Antifreeze concentration cat elc
I have cat elc in my 03 with a coolant filter. No problems to date coolant wise, I have my truck in changing fuel filters and thought I would check the freeze point of the antifreeze, and it went to -60f. Now it does not get anywhere near that cold here, -25 is the coldest actual temp I have ever seen. Is it hurting anything cooling wise having it too concentrated?

Learn something every day, real temps hit -40 easily, this morning was -41, didn't even bother moving the truck because absolutely nothing likes that temperature.

If you look at the chart pure glycol coolant freezes at a pretty high temp, around +20F or somesuch, it's the addition of water (to the ratio of 50/50 say), that gives us the -34F below zero freeze protection.
Windchill won't lower the temperature of anything, people or otherwise that's true, but what it does do is cool things off a hell of a lot quicker to ambient and/or keep them from warming up. Even an unheated shed will keep a truck somewhat warm(er) overnight after shutdown at least in terms of starting, but out in the open (wind) will quickly cool off. Every bit helps in extreme cold.

The actual black and yellow jugs of cat elc I got said do not add water. So I guess that makes it premix

Best way to check is with an antifreeze hydrometer. It will tell you if it is 50/50 premix. It's actually prefered to do rinses with deionized water several times and then add 100% concentrate until it is down to 50%. But if you drained only, just add premix and then top off and run. But you have only changed about half the fluid remaining in the block and probably could do it again in a bit.....
