First break loose the TXV manifold and tube bracket bolt before tightening it to 8 Nm (71 lb-in) when reassembling. You should disconnect the TXV manifold with tube assembly from its wire harness clip before you take off the fitting nut that connects the condenser-to-evaporator line and discard the gasket seal then tighten the fitting to 15 Nm (133 lb-in) when reinstalling it. The next step includes removing the compressor manifold and tube suction fitting nut until the connection separates while disposing of the gasket seal before reinstallation at 15 Nm (133 lb-in).
