[Healeys] Proper Thermostat for a BT7?

[Jack Feldman]

Somewhere I read that the 3000 takes a special thermostat. I asked a
representative of a LBC repair shop and he confirmed the information and
gave me two part numbers. There were Stant 13358, and 13008. I went to my
local NAPA store and they translated those part numbers into NAPA 169, and
170. Both of those thermostats looked exactly alike, and both were 180
degree thermostats. The were so much alike I'm not even sure I got the
correct part in the appropriate box.

When I looked at them out of the box they just looked like any old
thermostat.

Do we really need a special thermostat? If the part numbers that were given
to me are correct, what is special about these thermostats?

My MGC has a special thermostat, but the difference is obvious.

Thanks,

Jack
