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 ### ⭐⭐⭐⭐⭐ Review *by M***E on March 19, 2026* ### ⭐⭐⭐⭐⭐ Review *by A***G on July 21, 2010* ### ⭐⭐⭐⭐⭐ Review *by C***K on March 30, 2013* ## Frequently Bought Together - Lisle 75500 Combustion Leak Detector - Stant Cooling System Tester, Metallic --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.pl/products/10630549-lisle-75500-combustion-leak-detector](https://www.desertcart.pl/products/10630549-lisle-75500-combustion-leak-detector) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-06*
