Knowledge about car maintenance in hot weather
1. How to maintain your car in hot weather?
Do not drive for a long time. In hot and scorching conditions, you should try to avoid driving for a long time.
When parking, you should try to choose a cool and ventilated place. If conditions permit, you can also open the engine hood for ventilation and heat dissipation. If necessary, you can also pour cold water on the radiator, and be careful not to wet the circuit.
This requires car owners to develop a good habit of regularly cleaning the radiator fins in summer. Cool your tires frequently to avoid punctures. Pay special attention to tire pressure in summer.
Drive strictly in accordance with driving conditions and speed limits, and do not drive at high speed for a long time. If conditions permit, you can park the vehicle in a cool place to cool down the tires after driving for a period of time. However, do not pour cold water on hot tires to avoid tire deformation and affect normal driving.
Pay attention to commercial insurance. Commercial insurance is a good way to reduce the losses of car owners.
2. How to maintain a car on hot days
1. The engine water temperature is too high, antifreeze needs to be added. High engine water temperature is mostly caused by lack of antifreeze. Park the vehicle in a cool place to cool down. Do not turn off the engine. Let the engine continue to idle. Open the machine cover to dissipate heat. When the temperature drops, add antifreeze to the water tank. Avoid adding antifreeze to the water tank. Pouring cold water on the engine may cause the engine block to explode beyond repair. Some car owners simply use tap water instead of antifreeze. This is a wrong approach because there are many impurities in the water that tend to leave sediment in the engine, water tank, etc., so antifreeze cannot be replaced with water.
2. Check the cooling system and clean the radiator in time. You should also check whether the "thermostat" is working properly, and never remove the "thermostat". Because the "thermostat" is a switch that controls the circulation of coolant, it can keep the engine operating temperature within an optimal range. In this way, the engine will have the strongest power, the least wear and the lowest fuel consumption. If it is removed, it will cause Wear of parts and low water temperature will lead to a decrease in power and an increase in fuel consumption.
3. Clean the water tank and condenser. The water tank and condenser are important components of the vehicle cooling system and air conditioner. As the vehicle is used for a long time, dust, sediment, catkins, etc. will be mixed in the gaps between the two, which will affect the water temperature and air conditioning refrigeration performance. performance.
4. Adjust tire pressure in time. The high road temperature in summer reduces the heat dissipation of tires and can easily cause tire blowout accidents. Therefore, the tire pressure should be lowered. After driving a long distance for a period of time, park the vehicle in a cool place to cool the tires naturally. Do not pour cold water on the tires to avoid tire deformation.
5. Avoid spontaneous combustion of vehicles under high temperatures. Vehicle spontaneous combustion is mainly caused by vehicle leakage or oil leakage. If the car is not properly maintained, the parts are aging and the wiring is damaged, it is easy to leak electricity. The fuel tank is prone to oil leakage if it is corroded for a long time. Therefore, to avoid spontaneous combustion under high temperatures, we must start with car maintenance.
6. If the air conditioner is used frequently, the air duct and filter element should be cleaned in time. Furthermore, pay attention to refrigerant leakage and poor refrigeration. This is usually caused by the aging of the sealing rubber ring in the pipeline, abnormal refrigerant pressure, or damage to system components. Also pay attention to the working condition of the cooling fan.
3. How to maintain cars in hot weather
In hot weather, the technical condition of the car changes due to high temperatures, heavy dust and strong radiant heat.
In order to meet the needs of normal operation of the car, during high temperature seasons, some necessary seasonal inspections and adjustments should be made to the entire vehicle in conjunction with secondary maintenance. 1. Strengthen the use and maintenance of the cooling system.
Pay attention to check the sealing condition of the cooling system, the tightness of the fan belt, the sensitivity of the thermostat and the temperature of the cooling water, etc., and make sure there is sufficient cooling water; clear the cooling system including the radiator and water jacket Adhering scale inside. Because scale has poor thermal conductivity, it will seriously affect heat dissipation.
2. Pay attention to the use of various types of oil. The engine should be replaced with high-viscosity lubricating oil and the oil change interval should be shortened appropriately; the transmission and differential should be replaced with thick gear oil; the wheel hub bearings should be replaced with grease with a higher dropping point, and inspection and maintenance should be carried out according to the prescribed intervals; Brake fluid may cause vapor lock at high temperatures, so brake fluid with a high boiling point (not less than 115~120 degrees Celsius) should be used.
3. Adjust the carburetor. Appropriately lower 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 charging system. When driving at high temperatures, the battery will be overcharged, the electrolyte evaporates quickly, and the plates are easily damaged. Therefore, it is necessary to frequently check the liquid level of the battery and the specific gravity of the electrolyte (the specific gravity of the electrolyte should be smaller than in winter), and refill the battery frequently. Distilled water; keep the vent hole on the filler cap open and unobstructed, otherwise the internal air pressure of the battery will increase and cause the casing to explode; the generator regulator should also be adjusted appropriately to reduce the charging current of the generator.
5. Prevent bursting. Gasoline with corresponding octane number should be selected according to the engine compression ratio. If the gasoline grade is lower than the required grade, a knock limiter can be installed; the engine should be kept at normal operating temperature; the ignition advance angle should be appropriately delayed and the mixture should be enriched.
6. Prevent air blockage in the oil supply system.
The vapor lock phenomenon in the high-temperature fuel supply system is due to the fact that after the fuel supply system is heated, part of the light distillate in the gasoline volatilizes into gas, which exists in the gasoline pipeline and gasoline pump, increasing the gasoline flow resistance.
Coupled with the influence of high temperature, it is easy to cause insufficient or even interrupted oil supply to the engine, making the car unable to drive or difficult to start. Specific measures to prevent air lock include: A. If air lock occurs while driving, you can use a damp cloth to cool the gasoline pump or drive the car to a cool place to cool down and eliminate it.
B. Change the installation position of the diaphragm gasoline pump from the original location close to the rear side of the exhaust pipe to a well-ventilated area in front of the exhaust pipe, and add a seal between the gasoline pump and the exhaust pipe. Install a heat shield. C. An old one-way oil valve spring can be installed on each of the inlet and outlet valves of the gasoline pump to improve the resistance of the gasoline pump to air resistance.
D. Try to improve or select a new type of gasoline pump (for example, if the original 262 type gasoline pump's resistance to air resistance is not ideal enough, you can choose a 266 type gasoline pump and install a transistor electric gasoline pump. The pump is not affected by the installation location. limit) to prevent air blockage. 7. Prevent tire blowout while driving.
When the temperature is high, the temperature inside the tire increases, the internal air pressure increases, and the tire is prone to puncture. Therefore, when the car is running at high temperatures, you should pay more attention to the temperature and air pressure of the tires and check them frequently to maintain the specified air pressure standards.
When driving on a hot day at noon, the driving speed should be appropriately reduced. You should stop in a cool place every 40 to 50 kilometers and wait until the tire temperature drops before continuing to drive. Do not use deflation or pouring cold water to reduce pressure and temperature to avoid accelerating tire damage.
4. Tips for car maintenance in summer
Car maintenance is actually the same as that of people. The work should be done at ordinary times. Don’t be like some people who only go to the hospital when they are sick and can’t stand it anymore. Hospital, that would be a bit late, the same goes for people and cars.
1. Anti-flat tires are required when the temperature is high in summer
When the temperature is high in summer, the tire temperature increases, and the rubber is easy to soften. In severe cases, tire burning may occur. When a vehicle encounters a hard object while traveling at high speed, it is very easy for the tire to burst. Always check the tire pressure while driving. If you find that the tire is overheated or the air pressure is too high, you should park the car in a cool place to cool down. Do not pour cold water on it or deflate it, otherwise it will cause a tire blowout and early damage to the tire.
2. Prevent water shortage due to high temperatures in summer
When driving in hot weather, the water in the water tank evaporates faster. Always check the cooling water volume and pay attention to the water temperature meter. Stop the car immediately when you find there is water shortage, but do not add water immediately. Instead, wait for the idle speed to cool down before replenishing the water. Be careful not to open the radiator cover immediately to prevent burns.
3. Prevent slipping when the temperature is high in summer
Always check the working condition of the water pump and the tension of the fan belt. The fan belt should not be stained with oil to prevent the fan belt from slipping. Always pay attention to water pump leaks, and at the same time, be sure to open the blinds fully.
4. It is necessary to prevent air lock during high temperatures in summer
Due to the high temperature in summer, the heat dissipation speed is limited, the car travels slowly during driving, the engine speed is high, and heat dissipation is difficult, and it is easy to cause "driving" "Air lock", sometimes the engine will be difficult to start after being stopped for a few minutes, causing the oil supply to be interrupted. Once air lock occurs, the driver should stop the car immediately to cool down and troubleshoot the problem. If your car is hydraulically braked and driving at high temperatures and high speeds, the brake fluid is prone to air "air lock", causing the brakes to suddenly fail and cause an accident.

5. How to maintain your car on hot days
Car maintenance on hot days is also different from other seasons.
Services such as engine and air conditioner maintenance, tire replacement, film sticking, etc. that are prone to breakdowns or heatstroke prevention in summer are generally performed in professional stores. What you need to do is to master some simple maintenance tips for your car.
Keep your car away from the scorching sun. Summer temperatures are high. If a car is parked outdoors for a long time, the hot air will not be able to circulate because the doors are closed. Excessive sunlight exposure will also accelerate the aging of car interiors, especially some plastic parts.
[Expert Tips] ◆Affixing explosion-proof film Explosion-proof film can effectively reduce the heat caused by sunlight radiation from entering the car, effectively block ultraviolet rays, protect the skin from harmful ultraviolet rays, and prevent Items fade and age. ◆Install a sun visor If the car will be parked in the sun for a long time, a foldable sun visor made of soft reflective material can be placed on the front windshield.
◆To protect the paint surface, it is best to go to a professional beauty shop for a paint sealing glaze. Good-quality glaze products can help completely isolate your car from the erosion of ultraviolet rays, acid rain and wind and sand. In addition, it is best not to wash your car under the hot sun.
Reduce breakdowns while driving. The temperature is high in summer. When driving, the tire temperature increases, and the rubber is easy to soften. In severe cases, tire burnout may occur. The hot weather limits the heat dissipation speed. When the car is driving, the speed is slow, the engine speed is high, and heat dissipation is difficult, and "air lock" is prone to occur.
[Expert Tips] ◆ Vehicles with run-flat tires are prone to punctures when encountering hard objects while driving at high speeds. Therefore, you should check the tire pressure at any time while driving. If you find that the tire is overheated or the air pressure is too high, you should park the car in a cool place to cool down. Do not pour cold water on it or deflate it, otherwise it will cause tire blowout and early tire failure. damage.
◆ Anti-vapor lock Sometimes the engine is difficult to start after being stopped for a few minutes, causing the oil supply to be interrupted. Once air lock occurs, the driver should immediately stop the vehicle to cool down and troubleshoot the problem.
If your car has hydraulic brakes and is driven at high speed under high temperatures, the brake fluid is prone to air "air lock", causing the brakes to suddenly fail and cause an accident. ◆To prevent water shortage, when driving in hot weather, the water in the water tank will evaporate faster. Always check the cooling water volume and pay attention to the water temperature meter.
Stop the car immediately when you find there is a lack of water, but do not add water immediately. Instead, wait for the idle speed to cool down before replenishing water. Be careful not to open the radiator cover immediately to prevent burns. How to prevent "heatstroke" in cars The car is driving under the scorching sun.
6. Owners of Fengguang S560, do you know how to maintain your car in hot weather?
The weather has been really hot recently, and I would like to share with you how I maintain my Fengguang S560 in hot weather. Tips.
First, if you don’t want your car to be exposed to the sun, the best way is to find a shady place to park, either indoors or under the shade of a tree. Second, if you really can't find a shady place to park, there is a simple and practical method - sunshade.
When exposed to the sun, affixing sunshades on the front, rear, left, and right sides of the car can effectively isolate the sun from exposing the car to a certain extent, and can effectively reduce the temperature inside the car to a certain extent. Third, in vehicles exposed to the scorching sun in summer, the temperature inside the vehicle can reach up to 60-80 degrees Celsius. The seats, dashboard and other interior decorations in the vehicle can easily produce 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, charcoal bags, tea leaves and grapefruit peel are the three most powerful deodorizing tools. Keep some in the car. It can freshen the air inside the car to a great extent.
