what coolent do my 99 buick park avenue take
It takes regular 50/50 green coolant! Only other type of coolant is a special type used by Toyota. It is red and completely different than conventional antifreeze/coolant. Never use that.
I just purchased a 1999 Park Avenue Ultra. It has Orange antifreeze/Coolant. Should I leave it or have it flush out, and use Green?
