Agricultural truck winter water three attention
Do not start with the first fire plus cold water to start, the engine temperature rises sharply, the instantaneous temperature of the combustion chamber can reach several hundred degrees Celsius. If cold water is suddenly added to the tank at this time, cracks may easily occur in the body cylinder parts due to rapid cooling, and the piston, connecting rod, etc. may also be deformed. The correct method: Before starting, add 80°C hot water to the tank and warm up the engine. Don't rush to put water after use. The winter temperature is low. After use, the body temperature is high, and the temperature difference from the outside is large. If you just turn off and let go of the cooling water, the cooling rate of the airframe is too fast, and it may cause cracks in the water tank, engine parts, cylinder heads, etc. . The right way: Let the engine run idly for 5-6 minutes. Wait for the body temperature to drop to 50-60°C and let go of the cooling water. Pay attention to the observation of water discharge, and ensure that the net temperature of water discharge is reduced to zero. This requires special attention so as to avoid freezing of cooling water, freezing of water tanks and other components. When the water is drained, the water discharge condition should be carefully observed. If the water flow is not smooth, the drain switch should be opened so that the cooling water can be fully discharged.
