The effects of not replacing spark plugs for a long time: 1. Insufficient vehicle power; 2. Difficulty in ignition; 3. The vehicle may suddenly stall; 4. Engine vibration; 5. Increased fuel consumption. The function of spark plugs is to ignite the engine by generating sparks between two electrodes. You can imagine the electrodes of a spark plug as the striking material on the side of a matchbox—over time, it wears out, making ignition much harder. Spark plugs have a limited lifespan, which varies depending on the material. Spark plugs are divided into ordinary copper-core (nickel alloy) spark plugs and precious metal spark plugs, with the main difference lying in the electrode part.

What Causes Abnormal Noise During Cold Engine Start?

Generally, it is caused by factors such as dirty engine oil, excessive viscosity, or piston knocking. It is recommended to visit a local 4S dealership for inspection and repair. Introduction to Car Engines: A car engine is the device that provides power to the vehicle, serving as the heart of the car. It determines the vehicle's power, fuel efficiency, stability, and environmental performance. Reasons for Warming Up the Engine: The main reason for warming up the engine is that after prolonged parking, the engine oil flows back into the oil pan at the bottom of the engine. Therefore, warming up is essential. The correct method for warming up is to drive off after 30 seconds to one minute of idling, but avoid high-speed driving during this time. Maintain low speeds and keep the engine RPM below 3000-3500, generally around 2000 RPM.

How to Remove the Steering Gear of the Cavalier?

The steps to remove the steering gear of the Cavalier are as follows: 1. First, remove the outer part of the steering wheel. If there are no screws at the back, gently apply force to detach the cover.

Take out the removal tool and remove the nut. Note that you should not immediately take out the steering wheel at this stage. Be sure to make alignment marks first to avoid misalignment during reinstallation, which could cause the steering wheel to be off-center. Reinstallation should follow the reverse order.

Why is the fuel gauge not displaying after replacing the instrument panel?

The reasons why the fuel gauge does not display after replacing the instrument panel: malfunction of the fuel float (fuel level sensor); short circuit in the fuel gauge wiring, etc. Malfunction of the fuel float (fuel level sensor): If it's an older car, it is very likely to be an issue with the fuel float, which is also known as the fuel level sensor by car owners. The car owner can check whether the fuel level sensor plug on the fuel tank is loose or oxidized and corroded; observe whether there is any sticking during the sliding process of the fuel level sensor. Short circuit in the fuel gauge wiring: If there is no problem with the fuel level sensor, then it is very likely that there is an issue with the fuel gauge wiring in the instrument panel. At this time, the instrument panel should be removed, and a multimeter and a large needle should be used to accurately locate and test the wiring corresponding to the fuel gauge on the instrument panel.
