The Antifreeze tester is used to easily test for anti-freeze and anti-boil protection. Additionally, the body is clear allowing for visual inspection of rust and other sediments. A vehicle's antifreeze must be maintained at the proper concentration to provide protection against engine corrosion, freeze-ups and boil-overs. Coolant is drawn into the tool and its performance is determined with the easy-to-read gauges on the tool.
