## Questions & Answers

**Q: what pump can i use with it ? can you give me the picture of the pump , thank you**
A: Try ones like this: Hopkins 10803 FloTool Transfer Pump. Takes 2 hands, but otherwise cheap and effective. Comes with a hose that connects directly without fittings.

**Q: What is the difference between the diesel and gasoline combustion gas tester fluid?**
A: Did not find that particular brand to work very well for diesel. Have used other brands which are combustion chamber leak detectors which work for both gas and diesel. The difference between a gas and diesel detector would be in the chemical formulation.

**Q: I don't have a radiator cap on my radiator So will it work on my overflow? Or what would you recommend**
A: Your  car has a degas bottle. Yeah it will work on that

**Q: Can it detect co2 in coolant? What is the average for success by testing?**
A: Yes, it tests for carbon dioxide and carbon monoxide in your coolant.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Great product
*by T***  on April 29, 2025*

Works great!

### ⭐⭐⭐⭐⭐ Works like it is supposed to.
*by A***G on July 21, 2010*

Used this to confirm what was pretty certain, a head gasket leak. Sure takes the guesswork and time out of detecting head gasket leaks. I was already 95% certain one or both head gaskets were leaking using cylinder compression and leakdown tests and radiator pressure test. I like the ability to shutdown a cylinder bank and test for a leaking head gasket on one head or the other. Caution, if you do this, you will most certainly trip computer codes and the engine service light on the dash. You need to be aware that you have to check that your code reader (if you have one) will reset the engine service light. Not all will. Many will clear codes but not reset engine service light so you may have to got to a shop to have light reset. Some car models can be manually reset or there is some trick to reset.One of the other anecdotal aspects of this test is that you can tell which cylinder bank is leaking faster or slower. The color change for my testing was gradual, ie it went from blue to green to yellow. This shows that the color change is relatively proportional to the amount and rate of leakage. The color change for the right bank was pretty quick and the color change for the left bank took several minutes. I ran this several times on both a hot and cold engine. The results were generally reproducible.

### ⭐⭐⭐⭐⭐ Easy test for busted head gasket
*by A***E on December 16, 2024*

This kit is super easy to use and I prefer this style as I already have a hand vacuum. I use the same one as for brake bleeding. This as opposed to the other kits that have a built in bulb but that's a spot where it can break and render the kit useless.Its super easy instructions to follow and can give you a look to see if exhaust gases are present or not in the coolant knowimg if there is head gasket integrity issues.
