Many people will think that the engine compartment under the front cover of the car is too complex. The inspection should be done by the 4S shop after-sales or maintenance shop. In fact, we can do this by ourselves as far as the oil inspection is concerned, and mastering the oil state can find the fault symptoms of the car in time. Today's automobile sheet metal parts manufacturers teach you simple automobile engine inspection and maintenance

I. oil inspection

The engine oil can play the role of lubrication, cooling and sealing. Before checking the engine oil, the vehicle shall be parked on a flat road surface, and the vehicle shall be stopped for more than 10 minutes before checking, and the vehicle shall be hot before checking after staying overnight.

Check the oil quantity of the engine oil. First wipe the oil dipstick and insert it back. Only when it is inserted to the end can the oil quantity be accurately measured. Generally, there will be a scale prompt at the end of the dipstick, with upper limit and lower limit respectively, which belong to normal state.

To judge whether the engine oil is deteriorated, a piece of white paper should be used to drop the engine oil on it to observe the cleanliness. If there are metal impurities, dark color and pungent smell, it means that the engine oil needs to be replaced.

II. Brake fluid inspection

Brake fluid, also known as brake oil, provides energy transfer, heat dissipation, corrosion prevention, rust prevention and lubrication for the brake system. In fact, the replacement cycle of brake fluid is relatively long. Usually, it is only necessary to see whether the liquid level is in the normal position (that is, the position between the upper limit and the lower limit).

Under what circumstances does the brake fluid need to be changed?

1. Regular maintenance period

2. Open the brake fluid tank cover and observe the liquid level, which is turbid or milky.

3. The brake force drops and needs to be checked.

III. coolant inspection

The coolant keeps the engine operating at normal temperature. As with brake fluid, the replacement cycle of coolant is relatively long. Usually, only pay attention to the amount of fluid. It should be noted that the hose is not damaged.

In addition, the color of the coolant will also reflect whether it is deteriorated or not. However, different colors of the coolant make it difficult for ordinary vehicles to judge, which requires professional instruments. Therefore, if the water temperature is too high when the vehicle is running under the condition of normal oil volume and pipeline, it is necessary to go to the 4S shop or service shop for inspection.

IV. power steering oil detection

The power steering oil helps to reduce the wear of the steering pump and the steering force of the steering wheel, so if the direction becomes heavier than before, there may be a problem with the power steering oil. However, the electric power steering car, there is no need to test.

Generally, the power steering oil is replaced every 40000 km / 2 years. The maintenance manual also contains detailed instructions. In fact, the detection method is similar to the oil level. Pay attention to the oil level mark on the dipstick. And oil is also to take white paper to color, if there is a blackening situation should be replaced in time.

V. glass water inspection

The inspection of glass water is relatively simple, to ensure that the liquid volume does not exceed the upper limit scale line. If there is less, add it in time, and there is no lower limit. It should be noted that the glass water of the rear window of some models should be filled independently.
