Car trunk leakage is caused by improper sealing of the weatherstrip or damage and deformation of the trunk. Here is a detailed introduction to car trunk leakage: 1. The waterproofing in various parts of a car is ensured by weatherstrips, which are made of rubber material. This rubber material inherently possesses certain strength and hardness, generally preventing deformation during use. However, the weatherstrips on a car are consumable items. Prolonged exposure to external air leads to aging, and frequent use can also cause wear and tear to some extent. Once the weatherstrip is damaged, the car will leak. 2. The design of the car trunk follows certain rules. If the shape of the trunk is compromised, rainwater intrusion can lead to severe leakage. There is a rubber drain plug in the area where the spare tire is placed in the trunk. Removing it allows the water in the trunk to drain out. For aged weatherstrips, car owners can purchase and replace them themselves or have them replaced at an auto repair shop. 3. Hazards of trunk water ingress: Water in the trunk can easily cause rust, and in severe cases, perforation may occur. The spare tire compartment in the trunk is relatively low, making it prone to water accumulation. If not drained promptly, it can easily lead to mold growth in the car's interior.

What Are the Consequences of Excessive Engine Oil Temperature?

The consequences of excessive engine oil temperature include harming the engine, causing localized overheating, and reducing oil viscosity. Below are the specific details: 1. Harm to the engine: When the engine oil temperature is too high, it will affect the normal operation of the engine and cause certain damage. The water temperature mainly indicates the thermal condition of the engine combustion and high-temperature components such as pistons and cylinder walls. 2. Localized overheating: Due to poor heat conduction, localized overheating can occur, especially in parts far from the radiator in the cooling water circulation direction and structurally weak areas, leading to localized deformation, cracks, and burn damage. 3. Low oil viscosity: This results in reduced oil viscosity, oil burn-off, destruction of the oil film in the engine's lubrication points, accelerated wear of components, and in severe cases, can cause bearing seizure or cylinder scoring.

How many points are deducted for speeding at 150 km/h on the highway?

Speeding at 150 km/h on the highway generally results in a deduction of three points. Below are the specific details regarding speeding on highways: 1. Relevant regulations: Speeding less than 50% on highways is penalized according to Article 90, involving a fine and 3 points. Speeding over 50% results in a fine, 6 points, and revocation of the motor vehicle driving license. 2. Violations incurring 6 points: (1) Driving medium-sized or larger passenger or cargo vehicles, school buses, or hazardous material transport vehicles on highways or urban expressways at speeds exceeding the limit by less than 20%. (2) Driving the aforementioned vehicles on roads other than highways or urban expressways, or driving other motor vehicles at speeds exceeding the limit by 20% but less than 50%.

What is the Difference Between a Spare Tire and a Regular Tire?

The differences between a spare tire and a regular tire are: 1. Different usage scenarios: Spare tires are used when a regular tire has a flat or is deflated; regular tires are used during normal driving. 2. Different usage durations: Spare tires serve as temporary replacements and should not be used for extended periods; regular tires are used under normal conditions and can be used for long durations. 3. Different speed requirements: Spare tires are intended for non-driving wheels and should not exceed speeds of 80 kilometers per hour; regular tires have no special speed restrictions. Car tires are crucial components of a vehicle, directly contacting the road surface and working with the car's suspension to absorb shocks during driving, ensuring good ride comfort and smooth operation.

What Causes Car Window Glass to Not Roll Up?

The reasons why car window glass cannot roll up: 1. The window switch is faulty; 2. The window regulator screws may be loose, which is often accompanied by vibration and abnormal noise from the glass; 3. The window regulator is stuck, causing all window regulators to stop working. When the car window glass fails to roll up, the owner can initialize the window switch. The initialization method generally involves turning on the ignition switch, pulling and holding the window switch upward until the glass reaches the top, then continuing to hold for more than 3 seconds. Release the switch and immediately press and hold it downward until the glass reaches the bottom and hold for more than 3 seconds. Then, pull and hold the switch upward again until the glass reaches the top and continue to hold for more than 3 seconds. The initialization is then complete.

How to perform emergency braking in a vehicle equipped with ABS system?

To perform emergency braking in a vehicle equipped with ABS system, firmly press the brake pedal. Below are some introductions about ABS: 1. The Anti-lock Braking System is abbreviated as ABS. 2. Its function is to automatically control the braking force during vehicle braking, preventing the wheels from locking up and keeping them in a rolling-sliding state to ensure maximum adhesion between the wheels and the road surface. Extended content: When the braking system enters the anti-lock state, the following situations may occur: 1. The ABS motor operates. 2. The brake pedal vibrates. 3. In the final stage of braking, the brake pedal may slightly or slowly descend.
