The tester has the same working principle and the same efficiency as expensive testers and its amount is affordable thanks to the innovative method of production.

One set contains An universal adapter A bayonet adapter (diameter - 40, 47 i 55 mm) 2x reactive liquid RELD with a capacity of 8.5oz (together 17oz) Instruction manual with steps to perform the test. In case of a damaged gasket under the cylinder head or the cylinder head itself, a part of the exhaust gas, among other things contains the CO2, which enters the cooling system. The operating principle of the device is based on measuring the CO2 content. With an increased content of CO2, the liquid reacts with the gas and changes colour. The whole process takes only 5 minutes. Our tester offers almost 100% safety if the cylinder gasket isn't broken. Reaction liquid is Blue If after completing all the steps described in the instructions for use, the liquid has not changed its color and is still blue, it means that your gasket under the head and the head are in good working order. Yellow or Green If after all of the steps in the instruction manual, the liquid has changed color from blue to yellow or green, it means that the seal under the head or the head is damaged. Review: Works as advertised - Had adapter to fit radiator fill cap and quickly verified I had a blown head gasket. :-( Review: Works as stated - Used this immediately on a car we had just purchased. We suspected it had a head gasket leak but there was no true indication other than overheating. Cooling fan was also out so which one was the problem? This kit showed it as head gasket. Pulled the head and sure enough it was a blown head gasket probably caused by fan being out. Saved a lot of troubleshooting time. Completely satisfied money well spent! ## Features - The original head gasket tester kit of the reputable brand “RELD”. - Our combustion leak test kit ensures effectiveness of almost 100%. - Fast and convenient.

We suspected it had a head gasket leak but there was no true indication other than overheating. Cooling fan was also out so which one was the problem? This kit showed it as head gasket. Pulled the head and sure enough it was a blown head gasket probably caused by fan being out. Saved a lot of troubleshooting time. Completely satisfied money well spent! ### ⭐⭐⭐⭐ Tool arrived exactly as advertised. Could use some better instructions. *by C***W on February 24, 2026* This was the first time I've used a tester like this. The components arrived and were as advertised. I've run one test and during that test the coolant pushed into the text fluid chamber but I think I got a reliable result. The components are of decent quality. I felt like there could have been better instructions, especially with some tips on what to do if your coolant is about to breach the test fluid chamber. Overall I would recommend this product. ## Frequently Bought Together - RELD Professional Head Gasket Tester Combustion Leak Test Kit Detector CO2 with Box and 17oz CO2 Reaction Liquid - RELD Head Gasket Tester Kit Combustion Leak Detector for 50 Tests --- ## 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.com.kw/products/482834771-reld-professional-head-gasket-tester-combustion-leak-test-kit-detector](https://www.desertcart.com.kw/products/482834771-reld-professional-head-gasket-tester-combustion-leak-test-kit-detector) --- *Product available on Desertcart Kuwait* *Store origin: KW* *Last updated: 2026-05-13*
