Hi guys, my retinal detachment recovery is over so I'm getting back to flushing my Esprit I just bought. I recoated the coolant tank because it was rust city and kept even new coolant very dirty. So dirty, in fact, that I wonder if draining and filling the coolant system with CLR and letting it run would be a good idea.. Followed by tap water, then a proper flushing chemical, then distilled water, and finally actual coolant. Thoughts?
