[QUOTE="jestal, post: 120114, member: 477"] Not to belabor this EG/PG thing too much but those using propyleneglycol coolants should know that you CANNOT use the floating ball or floating needle type of hygrometers for checking your concentration of coolant. The specific gravity of PG is different than EG and the meters will be in error. You MUST use a refractometer to check the concentration of propyleneglycol systems. That is the only way to measure it. [/QUOTE]
