K-Tool Antifreeze Coolant Tester

K Tool antifreeze testers are designed to gauge your anti-freeze/anti-boil protection. They will allow visual inspection for rust and sediment. It's important to maintain your antifreeze/coolant at the proper concentration to provide good corrosion resistance, as well as prevent freeze-ups and boilovers. These testers provide a quick and easy method to safely collect a sample and measure coolant concentration.
