The easy way is to buy a flush kit from prestone ($7) and follow the directions. You will basically be splicing in a tee fitting that accepts your garden hose, and adding a can of flush to the cooling system. After 10 minutes of run time you will turn or the hose and 'backflush' the old coolant out the top of the radiator. Messy, but it works. I hope this helps you. Mark
