Do Cars Need Maintenance and Repair?

Why does the car blow hot air when the air conditioner is turned on?

There are several reasons why a car might blow hot air when the air conditioner is turned on: 1. Check if the air conditioner is set to cooling mode: If the cooling mode is not activated, no cold air will come out. The cooling switch for a car air conditioner is labeled AC. 2. Check if the external circulation mode is on: Running the air conditioner while the external circulation is active draws hot air from outside into the car, naturally reducing the cooling effect. Therefore, in hot weather, it's advisable to switch back to internal circulation after ventilating with external circulation. 3. Check if the car's air conditioning system is low on refrigerant: If the car is two or three years old and the air conditioner is not cooling or not cooling enough, it's highly likely that the refrigerant level is low. Generally, refrigerant loss is due to leaks, which can be either faulty or normal. Under normal circumstances, there might be minor leaks in the air conditioning pipes or condenser, so refrigerant typically needs to be replenished every two or three years.

Where is the crankshaft position sensor located on the Wuling Zhiguang?

The crankshaft position sensor on the Wuling Zhiguang is located at the junction between the cylinder block and the transmission. The crankshaft position sensor can receive signals from the gear ring on the timing belt pulley at the front end of the engine, driven by the crankshaft. Taking the 2020 Wuling Zhiguang as an example, it belongs to the microvan category with body dimensions of 3797mm in length, 1510mm in width, and 1820mm in height, a wheelbase of 2500mm, a fuel tank capacity of 38 liters, and a curb weight of 997kg. The 2020 Wuling Zhiguang features a MacPherson strut front suspension and a longitudinal leaf spring rear suspension. It is equipped with a 1.2L naturally aspirated engine delivering a maximum horsepower of 76PS, a maximum power of 56kW, and a maximum torque of 108Nm, paired with a 5-speed manual transmission.

What are the effects of a water-damaged car?

Corrosion of the chassis; reduced body tightness; musty odors and mold growth; decreased stability of the engine and transmission; increased risk of electrical fires, etc. Below is a detailed introduction: Water-damaged car: A water-damaged car refers to a vehicle that has been submerged in water, typically meaning the engine and transmission have been soaked, with the water level exceeding the wheels and body seats, and the bottom parts of the vehicle being in prolonged contact with water. Such vehicles pose significant risks, as the electrical circuits are prone to short circuits, fires, etc. Hazards: The dangers of water-damaged cars are substantial. If a vehicle is submerged in water, it can easily lead to rusting of body components, shortening its lifespan and reducing safety performance. For example, water damage can cause corrosion and rusting of the vehicle's wiring, leading to sudden engine shutdowns or spontaneous combustion due to short circuits while driving, with potentially catastrophic consequences. Additionally, the repair costs for water-damaged vehicles are very high, often exceeding 50% of the vehicle's value for severely water-damaged cars, and insurance claims can be very difficult to process.

What is the composition of the crankshaft flywheel assembly?

The crankshaft flywheel assembly consists of the crankshaft, crankshaft pulley, crankshaft torsional vibration damper, crankshaft main bearings, flywheel, starter ring gear, and other components. Below are the related introductions: 1. Function of the crankshaft: It converts the force transmitted from the connecting rod into rotational torque, which is then transmitted to the clutch via the flywheel, while simultaneously driving components such as the water pump, generator, and camshaft. The crankshaft is composed of main journals, connecting rod journals, crankshaft arms, counterweights, the crankshaft front end, and the crankshaft rear end. 2. Function of the flywheel: It stores the energy from the power stroke to provide power during non-power strokes and ensures smooth rotation of the crankshaft to reduce vibration. The flywheel also facilitates engine starting via the starter motor through its ring gear. Additionally, it serves as the driving disc of the clutch, transmitting the engine's power to the transmission system. The flywheel features top dead center (TDC) and ignition timing marks. 3. Engine firing order: In a four-stroke multi-cylinder engine, the crankshaft completes two full rotations for each cylinder to perform one power stroke.

Can Flood-Damaged Cars Be Used?

Flood-damaged cars can be used if the engine has not been flooded. Additional information: Flood-damaged cars: Flood-damaged cars refer to vehicles that have been submerged in water, typically meaning 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 and fires. Classification: Commonly referred to as flood-damaged cars or water-immersed cars, these are vehicles where the water level has reached about one-third of the wheel height. If the bottom of the vehicle body is submerged in water for an extended period, the extent of water immersion can vary greatly. Flood-damaged cars can be categorized into three levels: if the water level exceeds the vehicle's chassis, it is called a water-immersed car; if the water level exceeds the oil dipstick, it can be referred to as a semi-flooded car; and if the water level has surpassed the engine hood or the instrument panel, it is called a fully flooded car.

Can Flood-Damaged Vehicles Be Detected?

Flood-damaged vehicles can be detected. Both third-party inspection agencies and 4S shops can perform inspections for flood-damaged vehicles. Below is additional information: Flood-Damaged Vehicles: As the name suggests, flood-damaged vehicles refer to cars that have been submerged in water. Vehicles typically have markings indicating their wading depth in centimeters. When a vehicle exceeds this wading height, it can be classified as flood-damaged. Based on the extent of water damage, these vehicles can be divided into two types: one where the water level exceeds the wheels and enters the interior, referred to as partially flood-damaged vehicles, and another where the entire vehicle is submerged, known as severely flood-damaged vehicles. Hazards: The dangers of flood-damaged vehicles are significant. If a car is submerged, it can easily lead to rusting of body components, shortening its lifespan and reducing safety performance. Flood-damaged vehicles can cause corrosion and rusting of electrical wires, leading to sudden engine shutdowns or spontaneous combustion due to short circuits while driving, engine stalls at high speeds, airbags failing to deploy in critical moments or deploying unexpectedly, among other unimaginable consequences.
