How to choose antifreeze

Staff from the following aspects should be: 1. Selected according to the ambient temperature the freezing point of antifreeze. The freezing point of antifreeze is one of the most important indicators of antifreeze is antifreeze can freeze an important condition. Under normal circumstances the freezing point of antifreeze should be chosen lower than the local minimum ambient temperature of about 10 ~ 15 ℃, such as a local minimum ambient temperature of 30 ~ C, the freezing point of antifreeze should be selected in a 45 ℃ below. If you want to select glycol liquor to be modulated, can be prepared at a concentration of 59% ethylene glycol, the freezing point at this time the solution is a 50 ~ C, the density of 1.0786g/cm. 2. Selected according to different requirements of the vehicle antifreeze. Into the vehicle under normal circumstances and domestic joint ventures VI production of high, mid-range vehicle antifreeze should be used permanently, the use of a period of 2 to 3 years, and the remaining ordinary vehicles can use the type of direct antifreeze, summer can be replaced by demineralized water . 3. According to the number of vehicles and the concentration of selection antifreeze. More and the relative concentration of the vehicle units and departments, you can use the antifreeze small package liquor, which liquor stable antifreeze, the use of small package for easy transport and storage, while at the same according to different environments and different work conditions flexible modulation required to achieve savings and practical purposes. Vehicles less than or scattered cases, you can directly use the type of antifreeze used. 4. Should generally be used with good anti-rust, corrosion and cleaning ability of antifreeze. Antifreeze is the most important anti-corrosion, so better to use the brand-name products, these products have preservatives added, corrosion inhibitor, scale inhibitor and cleaning agent, product quality is guaranteed. 5. Catheter choice and match the rubber seal of antifreeze, antifreeze should not rubber seal swelling and erosion catheter side effects. Use the proper use of antifreeze antifreeze should note the following questions: 1. Antifreeze before filling the engine cooling system must conduct a careful cleaning. This is because the antifreeze in detergents and cleaning agents are added before using the engine cooling system if not careful cleaning,[link widoczny dla zalogowanych], but directly into the antifreeze, the engine cooling system, any original scale off after contact with antifreeze, so that antifreeze change cloud, thickens, and even color, taste, and in severe congestion pipes, watercourses, or settle in the tank bottom elbow joints. Caused by improper cooling, antifreeze is not circulating, causing the engine temperature is too high. To prevent the occurrence of these phenomena should be in the antifreeze before filling, using 10% caustic soda solution immersion tank lh, then the fluid drained, and then repeatedly washed with demineralized water 2 or 3 times to remove the engine cooling system of the Central Plains accumulation the scale, after flushing to raise new antifreeze. 2. Antifreeze before filling the engine cooling system to check whether the leakage, if any, should be immediately removed in order to use anti-slurry. 3. Ban on direct liquor filling antifreeze. Some drivers and repair workers learn too that the antifreeze, ethylene glycol concentration the bigger the better, and directly raise liquor antifreeze, antifreeze do so not only can not meet the requirements of the freezing point, but there will be some unexpected phenomena such as antifreeze bad,[link widoczny dla zalogowanych], concentration, density, low viscosity, resulting in higher engine temperatures undesirable phenomenon, so be sure to use antifreeze, according to the requirements of the mother liquor prepared to prohibit the direct use. 4. Do not normal as abnormal. Antifreeze has a high boiling point, heat capacity, small evaporation losses, the cooling efficiency. Boiling point of water under environmental conditions in the 760mmHg 100 ℃, the boiling point of ethylene glycol-based antifreeze can have more than 110,[link widoczny dla zalogowanych], so filling the vehicle antifreeze 1 than the soft cooling engine coolant water temperature should be higher than about 10, which is a normal phenomenon. It should be noted that J antifreeze, the temperature while high, but not easy \years, so that there is continuity of J. In order to reduce waste, antifreeze, do not arbitrarily change after i added, however, the course should be> antifreeze checked regularly scheduled items. For example, each combination of seasonal maintenance check on the coolant , j inspection should include the freezing point and density, but also) the use of antifreeze in the visual inspection, and if; current density, antifreeze thickens, freezing up,[link widoczny dla zalogowanych], l and antifreeze change corrosion, deterioration, taste, foam is {should be replaced. 6. antifreeze from different manufacturers can not be mixed one to use, otherwise easily lead to the engine, water tank l eclipse other serious consequences. 7. modern car engines typically put no switch, antifreeze solution is found in the use of the lack of water or when the ban j different types of antifreeze, the engine in order to avoid freezing in winter. 200 412.
