Never used any, in this car anyway (for emergencies only, IMO). It was 
solder.

        <div>One thing it might be is stop leak.  Stop leak can plug up
          a system if there's air in there somewhere, and stop leak will
          form clumps if you don't drive the car every day.  Using stop
          leak is fine, but you have to flush the system out thoroughly
          after the stop leak has plugged the holes in your system.

                    not sure--was selling a Robertshaw thermostat with a
                    brass sleeve soldered to it (Robertshaw thermostats
                    have a center portion that moves up and down). The
                    one I bought was 160deg; I desoldered the sleeve and
                    soldered it to a 180deg Robertshaw. I bought one of
                    the original, bellows-type from Kees--whatever
                    happened to him?--but never installed it; heard they
                    were the 'fail closed' type, which could turn a
                    minor failure into a catastrophe (still have it
                    around somewhere).<br>

                        <div>Thank you, now I understand how the whole
                          thing is supposed to work.  The sleeve works
                          to cut off the bypass so that hot water is not
                          recycled into the system after it warms up. 
                          FWIW, this only applies to the 6 cyl, the 4
                          cyl doesn't have any sort of bypass.<br>
                          <br>
                          Yes, I think it would be great if you could
                          share with us which thermostat to purchase and

                                plays an important but problematic role
                                in the Healeyâ??s cooling system. When the
                                thermostat is closed coolant returns to
                                the water pump via the bypass. See the
                                red circle on the attached picture. The
                                bypass is important for three reasons:
                                its allows the coolant in the block to
                                continue to circulate and come to a
                                uniform temperature before the
                                thermostat opens, it prevents hot spots
                                that could develop from stagnant coolant
                                and it prevents the water pump from dead
                                heading.</p>

                              <p class="MsoNormal">The problematic part
                                is in the original design the bypass was
                                closed by a sleeve on the bellows type
                                thermostat when the thermostat opened.
                                The original Bellows type thermostat
                                used a volatile liquid and were not
                                reliable and were not suitable for the 7
                                psi cooling system pressure. Wax type
                                thermostats are much more reliable but
                                they do not have a sleeve to close off
                                the bypass. There may be some expensive
                                wax type replicas of the original
                                bellows type.</p>

                                                cover the bypass port
                                                when the thermostat

                                                then I have another wax
                                                thermostat and the
                                                sleeve actually cover
                                                the bypass when it is
                                                cold, and doesn't cover
                                                it when the thermostat
                                                opens.... so it works
                                                exact opposite to the
                                                old bellows style
