How should I maintain my car? How to maintain the car

In winter, if the chassis is to be maintained, it is necessary to thoroughly clean the chassis and prevent rust. First of all, the chassis should be thoroughly cleaned, if there is too much mud on the chassis, it should be washed with a detergent to remove grease, so that the chassis can reveal its original "true color", so that the anti-rust care can begin. In a professional beauty shop, the car can be lifted onto the lifting frame for chassis cleaning, wiping, and rust prevention.

In the middle of this, it should be noted that after cleaning, you must wait until the moisture on the chassis is dry before you can carry out anti-rust care. When applying care, it is important to maintain an even spray coating to create a uniform anti-rust coating that will last for a long time. After all the work is completed, it will be dried for 5-10 minutes to prevent rust from rust on the chassis. Hope.

For new cars, daily routine inspections are indispensable. In general, the following nine routine tests should be used as a starting point.

Check the condition of the transmission belt, exhaust system, and battery;

change the oil and oil filter;

Check and clean the air filter;

Check the performance of the braking system and the quality and quantity of brake fluid;

Check the quality and quantity of the steering system and booster oil;

Check the dust cover of each ball joint tie rod in the chassis;

Check the condition of the front and rear suspensions;

Check the condition of the tires;

Check the performance of your air conditioning system.

Doing regular maintenance can make the car control smoother, eliminate minor problems in time, and the car will last longer. It is necessary to do some routine check-ups every year. And one of the most important is cleanliness.

How to maintain the car

First, the tire pressure should be sufficient, and the parking space should be "cool."

We should appropriately increase the tire pressure, so as to effectively reduce the degree of tire deformation and slow down the damage to the tire after long-term parking. If you don't want to use the tire pressure recommended by the car manufacturer, the general tire pressure can be reached, all seasons.

2. The battery should be kept in a fully charged state.

The lead-acid battery on the car will have self-discharge even if it is not used, and the self-discharge will reduce the capacity by more than 1% every day and night.

When the capacitance of the battery is less than 70% of the standard capacitance, sulfide will be generated on the surface of the plate inside the battery, which will cause irreversible damage, and the service life of the battery will be greatly shortened, or even scrapped in advance.

Therefore, before the car stops, it is necessary to keep the battery in a fully charged state, turn off all electrical appliances, and remove the negative terminal wiring of the battery, which can reduce the discharge rate of the battery and prolong the service life of the battery. If you don't want to unplug the negative electrode, then it is best to check the battery every two weeks, for example, whether the height of the electrolytic liquid is 10 to 15mm higher than the plate, and if it is not enough, then add distilled water.

The usual maintenance of the car is mainly in the following aspects:

1. Cleaning. The air contains a large amount of dust, sediment and acidic substances, which are not only easy to be adhered to by leaking fuel, but also easy to form a hard insulation layer under high temperature baking, which makes the heat dissipation performance of the parts worse, and is easy to be eroded by the static electricity of the body and erode the paint surface, making it fade prematurely.

1) Clean the air filter.

Dirty air filters can steeply block fresh air from entering the cylinder, resulting in over-concentrated air, incomplete combustion, reduced power, and excessive exhaust air. Modern air filters generally use paper filters, and care should be taken when cleaning: do not wash with water or oil.

2) Clean the oil filter.

The blockage of the oil filter will hinder the flow of lubricating oil, making the engine poorly lubricated, increased wear and tear and even tile burning. For this purpose, it should be cleaned or replaced regularly. Usually it is replaced every 8,000 km, but if the weather is dry, it should be shortened to 5,000 km.

3) Clean the battery.

Modern cars generally use maintenance-free batteries, clean the top of the battery and the battery binding post, in order to avoid short circuit caused by electrolyte or other impurities between the poles and prevent the joint from producing oxides and causing poor contact.

2. Fastening. Due to the vibration, bump, swing and other reasons during the driving of the vehicle, the connection will inevitably be loose and worn. Therefore, it should be tightened in time during daily maintenance.

The daily fastening work of the connector is directly related to driving safety, especially the steering, braking, transmission, etc. of important components, which must not be taken lightly. For example:

1) Tighten the joints of each hose around the engine to prevent oil leakage.

2) Tighten the connectors of each line and electrical equipment to prevent the normal operation of electrical equipment from being affected by open circuits, short circuits, and tie-offs.

3) Check and tighten the main connectors. Such as generator drive belts, steering linkage braking device coupling points, drive trains and tires.

3. Inspection. The height and quality of the fluid should be checked, as the fluid will gradually wear off and oxidize at high temperatures, resulting in a decrease in fluid level and deterioration in performance. Check the liquid level height of the battery with a test tube with a diameter of 5 n 6mm, after the vertical force from the liquid filling port to contact with the filter screen, close the upper end of the test tube with your thumb, lift the tube, and measure the height of the liquid column is the liquid level height of the battery, and the standard should be 10 n 15mm.

4. Supplement. 1) Replenishment of fluids.

If no obvious deterioration of the oil is found during the inspection, it should be found out whether there is leakage, and if so, it should be eliminated, and the same level of oil should be replenished in time.

2) Replacement of fluid.

If the oil deteriorates or exceeds the replacement interval, it should be replaced in time. Usually change the oil every 8000km or half a year; Change the brake fluid every 24,000 kilometers or 2 years; Use to replace the coolant once every 1-2 years; Change the hydraulic oil every year of use or 10,000 kilometers traveled.

There are many aspects of maintenance, mainly the following aspects.

1. Daily maintenance, which mainly refers to paying attention to the condition of the car and doing some cleaning work on time to wash and decontaminate.

2 kilometers of maintenance, this is mainly to go to the relevant professional institutions for maintenance, engine cleaning, air conditioning, brakes and other maintenance.

3. It is the repair of some problems, such as paint repair, tire replacement and some other aspects of maintenance.

Hello can be based on your own situation, if you don't understand, it's best to go to the 4S shop or car repair place maintenance, if you understand the knowledge of the car, then you can find a maintenance car master to ask for consultation, and then you can maintain your car normally through learning.

How to maintain a car in winter? The old driver will teach you a few tips for car winter maintenance.

<> "Is Your Car Maintenance Your Way Right?"

Car care is very particular, many people are like a baby for their own car often do maintenance everywhere, but I never thought that I thought it was a way to maintain the car, it was all wrong!

1. Waxing in a circle.

Many people wax the body in a circle.

Correct approach: In a straight line, the horizontal and vertical lines are alternated, and then the last one is carried out in the direction of rainwater flow, so as to achieve the effect of reducing the concentric circle halo on the surface of the paint.

2. Too much oil.

If there is too much oil, the crankshaft handle and the big end of the connecting rod will be violently agitated when the engine is working, which will not only increase the internal power loss of the engine, but also increase the amount of oil splashed on the cylinder wall, resulting in the failure of burning and draining the oil.

Correct practice: The oil in the engine oil pan should be controlled between the oil dipstick and the lower engraved line.

3. The bolt is too tight.

There are many fasteners connected with bolts and nuts on the car, and they should be guaranteed to have sufficient preload, but they should not be overtightened, on the one hand, the connectors will be permanently deformed under the action of external force; On the other hand, the bolt will be tensile and permanently deformed, and the preload will decrease, and even cause slippage or breakage.

Correct approach: It should be guaranteed to have sufficient preload, but it should not be overtightened.

4. The new battery is not charged.

If the battery is not charged, that is, add "water" to use directly, the capacity of the battery is not high, and the life will be shortened; If you take the front grip to charge it directly, it will also shorten the lifespan.

Correct practice: Usually the initial charging of the battery is after filling the electrolyte, and it can be installed and used by charging it with a small current for about 1 hour.

5. The temperature of the cooling water is too low.

In summer, the weather is hot, and some drivers blindly require the cooling water temperature to be as low as possible in order to prevent the engine temperature from being too high; In order to achieve the purpose of cooling, some drivers simply remove the thermostat, which is not right.

If the temperature of the cooling water is too low, it will worsen fuel combustion, increase fuel consumption, aggravate wear, increase oil viscosity, and reduce engine power.

Correct approach: The temperature of the cooling water is not as low as possible, and should generally be controlled between 80 and 90 degrees Celsius.

<> "How to maintain the car.

First, the fuel tank is closed and cannot be ignored.

When it comes to ensuring that the fuel tank is closed when the vehicle is stopped, you may think that this is done to avoid the volatilization of gasoline, but the most important thing is to prevent the gasoline from spoiling.

Because gasoline is stored for too long, some substances will be lost, and the anti-knock performance of gasoline will be reduced, that is to say, the gasoline of 95 may be destroyed for a period of time, and the engine will be damaged if deflagration occurs when using the car. So, when we are ready to not use the car for a long time, try not to store too much oil in the tank. If you find that the air tightness is very poor, you can use plastic film to block the oil filler and then twist the Qingyuan sealing cover.

Second, the car should be put off before parking for a long time.

Oil engine oil, transmission oil, brake oil, oil filter, fuel filter, air filter" are all have a service life, the car is parked for a long time, the phenomenon of oil oxidation will be very serious.

After the oil is oxidized, first, the lubrication effect will become very poor, and second, some acidic substances will also cause corrosion to the parts. When the engine starts again, dry friction or semi-dry friction will form between the cylinder and the piston, which will accelerate the wear of the parts, and the collapse will cause start-up difficulties. Therefore, it is necessary to drain the oil, and the antifreeze in the cooling system must also be drained.
