- Expansion tube is located in refrigerant line between condenser outlet and evaporator inlet. Disconnect negative battery cable. Remove air cleaner and duct assembly. Discharge A/C system, using approved refrigerant recovery/recycling equipment.
- Disconnect ABS modulator electrical connector. Disconnect A/C pressure sensor electrical connector. Separate liquid line fitting at expansion tube. Remove and discard O-rings. Remove expansion tube from liquid line using needle-nose pliers using a turning and push/pull motion.
