If you must do it yourself ensure that you drain and capture all the old coolant. There is not a drain cock on the system. You must use the rad hose disconnect. The dex coolant does not like air. It is well worth your while to get a shop with an evacuation flush unit to replace the coolant. This method pushes out the old coolant with the fresh stuff. Effective and mixed to the proper proportion to maximize the long life of the Dexcool.
If you have coolant exchanger take radiator cap off drain as much as you can along with reservoir. Remove upper hose clamps take hose off drain any excess then lower hose from radiator drain that. Otherwise Drain plug at bottom of radiator and a "oil pan" which can be used (if clean) for coolant. Should work well enough then remove hoses and other lines. If you are replacing radiator and doing this in driveway expect an hour or two if you are just starting out with stuff like this.
You should not need to bleed coolant. Ever. If the coolant is filling up on its own the stuff in there is not coolant and you have a big problem.
