What Causes a Car Air Conditioner That Won't Turn Off?

What needs to be replaced for a car's 20,000-kilometer maintenance?

For a car's 20,000-kilometer maintenance, you need to replace the oil filter, air filter, cabin air filter, and engine oil. Car maintenance is actually quite simple—it involves replacing some wear-and-tear parts and fluids. The fluids in a car include transmission fluid, power steering fluid, coolant, and brake fluid. The wear-and-tear parts include belts, wipers, spark plugs, tires, brake pads, brake rotors, and the battery. Car maintenance refers to the regular preventive work of inspecting, cleaning, replenishing, lubricating, adjusting, or replacing certain parts of the car. The purpose is to keep the car clean, maintain normal technical conditions, eliminate potential hazards, prevent failures, slow down the deterioration process, and extend the service life.

What Causes Brake Noise During Cold Start?

The reason for brake noise during cold start is: the sound produced by friction between the brake pads and brake discs, which is related to the material of the brake pads. If the hardness is too high or there are too many impurities, they can be removed and polished to ensure a flat contact surface, restoring normal operation and reducing wear on the brake discs. Timely maintenance and inspection ensure stable, comfortable, and safe driving. Braking tips: 1. When braking, release the brake before the vehicle comes to a complete stop. Continuously pressing the brake can cause a strong impact when the vehicle stops. Release the brake once before the vehicle stops completely, then gently press the brake until the vehicle stops. 2. When braking during a turn, pressing the brake while turning the steering wheel can cause the vehicle to lose balance. Before entering a turn, reduce the speed sufficiently by braking. Emergency braking on slippery curved roads can easily cause skidding. Reduce the transmission gear and use engine braking to slow down.

How often should the coolant be replaced in an Axela?

The recommended replacement interval for the Axela's coolant is approximately 60,000 kilometers. To prevent excessive foaming which reduces the heat exchange efficiency between the coolant and engine components, ensure the product is within its validity period when adding it. Long-life coolants can remain effective for up to three years. If suspended particles, sediment, discoloration, or deterioration are observed in the coolant, it should be replaced promptly, and the system should be cleaned. How to replace the coolant: Before performing a complete coolant replacement, conduct a thorough inspection to check for any leaks or cracks in the pipes, with particular attention to the five-way hose. The coolant is distributed to different parts of the vehicle through this hose to perform its function. If there are any signs of coolant leakage in this area, replace the hose or resecure the connection as necessary. Drain the old coolant and then flush the fluid channels with clean water. Add clean water to the coolant reservoir and continue filling until water flows continuously through the engine cooling system. Start the engine and let it idle for 3 to 5 minutes to circulate the water. Initially, the water draining from the reservoir may appear slightly pinkish. Continue adding clean water until the outflow is clear. Remember to remove the heater hose and drain all water from the heater core. After draining for about an hour, add the new coolant through the radiator hose. Then, pour another container of coolant into the reservoir until it is nearly full. Run the engine for about 10 minutes. As some air is expelled from the cooling system, the fluid level will drop. Top up the coolant to the "MAX" mark on the reservoir.

Should Front and Rear Brake Pads Be Replaced Together?

Front and rear brake pads are not replaced together, as they differ in replacement cycles. Under normal driving conditions, front brake pads typically need replacement every 30,000 to 50,000 kilometers, while rear brake pads can last approximately 60,000 to 100,000 kilometers before requiring replacement. There is no fixed timeframe for brake pad replacement, as the cycle depends not only on the service life of the brake pads but also on the vehicle's driving conditions and individual driving habits. New brake pads are about 15 millimeters thick and should be replaced promptly when worn down to one-third of their original thickness, or around 5 millimeters. When replacing brake pads, both pads on the same axle must be replaced simultaneously to ensure balanced braking performance on both sides.

What items are included in the driver's license physical examination?

Driver's license physical examination items include height, vision, color blindness test, hearing, trunk and neck movement dysfunction examination, upper limb and finger movement function examination, lower limb movement function examination, etc. For a C1 driver's license, the physical examination requires a height of at least 150cm, vision of at least 4.9 in both eyes, no red-green color blindness, the ability to distinguish the direction of sound sources with each ear at a distance of 50cm from a tuning fork, and three healthy fingers on each hand with normal movement function. The full name of a driver's license is a motor vehicle driver's license, also known as a driving license, which is a certificate required by law for motor vehicle drivers. Those lacking this skill may cause traffic accidents if they drive motor vehicles without authorization. Generally, individuals cannot drive on the road without a license.
