8) Charge the system to the specified amount and then close the low-pressure hand valve.

4JJ1-TC (Standard Output)
4JJ1-TC (High Output)
4JK1-TC (High Output)

9) Check for refrigerant leaks by using a HFC-134a leak detector.
• A fully charged system is indicated by the sight glass on
the receiver/drier being free of any bubbles (Refer to
"Reading Sight Glass").
• Check the high and low pressure value of the manifold
gauge. (Refer to “CHECKING REFRIGERANT SYSTEM
W ITH MAINFOLD GAUGE” in SERVICE
INFORMATION.)
Immediately after charging refrigerant, both high and low
pressures are slightly high and to the left of the gauge, but they
settle down to the guide pressure valves as shown below:
• Ambient temperature; 30 ∼35 °C (86 ∼95 °F)
• Guide pressure
High-pressure side;
Approx. 1373 ∼1670 kPa (14 ∼17 kg/cm
2 / 199 ∼242 psi)
Low-pressure side;
Approx. 127 ∼245 kPa (1.3 ∼2.5 kg/cm
2 / 18 ∼36 psi)
10) Close the low pressure hand valve and charge valve of the refrigerant container.
11) Stop the air conditioning and the engine.
12) Disconnect the high and low pressure hoses from the manifold gauge fittings.

is cold. There is a
distinct difference
in temperature
between them. The high pressure

between the high

The sight glass provides accurate diagnosis only under the following conditions.
If the vehicle can be tested under these conditions, check the sight glass appearance and compare to the chart.
* Engine speed Idling
* A/C switch "ON"
* Blower fan operating at highest speed
* Air source selector lever at "RECIRC"
* Temperature control knob at coldest position
* Ambient temperature below 35 °C (95 °F) and humidity below 70% (See NOTE 1)
* High side pressure less than 1470 kPa (15 kg/cm
2 / 213 psi) (See NOTE 2)
NOTE 1
If the vehicle cannot be moved to a testing location that meets these specifications, then the sight glass cannot be
used for diagnosis. You must discharge and recover the refrigerant, then recharge the system with the specified
amount of refrigerant. Then continue checking the system performance.
NOTE 2
If the high side pressure is greater than stated, the sight glass cannot be used for diagnosis. You must discharge
and recover the refrigerant, then recharge the system with the specified amount of refrigerant. Then continue
checking system performance.

Checking and Adjusting for Compressor
Replacement
180 cm3 (5.07 lmp fl oz) of oil is charged in compressor
(service parts). So it is necessary to drain the proper amount
of oil from the new compressor.
1) Perform oil return operation.
2) Discharge refrigerant and remove the compressor.
3) Drain the compressor oil and measure the extracted oil.
4) Check the compressor oil for contamination.
5) Adjust oil level as required.

6) Evacuate, charge and perform oil return operation.
7) Check system operation.
CONTAMINATION OF COMPRESSOR OIL
Unlike engine oil, no cleaning agent is added to the
compressor oil. Even is the compressor runs for a long period
of time (approximately 1 season), the oil never becomes
contaminated as long as there is nothing wrong with the
compressor or its method of use.
Inspect the extracted oil for any of the following
conditions:
• The capacity of the oil has increased.
• The oil has changed color to red.
• Foreign substances, metal powder, etc., are present in the
oil.
If any of these conditions exists, compressor oil is
contaminated. Whenever contaminated compressor oil is
discovered, the receiver/drier must be replaced.

OIL RETURN OPERATION
There is close affinity between the oil and the refrigerant.
During normal operation, part of the oil recirculates with the
refrigerant in the system.
W hen checking the amount of oil in the system, or replacing
any component of the system, the compressor must be run in
advance for oil return operation. The procedure is as follows:
1) Open the all doors and engine hood.
2) Start the engine and A/C switch is "ON" and Set the fan control knob at its highest position.
3) Run the compressor for more than 20 minutes between 800 and 1,000 rpm in order to operate the system.
4) Stop the engine.
REPLACEMENT OF COMPONENT PARTS
W hen replacing system component parts, supply the following
amount of oil to the component parts to be installed.
Component parts to be installed Amount of oil
Evaporator 50 cm3 (1.41 lmp fl oz)
Condenser 30 cm3 (0.84 lmp fl oz)
Receiver/drier 30 cm3 (0.84 lmp fl oz)
Refrigerant line (One piece) 10 cm3 (0.28 lmp fl oz)
Refrigeration oil must be replenished if more than two parts
are removed at the same time. After installing these
components, check compressor oil.

SHEET METAL
This section includes items of front end sheet metal that are attached by bolts, screws or clips and related
accessory components.
Anticorrosion materials have been applied to the interior surfaces of some metal panels to provide rust resistance.
W hen servicing these panels, areas on which this material has been disturbed, should be properly recoated with
service-type anticorrosion material.

POWER-ASSISTED STEERING SYSTEM 3B-9
4. Install all the lines and hoses. Fill the system with
new power steering fluid and bleed the system as
described in Bleeding the Power Steering System.
Operate the engine for about 15 minutes.
Remove the pump return line at the pump inlet and
plug the connection on the pump. W hile refilling the
reservoir, check the draining fluid for contamination.
If foreign matter is still evident, replace all lines,
disassemble and clean or replace the powe
r
steering system components. Do not re-use any
drained power steering fluid.
Steering Wheel Free Play Inspection
RTW 73BSH000901
1. W ith the tires in the straight-ahead position, check the amount of steering wheel play by turning the
wheel in both directions until the tires begin to move.
NOTE: The wheel free play should be checked with the
engine running. Free play: 0 - 30 mm (0 - 1.18 in)
2.
Also check the steering wheel for play and
looseness in the mount by moving it back and forth
and sideways. W hen test driving, check for hard
steering, steering shimmy and tendency to pull to
one side.
Front End Alignment Inspection and
Adjustment
Toe-in Adjustment
Toe-in: Refer to Section 3A FRONT ALIGNMENT
1. To adjust the toe-in angle, loosen the lock nuts (2) on the tie rod (1) and turn the tie rod. Turn both rods
the same amount, to keep the steering wheel
centered .
