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 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, and 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.
-
O-rings are different from low-pressure flexible house (high-pressure pipe 1) and low-pressure pipe 1 (high-pressure pipe 2).
-
Mark the mounting position of the intake sensor bracket.
-
When recharging refrigerant, check for leaks.
