What causes the engine indicator light on the dashboard to illuminate?

The engine indicator light on the dashboard may illuminate for the following main reasons: 1. The engine warning light turns on for a few seconds and then turns off after starting the vehicle. This is the car performing a self-check, which is a normal phenomenon. 2. Poor quality or substandard gasoline: Shortly after refueling, the engine warning light appears on the dashboard. This is usually caused by filling up with low-quality gasoline at non-standard gas stations, leading to incomplete combustion of the air-fuel mixture during engine operation and triggering the engine warning light. 3. Spark plug carbon buildup: Carbon deposits on spark plugs can cause poor engine performance, resulting in abnormal phenomena such as difficulty starting, unstable idling, poor acceleration, backfiring during sudden acceleration, excessive exhaust emissions, and increased fuel consumption.

Can You Wax After Crystal Coating?

You can wax your car after crystal coating. Here is some information about crystal coating: 1. Crystal coating itself does not have waterproofing functionality; it merely forms a relatively hard film on the surface of the car paint. Waxing, however, can provide a waterproof effect for the car paint. 2. It's important to note that crystal coating has hydrophobic properties, which are sufficient for handling general rainy conditions. Unless the weather is extremely harsh, there is no need to wax your car after crystal coating. 3. If the crystal coating loses its effectiveness, it's best to reapply the coating or wax the car. Methods to determine if the crystal coating has failed: 1. Hydrophobicity test. If the crystal coating is still effective, pouring water onto the car paint surface will result in water droplets forming a lotus leaf or dewdrop effect. If it has failed, the water will stick together in patches. 2. Paint gloss. Crystal coating enhances the gloss, making it more vibrant and bright, with an overall shine that surpasses that of a washed car. If you observe the opposite of these effects and the car surface becomes prone to dirt (easily collects dust), it is highly likely that the crystal coating has lost its effectiveness.

What is the purpose of front fog lights on a car?

Front fog lights on a car serve to make the vehicle visible to others in conditions of reduced visibility such as foggy or rainy weather. Here are some key points about front fog lights: 1. Front fog lights are installed at the front of the vehicle, slightly lower than the headlights, to illuminate the road during rain or fog. 2. They typically emit yellow light because yellow is the purest color and has the strongest penetrating power. The yellow fog lights can penetrate thick fog and project over long distances, improving visibility for the driver and other road users.

How Many Years Can Shock Absorbers Last?

Shock Absorber Lifespan: 1. There is no fixed service life. 2. As long as the shock absorber shows no signs of oil leakage, internal rubber aging, cracking, etc., it can continue to be used. 3. Of course, when a vehicle reaches a certain age, it is essential to regularly inspect the working condition of the shock absorbers (generally, when the vehicle's mileage reaches 100,000 kilometers, regular inspections should be conducted). Here is some related information about shock absorbers: 1. The car shock absorber (including the suspension spring), as the most important component in the vehicle's vibration filtration system, is responsible for absorbing the vibrations and impacts generated by uneven road surfaces during driving, thereby providing a comfortable ride for the vehicle's occupants. 2. Once the shock absorber is damaged, the vehicle may experience excessive bumpiness and instability while driving, which in severe cases could even significantly impact driving safety.

What are the items included in the second maintenance of a car?

Secondary maintenance mainly includes the following items: 1. Measure the cylinder pressure of the engine and adjust the valve clearance; clean various filters, oil pan, and the assembly of the oil collector. 2. Check and adjust the wear and clearance of connecting rod bearings; inspect and tighten the bolts of the front and rear engine brackets. 3. Check and adjust the brake, perform tire rotation; inspect the clutch and adjustments of other assemblies. 4. Extension: Secondary maintenance is generally performed when the car has traveled 6,000~8,000 km. The purpose of secondary maintenance is to ensure that the vehicle maintains good operating performance for a long period of time thereafter.

Apart from the items that need to be replaced, there are also items that need to be inspected. 3. Items to be inspected: tire side slip condition, braking effect and pedal clearance, handbrake function, clutch clearance and clutch oil level, steering wheel clearance, air conditioning system, instrument functions, seat belts and warning systems, speed and exhaust, power steering system, drive shaft dust covers, exhaust muffler, suspension fixing nuts (chassis inspection), tires and rims, wheel bearings, etc.
