What are the three filters in a car and how often should they be replaced?

Car three filters refer to the air filter, oil filter, and fuel filter. It is recommended to replace the three filters every 5,000 kilometers. Below are the specific details of routine car maintenance items: 1. Oil and oil filter replacement: Mainly for the maintenance of the lubrication system. The primary function of the lubrication system is to effectively lubricate various components of the car engine to prevent excessive wear. The oil filter's role is to remove various impurities from the oil to ensure the normal operation of the lubrication system. The oil filter should be replaced together with the oil during an oil change. Under normal circumstances, a car should be serviced every 5,000 KM. 2. Filter element replacement: The air filter's function is to filter the air before it enters the cylinder, removing impurities, dust, sand, and other foreign particles. The cleaning and maintenance of the air filter depend on the usage environment. The fuel filter is generally replaced after driving 20,000-25,000 KM. 3. Spark plug replacement: Spark plugs are consumable parts and should be replaced every 20,000 KM. In addition, components such as brake fluid, transmission oil, battery, throttle, fuel injector, and brake pads are all inspection items during routine maintenance, and they should be serviced and maintained based on usage conditions.

What is the capacity of car windshield washer fluid?

Car windshield washer fluid capacity is about 1.5 liters, and the car windshield washer tank capacity is generally about 5 liters. Car windshield washer fluid is divided into 0-degree fluid for summer use and -20-degree or -35-degree fluid for winter use. The functions of car windshield washer fluid: Using washer fluid while driving keeps the front windshield transparent, prolongs the life of the glass and wipers, prevents window icing in winter, and prevents static electricity on the windows. How to add car windshield washer fluid: Turn on the wiper switch, and the washer fluid will spray from below the front windshield until the spray nozzles stop spraying. Open the washer fluid filler cap, add washer fluid, then turn on the wiper switch again to clear out the remaining fluid. When no more fluid sprays from the nozzles, add more washer fluid. Finally, close the washer fluid cap. Precautions for adding car windshield washer fluid: Understand your car's characteristics: Each car has different requirements for washer fluid, such as concentration, molecular weight requirements, and pressure capacity. Only by understanding these factors can you use washer fluid effectively. These data requirements are usually specified in the car's user manual. Choose the right washer fluid: Different car models may come with specific washer fluids for sale, which can be added directly. If not available, you may need to purchase and mix washer fluid in a certain ratio. When filling, avoid overfilling—add more if needed. Try to use the same brand of washer fluid to prevent pipe clogging.

What is the difference between internal and external tire pressure monitoring?

The difference between internal and external tire pressure monitoring lies in the installation method: internal tire pressure monitoring involves installing the sensor inside the tire, while external tire pressure monitoring involves installing the sensor outside the tire. The installation of internal tire pressure monitoring is more complex, requiring the tire to be removed. It is recommended to have it installed by professional automotive repair personnel, and after installation, the dynamic balance needs to be readjusted. The automotive tire pressure monitoring system is a set of initialization systems specifically designed for vehicle manufacturers to detect tire pressure. It uses wireless radio frequency technology to quickly activate, identify, and locate various TPMS sensors, and writes relevant information into the vehicle's ECU electronic control unit through the OBDII interface to initialize the tire pressure detection system.

Is an Aftermarket Catalytic Converter Effective?

It is effective, but only if the aftermarket part is of reliable quality. Here are the relevant details: 1. Function of the catalytic converter: The primary role of the catalytic converter is to oxidize and reduce three harmful gases—CO, HC, and NOx—into non-toxic and harmless substances such as water (H₂O), carbon dioxide (CO2), nitrogen (N2), and oxygen (O2). 2. Working principle of the catalytic converter: When high-temperature exhaust gases pass through the catalytic converter, the purifying agents inside enhance the activity of CO, HC, and NOx, promoting oxidation-reduction reactions. Specifically, CO is oxidized into colorless, non-toxic CO2 at high temperatures; HC is oxidized into H₂O and CO2; and NOx is reduced into N2 and O2.

What are the precautions for replacing a car battery?

Precautions for replacing a car battery include: 1. Ensure to confirm the battery model to avoid mismatching with the original battery; 2. The engine must be turned off during battery replacement to prevent safety hazards. Car batteries include conventional batteries, dry-charged batteries, and maintenance-free batteries. Conventional batteries have plates made of lead and lead oxide and are the traditional, inexpensive batteries on the market. Dry-charged batteries have a strong storage capacity in the negative plate and are relatively easy to maintain. Maintenance-free batteries are currently available on the market with features such as low electrolyte consumption, high-temperature resistance, strong power storage, minimal self-discharge, compact size, and high vibration resistance, requiring no maintenance.

Where is the wear limit indicator located on the brake disc?

The three grooves on the surface of the brake disc serve as the wear limit indicators. When these three grooves are worn flat, it's time to replace the brake disc. Alternatively, you can use professional tools to measure the remaining thickness of the brake disc and compare it with the standard thickness. If the wear reaches 2mm, it indicates that the brake disc has reached its wear limit. Here is some relevant information about brake discs: 1. Replacement timing for brake discs: Generally, brake discs need to be replaced after a vehicle has traveled 60,000-80,000 kilometers. However, this is not absolute. The wear condition of brake discs is closely related to the road conditions and driving habits of the owner. If the owner frequently drives in mountainous areas or congested urban roads, where braking is required more often, the brake discs will wear faster, shortening the replacement cycle. In some cases, replacement may be needed even before reaching 60,000 kilometers. Conversely, if the owner mainly drives on highways where braking is less frequent, the brake discs will last longer. 2. Methods to determine replacement: If we don't have professional tools to measure the wear of the brake disc, we can also use our hands to feel the edge of the brake disc to judge the depth of the scratches. If the edge becomes sharp and there are obvious scratches on the surface, it indicates severe wear and the need for immediate replacement. Note: Do not touch the brake disc directly when the car is hot, as it can cause burns.
