Hi Darryl,
Here in Vienna in Austria the highest temperatures in summer stay =
between 35 and 38 deg. C, but may go down to minus 15 deg C in winter. =
Therefore the temperature range is even higher. But I have to admit, =
that my BN1 stays in the garage from the day of the first ice or snow =
every year until sand and salt are gone in spring. But the lowest =
temperatures at which I have driven the Healey were around 0 deg. C.
Of course regarding overheating your higher temperatures are the bigger =
problem. Here the combination of summer temperatures and driving up into =
the mountains might be a similar challenge for every car.
=20
Nevertheless I only had overheating issues due to problems with settings =
on the carbs or the distributor or in the time before I had to rebuild =
the motor (bearing at crankshaft and the rockers were the main reason). =
During the work on the engine I had a high efficiency net installed in =
the radiator and run our usual antifreeze. Everything else is standard.
=20
Your solution with the metal plate sounds very interesting. Do you have =
pictures? What kind of metal did you use and how thin is it?

G'day to All,
I live in the Riverina district of New South Wales where temperatures go =
from minus 3 degrees C (24 degrees F) in winter to 42 degrees C (104 =
degrees F) in summer which, I think you will agree, is a large variance. =
=20
My '67 BJ8 is running the original radiator, Texas cooler fan, sleeved =
thermostat, original water pump, Lucas D25 distributor and standard =
coil. The engine is standard although 30 thou oversize. I run a 7lb psi =
radiator cap.
=20
I run de-mineralised water and Penrite Classic coolant (which contains =
no anti-freeze) but has the ability to coat all cooling surfaces and =
make (I know this sounds silly) the water wetter and a electric fan in =
front of the radiator.Which, I may add, I have used very rarely over 6 =
years of ownership.
My temps usually run from160 F to 190 F all year round with of course an =
increase to 210-212C on heat soak.
=20
The one thing that I have fitted, (which is definitely not original) is =
a thin metal plate, a great idea made by a Healey mate of mine, that =
fits from the bottom edge of the lower front beaver tail to the front of =
the main cross-member with tech screws attaching it. It covers the =
entire bottom surface underneath of the radiator and part of the sump.
The idea being is the fan draws cool air through the radiator, heats it =
and then pushes the heated air down which can lead to the radiator =
re-breathing the hot air again. The idea apparently is not new, DHMC =
apparently used it on some of the Sebring cars.
=20
I can tell you that it definitely works and allows your Healey to keep =
its cool!
Happy Healeying,
Darryl
