## Description

Thexton THE100 Anti-Freeze Tester

Review: Did not work at all for me. Shows no freeze protection straight from new bottle. - Did not work at all for me. Shows no freeze protection straight from new bottle.
Review: Good for Propylene Glycol coolant - If you are using Propylene Glycol coolant such as Sierra, you'll discover that coolant testers for it aren't readily available. An auto parts store clerk tried to tell me that the normal testers would work for Sierra, but that isn't true. So off to desertcart to get the right thing. After I got this tester I tested with both kinds of tester and the reported difference was over 20 degrees. It's nice to be sure of the coolant protection level.

### ⭐⭐⭐⭐ Works just great!
*by E***S on March 28, 2011*

I bought this tester because I use propylene glycol coolant in my vehicles, and a 'standard' antifreeze tester won't test it properly. I have little kids who like to help me work on my vehicles, and I'd just rather have the lower-toxicity coolant around. This tester is cheap, simple, compact, and works well. Testing a fresh 50/50 mix it indicates essentially the same freeze protection level as what the antifreeze label suggests. I gave it 4 stars instead of 5 simply because I could stand to have a longer tube to reach far enough down into my coolant expansion tank on my Subaru without having to try to cram part of my hand into it.
