How do I maintain my car?

1) Spring maintenance. Winter is turning to spring, and the weather is getting warmer. For spring maintenance, first refer to the vehicle instruction manual to comprehensively check the tire pressure; add or replace coolant in a timely manner, do not replace it with clean water; add anti-static equipment on the vehicle to prevent the human body from carrying static electricity, and avoid static electricity from interfering with or penetrating parts of the vehicle Electrical equipment; when the car body is covered with sand and dust, do not wipe it with a duster to prevent the duster carrying a large amount of sand and dust from causing fine scratches on the car body; keep the air filter intact and clean to prevent malicious harassment such as catkins and pollen; timely Clean the air conditioner condenser radiator and coolant radiator to prevent the coolant temperature from being too high due to blockage; do not open the external circulation to prevent dust from being sucked into the air conditioning system; when driving, carefully check whether the hoses in each part are damaged or aged. , if any, they must be replaced; pay attention to check whether the drainage holes on the left and right sides are blocked to prevent rainwater from being drained smoothly and pouring into the car after rain.

2) Maintenance in spring and summer. At the turn of spring and summer, the weather is changeable. For seasonal maintenance, the most important thing is the selection of lubricating oil and the cleaning and protection of the lubrication system; when choosing lubricating oil, try to choose SJ (15W-40) or above for EFI vehicles, and SJ/SL semi-synthetic is best for high-end vehicles. oil or synthetic oil; clean the inside of the engine without disassembly and add engine protective agent; in addition to cleaning the dirt and oil on the outer surface of the engine and compressor, you must also clean the radiator, air-conditioning air intake screen and evaporation box; clean the air-conditioning ventilation pipe Carry out a thorough cleaning and disinfection of the road; check the tires regularly in strict accordance with the air pressure standards stipulated in the vehicle owner's manual to ensure that the tire pressure is slightly low and the air pressure of the left and right wheels is consistent. Also pay attention to check the wear degree of the tire surface and whether there are nails on the surface. Regularly check the tire pressure. Spray protective agent on the tires; when the weather turns hot, park the car in a garage or a cool place as much as possible. If it is parked outdoors for a long time, it should be covered with a car cover. It is best to apply a layer of explosion-proof solar film proportional to the entire car; in summer Before, you can give the car a "sauna".

3) Summer maintenance. Entering summer, the climate is hot. During summer maintenance, be sure to prevent heatstroke and cool down to avoid spontaneous combustion of the car; when exposed to high temperatures for a long time, pay attention to the cooling measures of the cooling system; for the liquid level of the radiator coolant, the liquid level of the crankcase oil and brake fluid, The electrolyte density and liquid level in the battery should be checked frequently. If any abnormality is found, it should be added and adjusted in time. Pay close attention to the tires to see if they are bulging too much or measure the tire pressure and deflate a little if necessary. After a long period of time in summer, After driving or driving at high speed, you should stop the car to dissipate heat, and it is strictly forbidden to splash water to cool down; in order to prevent the engine from overheating, you should pay attention to the fan drive belt not to be stained with engine oil during maintenance to prevent slipping, and try to keep the drive belt tight and appropriate; replace the crankcase and gear box with When using lubricating oil in summer, always check the quantity and quality of the lubricating oil, and replace it in time; insist on using antifreeze formulated with chemical ingredients such as ethylene glycol to avoid the trouble of "boiling the pot".

4) Alternate maintenance in summer and autumn. Summer and autumn alternate, and the weather becomes cooler. Seasonal maintenance should start with antifreeze. If you like to use tap water instead of antifreeze in summer, you should replace the tap water with antifreeze in time after the beginning of autumn; check the battery electrode connections, if there are green oxides, be sure to flush them with boiling water; do a thorough maintenance of the air conditioner, and pay attention Maintenance of heating air pipelines and fans; pay attention to whether the defrost air outlet under the windshield glass is flowing normally and whether the heat is sufficient. If problems occur, solve them in time; when the temperature drops, add air pressure to keep it within the specified air pressure range; Check the degree of wear of the tire tread. If the tire tread depth is less than 1.6 mm, replace it with a new tire; if the car body has obvious scratches, it should be spray-painted in time; it is best to do a cleaning, polishing, waxing, and Cosmetic maintenance of glaze or coating and a thorough interior sterilization and cleaning.

5) Autumn maintenance. Autumn is here and the weather is getting cooler.

For autumn maintenance, we must first start with the tires, replenish the air pressure in time to keep it within the specified range, and check whether there are scratches on the tires; remove rust from the chassis, and check whether there are scratches or loose screws on the chassis; comprehensive Check the brake system, perform corresponding cleaning, lubrication, rust removal, etc., check whether the brakes have weakened or deviated, and whether the pedaling force of the brake pedal has changed. If necessary, clean the entire brake system pipeline. parts to ensure normal system performance; oil, fluids, and electricity are items that cannot be ignored in routine car maintenance. Engine oil, brake fluid, and coolant are like the blood of the car and must be replaced during the replacement cycle to ensure smooth oil circulation; check Coolant, glass cleaning fluid and other liquids to prevent deterioration; check various plugs to ensure normal plug contact and normal waterproof sealing function.

6) Seasonal maintenance in autumn and winter. Autumn and winter turn, and the weather gets colder. Seasonal maintenance is mainly based on pre-inspection: check whether there are obvious scratches on the exterior of the vehicle, and if so, please paint the exterior in time; check whether the engine oil is suitable for all seasons, if not, please change it to an oil more suitable for winter use in time; Check whether the oil used in the transmission, transfer case, differential, steering gear and other parts is correct; check whether the antifreeze needs to be replaced; check whether the braking system is normal, check whether the brake fluid is sufficient and whether the quality has deteriorated. If necessary, It should be refilled or replaced in time; check whether the brakes are weakened or deviated, the pedaling force of the brake pedal and the position of the wheel locking point during braking; clean the pipeline part of the entire braking system if necessary; check the battery Check whether the joints are loose or corroded. If they are loose, please tighten them with an adjustable wrench. If they are corroded and have alkali, just flush them with hot water. Check whether there is any problem with the air conditioner. If so, please repair it in time. Check the air inlet or air inlet grille, Check whether there are any debris in the electronic fan and other places. If there are any, please use compressed air to blow them away; check whether the tires have obvious trauma, scratches and whether the tire pressure is standard, and pay attention to regularly cleaning the inclusions in the tire tread; check the wiper blades, etc. Check whether the rubber products are aging. If they are, they need to be replaced. Check whether the glass washer fluid storage tank is filled with tap water. If it is, the storage tank will freeze and crack when it freezes in winter. After cleaning the vehicle interior, use a protective agent to care for it. , can make the car interior parts look brand new.

7) Winter maintenance. Autumn turns to winter, and the weather is cold. For winter maintenance, you must first ensure that the oil line is smooth and the mechanism must be normalized. The fuel pump, high-pressure pump, fuel injection, etc. meet the requirements, the sealing of the valve and piston ring is good, the valve clearance, ignition (fuel injection) timing and valve phase are correct, the cylinder pressure, and the tightness of the large and small watts are appropriate; secondly, ensure that the circuit Works fine. The intensity of the low-voltage fire and high-voltage fire is appropriate, the damping of the high-voltage line, the insulation level of the flame distributor, the thermal effect of the glow plug are good, the ignition coil and spark plug are working properly, and the starting speed meets the regulations; fuel and lubricating oil are selected according to the instructions, and the ambient temperature It should be correctly matched with the fuel brand; appropriate measures should be taken to keep the vehicle warm; during winter car maintenance, a drying and dehydrating maintenance agent for the fuel system can be added.

8) Maintenance in winter and spring. Winter and spring alternate, cold and warm. During seasonal maintenance, a comprehensive inspection and maintenance should be carried out in a timely manner. First of all, give the car a comprehensive interior cleaning; secondly, the body paint should be maintained as necessary. In addition, after a cold and snowy winter, the inspection of the chassis and tires cannot be neglected. Since the snow melting agent has a certain corrosive effect, the chassis must be thoroughly cleaned. For car tires, a comprehensive inspection is necessary. In addition, it is best to replace lubricating oil with a viscosity grade suitable for the season when the season changes. During seasonal maintenance, maintenance staff will conduct more than 10 routine inspections on your car.

9) The focus of seasonal maintenance is the body and chassis. Daily maintenance belongs to "health maintenance", which is focused inspection, adjustment and health care. It is characterized by "focusing on maintenance" and aims to maintain the health of the car. Seasonal maintenance belongs to "rehabilitative maintenance", which is a comprehensive and systematic detection, adjustment and injury treatment. It is characterized by "treatment first" and aims to restore the health of the car. After a car has been driven for a season and a certain mileage, metal parts will wear and corrode, and rubber seals will inevitably age and lose elasticity. This degradation process of quality and performance will develop abnormally with changes in temperature that are too high or too low. During seasonal maintenance, the focus is on the body and chassis.

10) Pay attention to the four liquids during seasonal maintenance. Seasonal maintenance of vehicles in use is generally completed by the driver. The content of the seasonal maintenance center includes replacing lubricating oil and coolant that meet seasonal temperature requirements, adjusting the fuel supply system and charging system, and checking the working conditions of the cooling system and heater system.

Seasonal maintenance is a comprehensive maintenance of the car. It should be combined with seasonal maintenance to adjust the car's condition and eliminate faults that have occurred in the past in a targeted manner so that the car can drive smoothly and safely.
