After the winter agricultural machinery is used, cold water must be released in time to prevent freezing of the body. If you forget to let the cooling water and freeze the body, you can use the following measures: First, find the crack 1. Put charcoal in the lower part of the engine and bake it slowly. Do not use it for baking in the fire. At the same time, open the mouth of the box and inject warm water into the box. Do not inject boiling water. The temperature of the water can gradually increase. In this way, it is performed up and down simultaneously until the ice melts completely and flows out of the discharge valve. Then close the valve, fill with hot water, wipe the external dirt, find the frozen cracks, to be repaired. 2. The cylinder head and the body are generally protected against freezing. Once the body is subjected to freezing, it will swell the antifreeze plug to protect the body. Therefore, when the freezing is not serious, the machine will generally not be frozen. Even if the cracking phenomenon occurs, it will only occur in weak places. Once the cracking phenomenon occurs, the pressure in other parts will be greatly reduced, and generally will not be Cracked. Therefore, once the body is frozen, it can only be frozen. 3, the machine is frozen, cracks can not be on the outside, after the external inspection, you can loosen the oil sump drain bolts, if water seepage, it is necessary to let go of the oil, remove the oil pan, carefully find the leak Parts. Second, remedial measures 1, first find the crack, should be repaired according to the situation, stick repair or repair with iron plate. 2. If the radiator heat sink leaks and the quantity is small, both ends of the water pipe core can be blocked and used. If there is more crack, use it after welding. Therefore, the antifreeze oil should be replaced in time in winter, and the diesel oil should be high oil. If there is no warm storage when it is stopped, all the water in the tank will be released when the water temperature drops to about 30 degrees Celsius.
