The process of cleaning the engine at a 4S shop is as follows: 1. Tools needed: cleaning agent, brush (or a discarded toothbrush), towel, and spray bottle. The biggest sources of pollution in the car engine compartment are dust and mud. If the owner wants to clean the engine compartment by themselves, they can prepare engine cleaning agent, a brush (or a discarded toothbrush), a towel, and a spray bottle. These tools are basically sufficient. 2. Use the cleaning agent for cleaning: Here, it is important to remind everyone not to spray water directly. It is best to use a cleaning agent because the purpose of using the cleaning agent is to remove oil stains in the engine compartment. Therefore, when using it, the owner should focus on spraying the cleaning agent on various parts and then carefully clean them with a small brush. The owner should note that after the operation, they still need to rinse with water bit by bit before air-drying to easily achieve the cleaning purpose. 3. Then use a wet towel: If the owner has plenty of time, they can choose to use a wet towel to clean the engine compartment. This method can also effectively avoid splashing water that may damage related circuits when pouring water. So, carefully cleaning with a wet towel bit by bit works really well. 4. Dry the moisture: If you want the moisture in the compartment to dry faster, you can start the engine after wiping off the moisture and use the heat generated by the engine to dry the moisture attached to the surface. Once the moisture is completely evaporated, the cleaning of the engine compartment is complete.

Getting your engine cleaned at a 4S shop is great—they usually follow a professional process. Before starting, the technician will inspect the engine bay for any oil stains or dirt buildup, then apply a specialized cleaner and let it soak for a while. Next, they’ll gently scrub using a steam cleaner or low-pressure water gun, being extra careful to avoid sensitive components like wiring and electronics to prevent short circuits or damage. After cleaning, they’ll blow-dry the area and inspect all wiring to ensure safety. The whole process takes about 30 minutes to an hour and typically costs a few hundred bucks—totally worth it. I think doing this regularly can prevent oil buildup from causing odors or affecting heat dissipation, and may even extend the engine’s lifespan. This service is often included in maintenance packages, and I’d recommend booking in advance to avoid waiting in line.

How to Start a Car Engine?

Steps to start a car engine: 1. Insert the key into the ignition switch and turn it to the second position; 2. Press the clutch, shift to neutral, slightly press the accelerator (fuel-injected engines do not require this), then turn the key to the fourth position to start the engine. After starting, listen for any abnormal sounds from the engine, check if any warning lights or indicators show abnormalities, and ensure all gauges are functioning normally. Key points to note when starting the engine with a key: 1. Do not turn the key back to the start position after the engine has started, and avoid using modified keys; 2. The ignition switch should not remain in the start position for more than five seconds. If the first attempt to start the engine fails, wait at least thirty seconds before trying again.

How to Clean Rust in a Car Radiator?

Methods for cleaning rust in a car radiator: 1. Manual cleaning, which requires removing the car radiator and using scraping or shoveling to remove the rust. Although this method can eliminate scale, it is inefficient, labor-intensive, difficult to clean thoroughly, and may cause secondary damage to the radiator. 2. Using a scale cleaner, which also requires dismantling the radiator and may lead to aging and a shortened lifespan. 3. Professional car radiator descaler cleaning, where a specialized scale cleaner is directly poured into the car's water circulation system. After letting it soak, idle, or drive for 20 to 30 minutes, the descaler is drained from the radiator and system, followed by repeated rinsing with water until clean.

What is the sequence of the Subject 2 driving test?

Different test centers may have varying routes and arrangements, so the order of test items can differ. However, the overall content of the test remains the same. The Subject 2 driving test includes five mandatory items: reversing into a parking space (garage), parallel parking, stopping and starting on a slope, turning at a right angle, and driving through curves (commonly known as S-turns). Reversing into a parking space (garage): During the test, the vehicle must not stop while moving forward or backward. Starting from one end of the road, the vehicle must reverse into the garage after crossing the control line (with the vehicle body over the line), then move forward to exit the garage and proceed to the other end before reversing into the garage again. Finally, the vehicle must move forward to exit the garage. Parallel parking: After stopping the vehicle on the right side in front of the parking space, the driver must reverse into the space in one attempt without stopping midway. The wheels must not cross or touch the lane boundary lines or the parking space lines. Driving through curves: The driver must enter the curve from one end and exit from the other. Steering and speed must be smooth and steady. The vehicle must not stop midway, and the wheels must not touch the lane boundary lines. Turning at a right angle: The driver must follow the designated route and make a single right-angle turn, either from left to right or right to left, without stopping midway. The wheels must not touch the lane boundary lines. Stopping and starting on a slope: The driver must accurately stop the vehicle and start smoothly without rolling backward. The starting time must not exceed 30 seconds. Subject 2 test rules: All five test items must be completed successfully in one attempt for the test to be passed. There are two test attempts in total, meaning a retest is allowed immediately if the first attempt fails. If the retest also fails, the candidate must wait 10 days before scheduling another test. After completing the test, candidates must leave the test area promptly and must not interfere with other test-takers.
