Expansion Valve: Service and Repair
Removal and Installation of Expansion Valve
REMOVAL
1. Set the temperature at 18 °C (60 °F), and then disconnect the battery negative cable.
2. Use a refrigerant collecting equipment (for HFC-134a) to discharge the refrigerant.
3. Remove cowl top cover.
4. Remove evaporator.
5. Remove mounting bolts for expansion valve, then remove expansion valve.
INSTALLATION
Installation is basically the reverse order of removal.
CAUTION:
-
Replace O-rings with new ones, then apply compressor oil to them when installing them.
-
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).
-
When recharging refrigerant, check for leaks.
