How to maintain a car parked for a long time, and how to maintain a car parked for a long time

Due to business trips and other reasons, there are many people who park their cars for a long time, and there are many car lovers who park their original cars for a long time after buying a second car and forget to maintain them, which is very bad for the car.

The hub is not beetle, and the car is the same. Cars that have not been used for a long time have a higher failure rate than cars that are generally in normal use. If the car is parked for more than a week, it will shorten the life of the car to varying degrees.

If the vehicle has been in the garage for too long, it is recommended to go to the repair shop to check the battery, oil, etc. in time when it is reused.

When the vehicle is driving, the engine will charge the battery, if it is not turned on for a long time, the battery has no charging source, but it also has to supply power to electronic equipment such as immobilizers, and there will be a loss of power after a long time, resulting in the vehicle can not be normal. If the battery loses power frequently, the life of the battery will be greatly shortened. For some vehicles with reduced battery storage capacity, parking for more than a week may cause the vehicle to fail to ignite.

Long-term downtime can also lead to accelerated deterioration of engine oil, brake fluid, antifreeze, etc. The oil seal will be more susceptible to aging, because the vehicle is stopped, the contact force around the oil seal is always uneven, until the oil seal is permanently deformed, which is very easy to leak oil. If the parking environment is not good or the tire pressure is too low, it will also cause tire corrosion or wheel rim deformation.

Therefore, after long-term parking, it is recommended to drive the vehicle to the repair shop to check all kinds of oil, and after long-term parking, it is recommended to shorten the maintenance cycle, and the inspection should also include various circuits, beware of rats and other bites of wires, etc. The electronic components are malfunctioning. The electronic components and connectors on automobiles have a common feature, which is to prevent water, moisture and corrosion, otherwise they will cause failure.

For the electronic components or plug-in connectors of a stopped vehicle, the potential for moisture increases dramatically, and the longer the downtime, the higher the probability of failure.

After long-term parking, the tires will deform. After the car is stopped, the weight of the car is borne by the parts of the four tires that touch the ground, resulting in compression and contraction deformation of the contact parts. The longer the car is stopped, the more difficult it is to recover the deformed parts, which changes the weight distribution around the tires, and the rolling radius is uneven, resulting in tire imbalance.

Once the car enters high-speed driving, the body shake will occur, which can accelerate the wear of tires and bring hidden dangers to driving safety.

1. Clean up the vehicle; If you are ready to park your vehicle for a long time, you should clean up all the items in the car, such as lighters, glasses, drink bottles, etc., so as to avoid spontaneous combustion of some flammable and explosive items in the car due to high temperature after the sun is exposed to the vehicle, and the consequences are unimaginable.

2. If the vehicle is parked for more than a few months, it is best to empty the antifreeze, engine oil, etc. If the vehicle has been parked for a long time, you can wait until the car is time to change the oil and antifreeze, and then all of them are empty, and then do not add a new one, and when the vehicle continues to be used, it is not too late to replace it with a new one. This saves some money and prevents oil and antifreeze from deteriorating and affecting vehicle components.

3. When parking for a long time, it is best to use a jack to jack up the vehicle. If the vehicle needs to be parked for several months, then it is better to jack the vehicle up. In this way, the vehicle suspension and shock absorption system can be well protected, pay attention to the position of the jack must be accurate, otherwise it will be equivalent to hurting the car, if you can't get it yourself, then ask a professional to deal with it.

4. Ensure that the fuel tank is airtight, do not expose to the sun, and avoid excessive temperature. For vehicles that need to be parked for a long time, the airtightness of the fuel tank should be ensured, and there should be no oil leakage and oil leakage, and it should be noted that the vehicle should not be exposed to the sun at all times, which will lead to high fuel tank temperature and increase the danger. If there is no fixed parking spot such as a garage, then you can use a sunshade, pay attention to buy some ***, thicker.

5. Drive a mile per week. For long-term parked vehicles, every week should be driven to keep the vehicle running, which is very beneficial to the vehicle, driving dozens of kilometers, so that the various parts of the vehicle can run in and avoid rust or corrosion. It is best to run to the high speed and pull the revs to remove the carbon deposits from the vehicle by the way.

6. Check the battery frequently. If the vehicle is parked for a long time, the power cord of the battery should be unplugged, so that the battery will generally not lose power, but some vehicles will also lose the security anti-theft system, and the computer program has failed, so before unplugging the power cord, you should ask the 4S shop, whether you can unplug the power cord, or take some other measures. When parking, the battery should be checked regularly and the battery should not be over-discharged.

The way to deal with a car parked for a long time is:1. The tire pressure should be adjusted to the upper limit.

2. Fill the fuel tank with fuel and turn off the whole car circuit.

3. Drain all the antifreeze in the cooling system and drain the oil.

4. The battery should be removed after the pile is fully charged, and it should be charged regularly during the parking period.

5. Use a reliable jack to frame the car so that the tires and suspension elements are no longer stressed.

If the car is not used for a long time, it is recommended that the owner start the engine once a month, check the operation of the engine, and adjust and repair it in time if there is any abnormal phenomenon.

Vehicles that have been stopped for a long time will gradually deteriorate the technical condition of each assembly and mechanism due to atmospheric erosion, resulting in the loss of original technical performance. To mitigate this adverse effect, the owner should always carry out the necessary maintenance work on the stopped vehicle to keep it in good performance condition. So do you know how to maintain the car when it is parked for a long time?

1. Prevent the aging and deterioration of rubber products

Rubber products on automobiles, such as tires, transmission belts and dust covers, often age, swell or shape, resulting in deterioration of performance and shortened service life.

Like the aging of rubber products, it is mainly due to the fact that rubber is an unsaturated polymer hydrocarbon, which is easy to absorb oxygen in the air and oxidize, and vulcanized rubber also has a certain air permeability, and oxygen is easy to enter the interior to oxidize. In particular, direct sunlight can promote the rapid aging of rubber. When rubber products are stained with gasoline and engine oil, it will cause the volume to expand, the gum to become loose, and the elasticity to decrease.

In order to prevent the aging of rubber products, direct sunlight and mineral oil contact should be avoided.

2. Prevent metal rusting

Rust is mainly caused by the combined action of moisture, oxygen and corrosive substances in the air. Therefore, for cars that have been parked for a long time, the metal surface should be kept clean. The garage where the vehicle is parked should be ventilated frequently so that the relative humidity of the air is kept below 70%.

Dust, dirt and moisture need to be removed from the car in a timely manner. The parts that are easy to rust and the surface of the parts should be coated with oil, grease or wrapped with oiled paper. The pores on each assembly mechanism should be sealed to prevent air, moisture and dust from entering the interior.

3. Prevent mildew and carpet of cotton and linen products, which are easy to absorb water.

Especially in humid areas and rainy seasons, it is more susceptible to damp mildew. Therefore, the owner should check the cotton and linen products on the car frequently, dry them in a timely manner, and keep them dry.

4. Prevent the anti-knock performance of gasoline from decreasing

The anti-knock performance of gasoline is determined by the octane number of gasoline. When the car is stopped for a long time, the octane number of gasoline decreases with the loss of light components and the increase of gum content, so that its anti-knock resistance is reduced. Therefore, the gasoline tank should be tightly closed and the temperature should not be too high.

It is best not to store gasoline for too long.

5. Check the working condition of the engine frequently

Start the engine at least once a month, idle for 4-5min, and check the operation of the engine. If there is any abnormal phenomenon, it needs to be adjusted and repaired in time.

Also, check the battery frequently. The electrolyte level of the battery must be 10-15mm higher than the plate, and distilled water should be added in time when it is insufficient, and the power should be kept sufficient, and the battery should be charged if necessary.

(1) Be sure to choose a good parking spot.

The garage where the vehicle is parked should be kept ventilated at all times so that the relative humidity of the air is maintained.

70% or less. For the location of long-term parking of vehicles, choosing to be outdoors is the next policy, outdoor uncertain factors are more, such as acid rain (in fact, most cities in China due to air pollution, the rain quality is acidic), snow, wild dogs and wild cats urine and other corrosion, falling objects, fireworks are also likely to make your car encounter accidents. And a car that has been parked for a long time is also easy to be scratched by some naughty children and smashed glass.

There are also some underground garages with poor air circulation and high humidity, which is also easy to cause rust on vehicle parts. So the best place to park should be in a ventilated garage, such as a multi-storey garage on the ground. Before parking, it is best to apply oil and grease to the parts that are easy to rust and the surface of the parts.

The pores on each assembly mechanism should be sealed to prevent air, moisture and dust from entering the interior. （2

Take good care of your tires.

If the parking period is more than one month, not only should the tire pressure be adjusted to the upper limit, but also the vehicle should be moved regularly every other week for a few centimeters, so as to avoid the deformation of the radiant steel wire caused by the compression of the tire in a fixed position. A more effective way is to use a sturdy jack to frame the car before it stops, so that the tires and suspension elements are no longer stressed. （3

Wash and tidy up your car.

Before the car is parked, clean the whole car and do not leave mud stains. Fill up the tank with fuel and turn off the entire vehicle circuit. （4

Drying carpets in the car.

Cotton and linen products such as carpets on the car can easily absorb moisture. Especially in humid areas and rainy seasons, it is more susceptible to damp mildew. Therefore, it is best to entrust family and friends to check the cotton and linen products on the car frequently and keep them dry. （5

Gasoline tanks should be tightly sealed.

When the car is stopped for a long time, the octane number of gasoline decreases with the loss of light components and the increase of gum content, so that its anti-knock resistance is reduced. Also for safety reasons, the gasoline tank must be tightly closed, and avoid excessive temperature, and it is best not to store gasoline for too long. （6

Start the engine once a month.

If the car is not used for a long time, it is best to ask a family member or friend to start the engine once a month to check the operation of the engine. If any abnormal phenomenon is found, it should be sent for repair in time. （7

Drive a mile per week.

This is for the same reason as above, driving a certain range of miles per week (preferably at high speeds) not only keeps the battery charged, but also keeps the various parts of the vehicle functioning properly. （8

Old-fashioned batteries should be refilled in time.

For non-additive-free batteries, the electrolyte level needs to be checked during the shutdown process. It should be noted that the liquid level height must be higher than the plate 10a.

15 ml, distilled water should be added in time when insufficient. At the same time, it is necessary to keep the battery sufficient, and if necessary, the battery should be charged. （9

Empty part of the fluid if necessary.

Time to park the vehicle to prevent the vehicle from getting dust, ventilate the inside of the vehicle every week, and also check the engine is the best to start the vehicle, if there is an abnormality, it is necessary to repair it in time with the car shop.

Sometimes for some reason, we need to teach our vehicles to park for a while, and we all know that mechanical things are prone to problems if they are not used. For this is a headache for many drivers, if the vehicle is parked for a long time, how should we maintain it?

If you decide that the vehicle needs to be parked for a long time, be sure to clean the vehicle without stains before parking, and turn off the electrical circuits of the whole vehicle。If the vehicle is parked for more than a month, the vehicle should be moved every week to prevent the tires from being squeezed in a fixed position and causing the tires to deform. If the vehicle is not used for a long time, the oil will be oxidized, and the oxidation phenomenon is more serious, once the oil oxidation lubrication effect will become very poor, and it will also cause damage to other parts.

It is best to keep the interior of the car ventilated every week after parking, especially in the rainy season, the items in the car are easy to mildew, and it is best to entrust a friend or family member to check it every week to keep the car dry. Also check the wipers, engine, to see if the wipers are operating normally, if the vehicle can not start normally, must find a person to repair in time, if not dealt with in time, then it is very likely that the car will be more troublesome in the future, long-term parking vehicles must not be placed in the outdoor parking lot to be placed in the indoor parking lot, so as to ensure that the vehicle is not exposed to the wind and sun.

Of course, it is not enough to do the above points, the best way is not to park the vehicle for a long time, and if there is really no way, you must maintain the vehicle well. Check the hood every week to prevent rats from escaping, and pay attention to the bottom of the car and its surroundings when driving.

Cleaning is important.

Before parking, the whole car should be cleaned and tidyed, do not leave mud stains, wax the body for a beauty, and prevent the body from being corroded. Put some desiccant in the car to absorb the excess water in the car. Clean up the contents of the car in a timely manner, and do not place snacks in the car.

In addition to taking food away, make special efforts to check that there are no flammable and explosive materials such as lighters and matches in the car.

Pay attention to the safety of the vehicle when it is placed.

During the rainy season, electronic components are easily damp, and when the vehicle is stopped for a long time, there is a high possibility that electronic components or plug-in connectors will get wet, causing damage to the components. Before the vehicle is parked, make sure that the entire vehicle circuit is closed to avoid moisture corrosion from rain and snow.

Check the oil for deterioration.

Engine oil plays a protective role in the parts of the car, but long-term non-use will lead to deterioration of the oil, so you must remember to replace a set before using it again, although it is expensive to replace, but it is too long to use, if you want to use it suddenly, it may damage the car, and sometimes it has to be changed to prevent greater damage.

Check if the tires are deformed.

The vehicle is parked for a long time, the contact parts of the four tires are compressed and contracted, and it is not easy to recover, and the rolling radius is uneven, resulting in unbalanced tires, and if you run at high speed, "car shock" will occur. Tire wear accelerates, and driving safety also brings hidden dangers. If it's a hot summer, the tires may also get on the ground, leaving offset marks.

Be sure to inflate the tires before they are idle, so that the tires can withstand a certain amount of pressure. Of course, if you park for more than a month, ask someone to help move the vehicle every few days, so that the tires do not have to be pressed in one position.

Check the battery and charge it.

Now the car is generally used lead-acid battery, once the car stops running, it will produce self-discharge, under normal conditions, self-discharge every day and night can reduce the electric capacity by more than 1%, long-term self-discharge, sulfide on the surface of the plate, affect the battery recharge effect, enter the scrap state in advance.

As for how long the battery will be dead, it varies from car to car. Many cars run out of power after a few weeks of parking, mainly due to excessive theft current generated within the electrical system, and the size generally increases with the age of the vehicle.

The dust on the battery and the oxide on the terminal post and wire, as well as the electrolyte at the liquid filling port, should be cleaned to prevent the battery from discharging by itself. If the battery voltage is insufficient, the light is dim or the starting is weak, timely replenish the charge outside the vehicle.

Special Tips. When the vehicle is placed for a long time, you must remember to take protective measures, otherwise a small mistake will cause a lot of maintenance sequelae, so as not to lose more than you gain.
