Should a New Car Be Driven at High Speed?

New cars can be driven at high speeds, which is primarily done to remove carbon deposits from the engine. During the break-in period, prolonged low-speed driving can easily lead to carbon buildup in the engine. This practice is not only applicable to new cars but also to vehicles frequently driven in congested areas. However, avoid exceeding 200 km/h on highways; maintaining a speed between 100 to 120 km/h is sufficient. After the break-in period, it is advisable to take the new car on the highway for a high-speed run. The purpose is to allow the new pistons and camshaft inside the engine to experience their first rapid operation, ensuring better contact between them. Driving at high speeds also enables the transmission gears to rotate quickly, promoting smoother meshing between the new gears. This practice helps the car achieve better power performance and smoother gear shifts in future driving.

What Causes Excessive Noise Inside the Car?

Excessive noise inside the car can be attributed to: 1. Engine noise; 2. Tire noise; 3. Wind noise; 4. Chassis noise. The solution to car noise is to identify the source of the noise and then address it accordingly. Engine noise and chassis noise can be reduced by installing soundproofing materials; tire noise can be mitigated by switching to tires with better noise reduction performance. Taking engine noise as an example, engine abnormal sounds can be categorized into cold-start abnormal sounds and hot-engine abnormal sounds. Cold-start abnormal sounds refer to the noises coming from the engine compartment when starting the car, which disappear after the engine warms up. This type of noise is often caused by the car being parked for an extended period without normal operation, leading to a rattling sound. There are more reasons for hot-engine abnormal sounds. If you notice that the engine noise is gradually increasing, it is advisable to promptly visit a repair shop for inspection.

How to Protect a Sedan Parked Outdoors in Snowy Weather?

It is best to cover the car with a car cover during long-term parking. If a car cover is not available, you can choose to use a large dry towel to cover the windows and headlights. In low-temperature environments, if the handbrake is engaged, the brake pads can easily stick to the brake discs, which may damage the braking system when starting the car the next day. Remember to replace the vehicle's coolant with automotive-specific antifreeze; otherwise, components such as the engine block, cylinder head, and radiator are prone to cracking due to expansion. The vehicle should avoid being parked in areas with standing water, as the water can freeze the wheels directly, leading to potential tire damage.

What to Do When a Car Tire Gets Punctured and Loses Air?

If a car tire is punctured by a nail and the air leakage is slow, you can drive at low speed to the nearest repair shop for inspection. Do not ignore it as it may affect safety. However, if the air leakage is severe, do not continue driving. Instead, replace it with the spare tire or call for roadside assistance. Otherwise, the tire may be excessively damaged from continued driving. If the tire is severely leaking air, promptly park the vehicle in a safe location and call for assistance or replace it with the spare tire to drive to the nearest repair shop for servicing. If the tire is punctured but not leaking air, you can continue using it temporarily. However, do not leave it unattended for too long—take it to a repair shop as soon as possible.
