Evaporator Core: Service and Repair

Removal and Installation of Evaporator

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

CAUTION: Cap or wrap the joint of evaporator, low-pressure flexible hose and high-pressure pipe 1 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 low-pressure flexible hose, low-pressure pipe 1 and high-pressure pipe 1, 2 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 flexible hose (high-pressure pipe 1) and low-pressure pipe 1 (high-pressure pipe 2).
- 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.
