Old rad out, autoyard one in! I've been flushing for the last couple of days, and I am still not running clear. I'm going to go grab the flush T today. Obvious rust in the block and some scale in the autoyard rad. What kind of flush product would folks use for scale and rust? I've read that some use restore and restore +. I've rearched vc9 and could only find specifics for the powerstrokes. Which stuff is best in our idi's?
Edit: I'm pulling the block plugs every other flush cycle because it's a pain in the butt.
