• Q: How to replace the A/C Expansion Valve in an A/C system on 2004 Cadillac SRX?

  A: After obtaining the refrigerant from the a/c system you can begin replacing the A/C Expansion Valve (TXV). The removal process begins with taking away both the i/p retainer and insulation material from the A/C Expansion Valve. Begin the procedure by first removing the hvac line clamp screw before taking away the hvac line clamp. Then unfasten the A/C Expansion Valve to Evaporator bolts followed by the A/C Expansion Valve line bracket. First disconnect and then carefully straighten out the A/C Expansion Valve from the Evaporator core before removing it from the a/c lines while disposing of all the o-rings. Start with o-ring application before attaching the a/c lines to the A/C Expansion Valve unit during installation tasks. Fix the A/C Expansion Valve onto the Evaporator core by using an A/C Expansion Valve line bracket for installation security. Begin by installing the hvac line clamp followed by securing the A/C Expansion Valve to Evaporator bolts at 3.5 n.m (31 lb in) while tightening the screw of the clamp to 1 n.m (9 lb in). The installation process ends with positioning insulation on lines and A/C Expansion Valve followed by the installation of the i/p retainer and evacuation of the system and conclusion of a leak test through the fittings by using the halogen leak detector (J 39400-A).
