Fully submerged cars are not easy to repair and require significant time and money. The hazards of water-damaged vehicles include the following: Impact on the interior: Prolonged soaking can cause materials like carpets and seats to deform, become rough, produce odors, and foster bacterial growth. Moisture in the wiring harness under the carpet can lead to short circuits due to dampness. It is best to replace all soaked components to avoid long-term damage. Impact on door panels: The sound insulation material inside door panels needs replacement after water exposure. The four-wheel bearings must also be replaced because their seals contain lubricating oil, which can corrode and deteriorate, losing its lubricating function and compromising driving safety.

Fully submerged cars are really difficult to repair. With years of car repair experience, when water completely submerges the vehicle body, it can enter the engine block, potentially causing the engine to seize and fail to operate; electronic control systems like the ECU or computer modules may corrode and short-circuit after being soaked, making repairs complicated; waterlogged interiors can develop mold and unpleasant odors, with high treatment costs. Typically, repair costs start at tens of thousands, and it's often not worth it for older cars. It's advisable to seek professional assessment, but in most cases, scrapping the car is more practical. After flooding, promptly tow the vehicle to avoid further damage, and conduct regular maintenance to prevent issues.

As a flood-damaged car survivor, my vehicle was completely submerged and took months to repair, costing a fortune without a full recovery. After the engine was overhauled due to water ingress, it always makes strange noises. Electrical system short circuits have left the AC dysfunctional, and the moldy interior stinks. Safe driving has become a concern. The repairs were time-consuming and labor-intensive—worse than scrapping it initially. Flood-damaged cars harbor many hidden dangers, like unreliable brakes posing significant risks. My personal lesson: avoid them if possible. Investing in a new car is more reliable and economical.

From a cost-saving perspective, most flood-damaged cars are not worth repairing. Cleaning the engine, replacing electronic components, and dealing with mold and rust can easily cost over ten thousand. If the car is of low value or old, the repair costs may exceed its worth. Insurance claims can provide some help, but depreciation is significant. Prompt action after flooding can minimize losses, but the decision should be based on a thorough assessment of the car's condition. High costs and risks make it generally difficult to recoup the investment.

How to Turn On the Rearview Mirror Heating Function?

Here is an introduction on how to activate the rearview mirror heating function: 1. Before using the rearview mirror heating, ensure that the vehicle is in the started state or turn the key to the ON position to power on the vehicle. The rearview mirror heating function can only be used when the power is connected. Avoid using this function when the vehicle battery is low or malfunctioning. 2. When turning on the rearview mirror heating switch, be careful not to confuse it with the front windshield defogging/defrosting button. The switch in the green circle is for the front windshield defogging/defrosting function, while the switch in the red circle is for the rearview mirror heating. 3. During rainy or snowy weather, after pressing the rearview mirror heating switch, the indicator light on the button will illuminate. The heating element will quickly warm up to a set temperature (typically between 35-60°C) within minutes. Both left and right rearview mirrors will emit warm air, and the water droplets on the mirror surface will gradually evaporate and shrink due to the rising temperature. The fog will also slowly disappear, achieving the effect of heating the mirror, defogging, and defrosting. 4. Some vehicles are designed to activate the rearview mirror heating function only when the ambient temperature is below 15°C. Therefore, if the rearview mirror heating does not work at times, first check if the outdoor temperature is too high. If temperature is not the issue and the rearview mirror heating still does not function, it is advisable to seek timely inspection and repair.

What causes a lean mixture in cylinder bank 1 at idle?

Idle mixture being too lean is mostly caused by the following reasons: clogged fuel injectors; excessive intake air; exhaust pipe leaks; aging or cracked PCV valve diaphragm causing air leaks. Here is additional information: Meaning: When the system indicates "too lean in cylinder bank 1 at idle," it means the air-fuel mixture in one bank of the engine is too lean. Automotive fuel injectors: A fuel injector is essentially a simple solenoid valve. When the solenoid coil is energized, it creates magnetic force that lifts the needle valve, opening the injection port. Fuel is sprayed at high speed through the annular gap between the needle valve and injection port, atomizing into fine mist for optimal combustion.

What are the reasons for the engine's high-temperature fan not rotating?

Car water temperature does not meet the requirements, or the relay is faulty, or the temperature control switch has issues. Water temperature not up to standard: Most of today's car radiator fans operate electronically via temperature control. Therefore, the fan usually only starts rotating normally when the car's internal water temperature reaches the required level. If the temperature is too low, the radiator fan cannot rotate. Solution: If the car radiator fan fails to rotate, the first step is to check whether the water temperature has reached the required level. If the water temperature cannot rise, the car engine needs to be inspected. Relay failure: If the water temperature meets the requirements but the car radiator fan still does not work, the problem might lie with the fan's relay. If the relay is faulty, the car's radiator fan cannot operate. Solution: Replace the damaged relay. Temperature control switch issues: Some faults in the temperature control switch can also affect the operation of the car radiator fan, so it is important to check this as well. Solution: Replace the damaged temperature control switch.

What are the reasons for the frequent stalling of the Buick Excelle GT automatic transmission?

Here are the reasons for the frequent stalling of the Buick Excelle GT automatic transmission: Stalling caused by carbon deposits: Carbon deposits usually accumulate in the throttle, spark plugs, cylinders, fuel lines, intake ducts, etc. They are a kind of coking substance produced by fuel under high temperature. General physical methods are difficult to remove, and special chemical cleaners are required for cleaning. Fuel quality and injector clogging: This situation is also relatively common. Using low-quality fuel not only produces more carbon deposits but may also clog the injectors, resulting in poor atomization. Additionally, low-quality fuel directly affects combustion efficiency, increasing fuel consumption. Unburned carbon monoxide entering the car and accumulating may even lead to poisoning and death. Ignition system issues: Common faults include spark plug carbon deposits and insufficient ignition voltage. The former can be addressed by using both physical and chemical methods to remove carbon deposits, while the latter can be resolved by replacing the spark plugs to address the insufficient voltage problem. Power supply issues: If the battery is severely depleted, it will make the engine difficult or even impossible to start. Generally, its service life is about 4 years. A nearly exhausted battery can be replaced, but repair is generally not recommended because the repaired battery has a short lifespan and is less reliable.

Is Compact Car Bigger Than Subcompact Car?

Compact cars are larger than subcompact cars. The classification of subcompact or compact cars is based on vehicle length and wheelbase. Generally, vehicles with a body length less than 4200mm and a wheelbase less than 2620mm are classified as subcompact cars. Compact cars typically have a body length between 4200mm-4600mm and a wheelbase between 2620mm-2700mm. Subcompact cars generally refer to A0-class vehicles within the A-segment. These vehicles usually have a wheelbase between 2.2 meters to 2.3 meters (some models may fall outside this range) and an engine displacement of 1.0 to 1.3 liters. Common examples of subcompact cars include: Xiali, Suzuki Swift, MG 3SW. Subcompact cars generally have low fuel consumption and compact dimensions, offering more comfortable and spacious interiors compared to microcars. Compact cars typically have larger exterior dimensions and interior space than subcompact cars, allowing them to accommodate more passengers. Compact cars, also known as A-segment cars, are the most common family vehicles, with wheelbases generally ranging from 2.5-2.7 meters and engine displacements around 1.6-2.0 liters. In China, the compact car segment includes domestic brands, joint-venture models, and imported vehicles. Common examples of compact cars include: Buick Excelle, Chevrolet Cruze, Hyundai Elantra, Nissan Sylphy, Mazda 3, Volkswagen Lavida, Bora, Ford Focus, etc.
