Look up in Haynes manual or Chelton manual. I think all you need to do is start car, turn heater on full blast, open drain at bottom of radiator and drain all fluid out making sure the car does not overheat. Then let cool off and fill with mixture of antifreeze and water then if you want to make sure do it again- this is a guess how to do.
