Fred, I personally believe a 160-deg. F thermostat used in an effort to =
"cool down" a Healey is useless. A thermostat responds only to the =
temperature of the coolant flowing through it by opening up to increase =
coolant flow, and once it is open all the way at 160+, it is out of the =
loop and can't open further to cool more. I am on the NC coast where =
winters are mild. I once tried a 160 (non-sleeved) because I had one =
that someone gave me. My BJ8 ran so cold that winter that I actually =
had to block part of the radiator to raise it to anywhere near normal. =
Up there in the NC mountains, that would be even more of a problem for =
you.
I use a 187 F (86 C) New Old Stock AC sleeved thermostat (AC part number =
1572320) that I was able to score from lister Kees Oudesluijs. I =
installed it along with an upgraded core in the radiator at the same =
time, so I can't really say how much improvement the thermostat alone =
did; but since the modification my car runs consistently at 170 - 180 in =
the hot summers of the NC coast, except when in stop-and-go traffic when =
it might make it to 190 or a bit above. In winter, it runs at 160 - =
170. I can see the sleeve operate as the car warms up because the gauge =
will cycle between 160 and 190 until coolant temperature stabilizes. =
That can take up to 50 miles.
A friend placed an order later with Kees for several of the 190 F =
sleeved thermostats. I got one of those as a spare. Don't know if he =
has any left, or can get more. As far as I know, the only sleeved =
thermostats available from the usual suspects are 160s and I wouldn't =
waste my money on them.
I just Googled the AC part number and came up with this source:
https://tinyurl.com/y9c6n53h
Unfortunately, it does not post to the USA (but on the bright side, it =
offers free shipping!). Maybe you could work out a deal with a UK =
