Antifreeze can be stored unopened for 2-3 years. Antifreeze replacement cycle: Vehicle antifreeze generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference cycle. For commercial vehicles with longer mileage, the replacement cycle is shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition; if it is found to be insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the antifreeze, replace it immediately and clean the system. How to choose antifreeze: The basic indicators of antifreeze are its freezing point and boiling point. On the market, antifreeze is available in specifications with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region.

What are the common lubrication methods for engines?

There are three common lubrication methods for engines: pressure lubrication, splash lubrication, and gravity lubrication. Pressure lubrication: Uses an oil pump to deliver lubricating oil under pressure to the friction surfaces of components, forming an oil film of sufficient thickness to withstand mechanical loads, ensuring reliable lubrication. This method primarily serves components with high relative speeds and significant mechanical loads in the engine. Splash lubrication: Utilizes oil droplets splashed by rotating components such as the crankshaft and camshaft during engine operation or sprayed from oil holes in the connecting rod big end to lubricate friction surfaces. This method is used for components like cylinder walls, cams, and piston pins. Periodic lubrication: Involves the regular application of grease for lubrication, primarily targeting components such as the generator, starter motor, and water pump bearings.

What to Do When the Car Shakes During Cold Start but Runs Normally When Warm?

When experiencing shaking during cold start but normal operation when warm, it is advisable to promptly visit a professional repair shop or a 4S store for inspection. Below are detailed explanations: 1. Engine mechanical failure. For example, uneven cylinder pressure across cylinders. Solution: It is recommended that the owner visit a professional repair shop or a 4S store for inspection. 2. Intake system failure, such as intake pipe leakage. Excessive carbon buildup on intake valves and intake pipes, or excessive dirt on the throttle body and intake pipe walls. Solution: It is recommended that the owner visit a professional repair shop or a 4S store for inspection. 3. Engine management system failure. For example, incorrect coolant temperature or intake air temperature signals, or wiring faults. Solution: It is recommended that the owner visit a professional repair shop or a 4S store for inspection. 4. Ignition system failure. For example, excessive carbon buildup on spark plugs or incorrect gap, leakage in high-voltage wires or distributor cap, or damaged ignition coil. Solution: It is recommended that the owner visit a professional repair shop or a 4S store for inspection. 5. Fuel supply system failure. For example, injector nozzle closing improperly or being blocked due to excessive internal carbon buildup. Solution: It is recommended that the owner visit a professional repair shop or a 4S store for inspection. In addition to the faults mentioned above, other factors can also cause severe shaking during cold start. These faults cannot be resolved by the owner alone, so it is recommended that the owner visit a professional repair shop or a 4S store for inspection.

What to Do When Your Car Is Blocked and Can't Get Out?

Here are the solutions when your car is blocked and can't get out: 1. Check the insurance company of the blocking car: If your car is stuck due to another vehicle parked improperly, you can check the insurance company of that car. Usually, the insurance policy is pasted on the upper right corner of the front windshield. 2. If the other car is illegally parked on the roadside, call the police directly: Dial the traffic police number and report the location of the illegally parked car, which is obstructing normal traffic. After receiving the report, the traffic police will usually first identify the owner's information and contact them. If they can't be reached, a tow truck will be responsible for removing the vehicle. 3. Contact the parking lot administrator: If you are blocked in your residential community or a shopping mall parking lot, find a security guard or parking manager who can quickly contact the car owner.

What does in-person verification at the DMV mean?

In-person verification at the DMV refers to the process where the individual must be physically present at the main hall of the municipal DMV or any of its branch offices, carrying their second-generation ID card, to have their information recorded on-site. This replaces the previous paper-based review process, saving time and eliminating the need to submit the ID card. Scenarios requiring in-person verification: Generally, after a driving school student completes their medical examination, the school will register the student's information online, known as online verification. Only in cases where a student's identity or phone number information is abnormal is in-person verification required. Both online and in-person verification are processes for the Ministry of Public Security to confirm identity online. In-person verification process: After the medical examination, go to the location designated by the driving school to fill out the registration application form. Submit the ID card, residence permit, and application form to the staff for in-person verification (the individual must be present as a photo will be taken on-site). After verification, submit the medical examination form, registration form, and application form to the on-site staff (if the ID card is demagnetized or is a temporary ID, it must also be submitted along with the forms). Functions of in-person verification: After verification, you can apply for self-scheduling of initial driver's license tests, cross-regional testing systems, and driver's license renewal upon expiration. It also allows for replacement of vehicle registration certificates, changes to vehicle or driver contact information, traffic violation inquiries, pre-selection of vehicle license plate numbers, vehicle inspection appointments, and other driver and vehicle management services.

Can You Still Use a Car Cover in Rainy Weather?

You can use a car cover in rainy weather, but since the cover is not waterproof, it needs to be removed after the rain stops to allow the car to dry. The functions of a car cover: Primarily, a car cover is used to prevent rainwater from entering the vehicle, avoiding short circuits and damage to wiring or power sources; To protect the car paint from scratches, tree sap, insect residues, or acid rain damage during long-term parking; To shield the car from intense sunlight, which can harm the paint and rubber components; To prevent rainwater from corroding the metal parts inside the car during rainy days and to keep dust away during windy weather. When not to use a car cover: Do not cover if the car body has standing water: Over time, watermarks may form, which are difficult to remove. Typically, watermarks can only be addressed through car detailing, polishing, or grinding. Additionally, prolonged moisture on the paint can accelerate oxidation. If the car body has standing water and is covered, the trapped moisture will struggle to evaporate, leading to rusting of internal components over time. Do not cover if the car body is dirty: If the car is dirty, it must be washed before using a car cover to properly protect the paint; otherwise, the effort may backfire. Since the car cover is not a perfectly fitted protective film, it can shift relative to the car body, especially during strong winds. Covering a dirty car will cause dust and small stones on the surface to continuously rub against the paint, resulting in damage.
