We consider non-motorized stand for accelerated thermal cycling test the strength of the cylinder heads of automobile and tractor engines. To measure the temperature at the bottom of the cylinder head seventeen thermocouples were installed. For numerical calculations of the mathematical model, which allows you to define the temperature in the jumper between the valves with the known values of the mean effective pressure and of rotation of the crankshaft. It is shown that these models can be applied in the study of the cylinder head of any engine. The research for tractor diesel engine cylinder heads have shown that the temperature field in the bottom of the testing of engineless stand and the engine are the same. Acceleration cylinder head fracture occurs by increasing tightening force and studs head temperature rise in the center of the bottom of the cylinder head. The acceleration factor on running around 80.
