<div>For an update on radiators and cooling</div>
<div> </div>
<div>This Sunday the GGAHC had their Ice Cream Social in Danville California,
Afterwards I had wine event and a friends winery in Lodi. </div>
<div> </div>
<div>If you havent heard we are in the middle of a major heat wave here in
Central California. The day time temp at noon on Sunday way 105 degrees and
warmed up to a mild 109 by 4 pm. </div>
<div> </div>
<div>Of course since I started out at our Club event I took the Healey. With a
alluminium radiator. </div>
<div> </div>
<div>The engine temperature ran a steady 185 to 190 degrees at 70 mph
</div>
<div> </div>
<div>This is how I like to test something. A real life personal test on
how a part works.</div>

<div style="font-size:12pt;font-family:Century;color:rgb(0,0,0)">
<div>We have been dealing with the British Car industry for only about 70
years, from an independent shop in the 50s and 60s, then a BL dealer in the 70s
and 80s. Then back to an independent repair shop dealing strictly British Cars
the entire time. </div>
<div> </div>
<div>WE have dealt with running hot and overheating the entire time. Up until
about 10 years ago we had been installing a special high efficency radiator core
in all our radiators. We would not paint the cores, change the necks to a short
neck allowing a higher pressure cap, correct thermostats, installed air ducts
correctly. All of these things helped. </div>
<div> </div>
<div>I am personnally hesitant to make changes until I have installed in my own
personal car and actually seen a difference. On my BN4 I have a highly upgraded
motor, a 3000 motor that is bored .060 over, perfomance MSD ignition and much
more. I was continually having hot running problems here in the central valley
of California with the summer temps always in the high 90s and upto 110. </div>
<div> </div>
<div>I removed one of my upgraded radiators and installed an alluminium
radiator, with 2 rows of 1” tubes. The original Healey radiator is a 2 row
core with 1/2 tubes, the upgraded core we have been installing is a 3 row core
with 3/8 tubes with a new style fin. This esentially gave us more tube to fin
area as well as more fin to air surface.</div>
<div> </div>
<div>Now with the newer alloy radiator we gained more tube size, more tube to
fin and more fin to air contact, This making better cooling.</div>
<div> </div>
<div>Now for the test, I installed the alloy radiator in my car, and immediately
the running temperature dropped by about 10 to 20 degrees depending on the day.
However I still had an issue with slow traffic speeds. It was much better
but I wanted to make it better. So I installed a pusher fan on a thermostat set
at 180 degrees, and now all the heating issues are gone.</div>
<div> </div>
<div>So maybe if you compare equal sized radiators with equal fins and tubes,
the copper brass radiators are better. But my own personal test in my car proved
to me that the alloy radiator was the cure.</div>

<div style="font-size:12pt;font-family:calibri,helvetica,sans-serif;color:rgb(0,0,0)">I
do not have any experience with aluminum radiators but I have tried oil coolers,
"Texas fans", and electric fans. I finally had my original recored with a core
that has extra rows. The upper tank is original but the lower is thicker, which
made installation a little challenging. The radiator has been in for at least
15-20 years. I have driven under almost every condition- very hot ambient
temps, high speed (80-90MPH) traffic etc. and the engine temps stay where they
should be. Strongly recommend this option, especially since it almost
impossible to distinguish my radiator from the stock original and it has worked
to perfection. </div>

<div dir="ltr">My 100 radiator is in need of some
rehabilitation. It either needs to be boiled out, which would not replace some
of the damaged fins, or re-cored. I am leaning toward re-coring but that would
be more expensive, which leads to the aluminum option. </div>
<div dir="ltr">Besides price what are the pros vs. cons of
these options? Does anyone know if re-cored 100 radiator is more efficient than
an aluminum radiator?</div>
