The first step before replacing the A/C Accumulator involves appropriate methods for collecting the refrigerant. The removal of the grille requires extra caution because disconnecting the hoses or lines should not occur until the system fully empties its r134a fluid to prevent injuries. First detach the condenser hose bolt and its attachment to the A/C Accumulator then remove the evaporator tube bolt while dislodging its tube. The condenser hose and evaporator tube assembly should receive caps which stop both moisture entry and oil spillage. Start by removing both bolts from the A/C Accumulator assembly bracket and then separate the A/C Accumulator unit by unwinding the clamp bolt. When adding a new A/C Accumulator to the system users should carefully determine the required pag oil amount. Install the A/C Accumulator bottle into the clamp without tightening while adding new o-rings that require pag oil for internal circulation and 525 viscosity mineral oil on fittings to avoid compressor breakdown. Fasten the bracket bolts of the A/C Accumulator and tighten the A/C Accumulator clamp bolt to 5 n.m (44 lb in). Disconnect the condenser hose from the condenser cap while plugging it and install a fresh seal washer. The evaporator tube needs installation onto the A/C Accumulator while using an evaporator tube bolt to reach a torque tightness of 20 n.m (15 lb ft). The condenser hose needs connection to the A/C Accumulator before using a hand tool to start securing the condenser hose bolt to 20 n.m (15 lb ft). The evacuation and recharging process of the a/c system requires a j39400-a halogen leak detector to analyze the component fittings before reinstalling the grille.

First remove the refrigerant from the A/C Accumulator before removing its grille. Before touching any hoses or lines ensure the system is completely discharged to prevent r134a from causing harm to the operator. First detach the condenser hose bolt followed by the condenser hose from the A/C Accumulator then remove the evaporator tube bolt together with its tube. A set of caps should be installed onto both the condenser hose and evaporator tube to stop moisture and oil from leaking out. Approach the A/C Accumulator bracket bolts and assembly to remove them and loosen the clamp bolt which enables A/C Accumulator extraction. When installing a fresh A/C Accumulator select the recommended pag oil quantity from the specifications based on the system capacity. Put the A/C Accumulator bottle inside the clamp yet avoid tightening the bolts and replace every o-ring with pag oil for internal circulation while 525 mineral oil must solely be applied to threads and o-rings. Place the A/C Accumulator bracket bolts while tightening the clamp bolt to reach 5 nm (44 lb in). First detach the condenser hose cap together with its plug before installing a fresh seal washer. Attach the evaporator tube along with its bolt and achieve proper engagement at 20 nm (15 lb ft). Then connect the condenser hose with its bolt before securing it at 20 nm (15 lb ft). The process ends with evacuation of the a/c system while recharging it followed by leak testing with j 39400-a tool before returning the grille.

The A/C Accumulator replacement process begins by evacuating the refrigerant through the usage of the halogen leak detector (J 39400-A). It is necessary to remove the grille but avoid pulling any hoses or lines before the system discharges its r134a completely because of safety reasons for human injuries. Duplicate the process by first removing the condenser hose bolt then the condenser hose from the A/C Accumulator before proceeding with the evaporator tube bolt then the evaporator tube. Cap both the condenser hose and the evaporator tube assemblage to stop moisture from entering and oil leakage. First free the bolts securing the A/C Accumulator bracket followed by the removal of the accumulator assembly and final removal of the accumulator by loosening the clamp bolt. To replace the A/C Accumulator, proper pag oil amount must be added to the system. Install the A/C Accumulator bottle to the clamp but do not tighten it before placing new o-rings. The r-134a a/c system requires pag as its internal circulatory fluid but fitting threads and o-rings need 525 viscosity mineral oil to avoid compressor breakdown. Secure the A/C Accumulator in position through bolts before tightening the accumulator clamp bolt to 5 n.m (44 lb in). Seal washers for the condenser hose and condenser cap should be replaced after plugging and removing the condenser hose to condenser cap assembly. Connect the A/C Accumulator evaporator tube with its bolt installation while tightening it to 20 n.m (15 lb.ft.). Fasten the condenser hose while beginning hand torking on the bolt then tighten it to 20 n.m (15 lb ft). The a/c system needs evacuation and recharging before the halogen leak detector (J 39400-A) checks component fittings that lead to grille reinstallation.

The first step to change the A/C Accumulator requires recovering the refrigerant through correct procedures. Before removing the grille always verify that all hoses and lines remain attached until the system fully discharges r134a to prevent safety risks. Begin by unscrewing and extracting the condenser hose bolt together with the condenser hose from the A/C Accumulator and then disassemble the evaporator tube bolt alongside the evaporator tube. The condenser hose assembly along with the evaporator tube requires installation of specific caps to stop moisture entry while also blocking oil leakage. Next turn all the bolts securing the A/C Accumulator bracket before removing both the A/C Accumulator assembly and its bracket while loosening the A/C Accumulator clamp bolt to extract the accumulator unit. The system requires the addition of pag oil during replacement of the A/C Accumulator. Place the A/C Accumulator bottle into the clamp without tightening it before installing new o-rings that require pag oil for internal circulation and 525 viscosity mineral oil for fitting threads and o-rings. Connect the A/C Accumulator bolts to their bracket and tighten the A/C Accumulator clamp bolt to 5 n.m (44 lb in). You must first disconnect the condenser hose to condenser cap and plug before putting in a fresh seal washer. The evaporator tube should be installed onto the A/C Accumulator where an evaporator tube bolt will secure it with a torque setting of 20 n.m (15 lb ft). Proceed by attaching the condenser hose to the A/C Accumulator then visually tighten the condenser hose bolt to 20 n.m (15 lb ft). Finish the process by evacuating and charging the a/c system while testing component fittings with halogen leak detector (J 39400-A) followed by grille reintegration.

Attach the A/C refrigerant filter to the evaporator tube with the flow arrow pointing towards the evaporator.

Connect the condenser hose to the receiver dehydrator, hand start the bolt, and tighten it to 20 Nm (15 lb ft).
