I did follow the link and running 70% coolant is just plan ridiculous. You
can run 70% coolant, i'll stick to my 70% water. Over the past 20+ years,
I've never heard of anyone actually running that high of a mix. (And I
wasn't cheated...I'm not in that line of work anymore.)
And yes, I think we should let this thread die...we're starting to run out
of "RE:" spaces.

Uhhhh...using a minimum of 25 service manuals (actually quit at 27), making
especially sure to span vehicle recommendations to include mid to late 80's
(the years of "The
>schools that I had went to"), I have concluded that you were bernd and
unscrupulously cheated. Your schools outright lied to you! All manufactures
recommended a minimum of 50/50 water/coolant mix. Oddly they all gave the
same reasons Prestone gives in their FAQs. Since you didn't follow the link
(http://www.prestone.com/faq/faq.html) to it I will paste it in here....
"Q: What is the best antifreeze/coolant concentration for a vehicle? Can I
use 100% antifreeze?
A: We recommend that you use between a 50% and 70% concentration of
antifreeze. At least 50% is necessary to give the adequate amount of
corrosion protection, as well as freeze/boilover protection. However, we do
not recommend more than 70% antifreeze. This would cause restriction of the
heat transfer capabilities, corrosion protection, and freeze protection. The
concentration of freeze/boilover protection of the antifreeze mixture can be
checked using Prestone® Test Strips or a Prestone® Coolant Tester"
