What Maintenance Does a 4-Year-Old Car Need?

A car that has been in use for 4 years requires a major maintenance service, involving the replacement of several components such as engine oil, the three filters (air filter, oil filter, and fuel filter), cabin air filter, brake fluid, coolant, transmission fluid, and spark plugs. Among these, brake fluid and transmission fluid are particularly crucial. Below is a detailed introduction to car maintenance items: 1. Engine Oil and Oil Filter Replacement: This primarily pertains to the lubrication system's maintenance. The main function of the lubrication system is to effectively lubricate various components of the car's engine to prevent excessive wear. The oil filter's role is to remove various impurities from the engine oil, ensuring the proper functioning of the lubrication system. The oil filter should be replaced along with the engine oil during an oil change. Under normal circumstances, a car should undergo maintenance every 5,000 kilometers. 2. Filter Replacement: The air filter's function is to filter the air before it enters the cylinders, removing impurities such as dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is typically replaced after driving 20,000 to 25,000 kilometers. 3. Spark Plug Replacement: Spark plugs are consumable parts and should be replaced every 20,000 kilometers. Additionally, components such as brake fluid, transmission fluid, the battery, throttle body, fuel injectors, and brake pads are part of the routine inspection items during regular maintenance, and their servicing depends on usage conditions.

Why can't I see clearly when the sun shines on the windshield?

The sun cannot affect the transparency of the glass. The unclear vision is caused by water vapor inside the car. At this time, turning on the fan or air conditioner can solve the problem. Opening the car window is also a method. Here are some related tips for windshield maintenance: 1. Use suitable wiper blades: Use dedicated or appropriate wiper blades and replace them in time (usually once a year) to prevent scratching the windshield. 2. Clean frequently: Keep the windshield clean regularly. If there are debris, try not to use the wiper to remove them. Instead, use a towel or other tools to carefully remove them. 3. Use dedicated glass cleaner: Use car-specific glass cleaner. This can maintain a clear view while increasing lubrication and reducing wear on the windshield.

What does the term 'bar' mean in car tire pressure?

"bar" refers to the unit of pressure measurement, specifically megapascals, which is atmospheric pressure, commonly referred to as air pressure. Factors to consider for appropriate car tire pressure include: 1. Seasonal factors: Winter: Adjust slightly higher by about 0.2bar based on the standard tire pressure. Summer: Follow the lower limit of the standard tire pressure. For cars parked outdoors in summer, the pressure can be about 0.1bar lower than the standard. 2. Load conditions: Empty/half-load: Follow the lower limit of the standard tire pressure (the tire pressure indicated on the vehicle sticker can serve as the minimum reference). Full load: Follow the upper limit of the standard tire pressure (the maximum pressure indicated on the tire can serve as the theoretical maximum reference). 3. Tire pressure measurement environment: Hot tire: Note that hot and cold tires have different pressures, with a difference of about 0.3bar. Cold tire: Measure after the car has been parked for at least three hours or the tires have not been driven more than 2 kilometers. If measuring on a hot tire, subtract about 0.2bar from the measured value to get the cooled inflation pressure. 4. Road conditions: For rough roads, slightly decrease the pressure by 0.1-0.2bar from the standard. For smoother roads, adjustments can be negligible. For long-distance high-speed driving, ensure the pressure is not too low; slightly increase it by about 0.2bar from the standard lower limit. 5. Tire condition: New tires: Can be slightly higher by about 0.2bar than the standard. Old tires: Slightly lower than the standard, or follow the lower limit if severely worn. Soft tires (comfort treads): Slightly higher by about 0.2bar than the standard. Hard tires (performance treads): Follow the lower limit of the standard. 6. Spare tire pressure: Since spares are rarely used, keep the pressure higher to ensure it's effective in emergencies. Adjust to the appropriate pressure when in use, then reinflate to a higher pressure afterward.

What are the effects of a car without a catalytic converter?

In the absence of a catalytic converter, the chemical reactions between the three harmful gases in car exhaust occur at an extremely slow rate, and some reactions may not even take place. As a result, these harmful gases are almost entirely emitted into the atmosphere, significantly increasing air pollution. Below is a detailed introduction about it: 1. Introduction One: Generally, catalytic converters are made of ceramic materials, with internal catalysts primarily composed of three rare precious metals: platinum, rhodium, and palladium. These catalysts enable the harmful gases produced by engine combustion to undergo oxidation and reduction, ultimately transforming into harmless carbon dioxide, nitrogen, and water, thereby filtering the exhaust. 2. Introduction Two: Once the catalytic converter is damaged, the most noticeable symptom is a very pungent odor emitted from the rear of the car, as harmful substances like sulfur dioxide cannot be filtered. Most importantly, this causes irreversible pollution to the air.

What are the effects of a damaged car circuit board on the vehicle?

It can cause the car to fail to start. Basic knowledge of automotive circuits is as follows: 1. Power circuit: Composed of the battery, generator, voltage regulator, and operation display device, its main task is to supply power to all electrical equipment in the vehicle and maintain stable power supply voltage. 2. Starting circuit: Composed of the starter relay, starting switch, and starting protection device, its main task is to transition the engine from a stationary state to a self-operating state. 3. Ignition circuit: Composed of the distributor, electronic ignition controller, ignition coil, spark plugs, and ignition switch, its main task is to control and generate sufficient voltage to break down the spark plug electrode gap, while delivering high voltage to each cylinder's spark plug in the engine's working order. 4. Air conditioning control circuit: Composed of the air conditioning compressor electromagnetic clutch, air conditioning controller, control switch, and fan control circuit. 5. Instrument circuit: Composed of instruments, indicator gauges, sensors, various alarms, and controllers, its main task is to control the display of various instrument information parameters and alarms.
