Many car owners find that the car is a bit wrong and like to open the engine cover (also called the engine compartment cover), “check” some, but in fact many car owners do not understand the structure of the engine compartment, some car owners do not even open it, When it finally opened, I looked at it a little bit at a loss. The following will tell the majority of car owners, after opening the engine cover, what tests can you do?
The premise is that your engine compartment is not fully protected by the cover, as shown below
Owners who are not too troublesome can also remove various protective shells to look inside the engine compartment.
- Check the coolant
The role of the coolant is to help the engine dissipate heat in summer and prevent the power system from freezing in winter, so many people also call it antifreeze. Another feature of the coolant is anti-corrosion. It is not suitable to produce dirt and corrode pipes during the circulation and heat dissipation.
Although the coolant is generally replaced every 2 years or 40,000 kilometers, it can also be determined according to the actual situation.
When the coolant is between the scale marks MAX and MIN, there is no need to add extra; when the color of the coolant is abnormal and there is precipitation, it is very likely to need to be replaced, and it is recommended to replace it with a professional auto repair shop.
- Check glass water, also called wiper
The role of glass water is very simple, it is used to clean the windshield. Regardless of the season, if the owner has a long car wash cycle, he will often use glass water to clean the windshield. After a long time, he may forget to add it, so after opening the engine cover, you can also check the tubular container with blue cover. Most of the water is blue, it is easy to observe the remaining amount. If you find that the remaining amount is not enough, you need to add it in time. It is not recommended to add tap water directly. This is easy to accumulate scale, and the cleaning effect is poor, the lubrication is not enough, and the wiper may also be used during the process. Scraped glass.
Owners can refer to some self-made and effective glass water materials on the Internet, or purchase glass water directly to add.
- See if there is food on the surface of the engine
If there is food, it is very likely that a mouse has patronized it, and the air conditioning filter is polluted by excreta, and then there will be an odor of the air conditioner. After the air conditioner is turned on, the odor will appear, which means that the air conditioner filter needs to be replaced, and even needs to be removed. Foreign body in the air-conditioning pipeline, or mold will seriously affect your health.
- Check whether there is oil sludge on the surface of the engine
Due to oil leakage, dust and gravel are easily adhered to the surface to form oil sludge. The cause of oil leakage in the engine compartment may be the aging of the valve oil seal, the aging of the sealing strip in the engine, or the car manufacturer’s own process is not precise enough As a result, this situation also requires a specific inspection at a professional maintenance store.
- Check the oil
In addition, the above-mentioned inspections should be carried out under cold conditions, and the inspection of engine oil is no exception.
The yellow pull ring is the oil scale, just pull it out hard.
After drawing out, dry the ruler with a clean rag or paper towel, and then insert the ruler back to the original position to re-extract. The red arrow on the far left is the minimum scale, the second red arrow is the maximum scale, and the blue arrow shows the oil Add too much, the normal oil quantity should be between the two red arrows.
- Test or replace the headlight bulb
The rubber cover behind the headlights is opened when the headlights are fogged. If the headlights are fogging, you can remove the rubber cover and blow hot air inside to dry the water vapor, but some models are not suitable because the space in the engine compartment is limited, which is not conducive to removal. Lower the lid. If it is operable, when the original lamp is dim, extinguished, etc., the cover can also be opened directly to replace the bulb.
