How Many Kilometers Should a Car Drive Before a Major Maintenance?

Generally, a vehicle requires a major maintenance after driving 30,000 kilometers. Here is the relevant information: 1. Major maintenance is based on minor maintenance, and in addition to replacing the engine oil and oil filter, it also includes replacing the air filter and fuel filter. These two filters serve to filter dust from the air and impurities from the fuel. The normal operation of the engine relies on the proper use of various maintenance products. If the oil and three filters are not replaced in time after reaching their service limits, it will adversely affect the engine's performance. 2. Currently, most car engines use a dry-type air filter with a paper filter element, which is lightweight, low-cost, easy to replace, and highly efficient. It is generally recommended to clean it every 5,000 kilometers. When cleaning, the filter element should be taken out and gently tapped on the end face, then blown with compressed air from the inside out to remove dust. Do not wash it with gasoline or water.

What is Car Boiling Over?

Car boiling over refers to the situation where the engine (also known as the motor or internal combustion engine, which can be divided into diesel engines and gasoline engines based on the type of fuel burned and ignition method) reaches a temperature that is excessively high for its normal operating range, thereby affecting the machine's performance and potentially causing damage. Extension: Conducting a comprehensive inspection of the car's cooling system is the primary method to prevent boiling over. Check whether the cooling fan is functioning properly, whether there are leaks in the radiator, and whether there is a lack of coolant. If the radiator is leaking, it needs to be repaired or replaced promptly. If the coolant level is low, it should be replenished in time. If the coolant appears cloudy or deteriorated, it should be replaced. Additionally, the water content in ordinary coolant can form a vapor barrier layer on the cylinder walls of the engine, hindering heat dissipation, leading to engine failure and shortening the engine's lifespan.

How to Deal with Fog on the Outside of the Car Windshield?

When there is fog on the outside of the car windshield, you should slightly increase the air conditioning temperature and adjust the vents to avoid blowing directly on the glass. Below are specific solutions for dealing with fog on the outside of the car windshield: 1. Use specialized defogging products: such as defogging sprays or anti-fog cloths. Spray these defogging products onto the inner surface of the car glass and wipe them clean. In addition to removing dirt from the glass, they also form a thin transparent protective film that prevents water vapor from condensing on the glass and forming fog. 2. Open windows for air circulation: Open the side windows slightly to create a gap. This allows air inside the car to circulate, gradually bringing the interior temperature closer to the outside temperature, which will help dissipate the fog. 3. Use the air conditioning system: Slightly increase the air conditioning temperature and adjust the vents to avoid blowing directly on the glass.
