Way back in the beginning of the TR-2 there was along extension onto the
radiator. It proved to not work too well as this vibrated and cracked at
the radiator tank (my car 1954) and all the water fell out on the ground.
Maybe work and last better if you plan a support.
In all my cars on the 1958-1972 era of Triumphs I had no header tank, filled
the system through the heater hose connection at the back of the head from a
tall filler funnel (about a foot high) and kept the petcock on the thermo
housing open until water shot out, closed the petcock, then quickly pull out
the funnel and replaced the plug. this eliminated all air in the system
which is paramount.Never lost any water expect when a head gasket was blown
and nothing would have helped that condition.
