Add antifreeze truck? Van antifreeze how to change
Many everyone think automobile antifreeze can only 'freeze' role, in fact in addition to prevent frostbite, it also take on the role of engine cooling fluid '. Truck can add antifreeze has many. Then add antifreeze and everybody about the truck? Van antifreeze how to change? Van how antifreeze 1, according to the environment temperature conditions, choose the freezing point of antifreeze. The freezing point of antifreeze is one of the most important indicator of antifreeze, is the important condition of antifreeze can prevent frostbite. Usually the freezing point of antifreeze should choose the lowest temperature in winter - the condition of local environment Around 10 ℃ to 15 ℃, such as local minimum temperature of - 30 ℃, then the freezing point of antifreeze should choose in - Below 45 ℃. If you want to choose glycol mother liquor modulation glycol concentration of 59% can be produced, freezing point to - 50 ℃, its density is 1. 0786 mg/cubic centimeters of antifreeze. 2, in accordance with the requirements of vehicle different choice of antifreeze. Usually imported cars, domestic introduced production vehicles and vehicle should choose a permanent antifreeze (middle and high class 2 ~ 3 years) , ordinary vehicles can be used directly with antifreeze, softened water can be used in summer. 3, according to the number of vehicles and choose antifreeze concentration. Vehicles and relatively concentrated more units and departments, can use small package of antifreeze mother liquor, stable performance, the antifreeze mother liquor with small package, easy to transport and storage, and also can be used according to different environment conditions and different work requirements for flexible modulation achieve the goal of economical and practical. Under the condition of vehicles or less dispersion, use can use directly with antifreeze. 4, generally should choose antifreeze with rust and corrosion and scale removal ability. Is the most important of antifreeze rust protection. So the appropriate chooses brand-name products, these products to add preservatives, corrosion inhibitor, scale inhibitor and detergent, product quality is guaranteed. 5, choose match the rubber catheter antifreeze. Antifreeze cope with rubber catheter without side effects such as swelling and erosion etc. How to replace 1 van antifreeze, check: before completely replace the antifreeze, to do a comprehensive inspection, look at all the trace of the pipeline is wrong, if there is a crack, the key is to check the five-way pipe, bottom bracket because there are five named connect the parts of the interface, antifreeze is after through the bottom bracket, are assigned to different part of the role of car. If there is a leak phenomenon of antifreeze, this part should be replaced according to the situation or to fixed interface. 2, water: will the old fangdongye, clean with clear water after the liquid channel. Will join the antifreeze added water tank, and then into the pot into the water, making water continuously flows through the engine cooling system, and then the car idle 3 to 5 minutes, let the water cycle. Began to flow of water from the tank is a little light pink, continue to inject water, until out of the water is clean. Pay attention to don't forget to warm wind pipe down, put the water heater tank clean. 3, a new solution: water for about 1 hour later, the new antifreeze by tank ( The radiator) Conduit to join, this is the way to make antifreeze fast into the tank. Then to add another bucket of antifreeze antifreeze cans, added to the antifreeze cans full of fast, in 10 minutes or so, at this time due to rule out the part of the air cooling system, liquid level, then add antifreeze, filling liquid storage tank at the highest mark 'MAXT'. More about 'how van antifreeze? Van antifreeze how to replace the 'all content, hope useful for everyone.
