<p class=MsoNormal><span style='color:#1F497D'>Bob, I had continual problems for
years with “overheating” –as indicated by a gauge that wanted
to hover around 200 in traffic on hot days. 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='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"'>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. Have any of you
found success with this modification?<o:p></o:p></span></p>
