North Benz V3 parts thermostat is automatically adjusted according to the change of water flowing through the radiator cooling system of engine water, in the long-term use, the thermostat will sometimes cause engine failure, hot or cold, the power decline, increased fuel consumption, so in driving can do maintenance work, improve the use of economizer life.
North Benz V3 engine accessories after the start of the examination: open the radiator cap, if the radiator cooling horizontal static thermostat, that works properly, otherwise said disorders thermostat, this is because when the water temperature is below 70 degrees, the cylinder contraction in the expansion of the thermostat, the main valve is closed; when the water temperature is higher than 80 when the degree of expansion cylinder expansion, gradually open the main valve, radiator inner circulating water to flow, water temperature is warm; that the thermostat main valve is not tightly closed, the cooling water cycle early.
Check the temperature rise after the engine start working water temperature rise very quickly: when the water temperature table shows 80 degrees after the heating rate slows down, that the thermostat is working properly, on the contrary, if the temperature rises quickly, when the internal pressure reaches a certain level, suddenly boiling water overflow, that the main valve is blocked. When the temperature of the water table shows 70 – 80 degrees, open the radiator cover and the radiator drain switch, with the temperature if feel hot, that the thermostat is normal; if the radiator outlet water temperature is low, and the North Benz V3 parts radiator water chamber water inlet pipe water outflow or less, that the thermostat main valve cannot open.
