[Healeys] heating up

[gradea1 at charter.net]

Go to Harbor Freight and purchase a heat gun (about $20) focus it on
the head and also the radiator. If the readings are different from you
gauge on the facia, send that off to Nisonger as well. If the gauge
reads the same as the heat gun, you need to find out what's wrong with
the cooling system.
Normal temp. is about 185 degrees F. My Healey has never gone above
that, unless idling in traffic...then maybe 200. A 7lb. pressure cap
allow you to go to 219 before you boil...but that's too hot and you
will soon be looking for replacing head gaskets or cracked heads.

Check that temp gauge, maybe clean the bulb in the radiator and adjust
fan belt, but sounds like a flush, new thermostat, maybe a water pump,
and antifreeze are in your future. Regards, Hank

	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.

SUBJECT: [Healeys] Installing a rebuilt speedo  

	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 3rd 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? 

	Also, I am trying to install Led lights. Which should I order from
Moss? The short ones?  

	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.
