Removal and InstallationAJS0015D
REMOVAL
1. Set the temperature at 18°C (60°F), and then disconnect the battery negative cable.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge refrigerant.
3. Remove the mounting bolt, and then remove the low-pressure pipe 2 and high-pressure pipe 3. Refer to
ATC-151, "
Removal and Installation of Low-pressure Pipe 2 and High-pressure Pipe 3" .
CAUTION:
Seal connection opening of piping with a cap or vinyl tape to avoid exposure to atmosphere.
4. Slide the evaporator to passenger side, and then remove the
intake sensor.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:

Replace O-rings for A/C piping with new ones. Before installing, apply compressor oil to them.

Connection point for female-side piping is thin. So, when inserting male-side piping, take care not
to deform female-side piping. Slowly insert in axial direction.

Insert one-touch joint connection point securely until it clicks.

After piping has been connected, pull male-side piping by hand to make sure piping does not
come off.

When recharging refrigerant, check for leaks.

WARNING:
Avoid breathing A/C refrigerant and lubricant vapor or mist. Exposure may irritate eyes, nose and
throat. Remove HFC-134a (R-134a) from A/C system using certified service equipment meeting
requirements of SAE J-2210 [HFC-134a (R-134a) recycling equipment] or J-2201 [HFC-134a (R-134a)
recovery equipment]. If accidental system discharge occurs, ventilate work area before resuming ser-
vice. Additional health and safety information may be obtained from refrigerant and lubricant manu-
facturers.
