Evaporator Temperature Sensor Assembly Note

1. Assemble the evaporator temperature sensor as 

shown in the figure.

Sensor Clamp Assembly Note

1. Attach the sensor clamp as shown in the figure.

A/C Case Assembly Note

• Before assembling the A/C case, apply sealant (one-component, non-solvent, non-alcohol type) to the groove 

along the joint where A/C case (1) and A/C case (3) are joined. Make sure to apply sealant completely around 
the whole periphery of the joint, and that there are no gaps.
