Q: How to replace the A/C Accumulator desiccant on Cadillac CTS?
A: Recovery of the refrigerant must take place first in order to replace the air conditioning accumulator. The process starts by removing the front bumper facia deflector followed by extracting the A/C accumulator bottom plug then the filter alongside the desiccant bag. Begin the installation process by setting the new desiccant bag followed by the filter installation. It is necessary to apply refrigerant oil to the O-rings found on the plug prior to installation. Secure the bottom plug by torquing it to 12.5 Nm (111 lb in). The front bumper facia deflector should be reinstalled followed by lowering the vehicle down. Apply the right amount of oil and complete the evacuation and recharging process of refrigerant. A Halogen Leak Detector (J 39400-A) should be used to test for leaks on the component fittings.
Q: How to service and repair the A/C Accumulator and replace the air conditioning refrigerant desiccant on Cadillac SRX?
A: Start the repair of the A/C accumulator and its air conditioning refrigerant desiccant by checking the component fittings for leaks with the Halogen Leak Detector (J 39400-A). After refrigerant recovery begins the service procedure by raising the vehicle for support. The service technician must first remove both front air deflector retainers followed by the front air deflector. First remove the desiccant bag plug and note the PAG oil loss in order to keep the appropriate system fluid content during desiccant bag removal. Start desiccant bag installation procedures by inserting the bag then lubricate the O-ring that will secure the desiccant bag plug. Install the desiccant bag plug while tightening it to 2.9 N.m (26 lb in). Lower the vehicle after reinstallation of the front air deflector and its retainers. After installation of the A/C accumulator, add the correct amount of oil then perform an evacuation and recharging of the refrigerant.
Q: How to replace the desiccant bag in the A/C Accumulator on Cadillac STS?
A: The installation process of a new desiccant bag in the A/C accumulator starts with recovering all refrigerant from the system. The installation starts with removing the front air deflector and desiccant bag plug before proceeding with the desiccant bag removal. The measurement of distilled PAG oil loss from the desiccant must be recorded to keep the total system amount accurate. To install the new desiccant bag, start by lubricating the O-rings on its plug before putting it into position. First, install the desiccant bag plug while tightening it to 2.9 N.m (26 lb in). You should reinstall the front air deflector while also lowering the vehicle before filling it with the appropriate amount of oil. Evacuate and recharge the refrigerant then conduct fittings leak inspections with the Halogen Leak Detector (J 39400-A) after finishing the air conditioning unit repairs.
