After the chassis is scraped, it is necessary to inspect the chassis. As long as there is no fluid leakage or deformation of mechanical parts, there should be no problem. The chassis is one of the more vulnerable parts of a car. Applying chassis armor can bring the following benefits to the owner: 1. Anti-corrosion for the chassis. Washing water can remain on the bottom of the car, which can become a potential corrosion factor over time; 2. Protection against stone impacts; 3. Vibration damping. The engine and wheels are fixed to the car chassis, and the vibrations of these components can resonate with the chassis at certain frequencies. Bottom protection can eliminate some of this resonance; 4. Heat insulation; 5. Noise reduction. When driving on highways, the friction noise between the wheels and the road surface is proportional to the speed. A well-protected bottom can significantly reduce interior noise; 6. Protection against bottoming out. The thickness of the bottom sealing material can reach 1.5 to 2.5 mm. When the bottom is scraped by road protrusions, the chassis sealing can mitigate the damage caused by the protrusions to the chassis.

Last week, I accidentally scraped the undercarriage of my car, and I was a bit worried since the undercarriage protects the engine and other critical components. If it's just a minor scratch, like a small scrape on the rustproof paint, it's usually not a big deal—just that it might rust over time and needs timely treatment. However, if the scrape is deep, it could damage the fuel tank or oil pan, leading to oil or fuel leaks, which is dangerous, so be cautious of ignition sources. I usually check the extent of the damage with my phone's flashlight first, then sniff for any fuel odor to ensure safety before driving to the repair shop. I recommend driving slowly over potholes and installing an undercarriage guard as a buffer to avoid constant worries affecting the driving experience.

Is a Car Tire Pressure of 150 Normal?

A car tire pressure of 150 kPa is not normal. According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: Should not exceed 3.5 bar. Tire pressure reset method: First, turn on the ignition, then press and hold the tire pressure monitoring reset button until you hear a "beep" sound before releasing it. The tire pressure monitoring system will then store the current normal tire pressure data, automatically clear the previous data, and finally, the warning light on the dashboard will turn off, indicating the tire pressure reset is complete. There are generally three reasons for abnormal tire pressure: Abnormal tire pressure: Usually, the system will alert when the pressure is below 1.8 bar or above 3.0 bar. In this case, tire inspection and pressure adjustment are required. Tire pressure monitoring not reset: After inflating the tires, if the tire pressure is not reset in time, the tire pressure monitoring system will still record the previous data, causing the tire pressure monitoring indicator light to turn on. Simply performing a tire pressure reset will resolve this issue. Damaged tire pressure sensor: The tire pressure sensor, which is used to monitor tire pressure, is installed inside the tire and connected to the tire inflation valve. If the sensor is damaged during driving, it will also cause the tire pressure warning light to turn on. For sensor damage, the only solution is to replace it with a new one.

How to Confirm ETC is Working Properly?

To confirm the ETC is working properly, remove the ETC bank card and then reinsert it into the electronic tag. After hearing a beep sound, if the electronic tag screen displays 'Debit Card' or shows the amount, then the ETC is functioning normally. If inserting the ETC card into the electronic tag results in messages like 'Electronic Tag Invalid' or 'No Card Inserted,' it indicates an issue with the electronic tag, requiring reactivation and reinstallation at an ETC service outlet. ETC, short for Electronic Toll Collection, is an electronic system that enables vehicles to pass through toll stations without stopping. It identifies vehicles, records information, and automatically deducts the corresponding funds from a pre-linked IC card or bank account. It is an internationally promoted electronic toll collection system for roads, bridges, and tunnels.

How to Solve Car Audio Problems?

1. If the car suddenly has no sound, first check if the CD player's power supply is normal. As long as there is power, the indicator light should be on, and the CD player compartment should open and close normally. If there is no power, check the power supply, including the fuse box and wiring. 2. If the car audio has been modified, check the modified fuse or specifically inspect whether the audio output line has come loose. 3. If the audio suddenly stops working and it does not affect the car's operation, you can visit a nearby professional repair shop. Car audio is a radio and playback device installed to alleviate the boredom of drivers and passengers during travel. The earliest used was the car AM radio, followed by AM/FM radios and tape players. Nowadays, car audio has reached a high standard in terms of sound quality, operation, and shock resistance, capable of handling the bumps on rough roads while ensuring stable performance and perfect sound quality.

How to Follow a Car Slowly for Beginners?

Key points for beginners to follow a car slowly are as follows: 1. Leave space for rolling back on uphill sections: When driving on uphill roads or overpasses and encountering stop-and-go traffic, always leave enough distance to prevent the car in front from rolling back when starting. Pay special attention to overloaded large trucks—it's best not to follow them and to leave a longer-than-normal distance to prevent them from rolling backward. 2. Determine the following distance based on speed: While driving, the faster the speed, the greater the distance between vehicles should be. Generally, the vehicle spacing should roughly equal the speed in kilometers per hour. For example, at 70 km/h, the spacing should be more than 70 meters. If the road ahead is clear and you can observe the traffic conditions well, you can slightly reduce the distance to a point where other vehicles can't easily cut in. 3. Follow slowly in crowded areas: During long-distance driving, maintain a good rhythm and take breaks. When passing through towns, especially crowded roads, it's best to follow a large vehicle slowly and relax. In heavy fog with poor visibility, if there's a car ahead, follow it and avoid overtaking just because it's moving slowly. 4. Increase spacing when following a large vehicle: Small cars following large vehicles are more affected by the leading car, so increase the spacing appropriately and closely monitor the leading car's movements. When following a bus in busy urban areas, be patient. If overtaking is necessary, observe the situation from a distance to ensure no sudden appearance of pedestrians or cyclists during the maneuver. 5. Stay calm while following: During following, if pedestrians or non-motorized vehicles cut in, remain patient and avoid frustration. Especially at crosswalks, actively yield to pedestrians to demonstrate good professional ethics.

How Soon Can a New Car Go on the Highway?

New cars can go on the highway at any time. Newly purchased cars have a break-in period, during which the car can drive at high speeds as long as the engine is not operated at excessively high RPMs. Running the engine at high RPMs during the break-in period can increase engine wear. When driving on the highway, the following points should be noted: 1. Maintain a safe distance from the vehicle in front and avoid getting too close; 2. Drive in the appropriate lane—faster vehicles should stay in the fast lane, while slower ones should use the slow lane; 3. In case of an emergency on the highway, park the vehicle in the emergency lane, turn on the hazard warning lights, and place a warning sign 150 meters behind the car; 4. Private vehicles are prohibited from using the emergency lane for driving. Maintaining a safe distance while driving is the best preventive measure to effectively avoid traffic accidents on the highway.
