I have just made the switch to CAT ELC coolant in my 7.3 Powerstroke and im planning on doing the same for my idi very soon. I bought a case of 6 gallons already pre mixed for like 80 bucks with tax I think it was. With the CAT ELC their is no need for adding SCAs and using test strips.

Any of the ELC coolants should work as they are precharged and are good for 3 to 400'000 miles of onroad use before they need an additive. Thats way longer than than I would let the coolant stay in my system and probably longer than our trucks will last on top of the miles they probably already have. You may see Final Charge Global on the shelf at autozone, its made by Peak and FWIW I run that in the DD15 in the semi I drive at work.

I should do a coolant flush in the spring then and put the right stuff in. I was hoping I could just put some SCA in but from reading that it looks like I would be doing a coolant flush anyways to get a 50/50 ratio of coolant to distilled water.

cat antifreeze kicks a$$. we overhauled a c-12 Cat with that coolent in it and there wasnt the least little bit of rust or scale in the cooling system that we could find. i however just use the standard green napa antifreeze and charge it with Napakool. its alot cheaper for me, and it dosent take much to check it with a strip.
