After using the tractor in winter, be sure to promptly release cold water to prevent freezing of the body. If once you forget to put cooling water and freeze the body, you can use the following measures to perform “smart†treatment:
First, find the crack
1, in the lower part of the engine on the charcoal, slowly bake, open the water tank at the same time, inject warm water into the water tank, do not inject water, the water temperature can be gradually increased, up and down at the same time, until the ice melts completely, from the drain valve Outflow, then close the valve, fill with hot water, wipe the external dirt, find the crack site.
2. The cylinder head and the body are generally protected against freezing. Once the body is subjected to freezing, it will swell out the freezing plug to protect the body. Therefore, when the freezing is not serious, the machine will not be frozen, even if the freezing occurs. Phenomenon often occurs only in weak places, and after the occurrence of cracking, the pressure in other parts will be greatly reduced, and generally it will not be frozen. Therefore, once the body is frozen, it can generally 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, the treatment measures
1. After finding a crack, it should be repaired, glued, or iron plated according to the situation.
2. If the water tank radiator core leaks water 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.
