Neither, really, modern wax pellet thermostats open much quicker (over a
smaller temperature range) than the old aneroid ones did.
I've talked before about the pitfalls in looking at shop manuals to
determine what parts should be on your car ... here is another example.
According to the TR4A factory Spare Parts Catalog, the 4A used a non-sleeved
thermostat, P/N 140970. I don't have specs for that one, but I do have a
factory supercession list that shows P/N GTS111 as a replacement, which is
an ordinary, non-sleeved, 180F (82C) thermostat.
