Method for finding leaks in cooling fluid circuits of combustion engines and in particular in the cylinder heads of internal-combustion engines, which method is characterised in that it consists in passing through the circuit of said cooling fluid, after first having closed off all apertures therein, a quantity of soapy water at the engine's normal running temperature and in locating any leaks by the formation of soapy bubbles at these points on the outside of said cylinder head. <IMAGE>
