<DIV>Steve,</DIV>
<DIV>Yes agree with your take on the 160 F thermostats. The only possible
benefit is that if you start with a lower coolant temp, when you hit traffic, it
will take longer before the dreaded over temp zone is approached.</DIV>
<DIV>As an aside, I have installed an oil temp gauge; very useful and a reminder
just how long the engine (not coolant) takes to get up to temp. Trying to get in
the habit of not going over 2000 RPM till OT is about 120F – often another 15-20
mins after the thermostat opens. </DIV>

style='FONT-SIZE: 11pt; FONT-FAMILY: "Comic Sans MS"; COLOR: #002060'>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.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN
style='FONT-SIZE: 11pt; FONT-FAMILY: "Comic Sans MS"; COLOR: #002060'>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.<o:p></o:p></SPAN></P>
<P class=MsoNormal><SPAN
style='FONT-SIZE: 11pt; FONT-FAMILY: "Comic Sans MS"; COLOR: #002060'>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.<o:p></o:p></SPAN></P>

<P class=MsoNormal>I have researched what I can of the archives and other
sources and am still puzzled. I cannot find any real answers and direction
on the question of which thermostat I should use in my 66 BJ8. Some
answers indicate a sleeved thermostat and others say no sleeve. Some say a
short sleeve and others say only the long sleeve works. Some answers
indicate using a 160 degree thermostat while others propose 180 degrees and even
190 degrees. Some even say the Moss sleeved thermostat does not
work.<o:p></o:p></P></DIV>

<P class=MsoNormal>I am in North Carolina and drive the car most of the
year. Right now the car has a non sleeved 190 degree thermostat. The
car starts and needs to warm up, at idle, to almost full temp before it runs
with no problems. Otherwise it spits, coughs and has no power. The
car runs at about 190 degres except when I drive the mountains and of course
stop and go traffic.<o:p></o:p></P></DIV>
<DIV>
<P class=MsoNormal><o:p></o:p> </P></DIV>

<P class=MsoNormal>What is the consensus of thoughts as we approach colder
weather? And what are the sources and manufacturer for a good
thermostat?<o:p></o:p></P></DIV>
