To determine if a vehicle's primer is exposed, run your finger over the scratch. If you feel obvious unevenness or roughness, the primer is likely exposed. Types of primers include: 1. Dip primer; 2. Water-based dip primer; 3. Anodic electrophoretic primer; 4. Cathodic electrophoretic primer. Most passenger cars use cathodic electrophoretic primer, typically in white or gray. Precautions for car touch-up painting: 1. Avoid using water other than soft water, including hot water, alkaline water, or water with high hardness; 2. Do not rinse the car body with high-pressure water streams; 3. Avoid indiscriminate use of cleaning agents; 4. Do not wash the car under scorching sunlight.

Is the Honda Civic's Transmission AT or CVT?

The Civic's transmission is CVT. Below is relevant information about the Civic: 1. Introduction: The Honda Civic comes in a three-door hatchback, a hardtop coupe, a hybrid version, and a five-door sedan version. The Honda Civic launched in China shares the same production platform as the existing Dongfeng Honda model, the Honda CR-V. 2. Exterior: The new Civic largely follows the styling design of the overseas model, featuring full LED headlights. The side profile of the car is more daring than the front, with the C-pillar's smooth transition resembling a coupe, and it adopts 'bracket-style' LED taillights with a dart-shaped light cluster.

What Are the Causes of Car Overheating?

There are many reasons for car overheating. Below is a detailed introduction to the causes of car overheating: 1. Water tank leakage or insufficient antifreeze: This prevents the engine heat from dissipating, and the temperature cannot be reduced in time. 2. Deteriorated antifreeze: The boiling point parameter decreases, affecting the cooling effect; or the anti-rust quality declines, causing blockages in the water tank circulation pipes. 3. High ambient temperature: The air conditioner operates under overload, and radiator components malfunction, leading to engine overheating. 4. Electric fan failure: This results in insufficient fan speed, or damage to the fan shroud, causing severe air leakage.

Can a Rear Bumper Have Internal Damage After Being Hit?

Whether a rear bumper can have internal damage after being hit depends on the situation. Detailed analysis is as follows: 1. If the impact is not severe and there is no visible damage on the surface, there is no need to worry about internal damage. At this point, check if the reverse radar camera is damaged. If it's not damaged, there is generally no issue. If it is damaged, simply claim compensation from the responsible party. This is because the rear of the vehicle has a large energy-absorbing zone. Even without an anti-collision beam, the extensive foam and padding inside can absorb the impact energy. 2. If the rear bumper is severely hit, causing it to dent or break, there may be internal damage. In such cases, it is necessary to visit a 4S shop for a thorough inspection and repairs.

Does driving through deep water in the rain affect the car?

Driving through deep water in the rain can indeed affect your car in several ways: 1. Damage to the car body: When a vehicle gets wet in the rain, water not only remains on the surface but also seeps into the gaps underneath the car. While driving in the rain, road mud can also splash into these gaps. When rainwater mixes with this mud and dirt, it forms a sticky residue that adheres to the gaps, hiding in hard-to-reach areas. If not cleaned properly, this can lead to rust on the car body. 2. Damage to the paint: Rainwater in urban areas generally has high acidity levels. The acidic components in the rainwater can severely corrode the car's paint, causing long-term damage that may be difficult to repair.

Will I get points deducted for driving at 72 in a 60 speed limit zone?

Driving at 72 in a 60 speed limit zone will not result in point deductions, as on roads with speed limits below 60km/h, exceeding the speed limit by less than 50% will not incur penalties, but traffic police may issue a warning. Below are factors affecting vehicle speed limits: 1. Road design speed: This is a standard provided by road design departments, based on specific traffic flow and hypothetical driving conditions. 2. Traffic accident occurrence: This is also an important reference factor in determining maximum speed limits. Sections with frequent accidents should further reduce speed limits within legal and design parameters.

What Causes an SRS Airbag System Malfunction?

SRS airbag system malfunction indicates that the airbag system failed the startup self-test and has existing issues. Relevant information about airbags is as follows: 1. Airbag: A vehicle occupant restraint system that uses cushions designed to inflate rapidly during a collision and then quickly deflate. It consists of an airbag cushion, flexible fabric bag, inflation module, and impact sensor. 2. Principle: During a collision, the vehicle's crash sensors provide critical information to the airbag electronic control unit (ECU), including collision type, angle, and severity. Using this data, the ECU's crash algorithm determines whether the event meets deployment criteria and triggers various ignition circuits to deploy one or multiple airbag modules inside the vehicle.
