4. The technical condition of each assembly should be balanced as much as possible to extend the mileage between automobile overhauls.

5. Reduce the pollution of vehicle noise and emission pollutants to the environment.

Repair misunderstandings. 1. Blindly remove the engine thermostat.

If the thermostat is blindly removed due to high engine temperatures, coolant.

It can only carry out large cycles, can not adjust the cooling intensity, it is difficult to ensure that the engine works at a more suitable temperature, but makes the engine often work at a low temperature, resulting in a decrease in engine power, accelerated wear and tear, and an increase in fuel consumption.

2. The engine temperature is not afraid of high or low.

Some people think that the engine temperature is not afraid of high or low when driving. In fact, when the engine temperature is low, it is also very harmful. The service life of the engine should be ensured by driving at the normal temperature specified in the car's instruction manual.

3. The tighter the belt of the water pump fan, the better.

The tighter the belt, the better. If the belt is too tight, it will not only elongate or break, shortening the service life of the belt, but also lead to deformation and bending of the generator shaft and water pump shaft and early damage to the bearing due to excessive tension. Car engines.

The tightness of the fan belt should meet the technical requirements, and the deflection of the normal belt assembly is 10-15mm.

Through automobile maintenance, maintaining and restoring the technical condition of the car and maintaining the working ability of the car can improve the application effect of the car and prolong the service life of the car.

The role of automobile maintenance: through the technical maintenance of the car, the technical condition of the car can no longer decline or delay the rate of decline. The requirements that should be met are as follows, often in good technical condition, ready to go out of the car.

Under the premise of reasonable use, it will not stop due to damage on the way, and affect driving safety due to mechanical failure. Reduces the consumption of fuel, lubricants, as well as accessories and tires during operation. The technical condition of each assembly should be balanced to extend the mileage between vehicle overhauls.

Reduce the pollution of vehicle noise and emission pollutants to Huanqing Huijing.

In the process of using the car, under the combined action of the load and the external environment, due to wear, fatigue, corrosion, deformation and other reasons, the technical condition of its parts and components continues to decline or be damaged, so that the performance of the car decreases or will decline.

However, if the degree of damage and deterioration is still within the range of recovery, it can be repaired to restore its technical condition to good technical condition.

The premise of car maintenance, the car has or is about to break down and needs to be repaired, and the car has remanufacturability functions and can be repaired.

The main purpose of automobile maintenance is to maintain or restore the performance of the car, prolong the service life of the car, and maintain the normal operation of the social transportation function.

Modern automobiles are complex, high-tech products that are increasingly expensive to produce, build and use, and have an increasing impact on social safety and the environment.

Maintenance can make the car collapse continue to maintain its safety and reliability, improve transportation efficiency, save the total cost of use, and prolong the service life. Therefore, the role of maintenance is becoming more and more important, and the maintenance technology is becoming more and more complex.

Hello, (1) The safety precautions and operating procedures specified in the maintenance manual require maintenance personnel to be familiar with and strictly abide by them.

2) When the vehicle is overhauled, the ignition key should be removed to prevent others from starting the vehicle.

3) When overhauling the fuel system of the EFI engine, the oil circuit must be depressurized first to prevent gasoline leakage and splashing on the leaking high-voltage line or high-temperature objects, causing combustion. When overhauling the airbag, the negative wire of the battery must be disconnected, and the airbag must be handled with care when disassembling and disassembling the airbag. When welding the car body, the negative electrode of the battery should be disconnected to prevent damage to the vehicle computer.

4) When repairing the engine in running state, attention should be paid to prevent fan blades from being injured or high-temperature parts from burning the human body. When the engine water temperature is very high, the radiator cover cannot be opened directly by hand to prevent the pressure of the hot liquid from scalding the personnel.

5) Before starting the engine, check that the oil and coolant meet the requirements; whether the gear lever is in neutral position; Tighten the hand brake. Doors and windows should be opened to allow air to flow freely when starting indoors. After starting, the oil or gas circuit should be cut off immediately to avoid "speeding" accidents.

When testing the engine, it is not allowed to work under the vehicle.

6) When the braking system is deflated, a special reservoir bottle should be connected to the deflation bolt to prevent the brake fluid from splashing and damaging the eyes or splashing on the tires and paint. After the braking system is repaired, the braking system should be deflated or the brake pedal should be stepped on a few times, and when the brake pedal is suitable, it can be driven in gear.

7) When overhauling the automobile circuit, do not pull the wires indiscriminately. For the fault of frequent fuse, the cause of the failure should be ascertained, and the fuse should not be replaced with a large-capacity fuse or replaced with a copper wire.

8) When working under the car, it is necessary to ensure that the car support is reliable, and do not use fragile objects to support the car.

9) When baking paint in the paint baking room, the baking time of the car is generally 30-40min, and the temperature is generally 60-70, so as to prevent the damage of the car computer or the aging of the line caused by too long or too high temperature.

10) When the mailbox needs to be oiled to repair, fireworks should be strictly prohibited around, and the welding operation should be stopped.

11) When assembling the assembly, the correct operation method should be adopted to avoid injury and even major accidents.

12) When working next to the running parts, always pay attention to the safe working distance from the moving parts.

13) To disassemble the parts under high temperature and high pressure, it is necessary to cool down and depressurize to prevent high temperature scalding or high-pressure jet injury.
