Coolant Mix

[jgtg03172003]

I just installed a coolant filter kit on my 04 6.0 with 58k, from Dfuser.I need to add a half of gallon of gold coolant.Is that coolant already mixed 50/50 or do need to mix it before i add it to the degas bottle.Will it hurt to just add a half gallon of pure collant.Thanks

It's concentrate. So you have to mix 50/50.

I would add the straight concentrate. Although a half gallon of full strength isn't going to make enough of a ratio change to measure I have always done a 60/40 mix.
