I use the Evans coolant. It works very well, with no boil over issues even under the most demanding conditions. A few key things with the Evans coolant...

1) get all of the water out of the system before you use it.
2) allow room for expansion - do not fill the cooling system too high

I back the radiator cap off a bit to run at a lower system pressure.

Regarding DEX cool or any other coolant, NEVER mix different colored coolants in even small quantities as some of the combinations are very corrosive to aluminum.
