The recovery of refrigerant should be the first step before servicing the thermostatic expansion valve (TXV). Begin by removing the four cross vehicle beam nuts before taking off the beam while tightening the beam installation to 30 Nm (22 lb-ft). The installation of the new TXV manifold bolt requires a bolt torque of 8 Nm (71 lb-in) while you discard the O-ring seals. Follow by unscrewing the two TXV bolts then re-torque these components to 8 Nm (71 lb-in) during reinstallation. To install the component reverse the removal steps while using fresh seals and apply the correct amount of clean PAG oil to the refrigerant system. The last procedure includes evacuation and leak testing followed by refrigerant charging of the system.

The first step for servicing the A/C expansion valve includes recovering all refrigerant from the system. After releasing the four roll restrictor cross beam bolts, you should tighten them to 55 Nm (41 lb-ft) before reinstalling. After installation of the roll restrictor bracket bolt, you should tighten it to 48 Nm (35 lb-ft). The installation of the A/C expansion valve manifold bolt requires discarding O-ring seals before tightening it to 8 Nm (71 lb-in). The two A/C expansion valve bolts need removal before getting tightened to 8 Nm (71 lb-in) during reinstallation. Dispose of the O-ring seals which were removed from the A/C expansion valve. The reverse procedure of removal should be performed for reinstallation but with new O-ring seals and proper application of clean PAG oil in the refrigerant system. The final steps include evacuation followed by a leak test and a proper charge of the refrigeration system.

The first task when servicing and repairing the A/C Expansion Valve for climate control is to recover the refrigerant. First, remove the four cross vehicle beam nuts while discarding the beam until you reattach it with 30 Nm (22 lb-ft) torque. First, detach the auxiliary evaporator outlet and inlet line fitting nuts while setting the auxiliary lines to the side before discarding the O-ring and gasket seals, which need to be tightened to 15 Nm (133 lb-in) during reinstallation. Unscrew the A/C Expansion Valve fitting nut and throw away the O-ring seals before reassembling it using 8 Nm (71 lb-in) torque. You should untighten and reinstall the two A/C Expansion Valve bolts at a torque of 8 Nm (71 lb-in). Discard the O-ring seals from the A/C Expansion Valve, then remove it from its mounting position. You should uninstall the parts in reverse order while using new O-ring and gasket seals with the proper amount of clean PAG oil. To finish the process, you should evacuate the refrigerant system along with performing pressure tests and system charging.

Recovery of refrigerant should start all processes for servicing or repairing the A/C expansion valve. Tighten all four roll restrictor cross beam bolts to 55 Nm (41 lb-ft) before installation while performing the service and repair of the A/C expansion valve. Fasten the roll restrictor bracket bolt at 48 Nm (35 lb-ft) when reinstalling it. Install the new A/C expansion valve manifold bolt by discarding old O-ring seals while tightening it at 8 Nm (71 lb-in). Install the new A/C expansion valve bolts after their removal by securing them to 8 Nm (71 lb-in) torque specification. Follow the removal process in reverse to install the A/C expansion valve by using new O-ring seals and performing proper PAG oil lubrication of the refrigerant system. Evacuation that includes leak detection and refrigerant system charging represents the final step. The installation of a new receiver/drier requires physical contamination evidence from a failed A/C compressor or damaged receiver/drier condition.
