My God I hate this attitude both on this site and in life in general. We do it this way and how dare you question! Look just because the military does one thing doesn't mean that is the only way to do it. In the world of civilian heavy trucks there are a 100 ways to approach any issue and don't think for a moment it is any different on an m923. There are about a half dozen of you guys who wade though the forums with your mighty sticks of justice. It is irritating. I could pay to have my wheels balanced but I don't. I could pay someone to change my oil, mow my lawn and wash my cars but I don't do that either. This is an open forum, that means us too. Here we are minding our own business hashing out an issue and in you come to call us all stupid for not doing it your way, the TM way. At the same time half of you are running additives, those are not in the manuals either. When I looked into fluid balancing my tires on this forum all the threads had someone come in with the same message of doom backing everyone who was thinking about down by well calling them stupid for trying. That wasn't good enough for me. I decided to try it, I looked up the main components of fluid balancing compounds, found a close substitute and did it. Then (and this is the important part) I came back and reported how I liked the results and how I did it to help others make their own choices. I am a firm believer in letting other people make their own choices.
I have no idea what antifreeze will do to CTIS but I know component wise it will not hurt anything. Oh you might have to blow the whole system out and flush it but there is no way it will 'harm' any of the components, it is designed not to. So even at the worst case, what is he risking, a day of breaking down tires? An afternoon of pulling fittings loose and blowing them out with a compressor and a little shot of airline fluid? Your acting like this will involve flaming debris and dead school children. Relax, grab some popcorn and watch us fail. They are our trucks, it might work, it won't hurt you and we could all learn something. At least we go out and try something and report back success or failure rather than talking about it. If he wants to try it and report back to us, I think that is great of him. He assumes some risk sure, he knows that. Thats what the group needs to learn as a team. Will it work, idk, but I see how it could work and in a few weeks we will all know. Personally I still lean towards airline deicer for a CTIS truck but I would call some big logging shops. I promise you those guys have tried about every tick to keep things rolling. Remember to call a few if you do.
