flushed the coolant using 6 gallons of distilled water {9 drain and refills}and added the new Prestone"all makes and models" fluid. while doing this procedure,the tiny o-ring on the drain c*** of radiator split from old age and caused a slow leak of water from radiator-local dealer of course didnt have o ring in stock,so off to local hardware store where i performed last drain of distilled water onto their parking lot,took drainplug into store and matched up new o-ring{.39 cents} and reinstalled plug and added coolant! moral of story,get a new o-ring before attempting coolant flush on your Q.
