A list of the 8 main points and costs of car maintenance in the hot summer[汽车维修知识]

1. Engine oil
In summer, the matching of engine and engine oil is particularly important. In high-temperature seasons, you should choose engine oil with relatively high viscosity. Because the water temperature in the engine is high in summer, it is very easy to cause the oil viscosity to decrease, and the decrease in oil viscosity will cause the oil to oxidize. It is easy to turn black and is accompanied by a fishy smell. At this time, it needs to be checked and replaced in time during the maintenance period, or replaced in advance. In summer, some cars ignite spontaneously, which is largely related to the age of the car.CarThe circuit is modified. Some bad circuits can cause excessive instantaneous current, which is easy to spontaneously ignite under high temperature conditions; aging pipelines are easy to spew out when the oil pressure increases, and they are easy to spontaneously ignite when encountering high-temperature ignition points.
Oil replacement cost (including replacement of the oil compartment): 200-300 yuan
Reminder: Try not to let the car run too long on the high-temperature highway.
2.Wiper
When you park your car under the sun without any shade, the wiper will become soft due to the baking of the sun. At this time, if the temperature of the front windshield is baked by the sun too high, the plastic of the wiper will be deformed due to overheating. , When it rains, the wiper not only cannot wipe off the rain normally, but also damages due to structural deformationCar glass. The technician told reporters that in summer, special curing agents can be used for spraying and curing. After spraying, the wiper will not be easily deformed. In addition, the rubber strips around the doors and windows can be sprayed and maintained in the same way.
Spraying cost: 30-50 yuan
Reminder: When the car is parked outside for a long time, the wiper should be erected.
3. Car battery
When the battery temperature is high, the electrode will be oxidized due to the aging of the insulating layer, especially the negative electrode, which will produce white oxide on the electrode tip, which will cause the battery voltage to be unstable. At this time, the battery needs to be inspected and maintained to protect the battery. , To prevent its early leakage. Some models also need to add battery water, because the high temperature will cause the battery water to evaporate and lower the liquid level, and the electrode plates will be exposed and accelerated oxidation.
Cost: about 20 yuan.
Reminder: This inspection is especially necessary in high temperature environments.
4.Antifreeze
Antifreeze can not only make the engine and itsCooling systemIn the cold, it will not be damaged by freezing, and it also has the functions of anti-rust, anti-boiling, and anti-scaling. Of course, the new car does not need to be replaced in the first 2 years after the purchase, but the antifreeze should be replaced regularly after the "insurance period".In the summer, the inspection of antifreeze is mainly to see whether its liquid level is below the standard liquid level at high temperatures, but it should not be added too much. In addition, the pipes, cylinder walls and theWater pumpIs it normal?
Cost: Free replacement or about 20 yuan
Reminder: Don't go to the roadside store to replace the antifreeze.
5. Air conditioning maintenance
To do a comprehensive inspection and maintenance, we must first checkCondenser, In order to ensure that the entire air-conditioning system can work normally, the cooling effect is good, and maintainCondenserThe cleanliness of the surface is essential. For this reason, the condenser should be cleaned frequently to prevent oil, dirt and other debris from attaching to the condenser. When cleaning, be careful not to knock down the condenser fins, let alone damage the tubes. In addition, the air filter should be cleaned once a week to prevent dust and debris in the car from adsorbing on the air filter and obstructing air circulation, resulting in insufficient cooling capacity. In addition, check the rubber hose frequently, and deal with it in time if there is abrasion, wrap the broken parts with cloth, and stop using the air conditioner to repair it as soon as possible.
Air conditioning cleaning cost: 10 yuan
Reminder: When leaves and other debris accumulate in the air inlet of the air conditioner, open it in timeEngine coverRemove these debris to avoid blocking the air inlet and condenser.
