Is There Any Impact If the Engine Is Washed with a Water Gun?

It is not recommended to use water to wash the engine compartment, as it may cause certain damages and safety hazards. Here are the relevant details: You can use cleaning agents: If there is oil sludge on the engine's exterior, you can use cleaning agents for washing, then dry it with an air gun or a cloth. Do not use water to wash the engine, as the engine contains many electrical components and cable connectors. Each of these connectors has a sealing ring that provides simple waterproofing. Using a car water gun for washing risks breaking the sealing rings of the connectors, leading to water ingress. Precautions: Additionally, if there is oil sludge on the engine casing, it is not easy to clean it thoroughly with water. Lastly, it is important to note that when cleaning the engine, always wait until the engine temperature returns to normal. Cleaning the engine while it is still hot can easily cause damage to engine components or reduce their lifespan.

Does crossing the stop line just as the light turns red count as running a red light?

If the front of the vehicle crosses the stop line when the red light turns on and does not move further, it is not considered a violation. Below is relevant information about vehicles crossing the stop line when the red light turns on: 1. When the red light is on, the entire vehicle crosses the stop line: If the entire vehicle crosses the stop line and does not continue moving, it is not considered running a red light. However, this situation is classified as crossing the stop line and stopping. According to Article 4, Clause 5 of the 'Scoring Standards for Road Traffic Violations,' 'failing to drive or park as required at intersections results in a 2-point deduction.' 2. When the red light is on, crossing the stop line and then reversing: Although this is not penalized as running a red light, motor vehicles are not allowed to reverse at railway crossings, intersections, one-way roads, bridges, sharp curves, steep slopes, or tunnels. If reversing is performed illegally, a warning or a fine ranging from 20 to 200 yuan may be imposed. If there is no immediate danger, it is best to stop and not move.

Is It Advisable to Purchase a Domestic Car That Has Been in Stock for Over 6 Months?

Yes, it is still advisable because, although the manufacturing date exceeds 6 months, the vehicle is generally still in a new condition. However, the following points should be noted when purchasing: Vehicle Price: When negotiating the price with the salesperson based on the duration the car has been in stock, this factor should be appropriately considered. This is because, during future used car transactions, most used car appraisers will reference the manufacturing date for valuation. Engine Oil Condition: Many car manufacturers specify the maintenance cycle for engine oil and oil filters based on two parameters: the vehicle's mileage and, more critically, the duration of oil usage. Tire Condition: If the stock car remains stationary for extended periods and the tires are not maintained at high pressure, it can lead to deformation of the tire rubber, posing a potential risk of vehicle body vibration.

Will points be deducted if a child stands through the car sunroof?

Points will be deducted if a child stands through the car sunroof, usually 2 points and a fine. It is recommended not to let children stand through the sunroof while driving, as it is not only illegal but also very dangerous, posing a risk to personal safety. Below are the functions of a panoramic sunroof: Air circulation: It can be used to quickly circulate fresh air and remove stale air from the car. When the car is not in use, it is usually parked in a closed state. Over time, some decorations and devices inside the car will start releasing toxic substances. Opening the sunroof after using the car allows for air circulation between the inside and outside, making the entire driving experience start smoothly. Rapid cooling: August is the hottest time of the year. After being parked under the sun for several hours, the temperature inside the car can rise to unbearable levels. In summer, when you first enter the car, it can feel extremely stuffy. Even with the air conditioning on, it takes a long time for the heat to dissipate. Opening the panoramic sunroof cools the car faster.

Should the Transmission Oil Seal Leakage Be Repaired?

Transmission oil seal leakage requires replacement if the leak is significant, while minor leaks can be repaired. Causes of leakage: Pipeline damage causes oil to leak from the damaged area during circulation; at the connection between the transmission and the engine, the sealing gasket may be damaged, or the fastening bolts may be loose, leading to an enlarged connection gap and reduced sealing effectiveness, resulting in oil leakage from the gap. Treatment methods: Improve the vent cap and inspection hole cover plate by opening an oil return groove inclined inward toward the machine at the center of the lower bearing seat, and also opening a notch at the straight edge of the end cover, aligning the notch with the oil return groove, allowing excess lubricating oil to flow back into the oil pool through the notch and oil return groove; improve the shaft seal structure by using new sealing materials; during transmission maintenance, strictly follow the process procedures, ensuring the oil seal is not installed backward, the lip is not damaged, the outer edge is not deformed, the spring does not fall off, the mating surface is thoroughly cleaned, the sealant is evenly applied, and the oil level does not exceed the oil dipstick mark.
