The input from the upstream heated oxygen sensor tells the Engine Control Module (ECM) the oxygen content of the
exhaust gas. Based on this input, the ECM fine tunes the air-fuel ratio by adjusting injector pulse width.
Downstream Oxygen Sensor
The downstream heated oxygen sensor signal is used to detect catalytic convertor deterioration. As the convertor
deteriorates, the signal from the downstream sensor begins to match the upstream sensor signal except for a slight
time delay. By comparing the downstream heated oxygen sensor signal to the signal from the upstream sensor, the
ECM calculates catalytic convertor efficiency. This calculation is also used to establish the upstream O2 goal voltage
(switching point).

Assembly
1. Put a standard-sized 1.4 mm adjusting shim from the front bearing driven gear axle into the transfer case hous-ing. Press in the front outer bearing race of the driven gear axle, then the rear outer bearing race, and press the
front bearing of the driven gear axle into the driven gear axle; then put it into the collar and press in the rear
inner bearing race. Attach the locknut, and adjust the tightening torque of the driven gear by adjusting the locknut
until the driven gear axle can be driven with a torque of 1.0-1.5 N·m.
2. Assemble the flange axle. Link the drive gear ring of the transfer case to the flange axle with a mounting bolt, tighten the bolt to 110 N·m.
Install the bearing to the left of the flange axle and the bearing to the left of the right bearing seat.
3. Choose the 2.4 mm standard-sized adjusting shim for the left bearing for the flange axle. Put the adjusting shim for the right bearing for the flange axle, the outer bearing race to the left of the flange axle and the flange axle
into the transfer case.
Measure the distance (A) from the contact surface of the right bearing seat and the transfer case to the right
bearing seat and the left bearing’s right end surface.
Measure the distance (B) from the contact surface of the right bearing seat and the transfer case to the place
where the right and left bearings on the right bearing seat.
4. Calculate the thickness value of the adjusting gasket S = A - B.
5. Select the adjusting gasket: S + (0.05 - 0.10) mm.
6. Assembly of the right bearing seat. Assemble the right bearing to the right bearing seat, install the retainer ring of the right bearing to the right
bearing seat, install the fluid seals to the left and right of the right bearing seat, install the O-ring and link the
right bearing seat to the transfer case housing with the bolt. Tighten the bolt to 35 N·m. The subassembly should
be able to rotate with 3.0-5.0 N·m torque.
7. Adjust the hypoid gear engagement: first, spread red lead powder on the teeth of the driven bevel gear so that there will appear red prints on both working sides of the gear teeth of the driving bevel gear when turning it by
hand. If the gear pattern prints on both engaging sides of the drive gear ring is higher than the center of the gear
height near to the small end and occupy over 60% of the gear tooth width, then the pattern is correct; and the
backlash between various gear teeth should fall between 0.13 mm and 0.18 mm.
A: If the clearance between one lateral side of a tooth and that of the adjacent tooth are not correct, choose
bearing shims to the left and right of the flange axle, repeat procedures 3, 4 and 5 to measure the clearance
between one lateral side of a tooth and that of the adjacent tooth on the hypoid gear until the adjustment is
correct.
B: If the gear pattern print leans to the tooth tip, replace the adjusting shim from the front bearing of the driven
gear to a thicker 1 mm; If the gear pattern print leans to the tooth root, then get the adjusting shim of the front
bearing of driven gear axle needs to be subtracted by 1 mm. Examine the gear pattern print, repeat procedures
3, 4, 5, 6, and 7 until the gear pattern is correct.
8. Assemble the transfer case front shell, and tighten to 35 N·m.
9. Assemble the transfer case small rear housing onto the transfer case, and tighten to 35 N·m.
10. Assemble the input clutch fluid seal, O-ring, retainer ring and the input clutch; install the transfer case onto the transaxle and tighten to 80 N·m.
NOTE: When assembling bearings and fluid seals, it is necessary to apply lubricating grease. The sealing sur-
face of the housing must have sealant applied.

Description
Tires are designed and engineered for each specific vehicle. They provide the best overall performance for normal
operation. The ride and handling characteristics match the vehicle’s requirements. With proper care they will give
excellent reliability, traction, skid resistance, and tread life.
Tire Identification
•Tire type, size, load index and speed rating are encoded in the letters and numbers imprinted on the side wall
of the tire.
Spare Tire
• A full size spare tire and wheel assembly is standard equipment on this vehicle. The original tire should be
repaired or replaced at the first opportunity, then reinstalled.
Operation
Driving habits have more effect on tire life than any other factor. Careful drivers will obtain, in most cases, much
greater mileage than severe use or careless drivers. A few of the driving habits which will shorten the life of any tire
are:
•Rapid acceleration
• Severe application of brakes
• High-speed driving
• Taking turns at excessive speeds
• Striking curbs and other obstacles
• Operating vehicle with over or under inflated tire pressures

3. Open both the suction and discharge valves, then open the charge valve to allow the refrigerant to flow into the system.
4. When the transfer of refrigerant has stopped, close both the suction and discharge valves.
5. If all of the refrigerant charge did not transfer from the dispensing device, open all of the windows in the vehicle and set the heating-A/C system controls so that the A/C compressor is operating and the blower motor is running
at its lowest speed setting. Run the engine at a steady high idle (about 2000 RPM).
6. Open the low-pressure valve to allow the remaining refrigerant to transfer to the refrigerant system.
WARNING!
Take care not to open the discharge (high pressure) valve at this time. Failure to follow this warning could result
in possible personal injury or death.
7. Disconnect the refrigerant recovery/recycling station from the refrigerant system service ports.
8. Reinstall the caps onto the refrigerant system service ports.
Compressor
Description
Vehicles equipped with the 1.6L & 1.8L & 2.0L engine use a SD7V16 clutch-less compressor. The 2.4L equipped
vehicles use a V5 clutch-less compressor. The compressor is a variable displacement compressor. The largest dis-
placement is 161.3 ml/r, displacement range of 5% to 100%.
CAUTION:
DONT run the engine with a vacuum pump in operation or with a vacuum present within the A/C
system. Failure to follow this caution will result in serious A/C compressor damage.
NOTE :
The compressor drive hub and the pulley and bearing assembly cannot be serviced separately from the A/C com-
pressor. In the event of drive hub or pulley and bearing assembly damage or failure, the A/C compressor, drive hub
and pulley and bearing must be replaced as an assembly.
Operation
The A/C compressor is controlled by the Engine Control Module (ECM), depending on engine application. The ECM
calculates compressor displacement required by A/C system load and demand by monitoring vehicle speed, A/C high
side pressure, engine speed, evaporator temperature, accelerator pedal position, ambient temperature and A/C-
Heater request signals. The ECM then sends a pulse width modulated signal to the A/C compressor control solenoid
to increase or decrease refrigerant flow through an orifice located within the compressor housing. The amount of
refrigerant allowed to pass through the orifice in the compressor determines the head pressure which controls the
angle of the swash plate, which in turn, determines the amount of compressor displacement. When there is no
demand for A/C, the swashplate is adjusted to nearly a zero degree angle, which removes compressor torque drag
from the engine.
NOTE :
The A/C compressor cannot be repaired and it must be replaced if found inoperative or damaged. If an internal fail-
ure of the A/C compressor has occurred, the A/C accumulator and the A/C liquid line must also be replaced.
