<P>OEM thermostats when fail they do so closed. With other thermostats it can be
open, closed or in between. Anyway when a thermostat fails, which is not very
often, you soon notice the result on the temperature gauge!!</P>

<P>One other consideration: I have heard--note: hearsay--that the OEM

<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

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>
