Check that your vehicle is protected with this easy to read indicator, designed for modern Ethylene Glycol antifreeze. Number of floating discs indicates level of antifreeze protection. Tests at hot and cold temperatures and reads in Celsius and Fahrenheit.

Floating orange disc shows over protection and loss of efficiency. A solution of more than 70% antifreeze will give LESS protection. Pure antifreeze will freeze at -6° F
