Yeah i bought one of those flush kits tapped in to the heater core lines and ran it till I saw clear water (well almost completely clear). I then bought super flush liquid from peak and ran that through the system for a good 30 mins or more. Sucked out all the coolant and filled her back up with Dexcool. Ran the car with the cap off for a good 10 to 15 mins toped off and capped the system. Got some good heat for a day or so now heat is alright, but seems to have gotten colder and a strong smell of dex cool when I turn on the heat.
