Removing and installing the air conditioning filter: When unscrewing and prying open the clips, be careful to apply the right amount of force. When installing the new air filter, ensure the arrow on the filter faces upward for better dust filtration. Replace the air filter cover and secure the clip on the right side. The air filter acts as the engine's 'nose,' filtering dust and impurities from the air to provide clean air to the engine cylinders, reducing wear on components like pistons and cylinders, and ensuring the engine operates efficiently and normally.

What is the normal idle speed for a Sylphy?

The normal idle speed for a Sylphy is around 800 RPM. Prolonged idling can have the following 5 effects on the vehicle: 1. Prolonged idling causes low engine temperature: Due to extended idling, the engine temperature remains too low, leading to incomplete fuel combustion, increased carbon deposits, clogged fuel injectors, and severe carbon buildup. 2. Maintaining idle speed results in poor fuel atomization and deterioration of lubricating oil: Unburned and poorly atomized fuel can wash down the cylinder walls and mix with the lubricating oil, diluting and degrading it. This causes increased engine wear as moving parts are inadequately lubricated. 3. Poor combustion in the engine leads to worsened exhaust emissions and the release of toxic gases. 4. Low idle speed reduces oil pump speed: A low idle speed results in reduced oil pump speed, leading to low oil pressure and insufficient lubrication at various points. 5. Idling makes it difficult for high-temperature engine components to dissipate heat: This can even cause damage to the catalytic converter due to excessive heat.

How to Check if a New Car Has Been Repaired?

To check if a new car has been repaired, you can visit a 4S store. Below are specific methods to check if a new car has been repaired: 1. Check maintenance records: You can visit a 4S store to check the maintenance records, or use some third-party software to check the car's maintenance records. If it's a new car, there is no insurance purchased, so it's impossible to check the claim records. If there are no repair records at the 4S store, you can hire a used car appraiser to inspect the car. During the repair process, some traces will be left, which a professional used car appraiser can identify. 2. Carefully inspect the car's appearance and odometer reading. A new car won't have minor bumps or dents. Open the engine hood and wheel covers, and carefully check if any screw caps show signs of being tampered with. New cars are generally assembled electrically, without any manual tightening marks. Odometer mileage. New cars are usually transported by carrier, and short-distance driving may occur, generally not exceeding 500 kilometers. However, odometer tampering exists, so be cautious about whether the dashboard screws show signs of being tampered with.
