That's sounds like a great plan ~ I only wish you had posted that you flushed the cooling system too ~ if it's not too late DO IT before putting in the K-Seal... I looked down the radiator cap hole into my radiator before & after doing the flush with Prestone Flush Cleaner $5.00 AND I'll be darn it really worked... All of the waterway passage slots were clean & open not like before the flush when they were plugged with crud... It worked..!
The reasons I started using 50/50 premix coolant: (I never did before & never got flu shots either NOW I do both 50/50 & get flu shots)
1) Laziness is the mother of invention ~ it's so easy, just open & pour ~ no farting around mixing stuff or driving around searching for distilled H2O
2) If the only coolant you put in the radiator & OF tank is 50/50 then the cooling system will always be 50/50 mix, nothing more, nothing less..!
Going to post in Fusible Link Now
Hope K-Seal works with 2 bottles or less (Flushing might remove the K-Seal & make the head leak again..? Flush it first...) K-Seal might block off water passages that are partially already blocked with crud & scum.
Best of Luck --
