Common sense of automobile maintenance in hot weather

1. How to maintain the car in hot weather?

Do not drive for a long time. In hot summer, you should try to avoid driving for a long time.

When parking, you should try to choose a cool and ventilated place, and you can also open the hood to ventilate and dissipate heat if possible. If necessary, you can also pour cold water on the radiator, and be careful not to wet the line.

This requires car owners to develop a good habit of cleaning radiators regularly in summer. Be sure to cool the tires to avoid puncture. Pay special attention to tire pressure in summer.

Drive in strict accordance with the driving conditions and speed limit requirements, and do not drive at high speed for a long time. If conditions permit, after driving for a period of time, park the vehicle in a cool place to cool the tires, but don't pour cold water on the hot tires to avoid tire deformation and affect normal driving.

Paying attention to commercial insurance is a good way to reduce the loss of car owners.

2. How to maintain the car in hot weather?

1, engine water temperature is too high, add antifreeze. Too high engine water temperature is mostly caused by insufficient antifreeze. Stop the vehicle in the shade to cool down. Don't turn off the engine, let the engine run at idle speed, lift the hood to dissipate heat, add antifreeze to the water tank after the temperature drops, and don't pour cold water on the engine. This may cause the engine cylinder to burst beyond repair. Some car owners simply use tap water instead of antifreeze, which is wrong. Because there are many impurities in water, it is easy to leave sediment in the engine and water tank, so water can not be used instead of antifreeze.

2. Check the cooling system and clean the radiator in time. Also check whether the "thermostat" works normally, and never remove it. Because the "thermostat" is a switch to control the circulation of coolant, it can keep the working temperature of the engine in an optimal range, so that the engine has the strongest power, the least wear and the lowest fuel consumption when working. If it is dismantled, it will cause parts to wear, and low water temperature will lead to a decrease in power and an increase in fuel consumption.

3. Clean the water tank and condenser. Water tank and condenser are important components of vehicle cooling system and air conditioner. With the long-term use of vehicles, dust, sediment and catkins will be mixed in the gaps between them, which will affect the water temperature and the refrigeration performance of air conditioners.

4. Adjust the tire pressure in time. In summer, the high road temperature leads to the decrease of tire heat dissipation, which is easy to cause tire puncture accidents, so the tire pressure should be reduced. After driving for a long time, park the vehicle in the shade and let the tires cool naturally. Do not pour cold water to avoid tire deformation.

5. Avoid vehicle spontaneous combustion at high temperature. Vehicle spontaneous combustion is mainly caused by vehicle oil leakage or oil leakage. Improper car maintenance, aging parts and damaged lines are easy to leak electricity. Moreover, the oil tank is prone to oil leakage due to long-term corrosion. Therefore, avoiding high-temperature spontaneous combustion should start with car maintenance.

6. Air conditioners are frequently used, so air ducts and filter elements should be cleaned in time. Furthermore, pay attention to refrigerant leakage and poor refrigeration. This is usually caused by aging of sealing aprons in pipelines, abnormal refrigerant pressure and damage of system components. In addition, pay attention to the working condition of the cooling fan.

3. How to maintain the car in hot weather?

In hot weather, due to high temperature, heavy dust and strong radiant heat, the technical condition of the car has changed.

In order to meet the needs of the normal operation of the vehicle, combined with the secondary maintenance in high temperature season, some necessary seasonal inspections and adjustments are made to the whole vehicle. 1, strengthen the use and maintenance of cooling system.

Pay attention to check the sealing condition of cooling system, the tightness of fan belt, the sensitivity of temperature controller and the temperature of cooling water, and pay attention to the adequacy of cooling water; Remove the scale attached to the cooling system (including radiator and water jacket). Because scale has poor thermal conductivity, it will seriously affect heat dissipation.

2. Pay attention to the use of various oils. Replace the engine with high viscosity brand lubricating oil, and shorten the oil change cycle appropriately; The transmission and differential should be replaced with thick gear oil; Replace the hub bearing with grease with high dropping point, and carry out inspection and maintenance according to the specified period; Brake fluid may cause air resistance at high temperature, so brake fluid with high boiling point (not less than 1 15~ 120℃) should be used.

3. Adjust the carburetor. Properly reduce the oil level in the float chamber, reduce the oil output of the main nozzle and valve, and appropriately delay the ignition advance angle.

4. Adjustment and maintenance of the charging system. When driving at high temperature, the battery will be overcharged, the electrolyte will evaporate quickly, and the electrode sheet will be easily damaged. Therefore, it is necessary to regularly check the liquid level height and electrolyte specific gravity of the battery (the electrolyte specific gravity is smaller than that in winter), and often add distilled water to the battery; Keep the vent hole on the fuel filler cover unobstructed, otherwise the air pressure inside the battery will increase and the shell will burst; The generator regulator should also be adjusted appropriately to reduce the charging current of the generator.

5. Prevent bursting. The gasoline with corresponding octane number should be selected according to the compression ratio of the engine. If the gasoline grade is lower than the required grade, a knock limiter can be installed. Keep the engine at normal working temperature; Properly delay the ignition advance angle to enrich the mixture.

6. Prevent the gas resistance of the oil supply system. The gas resistance phenomenon of high-temperature fuel supply system is due to the fact that some light fractions in gasoline volatilize into gas after the fuel supply system is heated, which exists in gasoline pipelines and gasoline pumps, increasing the flow resistance of gasoline.

Coupled with the influence of high temperature, it is easy to cause insufficient or even interruption of engine oil supply, which makes the car unable to drive or difficult to start. The specific measures to prevent air resistance are as follows: a. When air resistance occurs during driving, the gasoline pump can be cooled with a damp cloth or the car can be driven to the shade to cool down and eliminate it.

B, change the installation position of diaphragm gasoline pump, from the original place near the rear side of the exhaust pipe to a well-ventilated place in front of the exhaust pipe, and install heat insulation board between the gasoline pump and the exhaust pipe. C, an old one-way oil valve spring can be installed on the inlet and outlet valves of the gasoline pump respectively to improve the gas resistance of the gasoline pump.

D, try to improve or choose a new gasoline pump (such as the original 262 gasoline pump gas resistance is not ideal, can choose 266 gasoline pump, install transistor electric gasoline pump, not limited by the installation location), to prevent gas resistance. 7. Prevent puncture while driving.

When the temperature is high, the temperature in the tire rises, and the internal air pressure rises, which is easy to puncture. Therefore, when the car is driving at high temperature, it should pay more attention to the temperature and air pressure of the tire and check it frequently to maintain the specified air pressure standard.

When driving at hot noon, you should appropriately slow down the driving speed, stop in the shade every 40~50 kilometers, and continue driving after the tire temperature drops. Do not deflate or pour cold water on the way to reduce pressure and cool down, so as not to accelerate tire damage.

4. Tips for car maintenance in summer

In fact, the maintenance of cars is the same as that of people. Work should be done at ordinary times. Don't go to the hospital like some people are sick and can't stay up. That's a little late. People and cars are the same.

1, explosion-proof tires are needed for high temperature in summer.

When the temperature is high in summer, with the increase of tire temperature, rubber is easy to soften, and tire burning will occur in severe cases. Vehicles encounter hard objects at high speed and are prone to puncture. Check the tire pressure at any time while driving. If the tire is overheated and the air pressure is too high, park the car in the shade to cool down. Don't spill or deflate cold water, otherwise it will lead to tire puncture and early tire damage.

2. High temperature in summer needs to prevent water shortage.

Driving in hot weather accelerates the evaporation of water in the water tank. Always check the cooling water quantity and pay attention to the water thermometer. Stop immediately when you find water shortage, but don't add water immediately. Instead, replenish water to cool down after idling, and be careful not to open the radiator cover immediately to avoid being burned.

3, high temperature in summer needs anti-slip.

Always check the working condition of the water pump and the tension of the fan belt. The fan belt should not be stained with engine oil to prevent the fan belt from slipping. Always pay attention to the water leakage of the pump, and at the same time pay attention to fully open the shutters.

4, high temperature in summer need to prevent air resistance.

Due to the high temperature in summer, the cooling speed is limited, the speed of the car on the way is slow, the engine speed is high, and it is difficult to cool down, which is prone to "air resistance". Sometimes it is difficult to start the engine after stopping for a few minutes, which interrupts the oil supply. If there is air resistance, the driver should immediately stop to cool down and troubleshoot. If your car is hydraulically braked and driving at high temperature and high speed, the brake fluid will easily produce air "air resistance", which will cause the brakes to suddenly fail and cause an accident.

5. How to maintain the car in hot weather?

In hot weather, car maintenance is also different from other seasons.

Such as engine and air conditioning maintenance, tire replacement, film pasting, etc. Some services that are prone to failure or heatstroke prevention in summer are generally carried out in specialty store. What you need to do is to master some simple car maintenance skills.

Keep your car away from the scorching sun and the high temperature in summer. If the car is parked outdoors for a long time, the hot air often won't circulate because the door is closed. Too much sunlight will also accelerate the aging of automobile interiors, especially some plastic parts.

[Expert Tips] Sticking explosion-proof film explosion-proof film can effectively reduce the heat generated by sunlight radiation from entering the car, effectively block ultraviolet rays, protect the skin from harmful ultraviolet rays, and prevent the items in the car from fading and aging. ◆ Installing a sun visor If the car is to be parked in the sun for a long time, a foldable sun visor made of reflective soft material can be placed on the front windshield.

◆ To protect the paint surface, it is best to go to a professional beauty shop to seal the paint surface. High-quality glaze products can help your car completely isolate from ultraviolet rays, acid rain and sand erosion. In addition, it is best not to wash the car in the hot sun.

Reduce failures during driving. When the temperature is high in summer, the tire temperature rises when driving, and the rubber is easy to soften. In severe cases, tire burning will occur. The heat dissipation speed is limited by the hot weather, so that the speed is slow, the engine speed is high, the heat dissipation is difficult, and "air resistance" is easy to appear.

[Expert advice] ◆ Tire-proof vehicles are prone to puncture when they encounter hard objects at high speed. Therefore, it is necessary to check the tire pressure at any time during driving. If the tire is overheated and the air pressure is too high, stop the car in the shade to cool down, and don't splash or deflate it with cold water, otherwise it will lead to a puncture on the way and early tire damage.

◆ Air resistance sometimes makes it difficult to start the engine after stopping for a few minutes, which interrupts the oil supply. In case of air resistance, the driver should immediately stop to cool down and troubleshoot.

If your car is hydraulically braked and driving at high speed at high temperature, the brake fluid will easily produce air "air resistance", which will cause the brakes to suddenly fail and cause an accident. ◆ When driving in water-deficient and hot weather, the evaporation of water in the water tank is accelerated. Always check the cooling water quantity and pay attention to the water thermometer.

Stop immediately when you find water shortage, but don't add water immediately. Instead, replenish water to cool down after idling, and be careful not to open the radiator cover immediately to avoid being burned. How to prevent the car from "heatstroke". Under the scorching sun, the car is driving.

6. Does the owner of Scenery S560 know how to maintain his car in hot weather?

It's really hot recently, so I want to share with you my tips on maintaining the scenery S560 in hot weather.

First, if you don't want to expose your car to the sun, the best way is to find a shady place to park, either indoors or under the shade of a tree. Secondly, if you really can't find a cool place to park, there is a simple and practical method-shading.

When exposed to the sun, you can stick parasols on the front, back, left and right sides of the car, which can effectively isolate the sunlight from the car and effectively reduce the temperature inside the car to a certain extent. Third, the vehicle is exposed to the hot sun in summer, and the highest temperature in the car can reach 60-80 degrees Celsius, and the accessories such as seats and instrument panels in the car are prone to odor.

If you are exposed to the sun for a long time, open all four doors before entering the car to let the smell evaporate. In addition, grapefruit peel and charcoal tea are three deodorizing artifacts. Putting some in the car can greatly remove the air in the new car.
