"Flood-damaged cars" can be repaired to some extent, but even after repairs, there are serious hidden dangers. The longer the immersion time, the higher the probability of malfunctions. Related information: 1. Introduction: Flood-damaged cars can also be referred to as water-immersed cars, meaning the water level has reached about one-third of the wheel depth. If the bottom of the car body is soaked in water for a long time, the extent of water damage can vary significantly due to prolonged contact with water. 2. Expansion: Flood-damaged cars can be classified into three different levels for judgment. If the water level exceeds the car's chassis, it is considered a water-immersed car. If the water level exceeds the oil dipstick, it is called a semi-flooded car. If the water level has exceeded the engine hood or the dashboard, it is referred to as a fully flooded car.

As someone who almost bought a flood-damaged car before, I have to say the long-term effects of a semi-submerged vehicle after repairs are indeed significant. It might seem fine in the short term, but various issues can emerge over time. For instance, my friend’s car was half-submerged in water, and after repairs, it drove normally at first. However, a few months later, the electrical system started acting up—the AC worked intermittently, and warning lights would flicker on and off. Upon inspection, it turned out to be short-circuit risks caused by corroded wiring. In the long run, such cars are more prone to rust in metal components, with potential hidden risks in the chassis and engine, especially in areas with frequent rainy seasons where body corrosion accelerates, significantly increasing safety hazards. While repairs can restore basic functionality, the original electronic components and engine seals are hard to fully restore, compromising the car’s reliability. If you’ve bought such a vehicle, I’d strongly recommend regular thorough inspections, especially of the computer system and braking components—don’t wait until an accident happens to regret it. Safety should always come first. Repair costs might seem justified, but if you’re constantly fixing issues, it may be wiser to consider switching to a more reliable car, as the overall lifespan of a flood-damaged vehicle tends to shorten considerably.

From the perspective of someone who has repaired numerous flood-damaged vehicles, I've found that the long-term effects of partially submerged cars should not be underestimated. The key factors are the extent of water immersion and the quality of repair work. In most cases, vehicles can be restored to roadworthy condition with no immediate issues, but latent problems like electrical faults, sensor failures, or musty air conditioning odors often emerge within six months to a year. For instance, I recently worked on a car that had water up to wheel height - while it looked brand new after cosmetic repairs, moisture corrosion hidden in wiring connectors gradually caused control module failures. When vehicles are deeply submerged, fine sand or contaminants may enter the engine internals, accelerating wear over time. If repairs aren't thorough, corrosion can spread through the body frame, causing resale value to plummet as buyers can easily detect irregularities in vehicle history reports. My professional advice is to ensure replacement of all moisture-affected components during repairs - don't cut corners on small savings, but invest in comprehensive cleaning and rustproofing. Long-term data shows flood-damaged cars typically have 30% shorter lifespans, with cumulative repair costs potentially exceeding the vehicle's value. Therefore, when purchasing used cars, always meticulously check maintenance records and inspection reports - don't be tempted by seemingly good deals.

Where is the Wuling Journey's Cabin Air Filter Located?

The Wuling Journey's cabin air filter is located inside the glove compartment on the front passenger side. Below are details regarding the replacement cycle and precautions for the cabin air filter: Cabin Air Filter Replacement Cycle: First, the filter should be cleaned or replaced if necessary. The frequency of cleaning depends on road conditions (dusty roads, etc.). It is recommended to clean it earlier rather than later. The cabin air filter must be correctly installed in its designated position. Operating the air conditioning system without the filter in place may degrade its dustproof performance. It is advisable to replace the cabin air filter twice a year. Precautions for Replacing the Cabin Air Filter: The cabin air filter tends to accumulate a significant amount of dust. Use tools like a rubber air blower or high-pressure air gun to remove loose dust. Never wash it with water, as this can easily render it unusable. Over time, the activated carbon filtration function of the cabin air filter diminishes. Therefore, you can purchase a compatible replacement filter from the automotive parts market.

What does it mean when the PCS light is on in a car?

When the PCS light is on in the car, it indicates that the Pre-Collision Safety System has been turned off. Here is an introduction to the Pre-Collision Safety System: Principle of Pre-Collision: The Pre-Collision System (PCS) uses a millimeter-wave radar sensor installed at the front of the vehicle. This radar automatically detects obstacles ahead and calculates the likelihood of a collision. If the system determines that a collision is highly probable, it will sound an alarm to alert the driver to take evasive action. At this point, other active safety devices will also be integrated, with Brake Assist (BA) entering a preparatory state to assist the driver in applying the brakes. Function of the Pre-Collision Safety System: The Pre-Collision Safety System can also automatically adjust a series of safety systems, including the Pre-Collision Brake Assist System, Emergency Steering Assist System, and Vehicle Dynamics Integrated Management System, to avoid collisions as much as possible. If the system determines that a collision is unavoidable, it will pre-tighten the front seat belts and activate the brakes to minimize damage.

How to Choose Automotive Antifreeze?

Automotive antifreeze selection methods are: 1. Pay attention to the lower the freezing point the better. The basic indicators of antifreeze are freezing point and boiling point. Generally, the selected antifreeze's freezing point should be at least 10 degrees Celsius lower than the local minimum temperature to prepare for sudden weather changes; 2. Emphasize anti-corrosion function. The full name of antifreeze should be antifreeze coolant. Antifreeze prevents coolant from freezing and expanding to crack radiators or damage engine cylinders when parking in cold seasons. Antifreeze should be used year-round, not just in winter. In regular vehicle maintenance, engine antifreeze should be replaced every year, with higher replacement frequency for special vehicles.
