigerant pressure into vo ltage and outputs it to ECM. ECM operates cooling system
protection and idle speed control according to voltage value that is input.
Structure and operation
The refrigerant pressure sensor is a capacitance type sensor. It consists of a pressure detection area and a
signal processing area. The pressure detection area, wh ich is a variable capacity condenser, changes internal
static capacitance according to pressure force. The signal processing area detects the static capacitance of
the pressure detection area, converts the static capacitance into a voltage value, and transmits the voltage
value to ECM.
