A method according to the invention makes it possible to make a check of the correct installation and operation of piston cooling nozzles ( 10 ) in a cold text prior to the final assembly of the engine by applying compressed air to each piston cooling nozzle ( 10 ) and directing the jet of compressed air emitted by the piston cooling nozzle ( 10 ) to be checked toward a surface pressure sensor ( 24 ). This makes it possible to record the position of the compressed air jet generated by the piston cooling nozzle ( 10 ) and preferably also the geometry of the jet. It is thereupon possible to draw conclusions concerning the proper operation and installation of the respectively checked piston cooling nozzle ( 10 ).
