Flood-damaged cars refer to vehicles that, due to heavy rain, were not promptly moved by their owners from underground garages or low-lying areas and were submerged in water for an extended period. Below is an introduction to flood-damaged cars: 1. Identification: The wiring in the engine compartment of a flood-damaged car is often covered in mud, which cannot be completely cleaned. This is one of the most obvious methods to identify a flood-damaged car. 2. Interior Impact: The leather materials on the dashboard will darken after being submerged, with some areas appearing darker than others. A careful sniff may also reveal a musty odor. 3. Operational Impact: For vehicles that have been submerged (without ignition), the most significant issue might be electrical problems. Electrical issues cannot be fully repaired, and even after repairs, the circuits may malfunction within as little as 3 months or as long as a year or more. Specific symptoms include the illumination of warning lights without any actual faults, headlights turning on unexpectedly, and other power-related issues.

I've climbed my way up from the used car dealership trenches, and I've seen way too many flood-damaged cars. Simply put, these are vehicles that have been completely submerged in water—if the water level was above half the tire height, it's almost guaranteed. The real nightmare with these cars lies in the hidden areas: electrical connectors rusted like honeycombs, ECU (engine control unit) acting up months after the flood, and that unmistakable sewer smell when you turn on the AC. The engine is a ticking time bomb—even if it starts after water exposure, water mixed with oil in the crankcase will lead to cylinder scoring within a few thousand kilometers. When I inspect cars, I always peel back the door seals to check the welds, lift the carpet to feel for mold on the floorboard, and my ultimate trick—pulling out the seatbelt to check for water stains at the base. These are telltale signs that even professional detailing can't erase.

How Many Amps is 12V?

The working current of a 12V battery depends on its model, i.e., capacity. It is usually marked on the casing. The larger the working current, the shorter the duration. For example, a 20Ah battery discharging at 2 amps can last for 10 hours before needing a recharge. The instantaneous maximum current can reach 70 to 100 amps or even higher. However, it's important to note that excessively high currents can cause problems, including battery explosion. When a battery is severely depleted, it should not be charged using the car's alternator; instead, a portable charger should be used. A 12V battery cannot be equated to a specific milliampere value. Batteries are typically described by two data points: voltage and capacity, e.g., 12V65AH. This is read as '12 volts 65 ampere-hours,' meaning the battery has a voltage of 12V and a capacity of 65 ampere-hours. Milliampere readings represent instantaneous current and do not indicate the battery's capacity. Signs that a battery is fully charged: A large number of bubbles are generated inside the battery, creating a boiling effect. The terminal voltage rises to its maximum and does not increase further within two hours. The electrolyte level rises to its highest point and does not increase further within two hours.

Can you cross a yellow dashed line for overtaking or turning?

You can cross a yellow dashed line for overtaking or turning. Introduction to road yellow lines: Yellow lines are used to separate lanes of traffic moving in opposite directions, typically painted in the center of the road, acting like a divider that splits the road into two directions. Whether it's a single or double yellow line, if it's solid, crossing is strictly prohibited. Under normal driving conditions, you should not cross the line. Whether it's a single or double yellow line, if it's dashed, you can overtake or make a U-turn when it's safe to do so. Single yellow lines are generally used on roads with up to four lanes (including bicycle lanes), while double yellow lines are used on wider roads. Single yellow line is solid: Crossing is strictly prohibited, including actions like overtaking, turning, or making a U-turn. Under normal driving conditions, you should not cross the line. Driving over a solid line is not allowed, and making a U-turn is considered a violation of the no-crossing rule, resulting in a 3-point penalty. Single yellow line is dashed: You can overtake or make a U-turn when it's safe to do so. A single yellow line serves as a center divider to separate traffic directions. A yellow dashed line allows temporary crossing for lane changes or overtaking during driving, while a solid line should be treated like a wall—absolutely no crossing. Roads with four or more lanes in both directions are marked with double yellow lines, while those with fewer lanes use single yellow lines.

Are All Cars Over 10 Years Old Fuel Inefficient?

Whether cars over 10 years old are fuel inefficient depends on specific circumstances. There are many factors affecting a car's fuel consumption, including external and internal factors. External factors: Driving habits, road conditions, vehicle load, tire pressure, and other factors can all influence a car's fuel consumption. Internal factors: What truly affects a vehicle's fuel consumption is how many strokes the engine makes within a specified time and distance. Strokes refer to the engine's RPM. Therefore, only when both displacement and RPM are low will the car's fuel consumption be lower. These factors are interrelated. Solutions for high fuel consumption: First, check the tires. If the tire pressure is insufficient, fuel consumption will increase. If the tire pressure is normal, inspect the tire wear. Severe tire wear can cause slipping, which also increases fuel consumption. Next, examine the engine. If there is excessive carbon buildup in the engine in a short period, it may be due to using substandard fuel. Add a certain amount of cleaner when refueling. If the effect is not noticeable, it indicates significant carbon buildup in the engine, which requires cleaning by a 4S shop or repair shop. Finally, if the oxygen sensor is damaged, it will disrupt the air-fuel ratio in the engine, leading to abnormally high fuel consumption. Replace the oxygen sensor as soon as possible.

Do I Need to Drive the Car to Get a Replacement Key?

You definitely need to bring the car when getting a replacement car key. The new key must be reprogrammed with the vehicle, as the anti-theft chip inside the car requires computer synchronization with the vehicle. Additionally, you should bring both keys with you. Types of Car Keys: Currently, car keys are divided into two types: mechanical keys and remote keys. Different car models have different keys and chips, and the prices vary accordingly. If you seek help from a 4S service station, you'll need to have the car towed there first, as only the dealership has the equipment to open the car door or program a new key. If you need to open the car door to make a new key, be sure to bring relevant documents to prove you are the owner—this helps avoid unnecessary trouble. The cost of getting a key from a dealership is relatively higher than at an outside repair shop, but the security is highly reliable. Spare Key: Generally, cars now come with two keys: one for regular use and the other as a spare. If the primary key is lost, the spare key can come in handy. Therefore, it's crucial to remember that the spare key should never be left inside the car—always keep it in a safe place at home. Otherwise, if the primary key is lost and the spare is still inside the car, you'll have to call a locksmith. Professional Locksmith Services: If the vehicle is far from the spare key or the spare key is also missing, you’ll need to hire a professional locksmith to unlock the car. Typically, you'll need to provide relevant documents, such as your ID card or vehicle registration certificate.
