DO NOT TEST HOT COOLANT -- YOU COULD GET BADLY HURT, SINCE THE COOLING SYSTEM IS UNDER PRESSURE WHEN HOT! NEVER OPEN A HOT COOLING SYSTEM (radiator cap, expansion tank/coolant reservoir, hoses etc!) With a cold engine, use a "coolant tester," which is an inexpensive device that lets you sample your coolant and that allows you to determine the "specific gravity" of the coolant. The device may utilize a floating needle or colored balls that correlate to a scale showing the level of protection against freezing. You can get a coolant tester at any automotive supply shop. When mixing G12 coolant concentrate with water (ideally demineralized and distilled), the proper ratio is 1:1 for a VW or Audi operated in a moderate climate. The ratio may be changed between 40% coolant + 60% water (best protection against boiling) and 60% coolant + 40% water (best anti freeze protection).
