What has a greater heat displacement property water or dex-cool...

water exchanges heat much better then antifreeze.

Dex-cool is added to not only lower the freezing point, but to raise the boiling point. Also modern coolants have a greater heat transfer coefficient than pure water.

So do I mix water/dex to save money? Why not run it pure? I know I cant run water pure...And how do you guys know? Thanks for the help...

I am just trying to learn.

You cant run %100 water because it will freeze. You have to have some dex cool in there. Safest is a good 50/50 mix of water and dex cool. And if thats not cool enough then get some Redline water wetter.

It wont freeze in June will it...
I cant run %100 water because the dex lubes the water pump is what I thought.

I run as little coolant as possible in the mix. The less antifreeze the cooler my car runs with the waterwetter, I use about a 75/25 water/dexcool mix. If it didn't get cold in the area I lived in Id run straight water, and I have ran that during the summer a couple of times b4.

Car & Driver's current issue has a good editorial on coolant. Check it out...
