Custom Accessories Antifreeze Tester

The Custom Accessories Anti-Freeze Tester helps make it easy to see if a vehicle’s coolant or ethylene glycol needs to be changed. Inside are floating balls that stop at different points on the gauge to show the amount of anti-freeze in the water. The numbers are easy to read and show both freezing and boiling points. This auto repair tool can be used on a hot or cold radiator in both summer and winter months.
