Long time lurker here. I live out in the boonies and want to change the coolant in my 1993 f250. I know to use green low silicate coolant now will 2 bottles of napacool do me for sca's?
Napa has fleet guard too. how long is it good for till i have to test. I was given nape strips and I dont see a sca level on the guide.
