What to Do When Water Leaks into the Car Trunk?

Here are the methods to deal with water leakage in the car trunk: 1. Regularly clean the sunroof and trunk: During regular car washes, the sunroof and trunk are often overlooked. It is necessary to clean the drainage channels of the sunroof and trunk, wiping away dust and mud from both sides of the drainage channels. Use a slightly stiff wire or brush to unclog the drainage holes, then pour some detergent water for rinsing. 2. Lubricate and clean the sealing strips: Use a damp cloth to clean the sealing strips to prevent fine sand from sticking to them. Talcum powder or baby powder can be used to absorb excess grease and moisture from the sealing strips.

How Long Should You Warm Up Your Car in Winter?

Warming up your car for 1 to 2 minutes in winter is appropriate, allowing the engine coolant to reach normal operating temperature before driving. The reasons for warming up your car in winter and the impacts of not doing so are as follows: Reasons for warming up your car in winter: After prolonged parking, the engine oil flows back into the oil pan at the bottom of the engine; before the engine reaches its operating temperature, the fuel supply system cannot effectively vaporize gasoline completely due to low temperature; in cold conditions, gear oil flows to the lower part of the transmission. Impacts of not warming up your car in winter: Not warming up your car in winter can cause wear and tear to the engine, transmission, and various engine components, leading to reduced lifespan; it increases fuel consumption and makes the engine more prone to carbon buildup inside.

What is the difference between disc brakes and drum brakes?

Drum brakes and disc brakes differ in braking methods, composition, etc. The specific differences are as follows: Different braking methods: Drum brakes use hydraulic pressure to push the brake shoes against the inner edge of the brake drum, generating friction to inhibit tire rotation and achieve braking. Disc brakes have flat brake pads on both sides of the brake disc. When hydraulic pressure from the master cylinder is delivered to the wheel cylinder, the brake pads clamp onto the brake disc to achieve braking. Different compositions: Drum brakes consist of a brake backing plate, wheel cylinder, brake shoes, related linkages, springs, brake pins, and the brake drum. Disc brakes are hydraulically controlled and mainly comprise a brake disc, wheel cylinder, brake caliper, and hydraulic lines. Different advantages and disadvantages: Drum brakes have good self-braking effects and lower manufacturing costs, but their braking system responds slower, the pedal force is harder to control, they are less suitable for high-frequency braking, and they are harder to repair. Disc brakes offer better heat dissipation, simpler construction for easier maintenance, but the brake pads wear out faster, requiring more frequent replacement.

What are the techniques for judging following distance?

During the driving process, it is necessary for us to accurately judge the distance between vehicles. The following is a detailed introduction to methods for judging vehicle distance: 1. Using the rearview mirror to judge the distance of the following vehicle: According to the physical principle that objects appear larger when closer and smaller when farther away, when the image of the following vehicle occupies one-third of the rearview mirror, the distance should be 12 meters; when the image occupies half of the rearview mirror, the distance is 9 meters; when the image occupies the entire rearview mirror, the distance is 3 meters. 2. Judging the distance to the vehicle in front during urban driving: When we can see the rear bumper of the vehicle ahead from the driver's seat, the distance is approximately one meter; when we see the lower edge of the bumper, the distance is about two meters; when we see the rear tires of the vehicle ahead, the distance is about 3 meters. 3. Using roadside reference objects for judgment: When driving on highways, because the following distance is larger, the above methods cannot be used. At this time, fixed roadside objects such as lamp posts can be used as references to judge the distance and help control the following distance. Generally, the distance between two adjacent lamp posts is equal and 50 meters, and the distance of three lamp posts is approximately equivalent to the normal following distance on highways, which is 100 meters. When observing, we should pay special attention: if the time it takes for the vehicle ahead to travel from one lamp post to the next decreases, it indicates that the vehicle is moving quickly, and we can accelerate accordingly. Conversely, if the time increases, the speed is slower, and we should appropriately reduce speed.

Is it illegal to modify the steering wheel?

Modifying the steering wheel is not illegal. However, it may affect the annual inspection. It is advisable to switch it back during the annual inspection. The relevant information about modifying the steering wheel is as follows: Illegal car modifications: Modifying the car engine has always been considered an illegal act. Engine modifications might provide sufficient power, but they can significantly impact safety and even affect the engine's lifespan, among other issues. If you are pursuing speed, it is better to choose a speed-oriented car when purchasing, rather than modifying it afterward. Precautions for modifying the steering wheel: First, modifying a racing steering wheel does not involve altering the vehicle's power or structure, so it is legally permitted. Secondly, changing to a racing steering wheel does not require registration, but it is best to switch back to the original steering wheel during the annual inspection. From a safety perspective, it is not recommended to modify to a racing steering wheel, as most racing steering wheels do not have airbags, which compromises safety in the event of a collision.

Can You Turn Right at a Red Light Intersection?

An analysis based on the current traffic light configuration is required to make a judgment. The specific determination methods are as follows: Circular traffic lights: This type of traffic light does not separately restrict left or right turns; as long as the light is green, you can turn. This style of traffic light only controls whether vehicles at the intersection should stop or proceed, without restricting how to turn after the light turns green. Arrow traffic lights: If a red right arrow appears, it indicates that turning right is currently prohibited, and you must wait for it to turn green before turning right. Additionally, special circumstances should still be noted, such as whether there are other traffic restriction signs at the intersection, requiring a comprehensive assessment of the current road conditions.
