Installation

To install, follow the removal steps in the reverse order,
noting the following points:

1. The sensor is installed on the core with the clip.
2. The sensor must not interfere with the evaporator

core.

3. When installing the new evaporator core, install the

duct sensor (2) to the evaporator core (1) specified
position with the clip in the illustration.

4. O-rings cannot be reused. Always replace with new

ones.

5. Be sure to apply new compressor oil to the O-rings

when connecting lines.

6. Be sure to install the sensor and the insulator on the

place where they were before.

7. To install a new evaporator core, add 50cc (1.7 fl. oz.)

of new compressor oil to the new core.

8. Tighten the refrigerant lines to the specified torque.

Refer to 

Main Data and Specifications for Torque

Specifications in this section.
