Evaporator Core: Service and Repair

Removal and Installation of Evaporator

REMOVAL
1. Remove low-pressure pipe 2 and high-pressure pipe 3.

CAUTION: Cap or wrap the joint of the pipe with suitable material such as vinyl tape to avoid the entry of air.




2. Slide evaporator, and then remove it from heater & cooling unit assembly.
3. Remove intake sensor from evaporator, and then remove evaporator.

INSTALLATION
Installation is basically the reverse order of removal.

CAUTION:
- Replace O-rings of A/C piping with new ones, and then apply compressor oil to it when installing it.
- Female-side piping connection is thin and easy to deform. slowly insert the male-side piping straight in axial direction.
- Insert piping securely until a click is heard.
- After piping connection is completed, pull male-side piping by hand to make sure that connection does not come loose.
- O-rings are different from low-pressure pipe 1 (high-pressure pipe 2) and low-pressure pipe 2 (high-pressure pipe 3).
- Mark the mounting position of intake sensor bracket prior to removal so that the reinstalled sensor can be located in the same position.
- When recharging refrigerant, check for leaks.
