Should I Service My Car Before or After the Annual Inspection?

In general, it is recommended to service your car before the annual inspection. This is because if your car fails the inspection, you will not receive the inspection compliance sticker until the necessary repairs are completed and the car passes a re-inspection. Additionally, annual inspections require payment, and if certain items fail, you will need to pay again for re-inspection. Moreover, the lines for annual inspections are often long, sometimes requiring a full day of waiting. Below are some key points about car maintenance: 1. Exterior Inspection: Before driving, check the doors, hood, trunk, and glass condition. Inspect the body for damage, tilting, oil leaks, or coolant leaks. 2. Engine and Fluids: Check the tightness of engine components and inspect for oil or coolant leaks at joints. Adjust belt tension and inspect the fastening of hoses and wiring. Top up engine oil, coolant, and battery fluid as needed. 3. Tires: Check tire wear and clean the trunk. Replace tires when they approach the wear indicators. Look for bulges, abnormal wear, cracks, or other damage. 4. Cleaning and Lubrication: Clean grease from the hood, door, and trunk hinges, then lubricate them. Antifreeze typically lasts two years and should be replaced during maintenance, along with a thorough cooling system flush. Due to brake fluid's hygroscopic nature, replace it every two years.

What is the working principle of the Honda CM400 water pump?

The following is the relevant working principle of the Honda CM400 water pump: 1. Engine power: The engine drives the water pump bearing and impeller through the pulley. The coolant in the water pump is rotated by the impeller and, under centrifugal force, is thrown toward the edge of the water pump housing, generating a certain pressure before flowing out through the outlet or water pipe. 2. Impeller function: The pressure at the center of the impeller decreases as the coolant is thrown outward. The coolant in the radiator is drawn into the impeller through the water pipe due to the pressure difference between the water pump inlet and the impeller center, achieving reciprocating circulation of the coolant. The bearing supporting the water pump shaft is lubricated with grease, so it is necessary to prevent coolant leakage into the grease to avoid emulsification, as well as to prevent grease leakage. 3. Coolant sealing: The sealing measures to prevent leakage in the water pump include the water seal and gasket. The dynamic sealing ring of the water seal is installed between the impeller and the bearing through an interference fit, while the static sealing seat of the water seal is tightly pressed into the water pump housing to seal the coolant. The water pump housing is connected to the engine via a gasket and supports moving components such as the bearing. 4. Drain hole: There is also a drain hole on the water pump housing, located between the water seal and the bearing. If any coolant leaks past the water seal, it can drain out through the drain hole to prevent coolant from entering the bearing chamber, which could damage the bearing lubrication and cause component corrosion. If coolant continues to leak after the engine stops, it indicates that the water seal is damaged.

What is the process for the C2 automatic transmission Subject 2 driving test?

The C2 Subject 2 test items include: reverse parking, parallel parking, curve driving, and right-angle turns. Some regions may also include a highway toll card retrieval task. According to Article 25 of the "Regulations on the Application and Use of Motor Vehicle Driving Licenses" (Ministry of Public Security Order No. 123), starting from June 1, 2021, the C2 and C5 Subject 2 tests no longer assess hill start and stop. Compared to the C1 manual transmission test, the C2 test does not include the hill start item. Subject 2 test introduction and tips: Before starting the test, adjust your seat height and rearview mirrors to ensure a clear view, and fasten your seatbelt. During the test, do not stop unless the system indicates a failure. Parallel parking: Park the car in the designated space without crossing or touching the lines. Tips: Find the correct angle, turn the steering wheel quickly, react promptly, and coordinate with the car's speed. Right-angle turns: Prepare for a 90-degree turn while driving straight, ensuring not to cross or touch the lines. Tips: Identify the reference point before turning and coordinate with the car's speed. Curve driving (S-curve): Drive slowly through the S-curve without crossing or touching the lines. Tips: Control your speed, drive slowly, and time the turns correctly. Reverse parking: Reverse the car into the parking space without stalling or crossing/touching the lines. Tips: Control your speed, find the reference point, and make minor adjustments if the car deviates. Highway toll card retrieval tips: Slow down when approaching the toll station. There are two types of card retrieval: manual and self-service. For manual retrieval, align the car properly at the window. For self-service, move closer to the card machine. In both cases, shift to neutral and engage the handbrake. If you fail the Subject 2 test, you can retake it once. If you fail again, the test ends, and you must reschedule after 10 days. If you fail five consecutive times (including retakes, totaling 10 attempts), all previously passed subjects will be invalidated, and you must restart from Subject 1. Subject 2 penalty items: Reverse parking: Vehicle crossing the line (100 points, fail); failing to park properly (100 points, fail); stopping midway (5 points per instance); exceeding time limit (100 points, fail). Parallel parking: Vehicle crossing the line after stopping (100 points, fail); stopping midway (5 points per instance); tires or body touching the line (10 points); exceeding time limit (100 points, fail). Curve driving: Wheels crossing the edge line (fail); stopping midway (fail); not using second gear or higher (5 points). Right-angle turns: Wheels crossing the edge line (fail); stopping midway (5 points per instance). After stopping, if the vehicle is 30-50 cm from the edge line (10 points).

What to Do When the 'Service' Light Comes On in a Car?

Here are the solutions when the 'service' light appears in a car: 1. It is necessary to replace the engine oil and oil filter of the vehicle. 2. When the maintenance reminder of the vehicle lights up, it indicates that the vehicle has reached the required maintenance cycle. 3. You can drive the vehicle to an after-sales service center or a repair shop for maintenance. After maintenance, the service light will be reset. It will light up again when the next maintenance mileage is reached, reminding the driver to perform vehicle maintenance.

Do car radiators need frequent water refills?

If the radiator isn't leaking, you may not need to add water all year, but regular checks are necessary. Here are relevant details: 1. Antifreeze: What you add to a car radiator isn't tap water or purified water, but automotive antifreeze. In emergency situations when antifreeze isn't available, small amounts of purified water can be added temporarily - but only minimal quantities, otherwise serious consequences may occur. 2. No mixing: During winter, automotive antifreeze must be used, and it must be the same brand. Different antifreeze brands may contain different components, and mixing them could lead to other problems.
