Can the inside of the hood be washed with water?

It is not advisable to wash the inside of a car hood with water. Here are the reasons why you should avoid washing the inside of the hood with water: 1. It can easily damage the alternator, which may lead to its failure. 2. If the engine is hot, the sudden cooling effect from water can cause significant damage due to thermal expansion and contraction. Since the engine block is made of metal, rapid cooling can lead to cracking. 3. The engine compartment contains numerous electrical wiring, which can malfunction or accelerate aging when exposed to water. If you still wish to clean with water, ensure proper waterproofing of critical components. It is recommended to use compressed air for cleaning instead. Precautions for water cleaning: 1. Cover the alternator, distributor, brake fluid reservoir, etc., with a cloth or seal them in plastic bags, especially the alternator and distributor. 2. Try to wash only after the engine has cooled down. Avoid using high-pressure water jets. 3. After washing, thoroughly dry the engine compartment with a clean cloth, especially the underside of the hood. 4. Do not aim the water jet directly at the air intake or wiring connectors.

What causes Jetta to shake at idle but not when accelerating?

Jetta shaking at idle but not when accelerating should be classified as unstable idle speed, usually caused by leaks in the intake pipe and various valves, excessive carbon buildup on valves and intake pipes, malfunctions in sensors and circuits controlling idle speed, or ignition system failures. Below are specific reasons: 1. Unstable idle speed: Unstable idle speed is one of the most common issues in the daily maintenance of electronically controlled engines. Common causes include cracked intake manifolds and poor sealing of the intake manifold. When there is a leak in the air supply system, the engine control unit receives inaccurate intake air signals, leading to misjudgment and resulting in unstable idle speed. 2. Poor combustion: Irregular shaking, mild and not severe, with the most noticeable characteristic being that the shaking frequency increases as the fuel level in the tank decreases. This happens because when the fuel system is dirty, impurities with higher density than fuel settle at the bottom of the tank, making the shaking more pronounced as fuel decreases. The fuel pump draws in these impurities along with the fuel, leading to poor combustion in the combustion chamber, which causes the shaking.

What are the tips for reverse parking?

Here is a detailed introduction to the techniques for reverse parking: 1. Identify the starting point: Taking right-side reverse parking as an example, the distance between the car at the starting position and the left line should be 1.2-1.8 meters, the steering wheel should be straight, and the car body should be parallel to the left line. When reversing, use the bottom edge of the left rearview mirror as a reference. When the two coincide, turn the steering wheel fully to the right and continue reversing. 2. Control the corner point: Watch the right rearview mirror. When you spot the corner point of the parking space, pay attention to the changing distance between the corner point and the car body. When the distance is less than 30 cm, turn the steering wheel back halfway and continue reversing. Once the car body enters the parking space and is parallel to the parking line, turn the steering wheel back one full turn. If the distance is not less than 30 cm, do not turn the steering wheel back. Keep reversing until the car body is parallel to the parking line, then turn the steering wheel back one and a half turns at once. 3. Align the stopping point: The stopping point is the parking spot after entering the parking space. The reference method is the same as for the starting point. When you see the bottom edge of the left mirror coincide with the shoulder line of the parking space, stop the car.

How many kilometers should a new car be driven before changing the engine oil?

Here is the relevant introduction about changing engine oil for new car maintenance: 1. Generally speaking, considering the quality of domestic oil, it is more appropriate to change the engine oil at around 8,000 kilometers. 2. Changing the oil at 8,000 kilometers is not suitable for all situations. The replacement time varies depending on the quality of the oil and the road conditions. Full synthetic oil has the longest service life, and it can generally be replaced at around 10,000 kilometers. Semi-synthetic oil can be replaced at 8,000 kilometers. Ordinary mineral oil is recommended to be replaced earlier. 3. If you drive on congested roads for a long time, the working environment of the engine will be harsh, and the cleaning work of the engine oil will also increase. In this case, the oil change cycle may be shortened. When changing the engine oil, remember to replace the oil filter at the same time. A poor-quality oil filter may affect the quality of the engine oil.

Why does the motorcycle sometimes not respond when starting?

Here are the specific reasons why a motorcycle sometimes does not respond when starting: 1. Clutch switch damage. 2. Insufficient battery power. 3. Spark plug gap too large or excessive carbon buildup. 4. Faulty high-voltage cap connected to the spark plug. 5. Damaged starter fuse. Below is extended information on daily motorcycle maintenance methods: 1. Idle speed control: During the break-in period, keep the motorcycle's idle speed at 100 RPM. 2. Gear-speed matching: Match the motorcycle's gear to the speed. 3. Braking method: When braking is needed due to an obstacle ahead, release the throttle, press the rear brake with your right foot, and gently apply the front brake with your right hand. 4. Spark plug installation method: Hand-tighten the new spark plug until it can't be turned anymore, then use a spark plug socket to tighten it an additional quarter to half turn.
