First leave the old radiator in and buy a Prestone radiator flushing T in any auto parts store. Splice into a heater hose open the drain T in the bottom of the radiator and catch the old coolant in a large oil drain pan. Hook up a garden hose to the T that's been spliced in tour heater hose and turn on the water to the garden hose. Start your car and let idle for 5 minutes. Shut the car off and close the garden hose supply. Let the radiator completely drain and remove it and bolt the new one in.
If you still have the owners manual inside the glove compartment look up the cooling systems capacity in the specification section. If you don't have one go to your local library and look your car up or buy a specialived book on yout car at an auto parts ot book store. You must know the capacity before the next step. First pour in 1/2 the total capacity with 100% aantifreeze. Fill the remainder with distilled water. At this time you may not be able to add much or any water. Put the radiator cap back on and start the car. Make sure the coolant recovery is completely full of the remainder of the antifreeze or distilled water. Get behind the wheel and watch the temperature gage. If it appears to start to get hot shut it off for at least an hour. Water and or antifreeze will be drawen back into the system displacing the air that was locked in as you filled the radiator with antifreeze. Keep the coolant recovery tank at least 3/4 filled when cold with the remainder of your antifreeze and distilled water. After you drive the car for a couple of weeks the antifreeze and water will have cycled back and forth into the coolant recovery tank. Invest in an inexpensive antifreeze tester in any auto parts store. Test the antifreeze from the coolant recovery tank. It should test -35 to -40 degrees below zero.

I always change rad valves on live and working systems but this is in a commercial environment where it just isn't possible to drain down. To do this 'live' takes about ten mins per valve. If I was doing this on a domestic system, I would personally drain down first and power flush the system before fitting new valves.
