What Gear to Use When Passing Oncoming Traffic in a Narrow Road with Manual Transmission?

Manual transmission vehicles should use first or second gear when passing oncoming traffic in a narrow road. Precautions for passing oncoming traffic: Pay attention to traffic signals and signs when passing; reduce speed in advance and use low beams when visibility is poor; avoid emergency braking, sudden acceleration, or sharp steering during passing; avoid passing at obstacles; avoid passing at complex locations such as narrow bridges, narrow roads, tunnels, and sharp turns; avoid keeping high beams on during nighttime passing. Introduction to passing oncoming traffic: Passing oncoming traffic is a traffic term referring to vehicles traveling in opposite directions crossing paths at a certain point. Proper passing requires preparation in advance to avoid psychological panic and operational confusion during the maneuver.

Is an engine water temperature of 98 degrees Celsius normal?

An engine water temperature of 98 degrees Celsius is not normal. Generally, around 80 degrees Celsius is ideal. When water reaches 100 degrees Celsius, it turns into steam and creates pressure. At 98 degrees, it is prone to boiling over and can sometimes damage the radiator. Display of engine operating temperature: The water temperature gauge shows CH, where C represents 60 degrees Celsius. When the needle points to C, it means the water temperature has reached 60 degrees Celsius. The H red grid indicates a temperature of 110 degrees Celsius. The needle should ideally stay in the middle position. If the needle enters the red zone, the water temperature is too high, and the vehicle should be stopped and turned off immediately. Hazards of long-term high water temperature: Prolonged high water temperature can cause "boiling over," where the engine coolant boils, leading to radiator expansion and engine overheating damage.

What to Do When the Car Has Many Small Scratches?

Solutions for car body scratches include polishing, waxing for repair treatment, and using a touch-up pen. Below are the specific details: 1. Polishing: Use a polishing machine to gently polish the scratched area a few times, moving back and forth, then wipe clean with a small towel. The scratches will immediately appear much lighter. 2. Waxing for repair treatment: If it's just a very shallow scratch on the surface paint, you can use car wax to repair it by waxing in straight lines. After the scratch disappears, wipe with a finer compound and then apply wax. Choose high-quality wax, as poor-quality wax may not only be ineffective but could also worsen the paint damage. 3. Using a touch-up pen: Use a touch-up pen to eliminate the scratches. First, you need to know the color of your car's paint, then purchase a touch-up pen of the corresponding color. Shake well before use to ensure the paint is evenly mixed, then gently dab it onto the scratched area.

What is the standard size of a parallel parking space?

According to the relevant regulations of the "Specifications for the Setting of Motor Vehicle Driver Examination Sites and Their Facilities," the standard dimensions for a parallel parking space are as follows: For large vehicles, the parking space width is 4 meters, and the length ranges from 7 to 10 meters, depending on the vehicle model. For small vehicles, the parking space width is between 2.2 and 2.5 meters, with a length of 5 meters. A single-sided parking space is 5 meters wide, while a double-sided one is 6 meters, and for large vehicles, it is 8 meters. Below is an introduction to relevant parking techniques: 1. Observation: Before parking, check if the space can accommodate your vehicle and then consider parking. Forcing a vehicle into a smaller space is possible but requires multiple adjustments, which not only wastes time but also increases the risk of scratches. 2. Parking: Drive your car to the left front of the parking space, maintaining a horizontal distance of about 1 meter from the car in front. Adjust the distance, align the center of your car's right window with the center of the car in front, and then turn the steering wheel fully to the right to start reversing. 3. Adjustment: Finally, when the right rearview mirror overlaps with the B-pillar (the center point of the side of a large vehicle) of the car in front, the vehicle will be at approximately a 45-degree angle. At this point, straighten the wheels and slowly reverse. When the outer edge of the right rearview mirror aligns with the left rear taillight of the car in front, stop reversing and turn the steering wheel fully to the left to continue reversing slowly. If the car body appears slightly tilted, make gradual adjustments.

How to Solve the Sunroof Noise Issue in Mistra?

The solution to the sunroof noise issue in Mistra is to first check the sunroof sliding rail and add some lubricating oil. Below are the causes and solutions for sunroof noise: 1. Aging of the sealing rubber ring: The sunroof sealing rubber strip is exposed to rain or sunlight for a long time, making it prone to aging. Rubber conditioner can temporarily restore the performance of the rubber strip. Open the sunroof fully and spray the conditioner onto the sealing rubber strip. 2. Loose sunroof screws: Loose screws can cause ceiling noise and sunroof noise, and even pose a risk of the sunroof falling off. The solution is simple: locate the sunroof screws and tighten them. You can use a towel to remove dust, and regular maintenance is very important.

Why Does the Engine Make Loud Noises When Cold?

Engine cold start loud noise reasons are: Engine oil does not meet standards or excessive amount is added, increasing the stirring resistance of the crankshaft connecting rod; unsuitable oil viscosity; excessive engine carbon deposits, aggravating cylinder and piston wear; mixing different brands of engine oil; failure to change oil on time. Solutions for engine cold start loud noises are: Refer to the maintenance manual or driving environment and frequency to change oil regularly; use the same brand or same grade of engine oil; clean the three-way catalytic converter and throttle carbon deposits; add the gasoline grade recommended in the vehicle manual. Hazards of an excessively cold engine include: The temperature of the mixture entering the cylinder is too low, deteriorating the quality of the combustible mixture, making ignition difficult or combustion slow, leading to reduced engine power; unvaporized fuel washes away and dilutes the oil film on the surface of parts, accelerating part wear.
