What is the process of refrigerant charging?

Automobile air conditioning refrigerant charging process is: 1. System vacuuming, close the manual valves and high-low pressure manual valves on the pressure gauge; 2. Connect one end of the hose to the injection valve joint of the refrigerant tank; 3. Open the refrigerant tank, loosen the nut of the pressure gauge hose, let some gas escape and then close it; 4. Open the high-pressure side manual valve and invert the tank; 5. Inject the specified amount of liquid refrigerant, then close the refrigerant injection valve and high-pressure manual valve. The phenomena of excessive automobile air conditioning refrigerant are as follows: 1. The suction and discharge pressure of the air conditioning system is too high, and the equipment operating temperature is high; 2. The current value of the compressor power supply is significantly high, and prolonged operation will burn out electrical components; 3. The condenser is filled with refrigerant, the heat exchange area is small, and high-pressure protection occurs after the vehicle air conditioner is turned on.

What does the exclamation mark with a wavy line on the dashboard represent?

This is the tire pressure monitoring indicator light of the car. If the tire pressure monitoring indicator light stays on after the car completes its self-check, it indicates a fault in the tire pressure of the car, and it is necessary to promptly go to a 4S shop for inspection and repair to prevent tire blowouts and other failures. More details are as follows: 1. The indicator lights on the dashboard can help detect car problems in time. The dashboard indicator lights include the seat belt indicator light, front and rear fog light indicator lights, battery indicator light, fuel indicator light, etc. 2. When an indicator light for a certain system on the car's dashboard lights up, it means that the system has a fault, and the driver needs to be vigilant. 3. If a red indicator light appears, it indicates that the fault has affected the safe driving of the car, and it is necessary to go to a 4S shop for inspection and repair in time.

How to Repair Plastic Scratches on Car Bumper?

For minor scratches, prevention is key. It's advisable to protect the paint when it's still new, such as by applying a layer of mirror glaze on the car body surface. Use a polishing wheel with a polishing enhancer to remove the oxidation layer attached to the car's surface and smooth out fine scratches. This process only takes about 30 to 40 minutes. If the scratches on the car body have exposed the primer, a local touch-up paint treatment is necessary.

How far can you drive when the fuel gauge is in the red zone?

According to standard fuel consumption calculations, when the fuel gauge light comes on (i.e., the needle enters the red zone), the car can typically travel approximately 50–90 kilometers. Driving within 20 kilometers after the fuel light turns on is generally safe, but beyond this range, caution is advised. It is best to prepare gasoline in advance. Additional information: 1. When the fuel warning light illuminates, it indicates that the fuel level has dropped below the fuel pump. The exposed fuel pump begins to overheat due to the lack of fuel for cooling. Continuing to drive at this point further exposes the fuel pump, worsening the overheating. Many drivers continue driving even after the warning light comes on (sometimes until the fuel runs out), which is not advisable. 2. When the fuel tank's yellow warning light appears, it is recommended to refuel at the nearest gas station promptly. This not only prevents the risk of running out of fuel mid-journey but also avoids potential damage to the vehicle. When the fuel level falls below the fuel pump, the pump lacks sufficient fuel for cooling. The more the fuel is depleted, the more severe the overheating becomes, ultimately shortening the fuel pump's lifespan.

How to Change a Flat Tire?

When removing the tire, do not immediately jack up the car. First, use the lug wrench to loosen each wheel bolt one by one. Align the spare tire with the wheel bolt holes, use your leg or foot to brace the spare tire to prevent movement, and then slightly tighten the bolts in a diagonal pattern.

What is the recommended RPM range for a new car?

During the break-in period for domestic new cars, it is advisable to maintain a speed between 40~70 km/h, while imported vehicles should generally stay within 100 km/h. The recommended RPM range is 000~4000 rpm. Avoid long-distance driving during this period as prolonged engine operation may accelerate component wear. Below are precautions for new car break-in: 1. Avoid overloading: Keep payload below 75% of rated capacity for domestic vehicles (90% for imports). Overloading stresses engine, transmission, drivetrain, and suspension components. 2. Choose smooth road surfaces to minimize vibration and avoid sudden braking or collisions. 3. Use fuel with octane ratings meeting manufacturer specifications. Do not add anti-wear additives that might compromise proper break-in. 4. Properly adjust ignition and fuel systems to optimize fuel economy during break-in, especially when speed limiters affect vacuum economizer performance. 5. Practice gentle driving techniques: depress clutch and accelerator pedals smoothly during startup, then warm up engine at low speed until reaching 50°C~60°C.
