SVS indicator light is the engine fault indicator light. Here is more information about SVS: 1. When the SVS light is on, it indicates a fault in the fuel emission system; intake tract fault; spark plug carbon deposit; sensor fault; poor fuel quality; engine carbon deposit; three-way catalytic converter fault; engine knock. 2. When the SVS light is on, you can check whether the oxygen sensor plug is loose; clean the spark plugs; replace the oxygen sensor; replace the three-way catalytic converter; clean the engine; drain the old gasoline from the fuel tank and replace it with high-quality gasoline. 3. SVS, the full English name is Service Vehicle Soon, which translates to "service vehicle as soon as possible." The SVS light is a standard indicator in the automotive industry, responsible for warning of abnormalities in the powertrain system and prompting users to have the vehicle inspected at a service shop. When the powertrain system's self-diagnosis detects an abnormality, it will use the SVS light to prompt the user to have the vehicle inspected. The SVS light alarm may originate from the engine, transmission, or shift control mechanism. When the SVS light flashes, it represents a current fault in the powertrain system, requiring inspection at a service shop; when the SVS light stays on, it represents a historical fault (once occurred) in the powertrain system. In most cases, the historical fault will be automatically repaired by the system, and the SVS light will turn off.

How long does it take to replace the front windshield at a 4S store?

It takes 12 hours to replace the front windshield at a 4S store. Here are the relevant details: 1. Windshield: It is adhered to the car body with glass adhesive. Since the adhesive takes a long time to cure (usually more than 12 hours at room temperature), the car should not be moved until the adhesive is completely dry after replacing the windshield. This prevents issues such as glass misalignment, adhesive failure, or water leakage due to insufficient curing. 2. Precautions: Avoid washing the car for three days after replacing the windshield. Remove the tape securing the windshield position after three days. Try to avoid driving on excessively bumpy roads and refrain from sudden braking or rapid acceleration to prevent windshield displacement. Do not insert parking permits or other cards into the gap between the front windshield and the dashboard.

Why does the radiator keep losing water even though it's not leaking?

The main reasons for a radiator not leaking but constantly losing water include cracks in the water passages, excessively high engine temperature, and coolant leakage. Details are as follows: Cracks in the water passages: Cracks in the engine's internal water passages can cause coolant to enter the cylinders and burn. If the engine is burning coolant, white smoke will come out of the exhaust pipe. Many cars emit white smoke from the exhaust pipe in winter, which is a normal phenomenon. However, if white smoke appears during warmer seasons, it indicates severe coolant burning. Excessively high engine temperature: When the engine operates at excessively high temperatures, it can cause the coolant to evaporate into steam. Coolant leakage: There may be a coolant leak, but the leakage point is very concealed, so the owner hasn't noticed it.

Why is the car in a seized status?

There are several possible reasons why a car may be in a seized status, including outstanding bank payments, owner's debts, or suspected criminal activities. The details are as follows: Outstanding bank payments: For cars purchased through installment plans, if the owner fails to make payments, the bank may apply to the court for debt collection. The court then issues a seizure notice to the vehicle management office, prohibiting all services such as inspections. Owner's debts: For fully paid cars, if the owner has outstanding debts, creditors may apply to the court to first seize the vehicle as a protective measure, and then determine ownership through a court ruling. Suspected criminal activities: If a vehicle is used in criminal activities or purchased with illegal funds, the public security bureau may seize the vehicle to recover it, prohibiting all services such as inspections and transfers.

What are the differences between electric vehicles and traditional cars?

Electric vehicles and traditional cars differ mainly in the following aspects: 1. Different power systems. Traditional cars use diesel or gasoline, while electric vehicles use greener electric energy. Traditional power vehicles are still the mainstream, while electric vehicles will become the trend of future automotive development. 2. Different structures. The structure of traditional cars requires many parts to be combined, while the structure of electric vehicles only needs some wires to be arranged around the body for power supply. 3. Energy supply system. Electric vehicles refer to vehicles powered by on-board power sources, driven by motors to move the wheels, and meeting all requirements of road traffic and safety regulations. Electric vehicles use batteries as energy sources, are driven by motors, and are equipped with speed controllers for speed regulation.
