<html><body>Go to Harbor Freight and purchase a heat gun (about $20) focus it on the head and also the radiator.

<p class="MsoNormal"><span>Bob,
that seems terribly hot to me. My BT7 often runs around 170
in regular summer weather but even on the hottest days never goes
above 185. No electric fan – just a bog standard cooling
system, which is sufficient up here in Ontario.</span></p>

<p class="MsoNormal"><span style="font-size:14pt;font-family:Arial, sans-serif;">So over the
summer I had the speedo rebuilt by Nisongers. It looks brand new
and works. First time in 15 years I have a speedo.
Although my algorithm of add 15 mph to the tack number gets you the
approximate speed in 3<sup>rd</sup> gear over drive. I am now
trying to install the speedo permanently into the dash and having
problems remembering the wiring. As there are 2 wires with a
circular ground connection, I should attach one to each holding
spade? Has anyone got a picture or sketch of the back of the
dash?</span></p>
<p class="MsoNormal"><span style="font-size:14pt;font-family:Arial, sans-serif;"> </span></p>
<p class="MsoNormal"><span style="font-size:14pt;font-family:Arial, sans-serif;">Also, I am trying
to install Led lights. Which should I order from Moss? The
short ones? </span></p>
<p class="MsoNormal"><span style="font-size:14pt;font-family:Arial, sans-serif;"> </span></p>
<p class="MsoNormal"><span style="font-size:14pt;font-family:Arial, sans-serif;">Also, when
ordering some parts from British Car Specialists I was speaking
with John and mentioned my overheating problems. Besides the
normal suggestions, He mentioned the radiator cap has to be for a
long neck British radiator. I when to my car and the radiator
cap was a standard USA Stant, so I ordered the one he
suggested. Yes, it is ¼ inch longer than the stant and put it
on the radiator and when for my 25 mile drive on Tamiami Trail and
back. The water gauge went right up to 212 and then to 230,
but, settled down to 212 for the rest of the trip without operating
the electric fan. While driving at 30-40 through my
neighborhood home with the fan on the temperature stayed a little
over 212 degrees. Hopefully, this temperature range with
continue as I slowly get my Healey operating well enough for longer
trips.</span></p>
