Drier Dessicant Bag

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.

The first step before servicing the A/C accumulator requires removal of the air conditioning refrigerant desiccant through refrigerant recovery process. The front bumper facia deflector needs to be removed first. Begin by taking out the bottom plug of the A/C accumulator followed by the filter and the desiccant bag. Begin the installation process by putting the new desiccant bag followed by the filter unit. The bottom plug requires lubrication using refrigerant oil so installation can be completed by tightening it to 12.5 N.m (111 lb in). Finally, place the front bumper facia deflector back onto position then lower the vehicle while applying the correct amount of oil. Evacuation and recharging the refrigerant must follow while using a Halogen Leak Detector (J 39400-A) to perform fitting leak tests.

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.

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.

The first step to change the air conditioning refrigerant desiccant is refrigerant recovery. Start by removing the front air deflector before taking out the A/C accumulator plug where you should note the PAG oil loss to check the total system amount. Proceed to eliminate the A/C accumulator then put in the fresh replacement A/C accumulator. The O-rings should receive lubrication before installing the A/C accumulator plug with a tightness of 2.9 Nm (26 lb in). Return the front air deflector then bring down the vehicle. Introduce the required oil amount before conducting an evacuation then recharge of refrigerant. You should examine the fittings of the component through using J 39400-A to test for leaks.

Refrigerant recovery must precede the procedure of raising and supporting the vehicle before moving forward with A/C Accumulator replacement. Start by extracting the front air deflector retainers together with the front air deflector unit from the vehicle. Before removing the A/C Accumulator, users must detach its plug and note PAG oil displacement to preserve system oil quantity. After positioning the A/C Accumulator correctly, replace it with lubricant on the O-ring of the A/C Accumulator plug. Place the A/C Accumulator plug on and tighten it to 2.9 Nm (26 lb in). Next, reinstall both the front air deflector along with its retainers before you lower the vehicle. The system requires the right amount of oil before the refrigerant evacuation and recharging procedure takes place. A J 39400-A Halogen Leak Detector must be used to perform a leak test on the component fittings.

Tighten it to 12.5 Nm (111 lb in).

Leak test the fittings of the component with the Halogen Leak Detector (J 39400-A).

Install the desiccant bag plug, tightening it to 2.9 Nm (26 lb in).

Remove the front air deflector and the desiccant bag plug.

Begin by recovering the refrigerant.
