If i remember right, you need to completely drain all fluid from your system and use another product to remove the last traces of moisture. Evans is not at all compatible with water.
Also this fluid expands a lot meaning you have to go zero or low pressure in the cooling system.
If you were racing a high rev motor or turbo rotary this may be of use, other than that it's really not necessary.
