Hengding automobile hub unit indicates "not raising car repair", car maintenance should be like people, like health and beauty, received considerable attention.
An adverse reaction: a drip under the car pool of strange liquid, and the liquid level in the coolant down
Causes the disease: Causes drip is usually due to the coolant tank and engine connection between the hose for cracks.
Green maintenance: the quality deterioration of the cooling liquid rust fall, not only easily lead radiators, piping, hoses and other damage of the components, and that the cooling fluid is the main component is ethylene glycol, drip to the ground can also cause environmental and air contamination. It is difficult to visually determine whether the deterioration of the coolant, the coolant should be changed regularly so. General recommendations vehicles traveling 40,000 km or every two years, to be replaced with new coolant, in addition, the cooling fan belt must be replaced every two years.
Second, the adverse reactions: engine misfire
Disease causes: engine start by pushing the battery current spark plug ignition completed, and thus, start the system fails, it may be due to the battery caused by rust or leaking batteries.
Green Care: To view the battery every two months, the battery fluid is sufficient. If insufficient, distilled water was added to the appropriate height. Currently most used car maintenance-free battery, you can not arbitrarily add water. In addition, every year, check the battery positive and negative termination point without rust or dirty phenomenon. If so, should be promptly cleaned to the 4S shop to keep the circuit open. Battery repair, battery scrap can delay time, reduce waste of resources and environmental pollution caused by waste batteries.
Third, the adverse reactions: engine exhaust noise increases, excessive exhaust emissions
Cause condition: Engine exhaust oxidation occurs at high temperature, is likely to cause leakage of the exhaust system. Green Maintenance: Check the exhaust system piping, interfaces (especially muffler, etc.) is being exhaust corrosion, the interface pads have been washed out. If you find an exhaust system leaks, leaks should be repaired or replaced parts. Inspected once a year not only can guarantee the normal operation of the exhaust system, and more important to reduce the emission of harmful substances in the environment.
Fourth, the adverse reactions: increasing vehicle fuel consumption
Disease causes: increased fuel consumption for many reasons, the most common and easy to be overlooked is our tire pressure checks. Insufficient tire pressure will not only lead to increased resistance to the vehicle, resulting in increased fuel consumption, but also affect tire life.
Green Care: Bring your own tire pressure gauge, check the tire pressure regularly. Remember do not forget to check the spare tire, so urgent need to replace the tire only to find the spare tire has no gas. Temperature is high tire pressure is higher than usual, so in cold weather or shade more accurate measurement of tire pressure. Often traveling 10,000 kilometers per tire to be reversed, to avoid wear around that much difference. If you need to replace the badly worn tires, it is best for two or four together, texture same tires front and rear cross replaced. In addition, the line pattern of the tire can help to save fuel.
Fifth, adverse reactions: decreased engine performance, fuel consumption increases, nozzle clogging
Condition Cause: This is probably due to a long period without changing the oil, oil filter, air filter and oil filter cause fuel combustion is not sufficient, the engine and other problems caused by increased carbon.
Green Care: It is recommended engine oil, oil filter every driving about 5,000 km to be replaced once, air filter and oil filter each traveling 10,000 km need to be replaced, otherwise the air, fuel and oil impurities can cause parts oil wear and clogging, thus affecting the normal operation of the engine.
Six, adverse reactions: Pump perishable
Disease causes: the irrational behavior when refueling may cause pump damage.
Green Care: Try not to other fuel warning lights come on again, otherwise it will shorten the life of the pump, or too little of the oil are likely to burn out of fuel pump. If you often travel in urban areas and more convenient refueling, you do not have time to fill, as this may cause the oil float and sensor failure, fuel gauge distortion and increased fuel consumption, recommendations generally do not take emptying refueling.
Seven, adverse reactions: failed vehicle emissions
Cause condition: three-way catalyst of the catalyst and carbon monoxide in the exhaust gas can convert hydrocarbons to carbon dioxide and water vapor, the catalyst failure, it will exceed the standard exhaust.
Green Care: Wheel hub unit Hengding catalytic purifier to understand the normal service life of 100,000 kilometers or more, but it will destroy the activity of the catalyst lead to failure, therefore, can not use leaded gasoline additives and cleaning agents. But in Guangzhou, after 2007 on the licensing of vehicles has been installed OBD (full name "Car Exhaust diagnostic system"), if there is excessive exhaust, the car will automatically alarm, or even interrupt the engine's work.
Eight, adverse reactions: the replacement of three filters, retardation and acceleration engines are still the phenomenon of poor, black smoke
Condition causes: the fuel system problems, such as nozzles, valves coke.
Green Maintenance: Automotive each traveling 10,000 to 15,000 kilometers cleaning and maintenance is required once the fuel system, the use of water removal in fuel system cleaning rust protection agent to remove gum and carbon deposits inside the system, to prevent corrosion, avoid and stop sealing parts and tank leakage, but also completely replace the old coolant.
Nine, adverse reactions: clean the fuel system and three filters, but the engine was underpowered, exhaust black smoke, fuel consumption is large
Condition Reason: probably dirty air filter prevents air circulation, so that power reduction, fuel consumption increases.
Green maintenance: the role of the air purifying filter the air entering the cylinder, dirty air may cause engine performance failure. Therefore, each driving 1000-2000 km is necessary to check the air filter and the lower end of the hose for dirt or water, if there is, we should be timely maintenance. While traveling 10,000 km or 1 year later to replace the air filter.
Ten, adverse reactions: Battery becomes unstable
Condition Cause: abnormal electrolyte changes will affect battery performance and reliability.
Green Care: summer driving, the battery will overcharge phenomenon occurs, the electrolyte evaporates quickly, easily damaged plates. Therefore, the need to frequently check the battery fluid level and specific gravity of electrolyte (electrolyte specific gravity and should be smaller compared to the winter), often filling distilled water to the battery; winter to avoid the battery is fully discharged, and note that the electrolyte is frozen. Cherish your battery, a button battery can contaminate large 600,000 liters of water, which is equivalent to a person's life, the total amount of drinking water; 1 5 batteries can make one square meter of soil never produced.
