Evaporator Core: Service and Repair

Removal and Installation of Evaporator

REMOVAL
1. Remove low-pressure pipe 2 and high-pressure pipe 2. Refer to "Removal and Installation of Low-Pressure Pipe 2 and High-Pressure Pipe 2".

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.
3. Remove intake sensor from evaporator, and then remove evaporator.

INSTALLATION
Installation is basically the reverse order of removal.

CAUTION:
- Replace O-rings for A/C piping with new ones, then apply compressor oil to it when installing it.
- Connection point for female-side piping is thin. So, when inserting male-side piping, take care not to deform female-side piping. Slowly insert in axial direction.
- Insert one-touch joint connection point securely until it clicks.
- After piping has been connected, pull male-side piping by hand to make sure piping does not come off.
- The O-rings are different from low-pressure pipe 1 (high-pressure pipe 1) and low-pressure pipe 2 (high-pressure pipe 2).
- Mark the mounting position of the intake sensor bracket.
- When recharging refrigerant, check for leaks.
