Reverse instructions for disassembling the three units, noting the following::

  • clip (1) must be arranged over nearby cable of sensor (2) then fitted to centre of evaporator surface which communicates with distributor heater unit, i.e. sensor must be in the middle of the visable evaporator surface when this is enclosed between the two case halves (as illustrated in figure alongside);
  • contact surfaces of pipe (3) and sensitive bulb (4) of expansion valve must be absolutely clean and the two parts in contact must be insulated by trim (5);

P3M067H01

  • if one or more o-rings require replacement, note that the new rings must be green because only these are resistant to the R 134 A coolant used in the system. Never use black o-rings as these could prove a source of leaks because they are permeable to the above fluid;

P3M067H02

  • evaporator tabs must not be deformed because this would reduce system cooling efficiency;
