2001 Cadillac DeVille A/C Orifice Tube Parts and Q&A

• Q: How to replace the A/C Orifice Tube in an A/C system on 2001 Cadillac DeVille?

  A: The first step for replacing an A/C Orifice Tube consists of removing refrigerant from the system. Recover the refrigerant from the system before loosening the 0-ring joint with the j 39500-b. Then remove the A/C Orifice Tube from the a/c tube by separating the tubing halves. Use 525 refrigerant to lubricate a new 0-ring before placing the A/C Orifice Tube inside the a/c line before it binds into the 0-ring joint. Use the j 39500-b to tighten the dual 0-ring joint until it reaches 24 n.m (18 lb ft) torque level. Then reposition the line into the plastic hold-down clamp. The objective entails refrigerant recharge of the system followed by leak testing of repaired or reinstalled component fittings through the combination of j 39400 electronic halogen leak detector and j 38042 dual 0-ring tube separator.
