【Easy to Use】: To use, simply insert the hose into the coolant reservoir to draw up the coolant until it reaches the marked line on the tester's body. As the temperature of the fluid changes, the dial's pointer will indicate the freezing point, enabling you to quickly check coolant conditions with ease.
