Once again my Dexcool anifreeze has turned to mud. I already had it flushed at 40,000 miles, now again at 80,000. It's supposedly rated for 150,000 miles. I also had to get my gaskets replaced because they were ruined from the sludge. There is a class action lawsuit against GM for its Dexcool antifreeze, however, the 3.4L V6 is not on the list although I have the exact problems. They said there were not enough complaints. If you have Dexcool and have had to do radiator flushes, replace gaskets, experience over heating or replace heat cores.....Make a complaint. Try to get the 3.4L V6 on the list.
