What does the 'check' light on the car mean?

When the 'check' light appears on your car, it is alerting the driver that there is an issue with the engine system, and the vehicle should be taken to a maintenance facility for inspection. If a sensor or switch in the engine system fails while driving, the computer will use preset values to allow the engine to continue running, while simultaneously illuminating the 'check' or 'check ENGINE' light on the dashboard. The main causes of engine failure include: 1. Dirty throttle body or fuel injectors; 2. Excessive engine carbon buildup; 3. Leaks in the intake system, crankcase ventilation system, or secondary air system; 4. Blocked catalytic converter or faulty oxygen sensor; 5. Use of substandard fuel; 6. Poor combustion conditions.

What causes the antifreeze reservoir to boil over?

The reasons for the antifreeze reservoir boiling over are: 1. The radiator stops functioning, causing the water temperature to become too high; 2. The antifreeze is not circulating, the thermostat is not opening, or the water pump is not working properly, leading to blockage in the water circulation pipeline; 3. Insufficient antifreeze or poor-quality antifreeze with a low boiling point, making it prone to boiling over. The full name of antifreeze is antifreeze coolant, meaning it is a coolant with antifreeze properties. It prevents the coolant from freezing and expanding in cold winter conditions, which could crack the radiator or damage the engine cylinder block or head. Antifreeze is a type of coolant containing special additives, mainly used in liquid-cooled engine cooling systems. It offers excellent performance in preventing freezing in winter, boiling in summer, and protecting against scale and corrosion throughout the year.

Which One is the Brake Pedal?

Location of the brake pedal: 1. Automatic transmission vehicles have two pedals, with the left one being the brake pedal; 2. Manual transmission vehicles have three pedals, with the middle one being the brake pedal. The brake pedal is the pedal that restricts power, i.e., the pedal for the foot brake (service brake), used to decelerate and stop the vehicle. It is one of the most frequently used driving controls in a car, and how the driver operates it directly affects driving safety. The working principle of the brake pedal is: a wheel or disc is fixed on the high-speed shaft of the machine, and corresponding brake shoes, bands, or discs are installed on the machine base, which generate braking torque under external force.

What is the transmission of the Sylphy Classic?

The Sylphy Classic is equipped with two types of transmissions: a 5-speed MT and a CVT. These transmissions are well-matched with the engine, resulting in lower fuel consumption. The transmission is a mechanism used to alter the speed and torque from the engine, capable of fixing or changing the gear ratio between the output and input shafts. The Sylphy Classic is a compact car introduced by Dongfeng Nissan, with dimensions of 4631mm in length, 1760mm in width, and 1503mm in height, and a wheelbase of 2700mm. It is powered by a 1.6L naturally aspirated engine, delivering a maximum power of 90kW and a maximum torque of 155Nm, paired with either a 5-speed manual transmission or a CVT.

What suspension does the Cadillac CT4 use?

Cadillac CT4 uses MacPherson strut independent suspension in the front and multi-link independent suspension in the rear. The car suspension is an important component to ensure ride comfort, and it also serves as a force-transmitting component connecting the frame (or body) with the axle (or wheels), making it a crucial part for driving safety. The Cadillac CT4 is a mid-size car launched by SAIC-GM-Cadillac, with dimensions of 4760mm in length, 1815mm in width, and 1421mm in height, and a wheelbase of 2775mm. It is equipped with a 2.0T turbocharged engine, delivering a maximum power of 174kw and a maximum torque of 350nm, paired with an 8-speed automatic transmission.

How to Check if a Vehicle Has Been in an Accident?

Methods to check if a vehicle has been in an accident include: 1. Inspect the paint: Large-area repainting will result in paint thickness outside the normal range, which can be easily detected with a paint thickness gauge; 2. Examine the front and rear bumpers: Signs of accidents can usually be found on the bumpers. Open the hood and use a flashlight to check for scratches or welding marks; 3. Check the engine compartment: If screws appear to have been turned or there are abnormal wrinkles or dents, further inspection is needed; 4. Inspect the A, B, and C pillars: First, look for obvious dents, then remove the door frame rubber strips to check if the welding points are neat.
