Replacing the engine wiring harness does not require removing the engine. If the engine wiring harness is damaged, it can be directly replaced. A faulty engine wiring harness can cause inaccurate signals, which may prevent the vehicle from starting and could even lead to a fire. The wiring harness is the main network of the car's electrical circuits; without it, the car's electrical system would not function. Methods for inspecting the car wiring harness: 1. Visual Inspection Method: When a part of the car's electrical system fails, abnormal phenomena such as smoke, sparks, unusual noises, a burnt smell, or high temperatures may occur. 2. Instrumentation Inspection Method: This involves using comprehensive fault diagnostic tools, multimeters, oscilloscopes, current clamps, and other instruments to diagnose faults in the car's electrical circuits.

What is the speed limit on the Suiman Expressway?

The speed limit on the Suiman Expressway is 120km per hour. This expressway runs from Suifenhe City to Manzhouli City. More details are as follows: 1. Starting and ending points: Different expressways have different numbers. If you are unsure about the starting and ending points of an expressway, you can simply check its number. 2. Expressway speed limits: Generally, the speed limit on expressways is 120 kilometers per hour. When driving on expressways, do not exceed the speed limit, as it can be very dangerous. Expressways also have minimum speed limits. Driving below the minimum speed limit on an expressway is also very dangerous and can lead to serious rear-end collisions. When driving on expressways at night, you can use high beams because there are separation facilities in the middle of the expressway, so using high beams will not affect the visibility of drivers in oncoming lanes.

How Long After Drinking Five Bottles of Beer Can You Drive?

It depends on the physical condition of the drinker. Generally, consuming one or two bottles of beer, about 1-2 taels of 12-degree red wine, or half a tael of 50-degree liquor can already meet the standard for drunk driving. Since the metabolism of alcohol in the human body is limited, typically only 10 to 15 grams of alcohol can be metabolized per hour. Therefore, after drinking one bottle of beer or half a tael of liquor, it is best to wait at least 10 hours before driving. If you consume two bottles of beer or 3 taels of low-alcohol liquor, it is advisable to wait a full day before driving. If the alcohol content is higher or the quantity consumed is larger, you should wait even longer before driving. More details are as follows: 1. Factors affecting metabolism: This timeframe is not absolute, as the rate of alcohol metabolism in the body varies from person to person and can even differ for the same individual under different circumstances or environments. 2. Typical elimination time: Alcohol usually takes 10-20 hours to be eliminated from the body. Sometimes, people drink at night, sleep, and feel fine the next morning, but they may still be caught for drunk driving because the alcohol hasn’t been fully cleared from their system. Even if there are no noticeable physical effects, alcohol may still be present in the body. Therefore, waiting 10-20 hours after drinking before driving is scientifically advisable.

Are Cars Lightning-Proof?

Cars are not equipped with lightning rods and do not provide lightning protection. Here is some information about lightning protection: 1. Lightning protection measures: Vehicles generally do not have specially installed lightning rods, but the metal body of the car acts as a shield. Even if lightning strikes the car, it will not harm the occupants. The interior of the car is an ideal place to avoid lightning strikes. The tires of the car have excellent insulating properties. If lightning strikes the car and charges it, the current cannot form a circuit to the ground, thus causing no harm. 2. Conductive materials: The tires may have water or other conductive substances on them, and some may be equipped with anti-static grounding wires. When lightning strikes the car and charges it, the current tends to flow along the metal surface, posing no danger to people. The current is conducted through the car's surface to the tires, which may have water or other conductive substances.

Will stopping on the crosswalk at a red light result in penalty points?

Stopping a vehicle on the crosswalk at a red light will result in penalty points. Since stopping on the crosswalk is considered over-the-line parking, it incurs a 2-point deduction. Here are precautions for crossing traffic lights: Drive according to signals: Follow the green and red light instructions; do not run red lights or violate traffic rules. Check left and right: Even when driving according to the signals, always look left and right to avoid collisions with vehicles violating traffic rules, which could lead to accidents. Wait orderly: During a red light, wait in the designated waiting area and avoid vehicle turning lanes. Watch for vehicles ahead: Pay attention to the vehicles in front; proceed orderly through the traffic light only after the vehicle ahead starts moving to prevent congestion and traffic jams.

How to Quickly Remove Fog Inside the Car on Rainy Days?

To remove fog inside the car on rainy days, you can turn on the air conditioning with cold air. Here are some precautions for driving in the rain: Reduce overtaking: Because the steering wheel becomes more sensitive and harder to control in the rain, drivers should stay within their designated lanes and minimize lane changes. It's best to avoid overtaking on narrow roads to prevent skidding. Simply follow the vehicle ahead and avoid showing off. Check the condition of the wipers: Rainy days already result in poor visibility, and rain hitting the windshield can make it worse. If the wipers are faulty, it will be impossible to clear the water mist from the windshield, significantly affecting driving safety. Therefore, always check the wipers in advance.
