I just installed a bigger Shur-Flow type pump on my IC system and noticed that it foams the antifreeze almost instantly. What additives or mix ratio have been used or tried to cut down on this? I am currently running 50/50. I am going to try 100%. Has anyone else had this problem? The system is only what 1.5 gallons or something and with that big pump pushing 5-10 gpm.
