EVAPORATOR TEMPERATURE SENSOR REPLACEMENT

1. Disconnect the 2P connector (A) from the evaporator temperature sensor (B), then remove the connector

clip (C). Turn the evaporator temperature sensor clockwise to the stop, and carefully pull it out.

2. Install the sensor in the reverse order of removal.

EVAPORATOR TEMPERATURE SENSOR TEST

1. Dip the sensor in ice water, and measure the resistance between its terminals.

2. Then pour warm water on the sensor, and check for a change in resistance.

3. Compare the resistance readings with the specifications shown in the graph; the resistance should be

within the specifications.

EVAPORATOR CORE REPLACEMENT

1. Recover the refrigerant with a recovery/recycling/charging station (see REFRIGERANT

RECOVERY ).

2. Remove the bolt, then disconnect the suction line (A) and the receiver line (B) from the evaporator core.

3. Remove the blower unit (see BLOWER UNIT REMOVAL/INSTALLATION ).

4. Remove the bolt and the ECM/PCM bracket (A). Remove the self-tapping screws and the expansion

valve cover (B).

6. Install the core in the reverse order of removal, and note these items:



If you're installing a new evaporator core, add refrigerant oil (DENSO ND-OIL 8) (see A/C
REFRIGERANT OIL REPLACEMENT ).



Replace the O-rings with new ones at each fitting, and apply a thin coat of refrigerant oil before
installing them. Be sure to use the correct O-rings for HFC-134a (R-134a) to avoid leakage.



Immediately after using the oil, reinstall the cap on the container, and seal it to avoid moisture
absorption.



Do not spill the refrigerant oil on the vehicle; it may damage the paint; if the refrigerant oil contacts
the paint, wash it off immediately.



Make sure that there is no air leakage.



Charge the system (see SYSTEM CHARGING ).

A/C COMPRESSOR REPLACEMENT

1. If the A/C compressor is marginally operable, run the engine at idle speed, and let the air conditioning

work for a few minutes, then shut the engine off.

2. Make sure you have the anti-theft code for the audio system, then write down the audio presets.

3. Disconnect the negative cable from the battery.

4. Recover the refrigerant with a recovery/recycling/charging station (see REFRIGERANT

RECOVERY ).

5. Remove the radiator reservoir tank.

6. Remove the power steering pump (see PUMP REPLACEMENT ).

7. Remove the alternator (see ALTERNATOR REMOVAL AND INSTALLATION ).

8. Remove the front grille cover and bulkhead (see RADIATOR AND FAN REPLACEMENT ).

9. Remove the A/C compressor clutch connector (A) from the A/C condenser fan shroud (B), then open the

wire harness clip. Disconnect the A/C condenser fan connector (C). Remove the upper mounting bolts
and the A/C condenser fan shroud. Be careful not to damage the radiator fins when removing the A/C
