When you put the sewer truck to the repair shop and describe to the maintenance worker the performance or the problem of the car, pay attention to the noise and symptoms associated with it. It can be said that the more you learn about the car, the better it can describe the car breakdown and help the maintenance worker make the correct diagnosis, and thus can prescribe the right medicine.
New or abnormal noise is usually an indicator of a car failure. For example, the low-pitched sound may be a bearing failure, or it may be just a problem with a tire; the screaming sound may indicate that the brake pad needs to be replaced or the belt is loosened. When describing a malfunction, it is best to clearly explain the cause or action of the noise.
In addition to the loss of performance or noise, the indication signal on the instrument panel is another place that can not be ignored. Carefully read the car's user manual to understand the meaning of various signals, can help you find new faults in a timely manner.
If you feel that the steering wheel is tightened, the car is leaning to one side, or there is abnormal vibration in a certain speed range while driving, you need to check the tires, or balance and position the wheels. Repairs in time when these problems have just been discovered can prevent the continued expansion of failures and avoid even greater losses.
Special attention should be paid to the braking system, because the braking system has a very close relationship with driving safety. Ignoring such failures is tantamount to taking personal and other people's lives as risk-taking.
Pay attention to whether the car starts smoothly. If the car starts to become difficult to start, it is best to drive to the repair shop in time for maintenance.
In poor traffic - traffic jam or long idle time, the engine water temperature gauge shows too high, the electronic fan high gear working time is too long, the engine noise increases, the air temperature is too high when the air conditioning is the most obvious failure.
Using Vacuum Gauges to Diagnose Engine Faults How to Prolong the Service Life of Engine Valve Trains
1. When the air temperature is too high to open the air conditioner, the idling speed is too fast, the speed is too fast, and the engine is abnormal.
2. When the hot car is extinguished for more than ten minutes, it is not easy to start the car when it is started; sometimes the hot car will automatically turn off when it is running.
3. The air-conditioning cooling temperature is very cool when the car is cold, and the air-conditioning cooling effect of the hot car is not obvious; moreover, there is a large resonance noise in the air-conditioning system.
4. When the hot car is idling, the clutch of the air-conditioning compressor is frequently cut off and even disconnected, causing the hot air-conditioning air-conditioning to not cool.
5. Check if there is excessive dust between the condenser and the tank and thoroughly clean it with high-pressure gas to ensure that the tank and condenser have good heat dissipation.
Warm reminder: always pay attention to wipe the dust between the condenser and the tank.
In the hot car, check the temperature difference between the upper and lower water pipes of the water tank. If the temperature difference is too large, check the opening of the thermostat and whether the water pump has lost the rotation speed.
Reminder: The temperature difference between the upper and lower water pipes of the tank should not be too large.
After the hot car, check the water return of the return pipe on the top of the antifreeze storage tank. If the return water is not smooth or blocked, the water temperature will be too high.
