Draper Expert Combustion Gas Leak Detector Kit

This Draper Combustion Gas Detector Kit is ideal for determining if CO² is present in a vehicle's cooling system. CO² in the cooling system can indicate a head gasket leak, cracked block or a warped head, etc. Simple to operate by adding blue detector fluid to the tester and placing tester onto the radiator; air is drawn through the liquid which will change colour to yellow if CO² is present. Supplied with detector fluid.
