Why did you need to lower your coolant temps? Creating a larger opening in the grill block, or using the correct thermostat is the proper way to control coolant/engine temperatures.

Water is an extremely good fluid for both conducting heat, and absorbing large quantities of energy.

Water Wetter's website shows how good water is in their chart. You'll notice the chart compares water to many substances, but not Water Wetter.

If I lived in a climate where extreme freezing was not a danger, I would lower the antifreeze ratio to something much lower, perhaps to 20%. This would greatly increase the heat capacity and thermal conductivity of the coolant.

How bad does it freeze in Texas?

Water Wetter is a detergent, so it breaks the surface tension of water. It reduces the viscosity of water.
