Hello marty973-- I have two good links for you. One says that you shouldn't flush. You should drain and refill. The other says that a good flush is good for your cooling system. Try http://www.trustmymechanic.com/htmlmessage12.html and then take a look at http://www1.excite.com/home/info/learn2/tutorials_qa_overview/0,14899,auto_714_0,00.html. Have fun doing it. Good luck from Bovan.

Get it flushed. You will have to remove the thermic valve under engine hose pipe connctor and keep tab water hose in radiator for at least 15 min at high speed.
