Coolant leaks are among the most common causes of engine overheating, and tracing their source without the right equipment means guesswork and wasted time. The Sealey VS006 Cooling System Pressure Test Kit gives you a systematic, 16-piece solution for locating leaks from the head gasket, header tank, radiator and heater cores, water pump, plugs, hoses, and housings across a wide range of vehicle makes. The updated kit now includes two new caps suitable for newer Ford and Vauxhall/Opel vehicles, making it one of the most broadly compatible options in the range. Aluminium radiator header tank caps are colour-coded for ease of use and fitted with quick release fittings. The heavy-duty pump unit features smooth action and a large, easy-to-read scale, while the long hose allows comfortable use of the gauge at a distance. The quick release is fitted with a pressure release valve for safe operation. A thermometer is included, and the complete set is supplied in a rugged storage case. Compatib
