Car air conditioning solenoid valve failure manifests as the air conditioning system being unable to function properly, significantly reducing driving comfort. Location: The car air conditioning compressor solenoid valve is located at the front end of the clutch, controlling the opening and closing of the air conditioning system through power on and off. Function: The air conditioning solenoid valve regulates temperature by cutting off power to the solenoid coil when the set temperature is reached, causing the electromagnetic force to disappear and stopping the refrigerant circulation. Composition: The solenoid valve in the air conditioning system generally consists of an electromagnetic coil and a magnetic core, including one or more holes on the valve body. When the coil is energized or de-energized, the iron core action controls the connection and disconnection of the valve body. The electromagnetic coil is directly installed on the valve body, and the magnetic core is enclosed in a sealed tube.

Can I go to any 4S store for the first maintenance?

The first maintenance can be done at any 4S store of the same brand. You need to bring the first maintenance voucher and the vehicle's maintenance manual. The first maintenance is free and relatively simple, mainly involving an oil change and replacing the oil filter. When a car is newly purchased, it is in the break-in period, and the first maintenance should be done after this period. Once the vehicle enters the maintenance workshop, the owner should personally follow along to observe the entire maintenance process, especially to supervise the materials used by the maintenance workers and their work attitude. Following the process also allows the owner to learn some simple repair techniques and understand the basic structure of the car, which is very practical for dealing with sudden emergencies on the road in the future.

Why Can't the Handbrake Be Pulled?

The reasons why the handbrake cannot be pulled are as follows: 1. The pull wire has been used for a long time: Rust inside the pull wire causes it to be unable to be pulled, and the pull wire needs to be replaced. 2. The gap is too small: This causes the handbrake to be unable to be pulled, and a mechanic can adjust it. The handbrake does not need to be pulled too tight; generally, 4 to 6 ratchet teeth are sufficient. 3. Handbrake: The parking brake, commonly known as the handbrake, functions to provide resistance to the car when parked, preventing the car from rolling. The parking brake, also known as the handbrake or the parking gear in automatic transmissions, locks the drive shaft or rear wheels. There are different types of parking brakes, operated either by hand or foot through mechanical mechanisms. High-end cars are gradually adopting electronically controlled parking systems, commonly known as electronic handbrakes.

Is the first maintenance at 5,000 kilometers or 3,000 kilometers?

The first maintenance can be done at 3,000 kilometers, but it must be done by 5,000 kilometers. Given the road conditions in China, changing the engine oil more frequently is better for the car, especially in urban areas with frequent traffic congestion and stop-and-go conditions. During the break-in period, new cars often operate at low speeds with low RPMs, leading to more sludge deposits in the engine due to break-in impurities. Therefore, performing the first maintenance at 3,000 kilometers is normal. Once the vehicle enters the maintenance workshop, the owner can follow along to observe the entire maintenance process, particularly to supervise the materials used and the diligence of the maintenance workers. Following the process also allows the owner to learn some simple repair techniques and understand the basic structure of the car, which can be very practical for handling unexpected emergencies on the road in the future.

What to Do If the First Maintenance Is Overdue?

If the first maintenance is overdue and has not been performed yet, it is recommended that the car owner immediately go to the 4S shop for the first maintenance. The mileage for the first maintenance is generally 5,000 kilometers, and the owner must go for the first maintenance on time. The first maintenance for a car is usually very simple, typically requiring only an oil change and an oil filter replacement. Engine oil is very important for the engine; it is often referred to as the 'blood' of the engine. Inside the engine, oil serves to lubricate, cool, clean, and seal. Engine oil, motor oil, or engine lubricant is a substance enhanced with additives in a base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade oil viscosity index improvers.
