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.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;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.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;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.<u></u><u></u></span></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:#002060">I just Googled the AC part number and came up with this source:<u></u><u></u></span></p><p class="MsoNormal"><b><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:#002060"><a href="https://tinyurl.com/y9c6n53h" target="_blank">https://tinyurl.com/y9c6n53h</a><u></u><u></u></span></b></p><p class="MsoNormal"><span style="font-size:11.0pt;font-family:"Comic Sans MS";color:#002060">Unfortunately, it does not post to the USA (but on the bright side, it offers free shipping!).
