The climate gets colder in winter, to prevent the tractor body from freezing, you can add antifreeze to the engine cooling system.
The common tractor antifreeze in the market mainly includes:; Ethanol, glycerol - ethanol, glycerol, ethylene glycol, etc. These antifreeze solutions have different freezing points due to different preparation ratios and compositions. The freezing point of commonly used antifreeze should be at least 10 ℃ lower than the local minimum temperature to prevent the temperature from falling below the freezing point of the antifreeze and causing it to fail. When using antifreeze, pay attention to the following points:
Before adding antifreeze, the scale in the tractor cooling system should be removed first, and residual water should be drained at once to prevent water from diluting the antifreeze and reducing its freezing point.
When adding antifreeze, it can only be added to within 95% of the cooling system capacity. Antifreeze liquids have moisture absorption properties, and the container lid should be sealed in a timely manner after use.
Ethanol and ethylene glycol both have certain toxicity and should not come into contact with the skin surface, nor should they be inhaled by mouth. Ethylene glycol is an organic solvent. When adding, do not drip or sprinkle on the surface of the body to prevent paint from peeling off and rusting. Ethylene glycol and glycerol will reduce their volume due to volatilization. Water should be added in a timely manner. After leakage, antifreeze of the same type, model, and pour point should be added.
Ethanol and glycerol - The alcohol contained in ethanol antifreeze is volatile and flammable, so attention should be paid to fire prevention. If the alcohol content decreases due to volatilization, it can be supplemented by mixing 80% ethanol with 20% water.
Various types, models, and pour points of antifreeze should not be mixed or mixed.
