How often should the spark plugs of a BMW X4 be replaced?

The spark plugs of a BMW X4 should be replaced every 50,000 kilometers. At 50,000 kilometers, it's time for a major maintenance service. In addition to the regular replacement of engine oil and the three filters, the throttle, brake fluid, and coolant should also be cleaned. The spark plugs should be replaced again at 100,000 kilometers. The BMW X4 is a mid-size SUV introduced by BMW, featuring a unique xDrive all-wheel-drive system that enhances its performance in terms of power. The BMW X4 adopts a front-engine, four-wheel-drive layout with an on-demand all-wheel-drive system. The front suspension of this vehicle uses a double-joint spring strut front axle suspension, while the rear suspension employs a five-link rear suspension. The chassis has been specially tuned to reduce body roll during acceleration and cornering.

How to use the automatic headlights of Haval H6?

Haval H6 automatic headlights usage method: Simply turn the rotary switch to the AUTO position. When driving, if there is insufficient light or the external light becomes dim, the light sensor will activate the circuit, and the headlights will automatically turn on. It is recommended to set models with automatic headlight function to AUTO mode by default. This can prevent forgetting to turn on the lights in low-light conditions, which is beneficial for driving safety. The dimensions of the Haval H6 are 4649mm in length, 1852mm in width, and 1710mm in height, with a wheelbase of 2680mm.

How to Solve the Black and White Issue with the Reversing Camera?

Solutions for a black and white reversing camera: 1. The car battery is dead. The display screen of the reversing camera relies on the car battery for power. When the car battery is dead, the reversing camera will not display. In this case, the car battery needs to be charged immediately. 2. Poor connection of the wiring. If the connection between the camera and the car display screen is loose, it can also cause the reversing camera not to display. In this case, simply reinstall the connection wiring. 3. Poor contact of the switch. In this case, the switch needs to be reinstalled. 4. Faulty reversing camera module. There are many reasons for a faulty reversing camera module, and it is necessary to visit a repair shop for professional inspection.

What Causes Coolant Leakage?

Coolant leakage causes: 1. Sealing issues in the cooling system, where the connection between the antifreeze tank and radiator is not tight, leading to coolant leakage; 2. Pipe problems, such as aging or cracking rubber hoses, causing coolant leakage; 3. Radiator issues, where corrosion leads to coolant leakage. Coolant leakage affects the vehicle's heat dissipation and can cause the cooling system to freeze and crack in winter, so it should be repaired promptly. Coolant, also known as antifreeze coolant, primarily functions to prevent freezing, cool, resist corrosion, and prevent scaling. Coolant is colored to distinguish it from other liquids, making leaks easier to detect.

What are the characteristics of a rotary engine?

Rotary engines are characterized by their compact size, relatively simple structure, excellent acceleration performance, and stable operation. Unlike conventional piston engines (excluding aircraft radial engines) that operate through reciprocating motion, rotary engines function via rotational movement, resulting in significantly less vibration and easier size control. Due to the low inertia of the rotor, rotary engines can quickly increase rotational speed, delivering superior acceleration performance. However, rotary engines have drawbacks such as high fuel consumption and heavy pollution. The absence of a high compression ratio like that in reciprocating engines leads to incomplete combustion. Although Mazda once introduced single and twin turbochargers to rotary engines, which increased horsepower output and moderately reduced exhaust emissions, they still lag far behind reciprocating engines in these aspects.

What Causes the Engine Yellow Light?

There are many reasons for the engine yellow light, such as poor gasoline quality, oxygen sensor failure, air flow sensor failure, spark plug carbon buildup, engine knocking, water temperature sensor damage, etc. When the engine yellow light comes on, it is necessary to use a computer to check the fault code, and then find and solve the related problems based on the meaning of the fault code. What to do when the engine yellow light comes on: 1. If the car cannot start, call for rescue or tow the car to a repair shop for inspection and repair; 2. If the car can drive normally and there are no other abnormalities, you can restart the car. Sometimes the engine yellow light is a misjudgment by the car system, and it can be eliminated by simply restarting; 3. If the car shows symptoms such as weak acceleration or abnormal engine noise after the yellow light comes on, it is not recommended to continue driving. Call a professional repairman to inspect and repair the car on the spot.
