  Q: How to replace the evaporator core in an A/C system on Cadillac Catera?

  A: A proper replacement of the Evaporator core requires an initial recovery of the refrigerant from the entire a/c system. Begin by extracting the txv component together with the Steering Column then the Brake Pedal equipped with its bracket. After plugging the fittings you should slowly pull the Evaporator core from the hvac module while managing to prevent refrigerant oil from dripping on interior trim. The process for installation involves carefully fitting the new Evaporator core inside the hvac module followed by reinstallation of the Brake Pedal with bracket and Steering Column and txv. Finish the process by vacuuming out and recharging the a/c system followed by leakage checks on component fittings through the electronic halogen leak detector (J 39400-A).
