How to Remove Dirt from White Car Paint?

White car paint dirt removal methods are introduced as follows: 1. Asphalt: If a large amount of asphalt is adhered to the car body, it can be cleaned with a tar remover. Remember to wear gloves when using the tar remover. 2. Bird droppings and other impurities: For vehicles frequently parked under trees, they are bound to be attacked by bird droppings or tree sap and other impurities. If the stains on the car body are substances like bird droppings, they can be soaked with car shampoo or glass cleaner, and after softening, they can be easily removed. 3. Iron powder: If the stains on the car body are dense iron powder, the above cleaners cannot remove them. Only by using special clay bars or stain removal cloths, and slowly grinding them after washing the car body, can they be removed. (Excessive use of clay bars/cloths may cause the paint surface to lose luster and become dull, so after use, it is advisable to apply a layer of wax to the car body.)

How to Determine if the Drive Shaft Bearing is Faulty?

Here are the methods to determine if the drive shaft is damaged: 1. Damage, wear, deformation, or loss of dynamic balance in the drive shaft can cause abnormal noises and vibrations while driving. 2. During driving, noises may occur when starting or accelerating sharply, accompanied by a feeling of loose components. Below is an analysis of the causes of drive shaft failure: 1. Loose connections (or connecting bolts) at the flange joints of the drive shaft. 2. Loose fixing bolts of the intermediate support bracket of the drive shaft, resulting in excessive clearance between the intermediate support and the intermediate drive shaft journal. 3. Disintegration of the intermediate support bearing of the drive shaft, damage to the bearing raceway, poor bearing lubrication, or excessive wear leading to looseness. 4. Misalignment of the intermediate support bracket installation position, improper adjustment of bearing preload, damage to the rubber spacer ring, or incorrect tightening torque of the intermediate support bracket fixing bolts (either too tight or too loose) causing bracket misalignment, leading to abnormal noises.

How to Use the Foot Brake in an Automatic Transmission Car

Here are the steps to use the foot brake in an automatic transmission car: 1. After the vehicle comes to a complete stop, shift the transmission to the Neutral (N) position. 2. Press down the parking foot brake (this will engage the parking brake) and turn off the engine. 3. After pressing the automatic transmission foot brake, shift the transmission from the N position to the Park (P) position. The method to activate the automatic transmission foot brake is as follows: 1. When starting, first press the brake pedal with your right foot, shift the transmission to the N position, and start the engine. 2. After the engine starts, press the parking foot brake again with your left foot. This will release the parking brake, and the parking foot brake will return to its original position under spring force. 3. Shift the transmission from the N position to the Drive (D) position and slowly release the brake. The vehicle can now move forward.

What is the normal degree of wheel camber angle?

Wheel camber angle is generally between 30 to 40 degrees. Here is some information about wheel camber angle: 1. Camber angle refers to the inclination of the wheel's center plane relative to the vertical line of the ground. 2. A positive wheel camber angle occurs when the upper part of the wheel tilts away from the vehicle's centerline, while a negative angle occurs when it tilts inward. The functions of camber angle are as follows: 1. Camber angle is one of the important factors affecting the size of the tire's contact patch. A zero or slightly negative camber angle ensures that the tire is perpendicular to the ground, maximizing the contact patch area between the tire and the ground. 2. The larger the tire's contact patch, the greater the lateral or longitudinal force the tire can provide, thereby enhancing the vehicle's handling performance. 3. Camber angle significantly impacts tire wear. To minimize tire wear under any driving condition, the wheel's camber angle should be maintained at zero (or slightly negative).

How many liters of brake fluid are generally needed for a change?

Generally, 1~2L of brake fluid is sufficient for a change. Here is some relevant information about brake fluid: 1. As one of the consumables, brake fluid naturally requires regular replacement. When the water content in the brake fluid exceeds 5%, it needs to be replaced promptly. 2. Alternatively, brake fluid should generally be replaced every 40,000 kilometers or every 2 years. During replacement, it is essential to use brake fluid of the same grade as the original. For example, if the original fluid is DOT4, only DOT4-grade brake fluid should be used. 3. When replacing brake fluid, it is important to pay attention to the replacement cycle, which varies depending on different climatic environments. Additionally, the choice of brake fluid is crucial—brake fluids of different brands should not be mixed.
