Newbie Question
I am having my coolant flushed today how soon do I need to put in the additive? Also what brand additive does the group prefer? I found Napa Kool but have not found anything else.
Some guys run the stuff from Ford. I personally run the Napa Kool and know of a few guys that have put over 100k miles on their trucks using the Napa stuff.
Napa Kool is the additive you add to the coolant. I can't remember exactly, but I believe it takes a little over 2 pints of it after a flush to bring it up to proper levels.
