I tried a lot of things that either didn’t work at all or seemed to make the problem worse. The only thing that finally fixed it was (1) calibrating the gauge to make sure it was accurate (immerse the sensor in boiling water and adjust the needle to lie between the two dots on the gauge at the 212 degree mark. Mine was reading a bit high; (2) having my stock radiator re-cored with a more modern core ($444). Any competent radiator shop will know how to do that to improve cooling; (3) installing a 190-degree sleeved thermostat. I have neither a pusher fan or a “shovel”, but I do have a Texas Kooler fan. It’s normal for a Healey gauge to read 212 after the engine is shut down when thoroughly warmed up, but not while driving down the road at 2000 – 4000 RPM.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>In cooler weather my gauge will run at 165 – 170 when the engine is fully warmed up, and on hotter days and in traffic around 180 – 190. It goes to 212 when the engine is shut off, like almost all other BJ8s I’ve paid attention to. <o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>I avoided having to pull the gauge out of the dash to calibrate it by using a portable Coleman propane-powered stove to heat the water and supported the stove on a wide board laid across the fenders, positioned so the sensor could be immersed in the water.<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Steve Byers<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>HBJ8L/36666<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>BJ8 Registry<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>AHCA Delegate at Large<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'>Havelock, NC USA<o:p></o:p></span></p><p class=MsoNormal><span style='color:#1F497D'><o:p> </o:p></span></p><div><div style='border:none;border-top:solid #B5C4DF 1.0pt;padding:3.0pt 0in 0in 0in'><p class=MsoNormal><b><span style='font-size:10.0pt;font-family:"Tahoma",sans-serif'>From:</span></b><span style='font-size:10.0pt;font-family:"Tahoma",sans-serif'> Healeys [<a href="mailto:healeys-bounces@autox.team.net">mailto:healeys-bounces@autox.team.net</a>] <b>On Behalf Of </b>Robert Begani<br><b>Sent:</b> Monday, January 13, 2020 6:36 PM<br><b>To:</b> <a href="mailto:healeys@autox.team.net">healeys@autox.team.net</a><br><b>Subject:</b> [Healeys] Over heating and adding additional core tubes to the existing radiator<o:p></o:p></span></p></div></div><p class=MsoNormal><o:p> </o:p></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>Listeners:<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>I have added a electric push fan to the radiator and a shovel or deflector to direct the flow of the air to the engine. It works to keep the coolant temperature at or below 212 degrees when driving down the road at 2000 to 4000 rpms. However, the coolant temperature will rise if you drive slower or stop and go. While I believe there is nothing wrong with the radiator, I believe it needs more cooling capacity. How many more core or tubes can be installed in the standard BJ8 radiator. For those of you who have done this modification, how much does it cost and does it work to reduce the coolant temperature? I would rather not install an aluminum radiator because they do not seem to work or do not reduce the coolant temperature.<o:p></o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'><o:p> </o:p></span></p><p class=MsoNormal><span style='font-size:12.0pt;font-family:"Arial",sans-serif'>Another modification I am considering is a manifold and header blanket to keep the heat from the exhaust from boiling the fuel in the float bowls.
