What causes the intermittent cooling of the old Sagitar's air conditioning?

Here are the specific reasons why the old Sagitar's air conditioning sometimes cools and sometimes doesn't: 1. Dirty air filter: If maintenance hasn't been performed for a long time, the filter may be too dirty, affecting the cooling effect of the air conditioning. 2. Dirty condenser: A dirty condenser can also lead to poor cooling performance. The car's air conditioning condenser is located at the front of the vehicle and can be rinsed with a water hose. 3. Insufficient refrigerant: A lack of refrigerant in the air conditioning system's pipelines reduces pressure and results in poor cooling performance. Refill the refrigerant and check for any leaks in the air conditioning pipes.

What is the working principle of the clutch vacuum booster pump?

The working principle of the clutch vacuum booster pump is: The clutch vacuum booster pump utilizes the principle of air intake during engine operation to create a vacuum on one side of the booster. This generates a pressure difference compared to the normal air pressure on the other side, which is then used to enhance the braking thrust. During operation, the push rod return spring keeps the brake pedal in its initial position. At this time, the one-way valve at the connection point between the vacuum pipe and the vacuum booster is open. Inside the booster, a diaphragm divides it into a vacuum chamber and an application chamber. These two chambers can be interconnected, and for most of the time, they are isolated from the outside. The connection between the chambers and the atmosphere is achieved through a two-valve mechanism.

Why Do Aftermarket Headlights Turn Yellow?

If the headlights replaced are not from the 4S store but are aftermarket ones, the lamp covers are made of recycled plastic. Initially, they may look almost the same as the original ones, but the specific reasons for yellowing are as follows: 1. Time Factor: Over time, the plastic lamp covers will turn yellow. 2. 4S Store: Although the original headlights replaced at the 4S store are more expensive, they use the exact same parts as those installed at the factory, ensuring quality and preventing yellowing. Additional Information: Not all replaced headlights will turn yellow, but those that do are definitely not original and are of inferior quality. Using a lower-wattage bulb can slow down the yellowing process, but plastic headlights on domestic cars will eventually turn yellow.

How to Use the Keyless Entry System?

The method of using the keyless entry system is: the car owner carries the car key with them, and when opening the door, there is no need to take out the key. The car key automatically matches with the car's decoder when it is near the car. Simply press the unlock button on the car door handle to unlock. The car keyless entry system, abbreviated as PKE, adopts the world's advanced RFID radio frequency technology and an advanced vehicle identity coding recognition system. It pioneers the development of a miniaturized, low-power RF antenna solution, integrating both the remote control system and the keyless system, while maintaining the traditional vehicle circuit protection. This achieves a dual RF system and dual anti-theft protection, providing convenience and security for car owners.
