13. Remove mounting screws, and then remove evaporator cover.
14. Remove mounting bolt, and then remove low-pressure pipe 2
and high-pressure pipe 2.
CAUTION:
Cap or wrap the joint of the pipe with suitable material such
as vinyl tape to avoid the entry of air.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings of A/C piping with new ones, and then apply compressor oil to it when installing
it.

Female-side piping connection is thin and easy to deform. Slowly insert the male-side piping
straight in axial direction.

Insert piping securely until a click is heard.

After piping connection is completed, pull male-side piping by hand to make sure that connection
does not come loose.

When recharging refrigerant, check for leaks.

INSTALLATION
Install liquid tank, and then install liquid tank bracket on condenser.
CAUTION:

Make sure liquid tank bracket is securely installed at protru-
sion of condenser. (Make sure liquid tank bracket does not
move to a position below center of liquid tank.)

Replace O-rings of A/C piping with new ones, and then
apply compressor oil to it when installing it.

When recharging refrigerant, check for leaks.
Removal and Installation of Refrigerant Pressure SensorBJS000HX
REMOVAL
1. Remove condenser. Refer to ATC-142, "Removal and Installation of Condenser" .
2. Remove refrigerant pressure sensor from condenser.
CAUTION:
When working, be careful not to damage the condenser
fins.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
Apply compressor oil to O-ring of refrigerant pressure sensor when installing it.
Removal and Installation of EvaporatorBJS000HY
REMOVAL
1. Remove low-pressure pipe 2 and high-pressure pipe 2. Refer to ATC-140, "Removal and Installation of
Low-pressure Pipe 2 and High-pressure Pipe 2" .
CAUTION:
Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.
2. Slide evaporator, and then remove it from heater & cooling unit
assembly.
3. Remove intake sensor from evaporator, and then remove evap-
orator.

O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2
(high-pressure pipe 3).

Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sen-
sor can be located in the same position.

When recharging refrigerant, check for leaks.

CHECKING PROCEDURE
To prevent inaccurate or false readings, make sure there is no refrigerant vapor, shop chemicals, or cigarette
smoke in the vicinity of the vehicle. Perform the leak test in calm area (low air/wind movement) so that the
leaking refrigerant is not dispersed.
1. Stop the engine.
2. Connect a suitable A/C manifold gauge set (SST) to the A/C service valves.
3. Check if the A/C refrigerant pressure is at least 345 kPa (3.45 bar, 3.52 kg/cm
2 , 50 psi) above 16°C
(61°F). If less than specification, recover/evacuate and recharge the system with the specified amount of
refrigerant.
NOTE:
At temperatures below 16°C (61°F), leaks may not be detected since the system may not reach 345 kPa
(3.45 bar, 3.52 kg/cm
2 , 50 psi).
4. Perform the leak test from the high-pressure side (compressor discharge a to evaporator inlet g) to the
low-pressure side [evaporator drain hose h to shaft seal l (QR engine) or m (VQ engine)]. Refer to AT C -
133, "Components" . Perform a leak check for the following areas carefully. Clean the component to be
checked and move the leak detected probe completely around the connection/component.
Compressor
Check the fitting of high- and low-pressure flexible hoses, relief valve and shaft seal.
Condenser
Check the fitting of high-pressure flexible hose and pipe, refrigerant pressure sensor.
Liquid tank
Check the fitting of refrigerant connection.
Service valves
Check all around the service valves. Ensure service valve caps are secured on the service valves (to pre-
vent leaks).
NOTE:
After removing A/C manifold gauge set from service valves, wipe any residue from valves to prevent any
false readings by leak detector.
Cooling unit (Evaporator)
With engine OFF, turn blower fan on “High” for at least 15 seconds to dissipate any refrigerant trace in the
cooling unit. Wait a minimum of 10 minutes accumulation time (refer to the manufacturer’s recommended
procedure for actual wait time) before inserting the leak detector probe into the drain hose.
Keep the probe inserted for at least 10 seconds. Use caution not to contaminate the probe tip with water
or dirt that may be in the drain hose.
5. If a leak detector detects a leak, verify at least once by blowing compressed air into area of suspected
leak, then repeat check as outlined above.
6. Do not stop when one leak is found. Continue to check for additional leaks at all system components.
If no leaks are found, perform steps 7 - 10.
7. Start the engine.
8. Set the A/C control as follows;
a. A/C switch: ON
b. Mode door position: VENT (Ventilation)
c. Intake door position: Recirculation
d. Temperature setting: Max. cold
e. Fan speed: High
9. Run engine at 1,500 rpm for at least 2 minutes.
