Is the white showing through a black car the primer?

Normally, if white is showing through a black car, it is the primer. Correspondingly, if black is showing through a white car, it is also the primer. It is recommended to check the vehicle's user manual, which will provide relevant information. Bumper primer: The primer for front and rear bumpers, if made of plastic, is black; if not made of plastic, there is no primer. Body and door primer: As for the body and doors, basically any color that differs from the body color is the primer. Related knowledge about car paint: The primer for plastic bumpers is different from that of the car body, as the body uses electrophoresis. Waxing can only increase the smoothness of the paint surface and provides minimal protection to the paint film, but it cannot achieve the effect of repainting.

Does a Car Cover Need Waxing?

While a car cover can minimize the need for additional paint care, waxing is still recommended when possible. Although an invisible car cover reduces the necessity for extra paint maintenance, waxing enhances the cover's anti-stain properties, preventing dust and other contaminants from adhering to it, thereby improving both performance and appearance. Below are the functions of a car cover and precautions to take after installation: Functions of a Car Cover: An invisible car cover primarily protects against dust and acid rain while enhancing aesthetic appeal. Its inherent corrosion resistance is stronger than that of waxing. However, acid rain, insect remains, bird droppings, and accumulated dirt can gradually erode the invisible car cover, affecting the vehicle's surface shine. Therefore, even with a car cover, regular cleaning is essential. For frequent use, washing the car once a month is advised, while less frequent use requires cleaning at least every six months. Precautions After Installing a Car Cover: For the first three days after applying an invisible car cover, avoid waxing or permanent polishing. It is generally sufficient to wax the cover once every two months thereafter.

What Does the Wrench Warning Light Mean?

The wrench warning light is a maintenance indicator, reminding you that it's time for maintenance. Below are the car maintenance intervals and maintenance items: Car Maintenance Intervals: The maintenance interval is preset when the vehicle leaves the factory, so the "small wrench" light will appear after a certain mileage, reminding the driver to perform maintenance in time. Typically, the maintenance interval is every 5,000-8,000 kilometers, while the factory-set interval is slightly longer than 8,000 kilometers. After maintenance, the warning light needs to be reset following a specific procedure to turn it off. If the light remains on after maintenance, simply reset it. Routine Maintenance Items: Engine Oil Maintenance: Engine oil, also known as lubricating oil, helps reduce engine wear and provides cooling and lubrication. There are three types of engine oil: Full Synthetic Oil: Replace every 10,000-12,000 kilometers. If the car is not driven frequently, the oil may emulsify and lose effectiveness, requiring replacement after about a year. Semi-Synthetic Oil: Replace every 8,000-10,000 kilometers. Mineral Oil: Replace every 5,000 kilometers.

What lights should be turned on when temporarily parking?

During the day, no lights are required for temporary parking. At night, temporary parking requires the hazard warning flashers, clearance lights, and rear position lights to be turned on. Hazard warning flashers for temporary parking: The hazard warning flashers, commonly known as 'double flash' (a red triangle with an exclamation mark button switch, also called hazard lights or emergency flashers), are signal lights used to alert other vehicles and pedestrians that the vehicle is in a special situation. Clearance lights for temporary parking: Clearance lights are the outermost lights at the front and rear of the vehicle. Large trucks also have clearance lights on the roof and sides. Front and rear position lights for temporary parking: Front and rear position lights, commonly known as small lights or width indicators, are mainly used to indicate the presence of the vehicle and its approximate width, helping other vehicles make judgments during passing and overtaking.

Where Could the Problem of Car Resonance Be?

Car resonance can be caused by aging rubber in engine mounts, engine misfire, or deformation/improper installation of the engine guard plate. Below are detailed explanations: Aging Rubber in Engine Mounts: If the car has been used for a long time, the high-temperature fatigue aging of the rubber in engine mounts can easily cause resonance, and in severe cases, there may even be bumping and friction noises. Engine Misfire: Engine misfire can also cause resonance in the engine. Deformation or Improper Installation of the Engine Guard Plate: Resonance caused by deformation or improper installation of the engine guard plate is relatively common and easy to resolve.

Can You Still Drive with a Tire Pressure of 196?

A tire pressure of 196 is not suitable for normal driving, and it is recommended to inflate the tires as soon as possible. Low tire pressure increases the contact area between the tire and the ground, leading to abnormal temperature rise inside the tire during driving. Additionally, severe deformation of the tire sidewall accelerates the aging of internal steel wires and fabric layers, increasing the risk of a blowout. It also results in higher fuel consumption and reduced tire lifespan. The relationship between tire pressure and vehicle handling stability: Cornering stiffness is a crucial parameter that determines a vehicle's handling stability. Tires should have high cornering stiffness to ensure good handling stability. Tire pressure is a significant factor affecting cornering stiffness—higher tire pressure increases cornering stiffness, but beyond a certain point, stiffness no longer changes. Introduction to standard tire pressure: According to the international GBT2978-2008 standard, the recommended tire pressures for different types of tires are as follows: Standard tires: 2.4-2.5 bar; Reinforced tires: 2.8-2.9 bar; Maximum pressure: should not exceed 3.5 bar.
