<DIV>David,
<DIV>Do you use an antifreeze mix or just water and anticorrosion

<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>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>

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>
