Going to do a coolant flush and was told by a friend who works at GM that they reccomend using their cooling system sealer additive which is these 3 brown pellets. I have never heard of these on this board. Any thoughts? If i should use them do you desolve them in your coolant water mix before adding to radiator? Thanks.......
