Howdy, first post here because I couldn't find an answer anywhere! I have a 2013 1500 5.7 Lone Star with 120,000 miles on it. I am the second owner and have been planning a complete flush of the coolant system. I have my OAT and distilled water, but before I started I noticed some scale build up in the radiator. I would like to make sure I get everything nice and cleaned out, is there any flush cleaner (besides mopar radiator kleen) that is recommended by Ram? Thanks!
