2. Remove 3 bolts of the flexibility plate (engine side)
3. Remove starter and 2 cooling hoses.
4. Disconnect neutral switch connector and odometer sensor.
5. Loosen the drain screw under the housing to bleed ATF and tighten the drain screw with sealing glue when
assembling. Tightening torque is 29~35N.m
6. Loosen the locking bolt for select lever cable.
7. Remove Drive Shaft LH&RH, using plastic stopper in the oil sealing of differential.
8. Detach suspension bolts.
9. Separate transmission from engine after bolts between engine and transmission remove.II. Automatic Transmission Installation1. Check whether torque converter of the transmission is in the right position, the methods as follows:
Check whether the distance from 3 anchor point of torque converter to front contact face of the transmission
box A 28mm , If the space A<28 mm, try install again. The way to install is that left hand catch hold of the
central anchor column of the converter and make it in alignment with input shaft as near as possible, push the torque
converter in rotating way by right hand until it gets to the bottom to meet the requirement of A 28 mm. (See
figure 7-1 and 2)
2. Install Flexibility plate and central plate on the crankshaft end face with 6 bolts in the direction of Figure 2.
Tightening torque is 45~55 N.m. Turn the longer hole of the Flexibility plate to the lowest of the engine position
in order to connect torque converter.Section 2 Hydraulic Torque Converter and TransaxleAutomatic Transaxle Assembly Hydraulic Torque Converter and Transaxle3-30 -

Figure 7-23. Install transmission in the engine, its way like manual transmission. The torque converter cannot be allowed to
move in axial motion during operating (The dimension of A keeps constant). Install starter in the transmission
housing.
4. Connect Flexibility plate with torque converter, using 3 special bolts. The way is as follows. First, assemble one
bolt in the torque converter by the longer hole of the Flexibility plate, and then rotate engine belt pulley to install
the other bolts, finally use torque spanner to tighten the bolts. Tightening torque is 40~50N.m.
5. Install suspension bolt and drive shaft LH&RH, the assembling way like manual transmission.
6. Connect two cooling pipes as showed in the figure 7-3 with the corresponding pipe of transmission with clip.
7. Connect the cable between bracket of throttle and transmission actuator.
8. Throttle valve cable adjustment as follows:
First, use pliers to clip the hexangular position under throttle valve cable.Turn 60°~90°counterclockwise,
and lift throttle valve cable to make throttle valve cable adjustable move to top position, and then turn back
60°~90° clockwise, meanwhile, make it lock (See figure 7-4). Finally put accelerator pedal to end position.
When throttle valve makes "ka-ka" sound, the distance under the throttle valve should meet B=2~8mm. If not,
try again until the gap B=2~8mm under the throttle valve (see figure 7-5), if gap B=2-8mm, throttle valve cable
adjustment is finished.Central

compressor, condenser and evaporator etc, it adsorbs heat in the air through circulation of refrigerant, so as to
reduce air temperature in car body and eliminate water vapour in air, to achieve the purpose of temperature drop
and dehumidification. Heating system mainly consists of heat exchanger and heater unit. It utilizes heat of engine
cooling water to heat air via heat exchanger, so as to achieve the purpose of heating. Regulation and control of
temperature, humidity and flow rate of air in car body is realized via heating and refrigeration systems separately
or jointly.
For parameters of refrigerating system, see the table:

4. Knocking sensor
(1) Knocking sensor is a vibration acceleration sensor. Mounted on engine cylinder body. Sensing element of
the sensor is a piezocrystal. Vibration of engine cylinder body is transferred to piezocrystal via mass block in the
sensor. Since pressure generated by vibration of mass block is applied to piezocrystal, it generates voltage on two
polar planes and turns vibration signal into voltage signal for output.5-122Symptom
Poor accelerationPossible cause
Various liquids, such as engine oil, cooling fluid, brake fluid, water etc
contact the sensor for a long time, which cause corrosion to the sensor. Mounting torque: 20 ± 5 N.M
Repair precautions: sensor must be fitted closely to cylinder body with its metal surface, any type of washer
is not permitted for installation. For wiring of sensor signal cables, note that do not let resonance occur to signal
cables, otherwise they might be broken. Energizing of high voltage between sensor 1 # and 2 # pins must be
avoided, otherwise piezoelectric element might be damaged.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect two meter pens with sensor 1 #, 2 # pin
respectively, its resistance value at room temperature should exceed 1M ohm. Turn digital multimeter to millivolt
position, use a hand hammer to tap near knocking sensor, now voltage signal output should be available.
5. Oxygen sensor
(1) Its sensing element is a ceramic tube, outside is open to exhaust, inside is open to atmosphere. When
temperature of sensing ceramic tube reaches 350°C, it will have the characteristic of solid state electrolyte. Just
utilizing this characteristic, it converts concentration difference of oxygen into electric potential difference, thus
forms electrical signal output. If mixed gas is a bit concentrated, inside and outside oxyanion concentration
difference of ceramic tube is high, electric potential difference is a bit high.
A large number of oxyanions move from inside to outside, output voltage is high (approximate 900mV); if
mixed gas is a bit thin, inside and outside oxyanion concentration difference of ceramic tube is low, electric
potential difference is low, only a small quantity of oxyanions move from inside to outside, output voltage is low
(approximate 100mV).
Possible cause
1. humid water vapor ingresses inside of sensor, temperature
changes rapidly, probe is broken.
2. oxygen sensor "is poisoned". (Pb, S, Br, Si) Symptom
Poor idle speed, poor speedup, tail gas
overproof, too high oil consumption1 2 3 4Oxygen sensor Mounting torque: 40-60 N.m
Repair precautions: it is prohibited to use cleaning fluid, oily liquid or volatile solid on oxygen sensor during
repair.
(2) Simple measuring method:
(Remove joint) turn digital multimeter to ohm position, connect
two meter pens with sensor 1# (white), 2# (white) pin respectively, its
resistance value at room temperature is 1- 6 ohm.
(Connect joint) in idle speed condition, when oxygen sensor
reaches its working temperature of 350°C, turn digital multimeter to
DC voltage position, connect two meter pens with sensor 3# (grey),Engine EFI System-Engine EFI System

Fig. 5-29 Thermal Contraction Method For those parts that are not sure whether they will contract or not, the thermal contraction method shall not
be used to avoiding any side effect. Especially for those thin plates, great attention shall be made to prevent them
from melting down or burning through.
(c) Welding ring
The welding ring method is used to repair the most seriously damaged part of the concave on the plate work
surface. Some rings are welded to connect the rods. (Shown as Fig. 11-30) When the area of the concave is large,
several rings can be welded in a parallel manner, and gets through the rod to make the pulling force act on the plate
surface evenly. The ring can be replaced by the washer. The rod pulls the washer or shaft through a coupling device.
After the concaved plate is flattened by the inertia hammer puller, remove the ring or washer and finish the welding
points.Fig. 5-30 Welding Washer StretchingBody Repair -Repair After Body Damage7-20Washer WasherHeating
