Before you begin, release the refrigerant and separate the negative cable from the vehicle's battery. Should the servo for vehicle speed be nearby, remove the servo to reach the accumulator. Unlock the nut holding the liquid line fitting in place, remove it, disconnect the actual fitting and throw away the rubber O-ring. Plug up or cover your router's ports with tape. After that, remove the nut holding the suction line fitting, separate the two pieces and throw out the O-ring seal, putting tape or a plug back in the ports. Get rid of the screws securing the refrigerant lines to the accumulator connector block, separate them and throw away the O-ring seals. Block off each exposed connector on the circuit and the refrigerant line with a plug or tape. Remove all the screws at the
Evaporator connector block, disconnect the block from the evaporator and throw away the gasket. Either plug the opened ports or tape over them on both the connector block and the evaporator. Take away the suction and liquid line assembly from inside the engine compartment. For this process, first put the assembly in the engine compartment, take out the tape or plugs from the evaporator connector block and evaporator ports, properly position the connector block with a new gasket and install and screw it with the upper screw being screwed in first to 11.3 Nm (100 in. lbs). Before installation, slip clean oil on the O-ring seals, make sure plastic washers are set properly and fit the new seals onto the ports of the refrigerant lines. After that, screw the fittings onto the accumulator connector block, each to a tightness of 2.3 Nm or 20 in. lbs. After removing the tape or plugs from the midline connector block suction line port, put a new O-ring seal into place, slide it over the suction line and secure it with the nut to 4.5 Nm (40 in. lbs.). Follow this method with the liquid line fitting, again tightening the nut to 4.5 Nm (40 in. lbs.). Should you have to, put in a new vehicle speed control servo, reconnect the battery negative cable, evacuate the refrigerant system and properly charge it.
