If your radiator does not have a drain plug you are going to have to remove the lower radiator hose. To add coolent flush remove upper radiator hose and pour into hose and reconnect.

If you're not having any issues with overheating or running hot, I wouldn't. Something is bound to start leaking. HTH. -Jim
