How Long Is the Shelf Life of Unopened Antifreeze?

Antifreeze has a shelf life of 2-3 years when unopened. 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 higher mileage, the replacement interval should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the antifreeze's condition—if it is insufficient, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed, replace the antifreeze immediately and flush the system. How to Choose Antifreeze: The key indicators for antifreeze are its freezing point and boiling point. Market-available antifreeze comes in specifications such as -15°C, -25°C, -30°C, and -40°C freezing points. Generally, choose an antifreeze with a freezing point at least 10°C lower than the lowest temperature in your region.

How to Determine if the Charcoal Canister is Damaged?

Methods to determine if the charcoal canister is damaged are as follows: 1. Remove the charcoal canister solenoid valve and blow air into the intake port with your mouth. If air does not pass through, the charcoal canister is not damaged. If air passes through, it indicates the charcoal canister is leaking and damaged. 2. While driving, there may be abnormal noises. If the engine speed is above 800 RPM and you hear a clicking sound, listen carefully to determine if the clicking is coming from the charcoal canister solenoid valve. If it is, there is no need to worry as it is a normal phenomenon. 3. If the car jerks when accelerating and the gasoline smell inside the car becomes stronger, check if the piping of the charcoal canister solenoid valve has cracked. 4. If the engine idle speed fluctuates regularly and the car struggles to accelerate, check if the air inlet and filter screen of the charcoal canister are clogged. 5. If the engine is difficult to start or suddenly stalls after being started with difficulty, it could also be due to a malfunction of the charcoal canister solenoid valve.

Does the vehicle going out of line in Subject 2 result in point deduction?

In the Subject 2 test, the vehicle going out of line results in a 100-point deduction. For reverse parking and parallel parking, if the vehicle body goes out of line, it directly results in a 100-point deduction. For right-angle turns and curve driving, if the wheels press against the road edge line, it also directly results in a 100-point deduction. In the Subject 2 steering judgment, there is no concept of 'brushing the line'; it only considers the vehicle body going out of line or the wheels pressing the line. Basically, 'brushing the line' can be understood as a situation where the vehicle body does not go out of line and the wheels do not press the line. Additional information: The Subject 2 test consists of five mandatory items: reverse parking, hill start, right-angle turns, parallel parking, and curve driving. For these five test items, failing any one of them means failing the entire Subject 2 test.

What happens if a car that requires 95 octane fuel is filled with 92 octane gasoline?

Occasionally using 92 octane gasoline in such a car won't cause significant issues, but prolonged use of 92 octane fuel may cause certain damage to the engine, and in severe cases, could lead to engine failure. The differences between 92 octane and 95 octane gasoline are as follows: 1. 92 octane gasoline refers to fuel with an octane rating of 92. 2. 95 octane gasoline refers to fuel with an octane rating of 95. 3. The chemical compositions used in both fuel types are quite similar, but 95 octane gasoline has higher fuel efficiency and provides more sufficient power for the vehicle. 4. Generally, naturally aspirated cars use 92 octane fuel, while turbocharged vehicles require 95 octane fuel.

What Causes Excessive Heat in a Motorcycle's Rear Wheel?

Here is an analysis of the reasons why a motorcycle's rear wheel may become excessively hot: 1. Prolonged Braking: Whether the rear wheel has a drum brake or disc brake, prolonged braking can cause the rear wheel to overheat. This is especially common with drum brakes due to their generally poorer heat dissipation. 2. Riding with the Brake On: Riding while keeping the brake engaged is equivalent to riding with the brake pedal pressed. This condition can easily cause the wheel to overheat, primarily due to brake system malfunctions or improper adjustment. 3. Bearing Damage: The rear wheel rotates smoothly mainly because of the bearings inside the hub. However, if these bearings lack lubrication, they may experience increased resistance or damage, causing the hub temperature to exceed the design standard. 4. Tire Overheating: If the tire pressure is insufficient, excessive deformation during operation can lead to overheating. This issue is related to the tire itself and has little to do with the wheel's mechanical structure.

What to Do When There's Water Vapor Inside the Car Taillight?

If it's just a small amount of condensation, turning on the lights for a while will help the vapor dissipate. However, if there are large water droplets, you'll need to remove the taillight and let it dry naturally or use a blow dryer. When washing your car, avoid using a high-pressure water gun to spray the taillights directly, as this can cause water to seep inside. Here are some key points for taillight maintenance: 1. Avoid Low-Quality Bulbs: The performance of bulbs is crucial as it affects nighttime visibility and driving safety. High-quality headlight bulbs are essential for safe driving. 2. Regular Maintenance: Just as your car needs routine checks for oil and filter changes, brake functionality, and other components, the headlight bulbs also require periodic inspection. Typically, after driving 50,000 kilometers or around 2 years, the brightness of headlight bulbs may diminish. It's advisable to visit a 4S shop for inspection. If the brightness is insufficient, replace the bulbs promptly, preferably both sides simultaneously to maintain uniform brightness.
