A tool system for replacing a glow plug ( 31 ) of a diesel engine includes a plurality of tools ( 55 ), by means of which a defective glow plug ( 31 ), which is screwed tightly into an internal thread ( 33 ) of a mounting hole ( 32 ) of a cylinder head ( 30 ) of the diesel engine, can be removed from the mounting hole ( 32 ), the glow plug ( 31 ) being arranged in a radially expanded, cylindrical depression ( 34 ) of the mounting hole ( 32 ) of the cylinder head ( 30 ). To make it possible to accurately align the individual tools ( 55 ) necessary for replacing the glow plug ( 31 ) with the central longitudinal axis of the mounting hole ( 32 ), a clamping sleeve ( 2 ) is provided, which can be inserted into the depression ( 34 ) and into which a centering sleeve ( 1, 20 ) can be pushed to concentrically align the individual tools ( 55, 65, 75, 85, 95 ). The clamping sleeve ( 2 ) can be pressed into the depression ( 34 ) to hold the centering sleeve ( 1, 20 ) in a fixed and clamping manner.
