Antifreeze should not be mixed. Different antifreeze products have varying production formulas, and mixing them may cause chemical reactions between additives, leading to additive failure. Types of Antifreeze: Antifreeze is generally categorized into three types: ethanol-water, glycerin-water, and ethylene glycol-water. How to Choose Antifreeze: The key indicators for antifreeze are freezing point and boiling point. Market-available antifreeze comes in specifications like -15°C, -25°C, -30°C, and -40°C freezing points. It is advisable to choose one that is at least 10°C lower than the lowest temperature in your region. How to Check for Low Antifreeze Levels: Observe the antifreeze warning light on the dashboard. If it lights up, it likely indicates low antifreeze levels, though it could also be due to excessively high engine temperature. Check the antifreeze reservoir. If the fluid level is below the minimum mark (MIN), do not continue driving and add antifreeze promptly. Inspect the water level markings on the antifreeze tank. Normal antifreeze levels should be between the maximum and minimum marks. If the level is below the minimum, it indicates a deficiency.

Is It Normal for the Electronic Parking Brake to Make Loud Noises When Engaging and Disengaging?

When the electronic parking brake is engaged or released, there will be a motor operating sound. This noise is produced by the motor controlling the rear wheel brake calipers or the tensioner, which is a normal occurrence and does not require excessive concern. However, if other abnormal noises occur, it is necessary to promptly send the car for inspection to ensure driving safety. The advantages of the electronic parking brake are as follows: 1. Simple operation: The biggest advantage of the electronic parking brake is its simplicity—just flick a switch to activate the parking brake function. Additionally, the settings of the electronic parking brake are more user-friendly, as it can be engaged under any circumstances. 2. High safety factor: If accidentally pressed while driving, the electronic parking brake will not activate as long as the throttle is still in the working position. If pressed during emergency braking, the electronic parking brake will not lock the wheels but will provide stronger braking force to assist in stopping.

How Many Times Can a Clutch Plate Burn Out?

Occasional burning of the clutch plate is not a major issue, especially if it happens briefly, as surface wear may not necessitate replacement. However, if the clutch is held in a semi-engaged state for prolonged periods at high engine speeds, the wear increases significantly. This leads to a strong burning smell due to rising temperatures, accompanied by symptoms like shaking, slipping, and unusual noises, indicating the need for replacement. Signs of a burnt-out clutch include: 1. Reduced Power: The engine's power output is transmitted to the transmission via the clutch. A burnt clutch causes the plate to slip, resulting in decreased power. 2. Metallic Grinding Noise: The friction surface of the clutch plate is secured with rivets. Burning the clutch wears down this surface, exposing the rivets to contact with the flywheel, creating a metallic grinding noise when engaging or disengaging the clutch. 3. Gear Shift Jerkiness: The clutch plate contacts the flywheel. When burnt, exposed rivets cause a strong jerking sensation during gear shifts.

What is a Flood-Damaged Vehicle?

Flood-damaged vehicles refer to water-soaked cars that are sold to second-hand car markets across China through certain channels. Below are the hidden dangers of flood-damaged vehicles: Damage to electronic control units: These units can become oxidized due to prolonged soaking, often requiring inspection and replacement; otherwise, they may fail to function properly. Since many electronic components cannot be opened for inspection at once, they may appear fine during repairs but could develop faults later during use. These issues mean that some flood-damaged vehicles may experience malfunctions even after being repaired. Engine damage: The water can harm the vehicle's internal electronic control systems. The engine is particularly vulnerable—never attempt to start or turn over a flooded engine, as this can cause severe deformation of the connecting rods. Additionally, prolonged soaking can damage interior components like carpets and seats, leading to material deformation, roughness, foul odors, and bacterial growth.

What Insurance Should Be Purchased for a New Car?

When buying a new car, it is recommended that owners purchase compulsory traffic insurance, vehicle damage insurance, and third-party liability insurance. Below are the introductions to the relevant insurances: Compulsory Traffic Insurance: Compulsory traffic insurance is a mandatory insurance required by the state. Without it, the car cannot be driven on the road, and the vehicle will also lose its eligibility for annual inspection. Vehicle Damage Insurance: Vehicle damage insurance is the most comprehensive necessary insurance with the widest coverage. This insurance is essential and truly practical, as purchasing it can reduce personal losses. Third-Party Liability Insurance: Third-party liability insurance is a 'supplementary insurance.' Since the compensation amount of compulsory traffic insurance is limited, third-party liability insurance can cover the portion that exceeds the compulsory insurance's limit. In the event of an accident, it allows for more reasonable compensation amounts and more comprehensive reimbursement.

What is the fuel consumption per 100 kilometers for the Crown?

The fuel consumption per 100 kilometers for the Crown is 9.81 liters. Below is an introduction on how to check fuel consumption and factors affecting it: Methods to check fuel consumption: The fuel gauge on the engine displays the fuel level, indicating and monitoring the fuel reserve and consumption in the tank. 'F' stands for full, and 'E' stands for empty. When the fuel warning light comes on, record the mileage, then refuel. When the fuel runs out next time, record the mileage again. Subtract the two mileage readings to get the actual distance traveled, then divide by the fuel consumed to calculate the fuel consumption. Factors affecting fuel consumption: Incorrect driving habits have the most significant impact on fuel consumption. During driving, especially in heavy traffic, at red lights, or when changing lanes, sudden acceleration and braking are common issues. Rough roads increase fuel consumption; driving on congested or uneven roads in low gear for extended periods will inevitably raise fuel usage. Neglecting maintenance also leads to higher fuel consumption. Scientific maintenance can help save fuel.

How Often Does a Car Need a Major Service?

Under normal circumstances, a car's major service should be performed every three years or 60,000 kilometers. Fluid Inspection: Necessary checks include the car's fluids, such as brake fluid, coolant, power steering fluid, transmission fluid, etc. Additionally, tasks like carbon deposit removal, battery replacement, spark plug replacement, and timing belt replacement will also be addressed. Carbon Deposit Removal: For turbocharged engine cars, the most crucial aspect is carbon deposit removal. In such cases, engine carbon buildup can become severe, and excessive deposits can lead to reduced power, difficulty in starting, increased fuel consumption, and even engine stalling, making the car unable to operate normally. Therefore, this should be given extra attention during a major service. Battery Maintenance: Regarding battery maintenance, modern cars are equipped with numerous electronic devices, resulting in significant battery consumption. For example, failing to turn off the air conditioning after shutting off the engine can lead to battery drain. Thus, the battery should also be regularly inspected and maintained.
