Any one here use Napa cool for there coolant sca's?

[larson]

I bought a gallon of this stuff I didn't think before I left Napa about how much of this stuff ill need. I hope a gallon is enough its 30 bucks a gallon jug. All it reads for instructions is add to glycol based coolants only.
-Do I add the whole jug to my rad? How do you guys recommend I add it in so as its not to rich? I also bought the ph strips that go with the additive
-what's the coolant capacity of the 7.3 idi with OEM rad?

I think the bottles say 1 pint per gallon. If your coolant already shows some sca, just add some every day till you get the level sca level right
