This paper presents a model test stand for testing the cooling system with increased coolant temperature. On the model stand, as a result of the research, determined the characteristics of temperature and pressure courses coolant. The study was preceded by the determination of the intensity of the liquid flowing out of the engine block and flowing through the radiator as a function of the opening of the valve throttling the flow of liquid and as a function of speed water pump. An adjustable valve was located in the water outlet duct of the engine. During the test the cooling system was filled with coolant at 90%. After preliminary studies, the degree of filling of the liquid was found to be optimal, because the greater the amount of water in the system observed difficulties in obtaining elevated temperature, whereas at lower amounts of liquid vortex centrifugal pump had problems with the rib. Then, the characteristics of the two ways of controlling the pump capacity were made, ie by throttling the discharge and change in speed. The characteristics indicate that the first way to adjustment of the pump flow rate and thus cooling intensity was less effective, because a small amount of throttling was not affect the change. The second way to adjustment of the liquid flow rate with changes in the speed of the water pump was more efficient, because it was easier to maintain the pressure established in the cooling system.
