Unless the motor is full of junk and the coolant comes out brown with rust you can flush it without removing the plugs. You may want to remove the thermostat to do a thourgh job. If you want to do a good job you might consider removing the hoses on the pipes under the car. That way you can flush the motor independantly of the radiator and do the radiator separately. You should also flush the heater core. Flush until the water runs clear. After flushing, drain as much of the water as you can. Reconnect the hoses and fill with 50/50 water and anti-freeze into the expansion bottle. Pressurize with a coolant tester and bleed through the bleeder screw on the thermostat housing and the small bleeder hose on the top right side of the radiator. Don't allow the tank to empty or you will have to start over. When you finish up the tank should be between 1/3 to 1/2 full. Before doing all of this you should replace all the hoses and fix any leaks. Look at the radiator through the shroud and fans. If you see any green then the radiator should be replaced.
