Can scratches on the windshield be repaired?

There are two scenarios for repairing scratches on the windshield. Some minor scratches can be repaired, but for large-area scratches, the repair process is quite complex and the results may not be very noticeable. For long and deep scratches within the driver's line of sight, repair is not recommended; instead, it's advisable to replace the entire windshield. Before repairing the scratches, the car glass must be thoroughly cleaned to ensure there are no impurities or debris. Use a cloth to wipe the glass dry, maintaining a dry environment. Small scratches can be removed by polishing. If you don't have specialized equipment, you can apply toothpaste to a small area, rub it back and forth with a towel, then rinse with water to check the effect. If effective, proceed to treat larger scratch areas.

Why is it difficult to start the car after exposure to the sun?

Difficulty in starting a car after prolonged sun exposure can be caused by issues such as a faulty carbon canister purge valve, clogged fuel lines, or a damaged coolant temperature sensor. When experiencing such symptoms, it is advisable to seek repairs at a nearby auto repair shop or 4S store to avoid affecting the normal operation of the vehicle. During prolonged sun exposure, if the carbon canister purge valve remains open, fuel vapor can enter the intake manifold through the carbon canister, leading to an overly rich air-fuel mixture in the engine cylinders, which makes starting the car difficult. Additionally, if the external temperature is too high, the coolant temperature sensor may trigger a protective mechanism to prevent damage to the vehicle, causing the car to remain in a shutdown state. Once the external temperature returns to normal levels, the vehicle can be started normally.

How to Fold Down the Rear Seats in the New Sagitar?

The method to fold down the rear seats in the New Sagitar is: 1. Fasten the seat belt buckle inside the car, then you can push down the rear seats; 2. Open the trunk, and below the glass, you will see two black plastic components in the body grooves, one on each side. Pull the locking mechanism to release and fold down the rear seats. The rear seats can not only be folded down but also have adjustable headrest positions, enhancing driving comfort. The New Sagitar is a model under FAW-Volkswagen, with body dimensions of 4544mm in length, 1760mm in width, and 1461mm in height, and a wheelbase of 2578mm. In terms of appearance, the New Sagitar has abandoned the individuality and sportiness of the old model, adopting a distinctive family-style design. The overall shape is grand and steady, with smooth body lines and refined detailing.

Is It Good to Cover a Car with a Car Cover for a Long Time?

It is good to cover a car with a car cover for a long time. If a vehicle is parked for an extended period, using a car cover can be beneficial. The car cover can effectively protect the car's paint and help control the interior temperature, especially for vehicles with light-colored paint. Prolonged exposure to sunlight and rain can cause the paint to oxidize and turn yellow, so it is advisable to use a car cover when the vehicle is parked for a long time. A car cover is a high-performance, eco-friendly film widely used in the automotive beauty and maintenance industry. It is commonly known as a transparent paint protection film. Once applied, it isolates the car's paint from the air, providing long-lasting protection. Car covers are highly durable, resistant to wear, do not yellow easily, are easy to apply, and can withstand collisions and scratches. They also protect against acid rain, oxidation, and scratches after application.

What is the Purpose of a Central Differential?

The function of the central differential is to allow the two half-shafts to rotate at different speeds, enabling the wheels on both sides to travel unequal distances in a pure rolling motion as much as possible, thereby reducing friction between the tires and the ground. When a car turns, the wheels move in an arc, with the outer wheel necessarily rotating faster than the inner wheel, creating a speed difference. Without a differential, this would cause interference between the driven wheels. Non-driven wheels on either side operate independently without interference. If the driven wheels were rigidly connected by a single axle, both wheels would rotate at the same speed, leading to interference between the inner and outer wheels during turns and making it difficult for the car to turn smoothly. Therefore, modern vehicles are equipped with differentials on their drive axles. Differentials mounted on the front drive axle (front-wheel-drive vehicles) or rear drive axle (rear-wheel-drive vehicles) are referred to as front or rear differentials, respectively. When installed on the central driveshaft of a four-wheel-drive vehicle to regulate the speed difference between the front and rear wheels, it is called a central differential.

What are the symptoms of a bad water pump?

The symptoms of a bad water pump are: 1. A damaged water pump will weaken or even stop the cooling circulation, leading to coolant "boiling over"; 2. Coolant leakage near the water pump area of the engine, with traces of coolant color left on the water pump's ventilation holes, resulting in symptoms like high water temperature due to insufficient coolant; 3. Abnormal noises from the water pump during engine operation, which may be caused by internal foreign objects or bearing wear. The engine drives the water pump bearing and impeller through the pulley, causing the coolant in the water pump to rotate with the impeller. Under centrifugal force, the coolant is thrown to the edge of the water pump housing, generating pressure before flowing out through the outlet or hose. The pressure at the center of the impeller decreases as the coolant is thrown outward, allowing coolant from the radiator to be drawn into the impeller through the hose due to the pressure difference between the pump inlet and the impeller center, achieving a reciprocating cycle of the coolant.
