Is Rust Under the Car Seat a Sign of a Flood-Damaged Vehicle?

Rust under the seat is just one reference point. It is recommended to check the gaps in the fuse box and the bottom of the seat belts. If there are water stains, it indicates water damage; if not, it only means there was water in the cabin. Below is additional information: 1. Precautions for major repairs of flood-damaged vehicles: If the powertrain is water-damaged, it can only be repaired by disassembly. To determine if the engine has been disassembled for major repairs, check the engine mount screws and other screws on the engine for signs of disassembly. For example, the engine mount screws are marked with torque lines during production, and after disassembly, the old marks will no longer align. You can also check the firewall behind the engine and the radiator grille at the front for signs of water. These areas are usually difficult to clean, and if the vehicle was indeed flood-damaged, there will be a noticeable waterline. 2. Main causes of rust under the seat: First, poor ventilation, and second, dampness. The seat contains metal components, and rust occurs due to moisture inside the vehicle or previous water ingress. Due to poor ventilation, over time, the floorboard corrodes, leading to rust.

What is a Flood-Damaged Car?

Flood-damaged car refers to a vehicle that has been submerged in water, typically meaning that the engine and transmission have been soaked, with the water level exceeding the wheels and vehicle seats, and the bottom components of the vehicle being in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits, fires, and other hazards. Below are the identification principles for flood-damaged cars: 1. Waterlogged car: The water level exceeds the vehicle's chassis, and such a car is called a waterlogged car. 2. Semi-flooded car: The water level exceeds the oil dipstick, and it is referred to as a semi-flooded car. 3. Fully flooded car: The water level exceeds the engine hood or the dashboard panel, and it is called a fully flooded car.

What are the precautions for changing Fit tires from 185 to 195?

Precautions for changing Fit tires from 185 to 195: 1. Note that the diameter of the tire will increase after replacement, so the ground clearance of the car will also increase, leading to higher fuel consumption and slower acceleration, but the car can run faster. 2. For small-displacement engines, it may also reduce the vehicle's acceleration capability. 3. 195 tires are more expensive than 185 tires, increasing the cost of tire replacement. 4. Changing the tire size may cause the vehicle to fail the annual inspection. Precautions for tire use: 1. Pay attention to tire pressure, as it is crucial for tire longevity—both too high and too low pressure will shorten the tire's lifespan. 2. If the pressure is too low, the tire body deformation increases, cracks may appear on the tire side, and flexing motion occurs, leading to excessive heat generation, which accelerates rubber aging, fatigue of the cord layer, and breakage of the cords.

What is the displacement of a car labeled 240?

240t refers to a 1.5T displacement, where 1.5t indicates the engine's displacement. A 1.5t engine is essentially a 1.5L naturally aspirated engine equipped with a turbocharger to enhance the engine's output power and torque. Below is relevant information: 1. Displacement calculation: There is currently no precise calculation standard for converting turbocharged displacement, as many vehicle-specific factors influence displacement, such as model differences and manufacturer-set values. Generally, a turbocharged engine's power output is comparable to that of a naturally aspirated engine with 1.3 to 1.5 times its displacement, so a 1.5t engine is roughly equivalent to a 2.0L displacement. 2. Working principle: Turbocharging utilizes exhaust gases produced during internal combustion engine operation to drive an air compressor, increasing air intake. Compared to naturally aspirated engines, turbocharged engines have better 'lung capacity.' Greater 'lung capacity' translates to more power and stronger burst performance. Under the same displacement conditions, turbocharged engines outperform naturally aspirated ones and may even exhibit performance beyond their class.

What Causes Reduced Airflow When Car AC Runs for a Long Time?

Reasons for reduced car AC airflow: Blocked dashboard vents; Air leakage in dashboard vent ducts; Abnormal air direction control mechanism; Faulty air direction control motor; Low blower fan speed; Malfunctioning blower speed control module; Frozen AC pipelines; Clogged cabin air filter. Causes of unpleasant odors in car AC systems are as follows: 1. Accumulated dust in interior filters and copper coils: After prolonged use, dust accumulates in the interior filters and copper coils, reaching a certain level that generates odors. When the AC is turned on, these odors disperse into the air. 2. Moisture inside the interior unit: Following cooling/heating operations, moisture often remains inside the interior unit. If the AC lacks a dry anti-mold function and shuts down immediately, this persistent moisture leads to mold growth over time, naturally producing musty odors.

What is the fuel tank capacity of the Great Wall Fengjun 7?

Fengjun 7-2022 2.0T gasoline two-wheel drive super value model GW4C20B has a fuel tank capacity of 70L. The engine is a 2.0L turbocharged engine, and the transmission is a 6-speed manual transmission (MT). The drive mode is front-engine rear-wheel drive. The front suspension type is double-wishbone torsion bar spring independent suspension, and the rear suspension type is leaf spring non-independent suspension. In the same class, the Rich 6-2021 2.4L manual two-wheel drive gasoline standard model 2TZD has a fuel tank capacity of 73L. During the actual refueling process, the amount of fuel may exceed the calibrated capacity. This is because the fuel tank capacity marked by the automobile manufacturer is the volume from the bottom of the fuel tank to the safety boundary. There is still a certain space from the safety boundary to the fuel tank opening. This space is to ensure that the fuel in the tank expands when the temperature rises without overflowing the safety space of the fuel tank. If the fuel is filled to the fuel tank opening during the refueling process, the actual refueling amount will be larger than the calibrated fuel tank capacity. If the owner wants to know the remaining fuel in the tank, they can observe the fuel gauge on the right side of the dashboard, which is marked with E and F. When the pointer is close to E, it means that the fuel is almost empty, and when it is close to F, it means that the fuel is sufficient.
