• Q: How to replace the air conditioning evaporator core on 2010 Cadillac CTS?

  A: Starting the air conditioning Evaporator core replacement requires initial removal of the hvac module assembly. You should first remove the insulation from the thermal expansion valve (TXV) and then unscrew and remove both the hvac line clamp and its clamp screw. The procedure includes removing txv to Evaporator bolts as well as the txv line bracket before pulling the txv straight out from the Evaporator core. The process begins with unscrewing all case-retaining components while disconnecting the thermistor electrical connection and splitting the hvac module apart. After removing the thermistor from the Evaporator core you should remove the Evaporator core itself. The installation process should begin with applying refrigerant oil while also installing new Evaporator core seals before placing the Evaporator core in its correct position. Install the thermistor at its original position before putting the hvac module back together while using the proper screws to secure the case and tightening them to 1 nm torque strength (8 lb in). The installation process begins with adding the case-clips which simultaneously allows you to connect the thermistor electrical connector. Apply refrigerant oil to the a/c lines before inserting them into the txv before carefully placing the txv onto the Evaporator core until correct placement occurs. Align and install the txv line bracket followed by attaching the txv to Evaporator bolts while tightening them to 3.5 nm (31 lb in). Attach the hvac line clamp followed by its screw and tighten to 1 nm (8 lb in). Afterward, position the insulation to cover the lines and txv. Finally, reinstall the hvac module.
