Designed for quick, nearly 100% accurate testing across a wide range of vehicles, it empowers professionals and DIYers alike to diagnose head gasket integrity without costly mechanic visits. ## Description The RELD tester is designed to detect damage to the cylinder head and gasket of combustion, liquid-cooled engines (petrol, diesel, LPG). The tester has the same working principle and the same efficiency as expensive testers and its price is affordable thanks to the innovative method of production.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.One set contains:An universal adapterA 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.We attach a universal adapter to our RELD tester which has a wide range of measurements (25-55 mm). Among other things, it can be controlled: cars, trucks, road tractors, excavators, motorcycles, forklifts.RELD reagent liquid is blue.If after carrying out all the steps described in the instructions for use the liquid has not changed colour and remains blue - it means that the gasket under the cylinder head and the cylinder head are in perfect condition.RELD reagent liquid is yellow or green.If the liquid has changed colour from blue to yellow or green - it means that the gasket under the cylinder head or the cylinder head is damaged.
