How to replace the A/C Hose liquid line (LHD) on 2004 Cadillac CTS?

Start by recovering the refrigerant as well as removing the air cleaner from the vehicle before liquid line (LHD) replacement. Remove the retaining clip screw from the a/c line while keeping the instrument body parallel to the line. Unplug the electrical connector of the a/c high pressure switch beforehand. You must use the a/c quick joint tool (J 45689) for disconnecting the quick joint by inserting the probe end into the two narrow openings. Use the same tool to disconnect liquid line connections at two points first from strut tower retaining clip and then at the evaporator fitting. Install new o-rings which receive refrigerant oil before inserting the liquid line into the strut tower bracket. Fasten the liquid line to the evaporator while you install the a/c quick connect clamp that requires pressure to get the connection to work properly. The liquid line should undergo a gentle pull test to verify clamp security before coupling it into the condenser while tightening the retaining clip screw to 9.8 n.m (87 lb in). Reinstall the a/c quick connect clamp while checking whether it has properly engaged. After installing the air cleaner assembly the high pressure switch electrical connector should be connected to the switch followed by system evacuation and recharging. Test all fittings in the repaired component or installation system through use of the halogen leak detector model j 39400.

2004 Cadillac CTS Parts Questions & Experts Answers

Q: How to replace the A/C Hose liquid line (LHD) on 2004 Cadillac CTS?
A: Start by recovering the refrigerant as well as removing the air cleaner from the vehicle before liquid line (LHD) replacement. Remove the retaining clip screw from the a/c line while keeping the instrument body parallel to the line. Unplug the electrical connector of the a/c high pressure switch beforehand. You must use the a/c quick joint tool (J 45689) for disconnecting the quick joint by inserting the probe end into the two narrow openings. Use the same tool to disconnect liquid line connections at two points first from strut tower retaining clip and then at the evaporator fitting. Install new o-rings which receive refrigerant oil before inserting the liquid line into the strut tower bracket. Fasten the liquid line to the evaporator while you install the a/c quick connect clamp that requires pressure to get the connection to work properly. The liquid line should undergo a gentle pull test to verify clamp security before coupling it into the condenser while tightening the retaining clip screw to 9.8 n.m (87 lb in). Reinstall the a/c quick connect clamp while checking whether it has properly engaged. After installing the air cleaner assembly the high pressure switch electrical connector should be connected to the switch followed by system evacuation and recharging. Test all fittings in the repaired component or installation system through use of the halogen leak detector model j 39400.
