coolant info needed

I understand that we need the coolant not to freeze or overheat like water will. Can someone explain the additive for corrosion? I never used test strips before. I guess the additive is dca4 or something like that. Am i ok if I check the freezing point with a checker then just add additive?

I got test strips from NAPA. Came in a container with 50 if I remember. I can't seem to find them right now. The additive prevents the coolant from cavitating which will in effect "drill" a hole in the walls of your block. I will post more when and if I find my strips.

I just Googled "7.3 Coolant Cavitation" and got tons of reading. Do it and see if that doesn't give you the information you are asking for.

I googled it but did not find what i need. I, from this site, have heard of test strips. Do they come with directions on what the readings should be?
Is this for all diesels or just powerstrokes? Cummins too?
Other than replacing the coolant, how do I know if its good? Do not want cylinder issues. If an additive is needed is their only one? the dca4?
thx

Yes they come with instructions and a color comparison chart. It's like testing the pH in your swimming pool. You know, match the colors. Go buy some and it will answer all your questions. Try NAPA. That's where I got mine last time. Good luck.
