One other thing: if you live in a warm climate, you can use less
antifreeze in your coolant mixture. I live in the SF Bay Area, and
it (almost) never freezes here, so I use about a 2:1 water:antifreeze
mixture. Water has greater thermal conductivity than antifreeze, so
your cooling system can dissipate heat more efficiently. The
antifreeze bottles usually have a graph or chart showing protection
vs. concentration.
I also put Water Wetter in occassionally, but I can't say
definitively if/how much it lowers the temp.
