The first repair steps for the A/C Accumulator include discharging refrigerant from the refrigeration system while evacuating air and charging it with 650 plus or minus 50 g (22.92 plus or minus 1.76 oz.) of refrigerant while performing leak checks. Start by taking out the radiator grille while disconnecting the two liquid tubes from the accumulator through bolt uninstallation at 5.4 Nm using a torque wrench. Then secure the open fittings immediately to stop system entry of moisture or dirt. Insert two new O-rings into their tubes while lubricating them with compressor oil then proceed with installation onto the tubes. Plastic accumulators can be extracted after removing the holder bolt then pulling the accumulator downward. The accumulator needs to get 20 cc (0.71 fl.oz.) ND-OIL 8 or an equivalent compressor oil before installation into the unit. The procedure ends with replacing parts in the opposite sequence of removal.

Service and repair work on the A/C Accumulator require first discharging the refrigerant from the refrigeration system following evacuation procedure with final refrigerant charge at 800 plus or minus 50 g (28.22 plus or minus 1.76 oz.) while inspecting for leaks. The service begins by disconnecting the two liquid tubes from the A/C accumulator by removing both tubes and two bolts while using 5.4 N.m torque (55 kgf.cm and 48 in.lbf). The open system fittings must get capped without delay then two new O-rings need lubrication with compressor oil before tube installation. The removal process requires unclipping the holder bolt followed by pulling down the A/C accumulator while adding 20 cc (0.71 fl.oz.) of ND-OIL 8 or similar compressor oil when exchanging the A/C accumulator. The final step involves removing both holder bolts and threaded part from each other. The installation process must follow the exact opposite steps of the removal process.

The first step in repair and service of the A/C Accumulator involves releasing refrigerant from the refrigeration system followed by evacuating air then filling it with 650 plus or minus 50 g (22.92 plus or minus 1.76 oz.) of refrigerant while checking the system for air leaks. Start by opening the radiator grille then disconnect the two liquid tubes from the A/C accumulator while removing its two screws with 5.4 N.m (55 kgf.cm, 48 in.lbf) torque before immediately capping the exposed fittings to stop system contamination. The tubes need two new O-rings to which you should apply compressor oil before mounting them. The A/C accumulator removal process requires germs to remove the holder bolt followed by lowering the A/C accumulator down. The A/C accumulator replacement requires adding 20 cc (0.71 fl.oz.) of ND-OIL 8 or equivalent compressor oil to the compressor system. Take off the bolt while extracting the holder. The installation sequence starts with the opposite steps used for removal.

A proper A/C Accumulator repair method entails first removing refrigerant from the refrigeration system followed by evacuation and system charging with 600 plus or minus 50 g (21.16 plus or minus 1.76 oz.) of refrigerant before leak inspection. The liquid tube between A/C accumulator and cooling unit needs to be disconnected through bolt removal while maintaining 6.0 Nm (60 kg.cm, 52 in.lb) torque setting before the open fittings receive caps for protecting against dirt and moisture contamination. Install the tube by lubricating a new O-ring with compressor oil. After loosening the condenser's nut to disconnect the liquid tube and reaching a torque of 14 Nm (140 kg.cm, 10 ft.lb) you need to remove the two bolts to disconnect both tubes at 6.0 Nm (60 kg.cm, 52 in.lb) before capping the open fittings with compressor oil lubrication of three new O-rings. Locate the holder bolt then pull the A/C accumulator upward after removing it from the holder. The process of A/C accumulator replacement requires a 20 cc (0.71 fl.oz.) addition of ND-OIL 8 or equivalent compressor oil. The final procedure consists of reversing the steps used during removal.

The service and repair process of an A/C accumulator requires refrigerant discharge from its refrigeration system first. The 2 liquid tubes which connect to the A/C accumulator should be disconnected by removing their 2 bolts combined with both tubes and promptly applying caps to exposed fittings to stop system moisture or dirt entry. First remove the A/C accumulator using the procedure of removing its holder and A/C accumulator and then disassembling the bolt from the A/C accumulator. To attach the A/C accumulator to its holder you should use a bolt while adding 20 cc (0.71 fl. oz.) ND-OIL 8 or an equivalent compressor oil if you replace the A/C accumulator. Two bolts should be used to secure the A/C accumulator onto the condenser. Before uniting the liquid tubes, apply ND-OIL 8 or equivalent compressor oil onto 2 new O-rings and install them properly before torquing the connecting 2 bolts to 5.4 Nm (55 kg.cm, 48 in.lb). After evacuating the refrigeration system of all the air follow the charging procedure with the specified 800 plus or minus 50 g (28.22 plus or minus 1.76 oz.) refrigerant amount. The evaluation for refrigerant leakage needs a gas leak detector followed by a joint torque check in the event of detected leakage.

Remove the radiator upper support seal and disconnect the two liquid tubes from the receiver by removing the two bolts and both tubes, applying a torque of 5.4 Nm (55 kg.cm, 48 in.lb).

Reinstall by reversing the removal procedures.

To remove the receiver, take out the holder bolt and pull the receiver downward.

Discharge the refrigerant from the refrigeration system, ensuring to evacuate air and charge the system with 600 ± 50 g (21.16 ± 1.76 oz.) of refrigerant while inspecting for leaks.

Lubricate two new O-rings with compressor oil before installing them onto the tubes.
