Palehorse86, I have the ISC 300 hp. I didn't mean to open up a can of worms. lol I was just wondering if anyone had switch antifreeze and how much trouble it was. I'll just stick to what Cummins, recommends. To change would be much more trouble then it is now.
Thanks to everyone who has given input on this. I have learned a great deal of information from this great site, keep up the great work.
Thanks to everyone and Merry Christmas to everyone.
