## Questions & Answers

**Q: Is it a one time use or you can test multiple cars?**
A: You can run dozens and dozens of tests on different cars. Good for many years of use. Works as it was designed to do.

**Q: Does this work with any type of coolant?**
A: This product works with any ethylenglycol-based coolant. It does not matter if the coolant is an OAT (organic), IAT (inorganic/synthetic) or HOAT (hybrid).

**Q: How accurate is this thing? I just had my coolant replaced and it’s still reading below the recommended temp.**
A: Below is good when it comes to the coolant freezing. 
Is it reading a low temp, or do you mean it's reading higher than what you need for freeze protection?

**Q: Will this work on a semi truck?**
A: As long as the coolant is ethylene glycol based.

### ⭐⭐⭐⭐⭐ Great value
*by D***C on January 16, 2024*

I doubt this is particularly precise but I’d argue high precision not particularly required for testing anti freeze. Is tremendously easy to use and worth having even if you have a shop do the antifreeze replacement work because I found in my case my shop left me tremendously under protected after some radiator work. Rinse it out after use or it won’t last long term.
