Something New: RR's Question of the Day
I am proposing a question of the day to deal with general automotive engineering topics, as this Forum often demonstrates participant ignorance of same.
I will state the Q, allow adequate time for those that want to propose an asnwer, and then post the correct answer. Might be fun, and educational. We will see.
Question of the Day #1:
Is my cooling system at maximum thermal efficiency with a 50/50% blend of wsater and coolant?

My refuge and reasoning:
"Better be ignorant of a matter than half know it."

I consider my sum total of knowledge to be where to add the anti-freeze!

A much higher perecentage of water would give better cooling efficiency especially in hot summer months, add in some Redline Water Wetter for even better efficiency; but that not the mix I want in my car here in NY in freezing winter temps = cracked radiator and much worse.

I know I will be corrected if I am wrong.

The correct answer is: Wrong! Hyde and Rockin' have most but not all of it.
Water has a higher thermal exchange rate, and thus is a more efficent cooler than "coolant".
As has been pointed out, the issue of lower boiling point and higher freeze point argue against fulll time use except in certain circumstances (temperate climate, racing, etc.)
The issue of water pump seal lubrication, anti-cavitation (foaming) agents, and anti-corrosion additives also figure into the mix, if you will pardon the pun. Adding Water Wetter would help (actually helps any coolant).
In the next question, we will examine the question of if 50/50 is good, is 100% better.
Ta ta.
