I was told i am suppost to flush My Antifreeze in my Blazer because it turns to mudd or something like that? Its the Orange fluid which my Dad has had in his suburban for years with no problems. My 2004 Blazer is fairly new with only about 70,000 miles on it I scraped the bottom of the tank it was only slightly gunky But the fluid looks ok to me. It was a government vehicle so it was only driven a few hours a day and all the maintnance was done to it what do you all think???
