What Causes the Steering Wheel of Volvo S60 to Make Abnormal Noises When Turning?

Why does the car air conditioner make a hissing sound when the AC is turned on?

The reasons why the car air conditioner makes a hissing sound when the AC is turned on include: belt slippage, air conditioning compressor failure, or foreign objects in the air duct. More detailed information is as follows: 1. Belt slippage: The air conditioning compressor is driven by the engine crankshaft via a belt. If the belt becomes loose, aged, severely worn, or if the tensioner pulley lacks sufficient tension, it can cause the belt to slip, resulting in a hissing noise. Solution: If the belt slippage is caused by the belt itself, simply replace the belt. If the issue lies with the tensioner pulley, then the tensioner pulley needs to be replaced. 2. Air conditioning compressor failure: When the AC switch is turned on, the air conditioning compressor starts operating. If the compressor is damaged, it may produce a hissing noise. In this case, it is recommended to visit a 4S shop for direct replacement or repair. 3. Foreign objects in the air duct: If there are foreign objects in the air conditioning system's air duct, these objects may rotate repeatedly with the blower's airflow and collide with the air filter, causing a hissing sound. In this situation, you can remove the air filter and carefully inspect and clean any foreign objects in the air duct.

What happens if too much engine oil is added?

Here is the relevant introduction about excessive engine oil: 1. Oil burning fault: Excessive engine oil causes intense agitation of engine components during operation, which not only increases internal power loss but also leads to more oil splashing onto the cylinder walls, resulting in oil burning faults. 2. Power reduction: It creates significant resistance to the high-speed rotating crankshaft connecting rod mechanism, leading to decreased power output. 3. Catalytic converter poisoning: Increased oil entering the combustion chamber worsens exhaust emissions. In severe cases, it may cause catalytic converter poisoning and damage. 4. Increased fuel consumption: It raises vehicle driving fuel consumption and causes oil burning.

How long does it take to get a paint touch-up at a 4S shop?

Paint touch-ups at 4S shops usually require queuing, and even minor scratches may take 4-5 days. You can opt for repair shops, which are faster. For small-area touch-ups, you can typically drop off and pick up your car on the same day. Additional information: 1. Location choice: Whether you go to a 4S shop or a repair shop for painting, the final paint finish is generally similar. However, it's important to choose a professional repair shop that specializes in car maintenance and detailing. While 4S shops may have more advanced equipment, offering advantages in paint mixing and color matching, many repair shops nowadays are also well-equipped to enhance efficiency and competitiveness, often using similar equipment to 4S shops. 2. Touch-up time: Painting the front and rear bumpers is relatively straightforward. If there's a quick car detailing shop nearby, the repair, touch-up, and polishing can be completed in about 5 hours. For trunk touch-ups, if the damage is severe, panel beating takes about 6 hours, and applying putty and painting takes about 5 hours. For less severe damage, panel beating, putty application, and painting take around 7 hours.
