Antifreeze now that is something we can talk about.
In North Ala we can drive our Cobras in the winter, on the sunny days of course. Sometime in temperatures in the low 30's. We do a Turkey Day Run every year and New Years day if it not raining or snowing. It's like those crazy people who jump into a river on New Year Day. Hummm, we must be crazy too.
We have found that a mixer of more than 50%
antifreeze causes overheating.
So we run about 25% to 30%
antifreeze year round.
Our shops and garages will be 40 degrees to 55 on a cold day. So no problem with car freezing up.
Now a radiator at 60 mph on a 34 degree day, I don't what the wind chill is but IT'S cold. Hell, in my book anything under 50 is freezing.
The dash gauge will read a little cooler than normal but not a lot, after you have driven for a while.
Distilled water is a must. We have to much limestone in our tap water.
If you drive a roadster on a cold day, all the people that see you know you are some kind of nut. But it's still fun
