What documents are required for the first car maintenance?

The items needed for the first maintenance include: driver's license; maintenance manual; warranty manual; owner's ID card; vehicle's registration certificate; vehicle's purchase invoice, to be taken to the designated first maintenance facility for the vehicle's initial service. Important note: make an appointment with the 4S shop in advance. The first maintenance refers to the initial service after a new car has been driven, with the specific time varying by vehicle, generally after driving 1,000 to 3,000 kilometers. It is essential to attend the first maintenance on time, neither early nor delayed. The completion of the first maintenance marks the end of the car's break-in period, allowing it to be driven at standard loads and normal speeds as required by the vehicle. The timing for the first maintenance is calculated from the date of vehicle pickup. There are two indicator values for the first maintenance: mileage and time. Whichever comes first will be the standard. The first maintenance items include: changing the engine oil and oil filter, cleaning the air filter, checking various fluid levels for normalcy, inspecting the generator belt and wiper blades for damage, checking tire pressure for normalcy, and examining tires for damage or bulges. Estimated time required: approximately 2 hours to complete all tasks. The most crucial aspect of the first maintenance for a new car is changing the engine oil and oil filter. When changing the oil, the oil filter must also be replaced simultaneously. The selection of engine oil must refer to the "Vehicle User and Maintenance Manual," as different vehicle models specify different oil grades. Maintenance precautions: Do not wash the interior of the car with water: Many people clean their cars during holidays, washing the body with water and wiping it with a cloth. It is important to note that the interior of the car should not be directly washed with water. If the floor mats are dirty, use a vacuum cleaner or take them out to brush with detergent, dry them, and then put them back. There are many ventilation holes under the rubber mats on the floor of the driver's compartment. If water enters, it will not dry but will flow through these holes to areas like the gearbox, causing erosion and corrosion. The best practice is to clean with a vacuum cleaner and then wipe with a cloth to prevent water accumulation. Do not mix different brands of antifreeze: When the antifreeze in the car is low, it is recommended to drain the antifreeze and add the same brand from the start. Since antifreeze brands differ, their chemical properties vary significantly. Various functional additives may corrode others. Different brands of antifreeze use different additives, so they should not be mixed to avoid unnecessary trouble. Do not lubricate tire bolts and nuts: When bolts on a moving car rust, they are often oiled to function again. To prevent rust on wheel bolts and nuts, some people apply lubricant, but this introduces potential safety risks. At high speeds, bolts and nuts may loosen or even fall off, leading to driving failures. Do not press the accelerator when starting an EFI car: The starter of an EFI (Electronic Fuel Injection) car differs from that of a regular car. Its fuel injection control device can automatically adjust the fuel supply based on the starter's temperature and operating conditions, ensuring a smooth start.

What Causes Manual Transmission Car to Shake When Starting?

There are several reasons why a manual transmission car shakes when starting: 1. Normal phenomenon. When the clutch is released to the semi-engaged position, the vehicle will shake, which is a normal phenomenon. This is called the car's creeping phenomenon. If the starting position is on a slope and the accelerator is not pressed, the shaking will be more noticeable. 2. Driver issue, which involves improper coordination between the accelerator and clutch. The accelerator is pressed too lightly or the clutch is released too quickly. The solution is: you can press the accelerator before fully releasing the clutch, which will provide sufficient power to the car, making it easier to start and reducing the shaking. 3. Vehicle malfunction. Problems with the intake system, ignition system, or fuel system can cause the car to shake when starting. For example, clogged fuel lines can cause uneven operation of the engine cylinders, leading to shaking; a dirty throttle can cause intake obstruction and shaking; damaged high-voltage wires or faulty spark plugs can cause unstable engine operation and shaking.

Is the Macan's engine from Volkswagen?

macan's 2.0t model uses Volkswagen's ea888 engine. The following is an introduction to the Macan: 1. In terms of power, the entry-level Macan model is equipped with a 2.0-liter four-cylinder gasoline engine, with a maximum power of 220ps. It takes 7.5 seconds to accelerate from 0 to 100km/h, and the top speed is 230km/h. 2. The entry-level diesel version of the Macan will be equipped with a 2.0-liter turbocharged diesel engine with a maximum power of 190ps. 3. The Macan is a medium-sized SUV. As Porsche's medium-sized SUV, the Macan uses the chassis of the Audi Q5 and comes with Michelin tires as standard. Porsche's family-style front grille is not missing, and the unique hatchback design is fundamentally different from the Q5.

What brand is the torch spark plug?

torch spark plug is a product of the Torch brand, a domestic brand under Zhuzhou Torch Spark Plug Co., Ltd. Where is the spark plug located: The spark plug is installed on the side or top of the engine. In the early days, spark plugs were connected to the distributor via cylinder wires. Over the past decade, most car engines have been modified to have the ignition coil directly connected to the spark plug. What are the effects of a faulty spark plug: If the spark plug is damaged, it can directly cause issues such as leakage in the vehicle's ignition system, increased fuel consumption, and reduced power. The main problem is difficulty in ignition, affecting the normal use of the vehicle. Severe erosion of the spark plug, blistering at the top, damage, or melted and eroded electrodes all indicate that the spark plug is damaged and should be replaced. Steps for replacing the spark plug: Open the hood, lift the engine's plastic cover, remove the high-voltage distributor wires, and mark each cylinder's position to avoid confusion. Use a spark plug socket to remove the spark plugs one by one, ensuring to check for any external debris like leaves or dust and clean them thoroughly. Place the new spark plug into the spark plug hole, hand-tighten it a few turns, then use the socket to tighten it further. Reinstall the removed high-voltage distributor wires according to the ignition sequence and secure the cover.

Why Does the Engine Make Noise After the Car is Turned Off?

Here are the reasons why the engine makes noise after the car is turned off: 1. Cooling sound of the catalytic converter: The normal operating temperature of the catalytic converter is 400-800°C. After the car is turned off, its operation gradually stops, and the temperature drops, causing the internal metal components to expand and contract due to heat, resulting in abnormal noise. 2. Cooling sound of the turbocharger: Normally, the exhaust gas temperature reaches 600-700°C, which accelerates the rapid rotation of the turbocharger and generates friction heat. After the car is turned off, the heat expansion and contraction are also very noticeable, leading to abnormal noise. 3. Uneven cooling of the engine: After driving for a while, the engine temperature is very high. After the car is turned off, the temperature of various components drops, and the heat expansion and contraction cannot be completely uniform, which inevitably causes friction between the internal metal components due to cooling contraction, resulting in abnormal noise. 4. The cooling fan is running: There is no need to worry as it will automatically turn off after the water temperature drops. If the cooling fan is working, it means the engine temperature is still too high, and the fan will continue to operate for one to two minutes.
