What to Do When Coolant is Insufficient?
1 Answers
When the engine is cold, directly open the coolant reservoir and top up the coolant to between the upper and lower level marks. Here is some relevant information about coolant: 1. Characteristics of Coolant: Automotive engine coolant is mainly composed of water, ethylene glycol, and additives, with corrosion inhibitors being the primary additive. The main function of additives is to prevent corrosion, while also providing anti-scale and anti-foam effects. Currently, the base fluid for automotive engine coolant is primarily ethylene glycol, and the differences in coolant formulations lie in the use of different corrosion inhibitor systems. Under the premise of using water and ethylene glycol as the base fluids, the key technology in coolant formulation research is the selection and combination of corrosion inhibitors. Typically, coolants are classified into inorganic salt types and organic acid types based on the composition of corrosion inhibitors, with inorganic salt types further divided into phosphate type, amine type, and silicate type. 2. Product Performance: Engine coolant in the coolant reservoir consists of three parts: water, antifreeze, and additives. Depending on the antifreeze component, it can be classified into alcohol type, glycerol type, ethylene glycol type, and other types of coolants. Alcohol-type coolant uses ethanol (commonly known as alcohol) as the antifreeze, which is inexpensive, has good fluidity, and simple preparation process. However, it has a low boiling point, is prone to evaporation loss, has an easily increased freezing point, and is flammable, and is gradually being phased out.
