What Causes the Engine Belt to Squeal When the AC is Turned On?

When the engine belt squeals upon turning on the AC, it is typically due to a loose or slipping compressor belt. Below are specific solutions: Solutions for AC belt noise: Turn on the AC and inspect whether the accessories driven by the belt have damaged bearings, are stuck, loose, or if the accessory power has increased. Consider replacing the belt or lightly sanding the contact surface between the pulley and belt with 100-grit sandpaper. Alternatively, you can apply 1-2 drops of engine oil to the contact surface between the belt and pulley to allow smoother operation. AC usage and maintenance: Select an appropriate AC temperature. In summer, many people prefer setting the temperature very low. However, excessively low temperatures can affect health, so it's important to adjust the temperature suitably. The most comfortable temperature range for humans is 20°C to 25°C. Above 28°C, people feel stuffy, while below 14°C, they feel cold. Therefore, the in-car temperature should be maintained between 18°C and 25°C. Excessively low temperatures can make people sick. In summer, avoid immediately switching to recirculation mode upon entering the car. Some drivers tend to turn on the AC and recirculation mode right after starting the car, thinking it cools the cabin faster. However, since the interior temperature is higher than outside, this approach is ineffective. Upon entering the car, first open the windows for ventilation and activate the external circulation to expel hot air. Once the cabin temperature drops, switch to recirculation mode.

What is the cleaning method for a car carburetor?

The cleaning method for a car carburetor is: remove the carburetor, first clean the exterior of the carburetor, then disassemble and separate its main components for cleaning. A specialized carburetor cleaner can be used for this purpose. The main parts of the carburetor that require cleaning are: the main fuel passage metering holes, the float chamber, and the float control needle valve. A carburetor is a mechanical device that mixes a certain proportion of gasoline with air under the vacuum created by the engine's operation. As a precise mechanical device, the carburetor utilizes the kinetic energy of the incoming air stream to atomize the gasoline. Its complete assembly should include a starting device, an idle device, a medium-load device, a full-load device, and an acceleration device.

Why does the compressor belt slip when the air conditioning is turned on?

When the air conditioning compressor belt slips upon turning on the air conditioning, it is due to the belt being too loose. Below is an introduction to the air conditioning belt: Introduction to the air conditioning belt: The multi-ribbed belt, also known as the air conditioning belt, functions to drive the generator, air conditioning compressor, and power steering pump. It is mounted on the crankshaft pulley and tensioned by the air conditioning belt tensioner. When this belt is damaged, you may experience heavy steering assistance or a complete loss of power steering. If the air conditioning is turned on, the air conditioning compressor will not start, resulting in no cooling. Impact of belt tension on the air conditioning system: The tension of the compressor drive belt directly affects the performance of the car's air conditioning system. If the compressor belt is too loose, it can lead to poor cooling performance. It is important to adjust the compressor belt promptly. If the belt slips severely when starting the air conditioning, a "squeaking" noise may occur, indicating that the belt and tensioner should be replaced. The tension of the compressor drive belt also significantly impacts the lifespan of the electromagnetic clutch. If the belt is too loose, the electromagnetic clutch is prone to slipping; if it is too tight, the load on the electromagnetic clutch increases. Improper belt tension can cause the compressor to malfunction or even lead to compressor damage. Additionally, if the compressor pulley and generator pulley are not aligned on the same plane during operation, it can reduce the lifespan of the drive belt or the compressor itself.
