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 ### ⭐⭐⭐⭐⭐ Seems to work well. *by on Reviewed in Canada 16 January 2022* For a gasoline engine cooling system. May work with diesel, but I doubt it, since I believe that diesels put out less hydrocarbons. I think this company makes a diesel version of this kit. Make sure the cooling system is full, install this glass globe on the radiator opening/surge tank opening, fill with the magic mystery fluid, and connect it to a vacuum source. (Either to engine vacuum, or use a mity-vac style vacuum gun.) If there is a crack around the combustion cylinder, or a faulty head gasket, then you should see the magic mystery fluid change colour. This is just another quick way to check for combustion leaks. Other methods may be performing a cooling system pressure test, and checking for coolant on top of the pistons. Or, install a pressure test gauge on the cooling system, keep it at zero PSI, and run the engine. A bad head gasket may push pressure into the cooling system, and make the pressure gauge needle jump up. Or, perform a cylinder compression test. ### ⭐⭐⭐⭐⭐ Great product *by on Reviewed in the United States 19 March 2026* Bought this to test my head gasket. Easy to use. Easy to follow instructions. Text is clear and works just as it’s supposed to. Figured out why my car was overheating. Blown head gasket. ### ⭐⭐⭐⭐⭐ Encuentra fallas de junta de cabeza *by on Reviewed in Mexico 15 July 2019* Funciona bien , hay que tener cuidado de no contaminar la muestra con anticongelante. ## Frequently Bought Together - Lisle 75500 Combustion Leak Detector - Stant Cooling System Tester, Metallic --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.tn/products/281724455-lisle-75500-combustion-leak-detector-automotive-diagnostic-tool](https://www.desertcart.tn/products/281724455-lisle-75500-combustion-leak-detector-automotive-diagnostic-tool) --- *Product available on Desertcart Tunisia* *Store origin: TN* *Last updated: 2026-07-21*
