Why Does the Car Air Conditioner Make Noise?

What maintenance is generally done at 5,000 kilometers for a car?

Maintenance generally performed at 5,000 kilometers for a car includes: 1. Changing the engine oil and oil filter, and cleaning the air filter; 2. Checking the battery condition and the horn and lighting systems; 3. Checking the coolant level and freezing point, and cleaning the radiator; 4. Inspecting the braking system for leaks and ensuring the brake pads are within the specified thickness; 5. Examining the engine belt for wear and adjusting the belt tension; 6. Checking the transmission, drive shaft, and universal joint boots for leaks and damage. The benefits of maintenance include: 1. Ensuring the vehicle operates in optimal condition; 2. Improving vehicle efficiency and reducing wear on parts and tires; 3. Enhancing driving safety; 4. Preventing potential hazards caused by vehicle issues; 5. Reducing noise and environmental pollution; 6. Maintaining the vehicle's appearance and preventing damage.

What is the normal cylinder pressure for a car?

Car cylinder normal pressure values vary depending on different conditions: 1. For gasoline engines, the normal cylinder pressure ranges between 8 to 11 bar; 2. For diesel engines, the normal cylinder pressure ranges between 12 to 16 bar. The cylinder is composed of cylinder barrel, end cover, piston, piston rod, and sealing elements, and its function is to separate the turbine's flow path from the atmosphere, ensuring that steam completes the work process within the turbine. The method to check cylinder pressure is: 1. Install the cylinder pressure gauge on the engine; 2. Warm up the car, run the engine to normal operating temperature, maintaining coolant temperature around 90 degrees; 3. Remove all spark plugs or fuel injectors from the car; 4. Press the accelerator to fully open the throttle; 5. Screw the threaded connector into the spark plug hole; 6. Start the engine for two seconds, read the pressure value after the pointer stabilizes, press the one-way valve button to release pressure, allowing the pointer to reset.

What Causes Black or White Exhaust Pipes?

Black or white exhaust pipes are caused by carbon buildup: 1. Poor fuel quality or engine oil burning - vehicles that burn oil typically have very black exhaust pipes; 2. Auto start-stop systems - frequent starting and stopping prevents the engine from operating optimally, making it prone to turning black or white. Although black or white exhaust pipes don't necessarily indicate a malfunction, long-term carbon buildup can damage the engine, accelerate wear, naturally reduce power output, inevitably increase noise, and consequently raise fuel consumption. Therefore, regular maintenance of the fuel system and intake/exhaust systems is the best choice for reducing carbon deposits and lowering emissions.

What is the standard tire pressure for the Haval H6?

Haval H6 tire pressure standard seasonal factors: Winter: Based on the standard tire pressure of the car, it is appropriate to increase it by about 0.2 bar; Summer: Follow the lower limit of the standard tire pressure. If the car is parked outdoors in summer, the pressure can generally be about 0.1 bar lower than the standard to avoid tire blowouts due to high temperatures. The Haval H6 is a model under the Haval brand. The Haval H6 is equipped with the HiLife intelligent system in the Zhixuan version, which can start quickly and operate stably and reliably in both high-temperature and high-cold environments.
