I've owned this tester for 5 years but haven't used it since I bought it. When I went to change the
antifreeze on my "fleet" of vehicles I realized the markings don't make much sense without a key.
Luckily I saved the back flap of the packaging and present it here so everybody can see: Measure cold coolant on the white scale, and hot coolant on the green scale. Not terribly intuitive color coding.
The Temperature in 10 degree steps is the Fahrenheit scale, the other is Celsius.
