What Causes Brake Noise When the Car is Cold?

The causes of brake noise when the car is cold are: 1. For new cars, since the brake pads and discs are new and still in the break-in period, they may produce a slight hissing sound, which is normal and usually disappears automatically after a few hundred kilometers; 2. There are foreign objects between the brake pads and discs, such as small particles like sand or small stones entering between them, which can cause a hissing sound; 3. The brake discs and pads are stuck together due to rust, causing noise. This usually happens after driving in the rain and then leaving the car unused for several days. The rust causes the brake discs and pads to stick together, resulting in noise when starting the car again, which is also normal; 4. The brake disc fixing screws are missing or excessively worn, causing a mismatch with the brake pads and resulting in noise; 5. The brake pads are nearly worn out, which may cause a screeching sound. If this occurs continuously for several days and the noise becomes louder and more frequent, it generally indicates that the brake pads are almost worn out and need to be replaced.

How to Solve the Sunroof Noise Issue in the 2018 Magotan?

2018 Magotan sunroof noise solutions are as follows: 1. If there is noise when stationary, it may be due to substandard sealing components; if noise occurs when opening, it could be an issue with the lifting mechanism. 2. Use tissue paper to clean the left and right sliding tracks of the sunroof. Over time, debris particles can accumulate on the tracks, and when the sunroof moves along these tracks, it may rub against the debris, causing noise. Therefore, it is essential to keep the tracks clean. 3. Apply lubricant to both left and right sliding tracks of the sunroof. Spread the lubricant evenly along the tracks, ensuring it is applied precisely within the tracks and not outside. After application, reapply lubricant to the noisy areas to ensure smooth operation. The Magotan measures 4866mm in length, 1832mm in width, and 1464mm in height, with a wheelbase of 2812mm. Its robust V-shaped front grille exudes a steady and imposing presence, complemented by dynamic and stylish streamlined body contours.

Are the Drain Holes of a New Car Opened by the 4S Store?

The drain holes of a new car are already in an open state, so there is no need for the 4S store to open them. Concept: Vehicle drain holes are outlets designed to drain accumulated water from the vehicle during rainy weather. Generally, the drain holes are located in the following areas: the front windshield of the engine compartment, the four corners inside the sunroof, the lower part of the front and rear doors, inside the fuel tank cap, at the bottom of the spare tire in the trunk, and the gaps between the front and rear headlights and the body fenders. Precautions: There is usually a drain hole below the fuel tank cap. If it becomes blocked, water may accumulate in the fuel tank during car washes or rainy weather, potentially causing damage to the fuel tank. The spare tire in the trunk is generally located in a lower part of the body. When driving through water, if the water level rises above the headlights, water may seep into the interior of the vehicle. The drain holes in this area are used less frequently.

How to Determine if a Car's Primer is Exposed?

Gently touch the scratch with your finger; if there is a noticeable unevenness, it indicates that the car's primer has been exposed. Below is an introduction to the primer: 1. Function of the primer: The car primer is a layer of paint applied to the body. Generally, only after the primer is sprayed can the next painting process proceed. As a primer, its primary role is to protect the car body. The primer comes into direct contact with the body, which is mainly made of metal. This requires the primer to have excellent anti-corrosion and anti-rust properties, as well as good adhesion, including adhesion to both the body and the topcoat. 2. Types of primer: Currently, primers can generally be divided into dip primer, water-based dip primer, anodic electrophoretic primer, and cathodic electrophoretic primer. Most passenger cars use cathodic electrophoretic primer, typically in white or gray, depending on the vehicle model. For example, black cars usually use white primer, while white cars opt for gray primer, mainly to make it easier to identify the primer when the paint is scratched. 3. Timely repair of the primer: If a car is scratched, regardless of whether the primer is exposed, it is recommended to repair any deep scratches to prevent rusting over time, which could further affect the appearance. If the metal shell is scratched and the primer is exposed, it will not rust. However, if the metal is exposed, even a small spot, it should be repaired promptly. Otherwise, the affected area may expand.
