Caution
•  If a non-specified grease is used, it may result in abnormal noise or an operation malfunction of the links.

1.  Disconnect the negative battery terminal and wait for 1 min or more. (See NEGATIVE BATTERY TERMINAL DISCONNECTION/CONNECTION.)

2.  Collect the refrigerant. (See REFRIGERANT RECOVERY.)

3.  Drain the engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.0].)

4.  Remove the A/C unit short-cord. (See A/C UNIT SHORT-CORD REMOVAL/INSTALLATION.)

5.  Remove the A/C unit. (See A/C UNIT REMOVAL/INSTALLATION.)

6.  Disassemble in the order shown in the figure.

7.  Assemble in the reverse order of disassembly.

8.  Add engine coolant. (See ENGINE COOLANT REPLACEMENT [SKYACTIV-G 2.0].)

9.  Inspect for engine coolant leakage. (See ENGINE COOLANT LEAKAGE INSPECTION [SKYACTIV-G 2.0].)

10.  Charge the refrigerant. (See REFRIGERANT CHARGING.)

11.  Perform the air-conditioning system performance test. (See REFRIGERANT SYSTEM PERFORMANCE TEST.)

Evaporator Temperature Sensor Assembly Note

Caution
•  When the evaporator is reused, slide the evaporator temperature sensor away from the conventional position and assemble. If the evaporator temperature sensor is assembled to the conventional position when reusing the evaporator, it may not be assembled correctly due to fin deformation and the sensor may not function.
Note
•  Newly replace an evaporator in which the evaporator temperature sensor cannot be correctly positioned.

1.  Assemble the evaporator temperature sensor at the position shown in the figure.
