That said, the thermostat will gradually open as the coolant reaches the thermostats full open temperature. So, if you drive in a colder climate, you might want a thermostat with a higher opening temperature, say 180, in a warmer climate you might want the 160 or 165. I think I have a 160 in my car and it is fully warmed up and running without the choke engaged when the temperature gauge reads 190.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>John Spaur<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>’62 BT7<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #E1E1E1 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'>From:</span></b><span style='font-size:11.0pt;font-family:"Calibri",sans-serif'> Healeys <<a href="mailto:healeys-bounces@autox.team.net">healeys-bounces@autox.team.net</a>> <b>On Behalf Of </b>Richard Antal via Healeys<br><b>Sent:</b> Wednesday, September 17, 2025 11:33 AM<br><b>To:</b> Healeys <a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a>s<br><b>Subject:</b> [Healeys] radiator thermostat<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'>Gents,<o:p></o:p></span></p></div><div><p class=MsoNormal><span style='font-size:10.0pt;font-family:"Helvetica",sans-serif'> What is the desired coolant temperature for optimal engine performance?
