  Q: How to service and repair the A/C Expansion Valve in a refrigeration system on Toyota Solara?

  A: The expansion valve requires two main steps for servicing: first discharge the refrigerant through the refrigeration system followed by disconnecting the liquid and suction tubes from the A/C unit. Remarkable service requires you to extract these elements by pulling out the packing material while employing a 5.0 mm hexagon wrench for bolt detachment from two points and tube separation. Immediately protect open fittings from moisture and dirt intrusion. You need to apply ND-OIL 8 or equivalent compressor oil to two new O-rings before installing them on the valve before attaching the tube with its accessory to the expansion valve. The installation bolt hole must remain visible on the tube side by leaving packing paper untaped while you apply the packing to the expansion valve so it extends only to its edge. Two new O-rings require lubrication with compressor oil before they are installed on the evaporator using a 5.0 mm (0.20 in.) hexagon wrench and 2 bolts. Apply torque force of 5.4 Nm (55 kg.cm, 48 in.lb) but avoid packing material from jamming against the evaporator. The expansion valve requires additional packing paper removal before receiving its packing application. Installation of the blower unit should be followed by connecting liquid and suction tubes to the A/C system before charging the unit with refrigerant beginning with air evacuation and using an 800 plus or minus 50 g (28.22 plus or minus 1.76 oz.) amount. Gas leak detection should be performed to check for refrigerant loss followed by checking pipe joint and clamps for proper torque when leakage is discovered.
