I discovered that fact 30 years ago when I decided to drive my '61 BT7
from LA to Canada in January. (Yeah well we're all a little bit crazy
if we own Healeys, aren't we?) Bill Bolton will remember me arriving at
his doorstep.
In preparation for the cold and snow, I upped the antifreeze
percentage to about 80%. I discovered that not only did the car run
hotter, looking through the radiator cap hole, the water pump did not
seem to be pumping as much either. From then on I never ran more than a
50% solution in any car.
