Important: When using the CO² leakage tester, always ensure that no coolant is drawn in. A diesel engine operates under light load with high excess air and the combustion gas contains a high proportion of unconsumed air. Therefore, place the diesel engine under as high load as possible by means of a test drive or repeatedly revving prior to performing a CO² leakage test. Organic and inorganic salts dissolved in distilled water. The total proportion of these non-toxic ingredients is only 0.03 %. Classification according to Directives 67/548/EEC and 1999/45/EC, this test fluid is classified as "non-harmful".

Application area

After the engine has overheated

When there is a suspected leak if a pressure test (1 bar) does not produce a conclusive result

When there is a suspected hairline crack in the cylinder head and engine block or faulty cylinder head gasket

Instructions

Insert the CO² leakage tester into the cooler or expansion tank opening and by pushing the suction ball inspect the air buffer of the cooling system for increased CO² content (= combustion gas). In the middle chamber of the CO² leakage tester, a change in colour of the blue liquid to "green" and then to more of a "yellow" indicates a leak between the combustion chamber and cooling system.
