## Features

- Critical Function: This antifreeze coolant tester measures the freezing point and concentration of coolant, reflecting the current status of the vehicle's cooling system. Based on the measurement results, you can easily judge whether the coolant is still effective or needs to be replenished or replaced
- Accurate Measurement: This tester features °F and °C scales and can provide coolant freezing point readings ranging from -43°C to -12°C (-45°F to 10°F). The dial is laid out reasonably and is combined with a highly transparent shell, allowing you to accurately observe the measurement results
- Reliable Material: This coolant tester is made of PC material, which is highly durable and impact-resistant, ensuring that it will not crack even after long-term use. In addition, the airbag and pipe parts are made of silicone, which is flexible and can be bent repeatedly
- Easy to Operate: First, squeeze the airbag to remove all air. Next, place the tube in the coolant and draw the liquid into the tester. Then, hold the tester vertically and wait a few seconds for the red floating pointer to align with the center line. Finally, observe the pointer and read the data
- Ideal Size: The body dimensions of this antifreeze coolant tester are 3.9 × 1.8 × 0.7 inches. The silicone hose of the tester is 5.31 inches in length and 0.43 inches in diameter. The size makes it convenient to carry and store, but it won't take up too much storage space

### ⭐⭐⭐⭐⭐ Easy way to test coolant effectiveness, easy to use, works as intended
*by M***S on December 30, 2025*

I got this coolant tester to check the coolant freeze point in my old 2001 pickup truck. I bought the truck back in the spring and had no idea whether the former owner actually put the correct coolant mixture in it or if it was too diluted to be safe through the winter. This tester gave me the info I needed and now I'm not worried about my coolant freezing and damaging the engine! This is a simple, bulb-type of tester. The instructions are very simple and clear. First you open the radiator/coolant cap while the car is cool. With the cap off, start the car and let it get up to operating temperature. Next, squeeze the bulb on the tester and draw enough coolant out of the radiator or reservoir to fill the tester up to the "fluid level" line. Hold the tester vertically, using the level line to make sure it's level, then look at the large pointer to get your reading. The front side shows the temperature you can get to before freezing, and the back side shows the boiling point. Mine read -20°F freeze point, which is safely within the safety zone for my area. This simple tool is easy to use, works flawlessly, and gives very valuable information. The peace of mind is absolutely worth the cost.
