What type of engine oil is suitable for Jetta cars?

Jetta cars use the original 5W-40 semi-synthetic engine oil. Engine oil is a substance enhanced with additives in base oil, primarily containing anti-wear additives, detergents, dispersants, and multi-grade viscosity index improvers. Taking the Jetta VS7 as an example: its length, width, and height are 4624mm, 1841mm, and 1644mm respectively, with a wheelbase of 2730mm, and it is equipped with a 5-speed manual transmission. The trunk capacity of the Jetta VS7 is 548L, the engine's maximum power is 110 kilowatts, the maximum horsepower is 150, and it features tire pressure monitoring, body stability control, brake assist, driver seat belt reminder, and front and rear radar.

How to Replace a Car's Timing Belt?

Car timing belts require regular replacement, typically every 60,000 to 80,000 kilometers. It is best to replace the timing belt at a 4S shop. During replacement, the timing must be properly aligned; otherwise, it may result in the engine losing acceleration power or even failing to start. The engine's timing is crucial as the timing belt drives the camshaft, which controls the opening and closing of the intake and exhaust valves. Incorrect timing can cause irreversible damage to the engine. If the timing belt is not replaced for an extended period, it may eventually break. In such cases, avoid attempting to start the engine as it could further damage the engine.

Is it necessary to clean the fuel system and throttle body?

It is necessary to clean the fuel system and throttle body. Prolonged neglect can lead to a noticeable decrease in engine power and excessive gear shift impact. Below are the relevant introductions about cleaning: Cleaning the throttle body: Removes carbon deposits and gum deposits from the throttle body, ensuring smooth operation, improving fuel economy, making the engine run stronger and more stable, and enhancing driving control. Cleaning the fuel system: Removes deposits in the fuel system, restores normal fuel injection, and eliminates issues such as unstable idling, poor acceleration, hesitation, and knocking. Benefits of cleaning: Reduces fuel consumption, restores the air-fuel ratio, and lowers exhaust emissions.

What is the Function of Lane Departure Warning?

Lane Departure Warning serves to alert the driver when unintentionally (without using turn signals) deviating from the original lane, providing an alarm approximately 0.5 seconds before crossing the lane boundary. This grants the driver additional reaction time, significantly reducing collision risks caused by lane departure. Additionally, LDWS (Lane Departure Warning System) helps correct drivers' habits of neglecting turn signal usage. The system primarily functions to alert drivers experiencing fatigue or inattention due to prolonged monotonous driving. Based on camera installation positions, the system can be categorized into: 1. Side-view system: Cameras mounted on vehicle sides, angled toward lanes; 2. Forward-view system: Cameras installed at the front of the vehicle, angled toward the road ahead.

Does Rain Affect Car Paint?

Rain does affect car paint and can cause corrosion. Rainwater is slightly acidic, and if a car is left wet from rain for an extended period without being washed, the concentration of acidic substances in certain areas can increase, leading to paint corrosion. When rainwater falls on the paint surface, it spreads out due to dust on the car's surface, which turns into mud upon contact with water. This mud can absorb water, forming a film of water on the paint surface. Besides making the car dirtier, this accelerates the erosion of the paint by acid rain. Water stains are often more noticeable on the car's hood because the engine generates significant heat while the car is running, causing rainwater to evaporate quickly and leave marks. If these stains penetrate deeply, waxing alone may not remove them, and professional detailing at an auto beauty shop with a polishing wax may be required.

What kind of lubricant should be used for car door handles?

Car door handles should be lubricated with silicone grease. The car door lock system includes components such as the lock cylinder, lock body, inner handle, outer handle, inner locking mechanism, linkage rod, latch, and striker, many of which require lubrication. Specialized grease with specific properties should be used. The required properties are as follows: Longevity: The door lock mechanism is enclosed within the door and is difficult to maintain, so the grease should provide long-lasting, even lifetime lubrication. Low-temperature resistance: It must maintain lubrication at temperatures as low as -40 degrees Celsius, without solidifying or freezing in winter, which could affect the movement of the lock mechanism. Water resistance and anti-rust properties: Since the door is not a sealed structure, the grease should have good water resistance and prevent rust formation.
