Cool-Trak coolant test strips is a easy and reliable way to test engine coolant effectiveness. With one simple dip, you can determine an engine's protection against freeze-up, boil-over and acid buildup with a highly effective pH test. You can also use CoolTrak to determine when to send coolant for recycling and to check recycled coolant for effectiveness. CoolTrak has been proven effective with the US military and has been approved for use by the U.S. Postal Service and municipal vehicle maintenance centers across the country.
