There should be a white petcock on the bottom side of your radiator. Make sure you have a catch pan to collect the fluid. That **** is toxic to animals and it is sweet so pets are attracted to it.
Make sure you remove the radiator cap so you get air flow through the radiator.
After you are done, refill your radiator with a 50/50 mix of coolant and water. If you haven't done so yet, buy a Haynes or Chiltons manual for your model year. In it will be the fluid capacities for things like coolant, oil, and other things. Best $20 you could spend.
