I plan on doing a flush and fill probably at the end of summer. I'll just buy the cheapest appropriate coolant at Rural King.
you dont put the additives in it? or is there coolant available that contains the needed additives for wet sleevers?
I have no idea how old my coolant is.. I opened it up and looked and it and said "yep its pretty green and no swirlies.." and that was it... never thought about its age or any additives..
in the 80s cadillac made wet-sleeve engines and sold an additive tablet you had to add to those when you changed the coolant..
