Now more and more people have cars, but people rarely understand the car, many car owners in daily fear with the car suddenly go wrong, but he is unable to solve. However, automobiles and others, are sick before there will be "uncomfortable" performance, but many of us ignore the car "uncomfortable" Today I will summarize 7:00 vehicle malfunction or a sign of impending failure.

1, abnormal noise burst

Automotive abnormal sound is car trouble "alarm", but for people without any vehicle maintenance base, it is difficult to judge what the car noise is normal, what is not normal, but most people can feel it sounds sudden . When there is a sudden some of the past no sound, it shows what the car has changed or been damaged, repair should go as soon as possible.

2, increased fuel consumption

If you run a car in good condition, fuel consumption is generally more stable, no major fluctuations. But if the sudden increase in fuel consumption over a period of time, we must consider whether or not there because the car broke down. We must first rule out factors driving and road factors causing short-term increase in fuel consumption, if the driving and road conditions do not change, it is likely to be a problem in the car itself. Or the engine control system is not working properly, or system component failures with increased running resistance, resulting in increased fuel consumption.

3, oil spills

The problem is obvious, if the vehicle is parked on the ground for a long time have a pool of oil, then the car is definitely a problem. But note that the air conditioning during the summer, will be dripping under the car, grease and water stains to separate area. In addition to watching the ground long after the park, it should open the hood regularly check the condition of the inside of the engine compartment, but if you do not care about the dust, oil stains the same place indicating the presence engine oil leak. And these things spill, discovered the sooner, the smaller the engine damage.

4, exhaust color is not normal

When the engine is working properly, exhaust smoke should be obvious, but in winter temperatures cold, white smoke will be hot as a boiler to normal, if the exhaust is the other colors, black or blue, or in the winter there is not white tail, indicating that the engine has incomplete combustion, burning oil, coolant fleeing and so on, and are generally more serious and require immediate repair.

5, engine overheating

The engine has a normal operating temperature, the temperature is generally used to represent the engine coolant temperature, is often said water temperature. Usually the normal engine operation, the temperature can be maintained between about 90-105 degrees, but there is not much fluctuation maintain a relatively stable value. If the water temperature is too high, certainly it is a variety of problems, even if the car is not water table, there will be a high-temperature warning light, note the following like.

6, unpleasant smell

Here does not mean the new car smell when similar interior decoration of taste, but some of the pills only to discover, gasoline. Description appears gasoline oil leaks or evaporation canister has failed, and the cause of pills only to discover more, short circuit, burned the clutch, put the handbrake ...... forget when we must stop the pills only to discover, can not continue to open .

7, uneven tire wear

Local car tires are the only contact with the ground, but in order to achieve all aspects of performance, not vertically mounted on a vehicle wheel, it has a variety of various positional parameters. Once these parameters have erred, there will be no normal tire, uneven wear, which always felt that if a certain part of the tire or tire wear particularly fast, then it must be suspension problems.
